0:00:02 > 0:00:07THIS PROGRAMME CONTAINS SOME SCENES WHICH VIEWERS MAY FIND DISTURBING.
0:00:19 > 0:00:21'We read stories in flesh and blood and bone.
0:00:25 > 0:00:27'We piece together lives from residue.
0:00:30 > 0:00:32'And every one of those lives is unique,
0:00:32 > 0:00:34'except in one respect...
0:00:36 > 0:00:39'...that each of us wants to love and be loved.
0:00:40 > 0:00:43'Because if we don't connect,
0:00:43 > 0:00:46'then we just move through the world like breath in the air
0:00:46 > 0:00:48'and we're nothing.'
0:01:16 > 0:01:19'Reports are coming in of violent outbreaks
0:01:19 > 0:01:20'And at least one known death
0:01:20 > 0:01:22'at Langdon Vale Prison.
0:01:22 > 0:01:24'No details have been released as yet
0:01:24 > 0:01:29'and the prison authorities insist they are regaining control after several hours of rioting.'
0:01:33 > 0:01:34'Langdon Vale was first established as an open prison
0:01:34 > 0:01:36'exclusively for women offenders
0:01:36 > 0:01:39'and has, until now, enjoyed a trouble-free reputation,
0:01:39 > 0:01:43'which makes this sudden outbreak of violence all the more surprising.'
0:01:47 > 0:01:49Her name's Beth Fox.
0:01:49 > 0:01:51Somebody got into her cell last night, slit her throat, et cetera.
0:01:51 > 0:01:53- No witnesses.- Et cetera?
0:01:53 > 0:01:55Yeah, body's a mess. It's not pretty.
0:01:55 > 0:01:57INDISTINCT SHOUTING
0:02:01 > 0:02:03Hi. Jim Ryan. Governor.
0:02:03 > 0:02:06Dr Eve Lockhart. How come somebody could just get into her cell?
0:02:06 > 0:02:09Well, it's an open prison, they have their own keys.
0:02:09 > 0:02:11We've got a suspect.
0:02:11 > 0:02:13There was a spat last night between the victim and another prisoner -
0:02:13 > 0:02:15- Nicole...- Henderson.
0:02:15 > 0:02:18She's like top hen in the coop.
0:02:18 > 0:02:19I've seen the CCTV footage.
0:02:19 > 0:02:22She batters the victim over the head with a pool cue,
0:02:22 > 0:02:24but that doesn't account for the state of the body.
0:02:26 > 0:02:29WOMEN SHOUT
0:02:35 > 0:02:37This door was locked, yeah, when you found the body?
0:02:37 > 0:02:38Yeah, yeah, yeah, from the outside.
0:02:38 > 0:02:42We searched the place. There was no key in the cell.
0:02:46 > 0:02:48My God.
0:03:00 > 0:03:02Look, I'm gonna have to get you out of here. I thought we'd secured the floor.
0:03:02 > 0:03:04No, no, no, we need to get the body back to the Farm
0:03:04 > 0:03:06as quick as we can for autopsy.
0:03:06 > 0:03:10No-one's gonna stick around here longer than it's safe to.
0:03:34 > 0:03:37Have you ever seen bruising like this before?
0:03:37 > 0:03:38No. Swelling, I have.
0:03:38 > 0:03:40A body'd been left in front of a gas fire for a week
0:03:40 > 0:03:43and blew up like a beach ball.
0:03:43 > 0:03:45Right...
0:03:48 > 0:03:51We've got no outward signs
0:03:51 > 0:03:53of sexual assault.
0:03:53 > 0:03:55We've got rice-water diarrhoea staining.
0:03:55 > 0:03:57- Eve?- Oggy, do you want to...?
0:03:57 > 0:04:00Yep, hello? Is everything all right there? Under control?
0:04:00 > 0:04:03I think so. They seem contained, at least. Listen...
0:04:03 > 0:04:07- The blood on the floor here. - Are you getting this, Eve?
0:04:07 > 0:04:11There's no spray pattern whatsoever, which suggests to me...
0:04:11 > 0:04:13The heart had already stopped pumping when the artery was cut.
0:04:13 > 0:04:16Why cut someone's carotid when they're already dead?
0:04:16 > 0:04:18There's no obvious signs of a struggle.
0:04:18 > 0:04:19Well, there was massive bruising.
0:04:19 > 0:04:21Yeah, evenly distributed over...
0:04:21 > 0:04:2480% of her body with no clear trauma sites.
0:04:24 > 0:04:25Yeah, except for this.
0:04:31 > 0:04:34Well, Hale said she was hit over the head with a pool cue,
0:04:34 > 0:04:37so that makes sense.
0:04:37 > 0:04:39One identifiable injury.
0:04:45 > 0:04:48This way, girls.
0:04:48 > 0:04:50And you're sure it's safe?
0:04:50 > 0:04:53Everyone's banged up in their cells apart frae half a dozen up on the roof.
0:04:53 > 0:04:56Eh, and before you ask, I'm no' risking going up there to get them,
0:04:56 > 0:04:59- no' with news cameras watching. - Tell me about Nicole Henderson.
0:04:59 > 0:05:01She's coming to the end of an eight for trafficking.
0:05:01 > 0:05:04- You said she's top dog here, yeah? - She's a bloody nightmare.
0:05:04 > 0:05:07Always feels the need to, you know, challenge authority.
0:05:07 > 0:05:10Sees herself as the union rep, as it were.
0:05:10 > 0:05:12So on paper, you run the place,
0:05:12 > 0:05:14but actually, she's the one wears the trousers, right?
0:05:14 > 0:05:17What was her relationship with Beth Fox like?
0:05:17 > 0:05:19Nicole had a girlfriend in here,
0:05:19 > 0:05:21until Beth came and broke it up. PHONE RINGS
0:05:21 > 0:05:22What was her name?
0:05:22 > 0:05:24Tess Williams.
0:05:24 > 0:05:26I'll have to take this. My line boss.
0:05:26 > 0:05:28Ryan?
0:05:29 > 0:05:33No, no. No. no. No, it's under control. Everything's under control.
0:06:05 > 0:06:08What happened?
0:06:08 > 0:06:10Er, screws took her to the infirmary.
0:06:12 > 0:06:15No, I meant what happened to cause the fight?
0:06:17 > 0:06:19Look, I've spoken to Jim Ryan.
0:06:19 > 0:06:21He reckons you're the cock of the prison.
0:06:21 > 0:06:24You don't want to believe everything Jim Ryan tells you.
0:06:24 > 0:06:26- Because?- Because he's a knob-head.
0:06:26 > 0:06:29He wants me transferred out and he'll do anything to make that happen.
0:06:29 > 0:06:33Did she say something to you? Beth? Did she scare you?
0:06:33 > 0:06:34Oh, yeah(!)
0:06:34 > 0:06:36Yeah, I was shitting myself.
0:06:36 > 0:06:39That's why I smacked her over the head with a pool cue.
0:06:39 > 0:06:43- OK. Is that Tess Williams? - Um... Yeah.- Your ex?
0:06:43 > 0:06:47- I'm not a dyke.- Oh, no(!) Just all these years in prison - needs must, I understand.
0:06:47 > 0:06:49So, you and Tess, you're all sweet,
0:06:49 > 0:06:52Beth comes along, takes her off your hands.
0:06:52 > 0:06:56- Ooh. You have to go after her with a big stick, don't you? - We went our separate ways ages ago.
0:06:57 > 0:06:58Again...
0:06:58 > 0:07:01what was the problem last night, Nicole?
0:07:01 > 0:07:04Beth. Beth's the problem.
0:07:04 > 0:07:08She's insecure, takes it out on people she's close to.
0:07:08 > 0:07:11Eh, I bet you know all about that one, don't you, eh?
0:07:11 > 0:07:15Mm? You don't like yourself very much, do you, eh?
0:07:15 > 0:07:18Why you ended up stuck here, doing this shitty job.
0:07:18 > 0:07:22Yeah, thank you. So, what you're telling me is, Beth and your ex, Tess, they had an argument
0:07:22 > 0:07:26- and you decided to step in and play the Good Samaritan?- Yep.
0:07:26 > 0:07:30Oh, come along! You're gonna have to give me something a bit better than that, my love! Hm?
0:07:30 > 0:07:33What do you think I am? Some kind of bloody monkey?
0:07:37 > 0:07:40- Tell me about Tess.- What do you want to know? She's up on the roof.
0:07:40 > 0:07:44- You can nip up there and ask her yourself. - Is she violent?- No.- Never?
0:07:47 > 0:07:51She does what she wants, she goes her own way.
0:07:52 > 0:07:54She's not frightened of anything...
0:07:54 > 0:07:56or anybody.
0:07:58 > 0:08:01Everybody works for everybody else in here.
0:08:01 > 0:08:03So, if you've got a deal happening, you've gotta share.
0:08:03 > 0:08:06There is no deal. Nothing that concerns you, anyway.
0:08:06 > 0:08:10- It's all right, I'm fine. - What we had is history.
0:08:10 > 0:08:14And if you've got a problem with that, take it out on me, not Beth.
0:08:14 > 0:08:15Come on.
0:08:27 > 0:08:31Look, I know what you're thinking, but I never killed anybody.
0:08:32 > 0:08:33I don't have that kind of form
0:08:33 > 0:08:38and I do not hold that kind of grudge.
0:08:48 > 0:08:51These are Beth's clothes for examination.
0:08:51 > 0:08:53Also, there were two different hair samples on her pillow.
0:08:53 > 0:08:54We're gonna need to take DNA profiles,
0:08:54 > 0:08:56staff included, to see who that hair belongs to.
0:08:56 > 0:08:59Well, the prisoners' DNA is on the police database.
0:08:59 > 0:09:03Be just as quick to make your own. I have to go to a judge to access the records.
0:09:03 > 0:09:05- OK, let's do bloods and screen for toxins while we're there.- OK.
0:09:08 > 0:09:11And anything you may have on Beth, Tess, Nicole,
0:09:11 > 0:09:12- can you send to me and to the Farm?- Sure.
0:09:12 > 0:09:15- Now, Tess is still on the roof, right?- There's eight of them up there.
0:09:15 > 0:09:17Yeah, I need her down.
0:09:17 > 0:09:18I told you...
0:09:18 > 0:09:20She's a suspect. I don't care
0:09:20 > 0:09:23- what it looks like on television. - I can't make that decision.
0:09:23 > 0:09:26Dragging women off the roof, all that bollocks. I need her down here, I need to talk to her now.
0:09:26 > 0:09:28My boss is on the way. Speak to him.
0:09:28 > 0:09:30Mike, if you're gonna do a sweep of the cells,
0:09:30 > 0:09:33can you prioritise Nicole Henderson and Tess Williams, thank you.
0:09:48 > 0:09:51Mike, whoever cut Beth's carotid, there may be blood traces on clothes.
0:09:51 > 0:09:53- Yeah, yeah, we're on to it. - Also her throat.
0:09:53 > 0:09:56It wasn't stabbed as such,it was more like...a careful incision
0:09:56 > 0:09:59with something small, like a modelling knife.
0:09:59 > 0:10:02Well, there's no sign of a knife here. I mean, not yet.
0:10:02 > 0:10:05It looked like she'd been severely beaten, but there are no impact sites.
0:10:05 > 0:10:07Really? You sure about that?
0:10:07 > 0:10:09Yeah, of course I am. I wouldn't say it otherwise.
0:10:09 > 0:10:12Oggy...
0:10:12 > 0:10:14The tox screen on Beth's blood?
0:10:14 > 0:10:17- I'm in the middle of it right now. - What, there?
0:10:17 > 0:10:19I'm sorry you've had to come looking for me.
0:10:19 > 0:10:21- No, no, I didn't mean that. - But I like it here, OK?
0:10:21 > 0:10:23I mean, why not?
0:10:23 > 0:10:26I'm usually on my own in there, I might as well be on my own out here.
0:10:26 > 0:10:28- Do you want me to stay and do it with you?- It's fine.
0:10:28 > 0:10:30SHE SIGHS
0:10:30 > 0:10:35OK. Well, er, let me know as soon as you have anything, right?
0:10:39 > 0:10:42- 'Good night.'- 'Good night.'
0:10:58 > 0:10:59Am I a suspect?
0:10:59 > 0:11:01You'll have to ask the police.
0:11:01 > 0:11:02I'm asking you.
0:11:02 > 0:11:04I just do the science.
0:11:05 > 0:11:07What are you so frightened of, hmm?
0:11:07 > 0:11:09Me?
0:11:12 > 0:11:14CHUCKLES
0:11:14 > 0:11:17Would you be frightened if you saw me on the street, or is it just this place?
0:11:17 > 0:11:20I wouldn't see you on the street, would I?
0:11:20 > 0:11:24Oh, you might do. We all go out to work here.
0:11:24 > 0:11:27I might call on you one day.
0:11:28 > 0:11:32So, what is it that you do... for work?
0:11:32 > 0:11:35Oh! Heh! Like you give a shit.
0:11:40 > 0:11:42All right.
0:11:42 > 0:11:44I work for a chippy.
0:11:44 > 0:11:47Beth was in a caff on the river.
0:11:47 > 0:11:49Tess works for a cleaning company.
0:11:49 > 0:11:52There's no such thing as a free lunch here, you know.
0:11:52 > 0:11:54We all stand by one another.
0:11:58 > 0:12:00It's OK, you know.
0:12:02 > 0:12:04You can talk to me. I'm not the police.
0:12:04 > 0:12:06I do.
0:12:06 > 0:12:07I stand by people, me.
0:12:13 > 0:12:15Tess...
0:12:15 > 0:12:16What?
0:12:19 > 0:12:22Well, she can be so focused, like, so...
0:12:24 > 0:12:26..single-minded.
0:12:27 > 0:12:30She'd have to be, to do what she did to...
0:12:31 > 0:12:34..get put away in the first place.
0:12:38 > 0:12:40I can forgive her owt, me. Hmm.
0:12:40 > 0:12:42Mm.
0:12:42 > 0:12:45She taught me things about myself.
0:12:48 > 0:12:51She reminded me of who I was,
0:12:51 > 0:12:53that it's OK to care about people.
0:12:56 > 0:12:58Hmm.
0:12:58 > 0:12:59Hm.
0:13:02 > 0:13:04INDISTINCT SPEECH
0:13:06 > 0:13:07Hurry up!
0:13:27 > 0:13:28Why'd you do that?
0:13:28 > 0:13:30Huh!
0:13:30 > 0:13:32To see what you'd do.
0:13:32 > 0:13:34- Oggy, are you there?- Whoa!
0:13:34 > 0:13:38Oggy? Oggy, I just e-mailed you over some CCTV footage.
0:13:38 > 0:13:42Can you research the attached medical files?
0:13:52 > 0:13:55Counselling tape of Tess Williams.
0:13:55 > 0:13:58I'm trying to find out what your primary state of mind is here.
0:13:58 > 0:14:01Well, we need sustenance, don't we?
0:14:01 > 0:14:04We need to be inspired to see beyond these four walls.
0:14:04 > 0:14:06And, at the risk of sounding ungrateful,
0:14:06 > 0:14:10there are very few people I can connect with in here.
0:14:10 > 0:14:12I feel alone most of the time.
0:14:12 > 0:14:13I suppose my studies are a way
0:14:13 > 0:14:16of smuggling something real and good inside me.
0:14:16 > 0:14:18It's like medicine.
0:14:24 > 0:14:27'Time isn't measurable in terms of experience.
0:14:27 > 0:14:30'I mean, sometimes an hour can seem interminable,
0:14:30 > 0:14:33'but if, say, you're with somebody that you love, then...
0:14:33 > 0:14:35'it's elastic.'
0:14:35 > 0:14:38'Sure, but maths deals in measurable absolutes.'
0:14:38 > 0:14:41'No, no. Not always.
0:14:41 > 0:14:43'It's not that easy to explain.'
0:14:43 > 0:14:44'OK.'
0:14:47 > 0:14:50'What I'm trying to find out is, what exactly does this do for you,
0:14:50 > 0:14:54'besides it being an intellectual challenge?'
0:14:54 > 0:14:55'Oh, right.
0:14:57 > 0:14:58'Well, that's simple.
0:14:58 > 0:15:01- 'Maths is the window into other worlds...' - Mike, whose cell are you in?
0:15:01 > 0:15:03Tess Williams.
0:15:03 > 0:15:05TESS CONTINUES SPEAKING ON RECORDING
0:15:05 > 0:15:07What is she, some kind of mathematician?
0:15:07 > 0:15:09'..in quite the way that we experience them.'
0:15:09 > 0:15:12'And that mirrors what goes on in your head, yeah?
0:15:12 > 0:15:15'Other dimensions that don't obey normal rules?
0:15:17 > 0:15:21'That dimension where you take your sister's pain away?'
0:15:21 > 0:15:26Oggy? You must have the results of the tox screen by now, surely.
0:15:26 > 0:15:28- Oggy?- Oh, yeah. Nothing's come up.
0:15:31 > 0:15:34- Do you want me to invent something? - No, I just want you
0:15:34 > 0:15:38to focus on what's important, rather than watching prison TV.
0:15:41 > 0:15:43Oh, strewth!
0:15:43 > 0:15:44Mike?
0:15:44 > 0:15:46Yeah.
0:15:46 > 0:15:49I need your help here. I'm looking at sections of Beth's skin
0:15:49 > 0:15:51and some of the arterials have burst close to the surface.
0:15:51 > 0:15:53Well, that would explain the bruising.
0:15:53 > 0:15:55So, what caused the damage, then?
0:15:55 > 0:15:57I don't know. Nothing chemical.
0:15:57 > 0:15:59Not what we've tested for anyway.
0:15:59 > 0:16:00- Bacteria maybe?- Maybe.
0:16:00 > 0:16:02- Tests are still ongoing.- Well,
0:16:02 > 0:16:04it could be a natural toxin. There were some native things here -
0:16:04 > 0:16:06moonseed, monkshood,
0:16:06 > 0:16:07wolfsbane.
0:16:07 > 0:16:11Just focusing on what's important here, but has anyone looked on Tess's bookshelves?
0:16:15 > 0:16:17Eve, have a look at this.
0:16:21 > 0:16:23She's a very clever girl.
0:16:23 > 0:16:24- Aye, got a PhD.- Where'd she do that?
0:16:24 > 0:16:27- Here?- Within the prison system.
0:16:27 > 0:16:29- Did a BSc and then a Masters. - What in?
0:16:29 > 0:16:33- Eh, maths.- Where was she before? - She started off at, er,
0:16:33 > 0:16:36- Cookham Wood Young Offenders. - How old was she?- 16.
0:16:36 > 0:16:40Then onto Rampton, treated for psychosis with delusional something or other.
0:16:40 > 0:16:43- Then back into the general prison population.- What did she do?
0:16:43 > 0:16:46Her younger sister had a disease, cystic fibrosis.
0:16:46 > 0:16:49Tess got it into her head that she wisnae gonna survive
0:16:49 > 0:16:53if she wisnae with her 24 hours a day, so... They say she nursed her with total dedication
0:16:53 > 0:16:55then one day just snapped.
0:16:55 > 0:16:58Tried to suffocate her. Put her out her misery.
0:16:58 > 0:17:00- She still dangerous? - Unpredictable, maybe.
0:17:00 > 0:17:02OK, violent?
0:17:02 > 0:17:03- Mike?- Yeah, go ahead, Eve.
0:17:03 > 0:17:06Rice-water diarrhoea and poor skin turgor - ring any bells?
0:17:06 > 0:17:08Who exactly do I have to talk to in order to get her off the roof?
0:17:08 > 0:17:10Sorry, excuse me, gents.
0:17:10 > 0:17:12Well, that could be a variety of things.
0:17:12 > 0:17:15OK, you wouldn't normally get bruising and swelling like this,
0:17:15 > 0:17:18so God knows, but the bacteria screen has come back positive.
0:17:18 > 0:17:20What for?
0:17:20 > 0:17:21Vibrio cholerae.
0:17:21 > 0:17:23Cholera?!
0:17:32 > 0:17:34'Sooner or later, you're gonna come back late
0:17:34 > 0:17:38'from whatever it is that you're doing and Ryan over there
0:17:38 > 0:17:41'is gonna use you to pretend that he's got a big dick.'
0:17:41 > 0:17:42'So, what are you saying?'
0:17:44 > 0:17:46You need more time out there, right?
0:17:46 > 0:17:47I can fix it.
0:17:47 > 0:17:50We go to work, we clock in, we clock out - there's no leeway on time.
0:17:50 > 0:17:54There is if you go to college evening classes.
0:17:54 > 0:17:55I know people who'll sign you up.
0:17:55 > 0:17:57You don't have to actually go,
0:17:57 > 0:18:02but if anyone asks, they'll say that's where you are.
0:18:02 > 0:18:03Buys you time.
0:18:03 > 0:18:06What, and you'd do that just to be nice? Don't think so.
0:18:06 > 0:18:08No.
0:18:10 > 0:18:13Making money, aren't you, hm?
0:18:13 > 0:18:16Little nest egg for when you get out.
0:18:18 > 0:18:20Tell me about it.
0:18:20 > 0:18:22Cut me in.
0:18:33 > 0:18:35Just how infectious is this exactly?
0:18:35 > 0:18:37OK, listen to me, right?
0:18:37 > 0:18:39You cannot get this from person to person.
0:18:39 > 0:18:41You get it from food and water.
0:18:41 > 0:18:44So, kitchens are closed, right? Nothing whatsoever in or out.
0:18:44 > 0:18:46Bottled water only.
0:18:46 > 0:18:49And we're gonna need blood samples from all the inmates and the staff.
0:18:49 > 0:18:51OK?
0:18:54 > 0:18:57One more time, loud and clear. I need Tess Williams.
0:18:57 > 0:19:01- How many times do I have to tell ye?!- Shh! So what's it gonna take, hm?
0:19:01 > 0:19:04People dying of cholera before you get off your arse?
0:19:04 > 0:19:06Not with news cameras, OK?
0:19:06 > 0:19:08Oh, so you're gonna wait until we bus them out in ambulances?
0:19:08 > 0:19:10Really?
0:19:10 > 0:19:12- And how d'you think that's gonna make your public image look?- Hm?
0:19:12 > 0:19:16DI Hale? I'm from the Home Office. Parvez Khan.
0:19:16 > 0:19:19At last! Somebody who might be able to make a decision!
0:19:27 > 0:19:29INDISTINCT SHOUTING
0:19:32 > 0:19:35SCREAMING
0:19:44 > 0:19:46Tess Williams? Tess?
0:19:46 > 0:19:47Tess Williams?
0:19:47 > 0:19:50- Tess Williams? Tess!- Get off!
0:19:50 > 0:19:52Tess Williams...?
0:19:52 > 0:19:54Get off me!
0:19:56 > 0:19:59There's no-one else up there. Where is she?
0:19:59 > 0:20:01Huh? Where is Tess Williams?
0:20:13 > 0:20:16So, what do you want to do? Issue a public health warning?
0:20:16 > 0:20:19Something tells me the Home Office isn't gonna want to do that.
0:20:19 > 0:20:22Country's safe in their hands and all.
0:20:22 > 0:20:24Since when did we get cholera in the UK?
0:20:24 > 0:20:29So, how the hell did she pick it up, then? A day trip to West Bengal?
0:20:37 > 0:20:40Guys, the hairs Rosa found on Beth's pillow...
0:20:40 > 0:20:42They match with Tess Williams.
0:20:42 > 0:20:43OK, I'm on my way.
0:20:43 > 0:20:46We can place Tess in Beth's cell.
0:20:46 > 0:20:49Fantastic(!) And can you place where Tess is now?
0:20:49 > 0:20:52- She's up on the...- On the roof? No. Wrong. She's not there, she never has been.
0:20:52 > 0:20:55- So who told you she was?- Nicole!
0:20:58 > 0:21:00So she's not on the roof and she didn't go to work. Vanished!
0:21:00 > 0:21:03You'd better come up with something quick, man! Think!
0:21:03 > 0:21:05She could have just walked out of here really, couldn't she?
0:21:05 > 0:21:07This is an open prison, you know.
0:21:07 > 0:21:09The doors are open at 6am for people in work placements.
0:21:09 > 0:21:11Next of kin, have you contacted them?
0:21:11 > 0:21:12Her parents are dead.
0:21:12 > 0:21:15The sister - still alive?
0:21:15 > 0:21:16I don't know.
0:21:16 > 0:21:18What's her name?
0:21:18 > 0:21:19Eh, Caitlin.
0:21:19 > 0:21:20Do you have an address for Caitlin?
0:21:20 > 0:21:22There'll be nothing in the system. It was years ago,
0:21:22 > 0:21:25and as far as I know, there's been no contact since she was sentenced.
0:21:25 > 0:21:27All right, listen - my concern is we've got somebody out there
0:21:27 > 0:21:29- running around with cholera. - No, we don't know that for certain.
0:21:29 > 0:21:30OK. Maybe cholera, then.
0:21:30 > 0:21:32Transmission person to person is extremely rare,
0:21:32 > 0:21:35so she's not gonna give it to anyone else outside.
0:21:35 > 0:21:38Fine. But if it was cholera that killed Beth Fox,
0:21:38 > 0:21:40we're not looking at murder any more, am I right?
0:21:40 > 0:21:42Look, she was dead before she was cut and yes,
0:21:42 > 0:21:45she had cholera in her system, but this is extremely important, OK?
0:21:45 > 0:21:48Cholera doesn't cause bruising and swelling...
0:21:48 > 0:21:51- He asked a simple question. - Yeah, and I'm trying to explain. - Look, we don't want an essay.
0:21:51 > 0:21:56All we want is a very simple answer, because to be quite honest with you,
0:21:56 > 0:22:00- I'm fed up with running about looking like a bloody idiot. - There are no simple answers.
0:22:00 > 0:22:02We make an observation suggesting one thing
0:22:02 > 0:22:04and then it's immediately contradicted by something else.
0:22:04 > 0:22:06It takes time to come up with scientific proof.
0:22:06 > 0:22:11You can't just throw a paddy and expect results, Hale - you have to learn some patience.
0:22:11 > 0:22:16All right, let's just assume for one moment it was cholera that killed her and Tess has it too.
0:22:16 > 0:22:19Now, worst-case scenario - say the police can't find her quickly,
0:22:19 > 0:22:21and it remains untreated. How long will she have?
0:22:21 > 0:22:25The closest strain to what we found in Beth is El Tor 01,
0:22:25 > 0:22:28a Haitian strain which can kill within anything from 2 to 48 hours.
0:22:28 > 0:22:33Hello? Hello, it's Hale. I need an address. Caitlin Williams.
0:22:35 > 0:22:36As quick as you can.
0:22:39 > 0:22:41We test everyone.
0:22:41 > 0:22:44If anyone else is carrying it, they go straight onto antibiotics.
0:22:44 > 0:22:47Except Tess Williams. How are you gonna test her?
0:22:47 > 0:22:49- She's not here, is she? - So, find her.
0:22:49 > 0:22:52All right, whatever. For now, we keep this under wraps, OK?
0:22:52 > 0:22:55Nobody here needs to know about this. We can't afford a panic.
0:22:58 > 0:23:02You knew she wasn't up on the roof. You were stalling.
0:23:02 > 0:23:05Is that what this riot is about, to cover her getting out the front door?
0:23:05 > 0:23:07She didn't tell me anything.
0:23:07 > 0:23:11Now, you said that Beth was really hard work, right?
0:23:11 > 0:23:14That she was really insecure? She gave Tess a hard time.
0:23:14 > 0:23:16- I never said that. - So, Tess comes to you,
0:23:16 > 0:23:18she says, yeah, we've had a fight,
0:23:18 > 0:23:21she lost control, but she didn't mean to actually kill her.
0:23:21 > 0:23:24She's in pieces and she needs time to get away
0:23:24 > 0:23:28before they discover the body, will you help? Nicole, will you help?
0:23:28 > 0:23:31So, you stir things up. You put a couple of people up on the roof
0:23:31 > 0:23:35because you know that Ryan over there is too soft to go up and get 'em down,
0:23:35 > 0:23:38and by the time that we do, she's had, what, a three-hour head start?
0:23:38 > 0:23:42I need to know where Tess is, Nicole. Where is she?
0:23:45 > 0:23:47BUZZ OF CONVERSATION
0:23:51 > 0:23:55'Well, we all need sustenance, don't we? Whoever we are.'
0:23:55 > 0:23:57- She's fascinating.- That's one way of describing her.
0:23:57 > 0:24:00Takes something special, I suppose, to cut somebody's throat.
0:24:00 > 0:24:03- She was already dead. - Well, that's all right, then(!)
0:24:03 > 0:24:06'There are few people I can connect with in here.'
0:24:06 > 0:24:08Would you do that to somebody you say you love?
0:24:08 > 0:24:10'I feel alone most of the time.
0:24:10 > 0:24:11'I suppose my studies are a way
0:24:11 > 0:24:14'of smuggling something real and good inside me.
0:24:14 > 0:24:16'It's like medicine.'
0:24:16 > 0:24:17RECORDING REWINDS
0:24:17 > 0:24:19'It's like medicine.'
0:24:28 > 0:24:32Rosa, can you check if Tess gave blood in the last few days?
0:24:32 > 0:24:35I don't know, routine drug screening, whatever.
0:24:35 > 0:24:37I've got to test her somehow.
0:24:37 > 0:24:41I've gotta find out what we've got walking around out there.
0:24:41 > 0:24:44Mike, I'm couriering a faeces sample from Tess's cell.
0:24:44 > 0:24:47If she has cholera, she'd have D and V, right?
0:24:47 > 0:24:49It'd show up in her faeces.
0:24:49 > 0:24:51- Can you scan it?- Yeah, will do.
0:24:51 > 0:24:54Also, I'm thinking we might need some expert help here.
0:24:54 > 0:24:57A specialist in tropical diseases.
0:24:57 > 0:24:59Well, I know someone at university might be able to help.
0:24:59 > 0:25:01His name's, um, Neil Olsen.
0:25:01 > 0:25:03- Do you want me to get in touch? - Yeah.
0:25:03 > 0:25:05No... No.
0:25:05 > 0:25:09Actually, let's just hang fire, see how widespread this is.
0:25:13 > 0:25:16These are from her cell, right? Her sister, Caitlin.
0:25:16 > 0:25:20Caitlin, Caitlin, Caitlin... Completely obsessed with her.
0:25:20 > 0:25:22- So obsessed she tried to kill her? - Yeah. But there was a kind of noble logic to that.
0:25:22 > 0:25:24Did she survive, the sister?
0:25:28 > 0:25:30Yeah.
0:26:01 > 0:26:03'I suppose my studies are a way
0:26:03 > 0:26:06'of smuggling something real and good inside me.
0:26:06 > 0:26:08'It's like medicine.
0:26:10 > 0:26:12'I get the faintest glimpse of other dimensions
0:26:12 > 0:26:15'where things don't obey the rules of the universe
0:26:15 > 0:26:16'in quite the way that we experience them.'
0:26:16 > 0:26:19'And that mirrors what goes on in your head, yeah?
0:26:19 > 0:26:22'Other dimensions that don't obey normal rules?
0:26:22 > 0:26:25That dimension where you take your sister's pain away?
0:26:25 > 0:26:29- 'Tell me about Caitlin.' - 'Like I said,
0:26:29 > 0:26:31'every breath she took gave her pain.
0:26:31 > 0:26:33'I used to hear her screaming for someone to take it away.'
0:26:33 > 0:26:36- 'Where were your parents?' - 'My dad was next to useless.
0:26:38 > 0:26:39'My mum was...
0:26:39 > 0:26:41'impotent, like me.'
0:26:41 > 0:26:43'Except you weren't, though, were you?'
0:26:43 > 0:26:46- 'She wanted to be free of it.' - 'Would you do it again?'
0:26:46 > 0:26:49- 'I thought she was better off dead.' - 'Yes, I realise that.
0:26:49 > 0:26:52'What I'm asking is, would you do it again?'
0:26:52 > 0:26:54'Yeah, I'd do it again. Course I would.
0:26:54 > 0:26:56'Both our parents are dead now.
0:26:56 > 0:26:59'Without question, she's solely my responsibility.
0:26:59 > 0:27:02'So, if she was hurting that badly, then yeah, whatever it takes.'

0:27:28 > 0:27:29Sorry.
0:27:29 > 0:27:31I am here.
0:27:31 > 0:27:33Hello?
0:27:33 > 0:27:34Hello?
0:27:44 > 0:27:47'Time isn't measurable in terms of experience.
0:27:47 > 0:27:50'I mean, sometimes an hour can seem interminable,
0:27:50 > 0:27:54'but if, say, you're with somebody that you love, then it's elastic.
0:27:54 > 0:27:56'It's not that easy to explain.'
0:27:56 > 0:27:58'OK.
0:27:59 > 0:28:04'What I'm trying to find out is, what exactly does this do for you?
0:28:04 > 0:28:06'Besides being an intellectual challenge.'
0:28:31 > 0:28:33Hi, sorry, you're needed.
0:28:33 > 0:28:37Khan needs to make a public statement and he needs information.
0:28:37 > 0:28:42'Attempts are being here to move press and public away from the area,
0:28:42 > 0:28:44'but so far, no explanation has been forthcoming.
0:28:44 > 0:28:48'We are experiencing a really distressing scene. You can feel the tension here.'
0:28:48 > 0:28:52- Turn that shit off.- 'I will, of course, keep you updated.'
0:28:52 > 0:28:54Right, once again, simple question.
0:28:54 > 0:28:56Is this murder?
0:28:56 > 0:28:58And likewise, once again, for everyone's benefit,
0:28:58 > 0:29:04she had cholera in her system, and her carotid artery was cut postmortem.
0:29:05 > 0:29:08- Why is this so difficult to answer? - Because...
0:29:08 > 0:29:11I can't give you an absolute yes or no yet.
0:29:11 > 0:29:14Right now, we don't even understand how the cholera got into the building,
0:29:14 > 0:29:17and it's not behaving as I would expect, so...
0:29:17 > 0:29:20All right, you just listen to me, yeah? Just so you understand.
0:29:20 > 0:29:23I have the Home Secretary on my back about this.
0:29:23 > 0:29:26See, this is not some little incident
0:29:26 > 0:29:28that you can handle in your own sweet way.
0:29:28 > 0:29:30Now, I have to hand them a bone,
0:29:30 > 0:29:33but I can't until I get something more than supposition from you,
0:29:33 > 0:29:36- and you are being paid handsomely... - Do you want me to make something up
0:29:36 > 0:29:40to get the press off your back? Is that what you want me to do? Do you?
0:29:40 > 0:29:43I'm as frustrated as you are, but I...
0:29:43 > 0:29:46I can only deal with the evidence I have,
0:29:46 > 0:29:48and if that's not good enough for you,
0:29:48 > 0:29:52then I suggest you pick up the phone and get someone else.
0:29:52 > 0:29:54No, no, no. No-one's asking to do that.
0:29:54 > 0:29:57PHONE RINGS
0:29:57 > 0:29:59Hale.
0:30:01 > 0:30:04Do we know yet if any of the other inmates have been infected?
0:30:04 > 0:30:05No, we don't.
0:30:05 > 0:30:09As soon as we do, you'll be the first to know.
0:30:09 > 0:30:12Good. Good, fantastic.
0:30:12 > 0:30:15Found Tess's sister's address.
0:30:15 > 0:30:16Yeah, go on.
0:30:17 > 0:30:19- Eve?- Yeah, go ahead, Mike.
0:30:19 > 0:30:21I got some results on the blood and faeces tests.
0:30:21 > 0:30:23- Yep?- I'm still working my way through them,
0:30:23 > 0:30:25- so my results are inconclusive... - OK, I'll be right there.
0:30:25 > 0:30:26..but I thought you might want to know.
0:30:26 > 0:30:30So far, only one more prisoner has tested positive for V cholerae. It's Tess Williams.
0:30:30 > 0:30:33- How long has she got?- I don't know. Depends when she was infected.
0:30:33 > 0:30:37Hours at most. That's if antibiotics will even work against this thing. That's if we can even find her.
0:30:37 > 0:30:41So, you're just gonna give her a death sentence?
0:30:41 > 0:30:43I've also finished tests on the food and water - they're both clear
0:30:43 > 0:30:45so the infection couldn't have come in that way.
0:30:45 > 0:30:48Then it has to have been brought in by Tess and Beth,
0:30:48 > 0:30:50picked up somewhere outside the prison.
0:30:52 > 0:30:54See you in a bit.
0:31:13 > 0:31:15Move over.
0:31:15 > 0:31:17- Tess, what are you doing? - Shut up, please.
0:31:17 > 0:31:19ENGINE STARTS
0:31:19 > 0:31:21Look, she's a good person, OK? She's decent.
0:31:21 > 0:31:23- Yeah, and we'll find her. - How? How are you gonna find her?
0:31:23 > 0:31:26- Well, Hale...- Hale?! Hale wouldn't know where to start.- Oggy...
0:31:26 > 0:31:30- She is way ahead of him. She's cleverer than him, she's much more capable than him...- Please.
0:31:30 > 0:31:32- Calm down.- Are you still there, Mike?
0:31:32 > 0:31:35- Yeah, I'm listening. Please... - She just wants to make things right.
0:31:35 > 0:31:37I'm guessing Beth and Tess both had jobs outside the prison.
0:31:37 > 0:31:39- She wants to make things right! - Shut up!
0:31:39 > 0:31:43Will you please shut up, please?!
0:31:46 > 0:31:49That's it. That's it, that's it.
0:31:49 > 0:31:50'We all need sustenance, don't we?'
0:31:50 > 0:31:53Did, um...
0:31:53 > 0:31:54Beth and Tess, did they work together?
0:31:54 > 0:31:56No.
0:31:56 > 0:31:58Well, they must have got it from the same source, surely.
0:31:58 > 0:31:59Mike, is this a new strain?
0:31:59 > 0:32:01Well, I dunno.
0:32:01 > 0:32:03We need to break it down, we have to identify it
0:32:03 > 0:32:07so that we know how to treat it. If it's not El Tor 01 Haitian strain, then what is it?
0:32:07 > 0:32:10'I get the faintest glimpse of other dimensions where things don't obey
0:32:10 > 0:32:13'the rules of the universe in quite the way that we experience them.'
0:32:13 > 0:32:18'And that mirrors what goes on in your head, yeah?
0:32:18 > 0:32:22'Other dimensions that don't obey normal rules?
0:32:22 > 0:32:25'That dimension where you take your sister's pain away?'
0:32:25 > 0:32:28You're not getting out of here, so just stop it.
0:32:28 > 0:32:30SIGHS
0:32:33 > 0:32:36- PHONE RINGS - Oh, yeah, hang on.
0:32:38 > 0:32:39Yep, hi.
0:32:39 > 0:32:40Her boyfriend says she should've been back ages ago.
0:32:40 > 0:32:42Well, did she tell him where she was going?
0:32:42 > 0:32:44Yeah, just to the local shops.
0:32:44 > 0:32:46Well, why'd she want to see her sister?
0:32:46 > 0:32:49My guess is she came back to see Caitlin to...do whatever it was that she failed to do years ago.
0:32:49 > 0:32:52She knows she's got 48 hours.
0:32:52 > 0:32:53- Less than 48 hours.- What?
0:32:53 > 0:32:55Well, we don't know precisely when she was infected.
0:32:55 > 0:32:59What precisely do you know, then, Eve? Cos the clock is ticking here.
0:32:59 > 0:33:02Hey! It's your job to find her, not mine. I'm just doing the science.
0:33:02 > 0:33:06- Is that right? Well, not that I'd have noticed.- Excuse me?
0:33:06 > 0:33:09- PHONE BEEPS - THERAPIST: 'Tell me about Caitlin.'
0:33:09 > 0:33:12'You mentioned what things were like when you were at home.'
0:33:12 > 0:33:15'Like I said, every breath she took gave her pain.'
0:33:15 > 0:33:17- Oggy.- 'I used to hear her screaming...'
0:33:17 > 0:33:20You need to put your head somewhere else, OK?
0:33:20 > 0:33:22'My dad was next to useless.
0:33:24 > 0:33:26'My mum was...
0:33:26 > 0:33:27'impotent, like me.'
0:33:27 > 0:33:30'Except you weren't, though, were you, ultimately?'
0:33:30 > 0:33:34- 'She wanted to be free of it...' - Jeez!
0:33:47 > 0:33:49So, how are you feeling?
0:33:51 > 0:33:52Fantastic(!)
0:33:59 > 0:34:01- What else do you want me to say? - The truth?
0:34:04 > 0:34:07- D'you know, the last time I saw you, years ago...- I know.
0:34:07 > 0:34:08Yeah.
0:34:09 > 0:34:12..I woke up and you asked me the same question.
0:34:12 > 0:34:14And you want me to be honest with you now?!
0:34:14 > 0:34:17And what are you gonna do with that information, Tess?
0:34:17 > 0:34:19Are you gonna go away and write me a letter
0:34:19 > 0:34:21saying you hope I feel better soon, is that what you're gonna do?
0:34:21 > 0:34:24Or are you gonna try and make things better right here and now,
0:34:24 > 0:34:26- like you did last time? - So, when you wake up at night,
0:34:26 > 0:34:29- who's taking care of you?- Me. I am.
0:34:29 > 0:34:30No-one else?
0:34:30 > 0:34:33Why is that so important now, all of a sudden?
0:34:35 > 0:34:38Cos you know, I haven't spoken to you since I was a child.
0:34:42 > 0:34:46What happened, happened, and we both had to deal with the consequences.
0:34:50 > 0:34:52So, what are you gonna do?
0:34:52 > 0:34:55Cos after years and years of prison and psychiatrists
0:34:55 > 0:34:57and God knows what else...
0:34:58 > 0:35:01..it's still in you, isn't it?
0:35:04 > 0:35:08Well, d'you know something? Whatever warped shit is driving you on,
0:35:08 > 0:35:09I've survived you before.
0:35:11 > 0:35:12I beat you and I'm still here.
0:35:14 > 0:35:16And I am actually a grown-up.
0:35:16 > 0:35:17- No, you're still my...- No!
0:35:17 > 0:35:19I'm an adult.
0:35:19 > 0:35:21No, you're still my responsibility.
0:35:21 > 0:35:23I'm all you've got.
0:35:24 > 0:35:25No.
0:35:25 > 0:35:26Yeah.
0:35:26 > 0:35:30And even when Mum and Dad was around, it was all down to me, and you know it.
0:35:33 > 0:35:37I found some plant debris in Tess's cell, dandelion seeds,
0:35:37 > 0:35:39and there's something else I need to ID.
0:35:39 > 0:35:41Mike, have you had a look at Beth's clothes?
0:35:41 > 0:35:44- I haven't had time yet, Rosa. - Oh, come on, Mike!
0:35:48 > 0:35:49Eve?
0:35:51 > 0:35:55OK, look, I'm sorry. It's just that we are running out of time.
0:35:55 > 0:35:57What, and you think I don't know that?
0:35:57 > 0:36:00Look, the balance of probability
0:36:00 > 0:36:02is that something to do with cholera killed her, right?
0:36:02 > 0:36:04Yeah, agreed.
0:36:04 > 0:36:05So, why stab her after she's dead?
0:36:07 > 0:36:08Most likely because Tess
0:36:08 > 0:36:12had to convince Nicole to help her get away, and the easiest way to do that
0:36:12 > 0:36:15was to claim that she had actually killed Beth. Now, listen - what I'm thinking is...
0:36:15 > 0:36:16It's a donkey.
0:36:18 > 0:36:21So, you're saying she stabbed her because she was a donkey, is that right?
0:36:21 > 0:36:24No, this is. It's what geneticists call a donkey. The cholera's man-made,
0:36:24 > 0:36:27- It's a manufactured genetic mutation.- I don't understand.
0:36:27 > 0:36:30It's not a natural strain of the disease, it's been made in a lab for medical purposes.
0:36:30 > 0:36:33Here. The bacteria's been deactivated to make it safe
0:36:33 > 0:36:36then modified to carry medication directly to a target.
0:36:36 > 0:36:38Look, if you had a tumour, this would deliver the chemo straight to it.
0:36:38 > 0:36:41Tess kind of triggered the thought for me, listen.
0:36:41 > 0:36:47'I suppose my studies are a way of smuggling something real and good inside me.
0:36:47 > 0:36:48'It's like medicine.'
0:36:48 > 0:36:53"Like medicine." That's literally what this was designed to do.
0:36:53 > 0:36:54OK, slow down.
0:36:54 > 0:36:58What you're saying is that this donkey, or whatever, is the real cholera.
0:36:58 > 0:37:02Yes, it's just been redesigned, which is why it didn't behave
0:37:02 > 0:37:05like regular cholera would. Just think of it like a donkey carrying a load of medicine on its back.
0:37:05 > 0:37:06Yeah, but there is no load here.
0:37:06 > 0:37:09No, because I think this was just an experiment to see how
0:37:09 > 0:37:12the modified bacteria would react to being injected into the host.
0:37:12 > 0:37:14The load was gonna be added later.
0:37:14 > 0:37:17So, the cholera was somehow reactivated when it was introduced to Tess and Beth?
0:37:17 > 0:37:19- Yes. - How?
0:37:19 > 0:37:22- I have no idea.- So, this isn't about cholera at all.
0:37:22 > 0:37:23It's about something else entirely.
0:37:23 > 0:37:25I mean, cholera's just the agent.
0:37:25 > 0:37:31- No, look... - So...so, why cholera? Why use that?
0:37:31 > 0:37:34That's my limit. We wanna know more, we have to get a geneticist on board.
0:37:34 > 0:37:37Not on this budget, we won't. Can't afford expertise, can we, Inspector?
0:37:37 > 0:37:40What are you trying to do, Mike? Hm? Bleed me dry?
0:37:40 > 0:37:44I don't believe I'm hearing this. Are we actually trying to save this woman's life here
0:37:44 > 0:37:45or is it all about costs and profit?
0:38:11 > 0:38:13Hey. You're overreacting.
0:38:13 > 0:38:16That was for Hale's benefit, to get more money out of him.
0:38:16 > 0:38:17- It's just a game they play. - Funny kind of game.
0:38:17 > 0:38:20He wouldn't deny us expert help, not at this stage.
0:38:24 > 0:38:27I don't want to have to examine Tess's dead body.
0:38:28 > 0:38:29Why?
0:38:32 > 0:38:34I don't know.
0:38:34 > 0:38:36Maybe because...
0:38:36 > 0:38:37we're so similar.
0:38:39 > 0:38:42Her mind takes her to places she doesn't wanna to go, so does mine.
0:38:42 > 0:38:45She's locked up, so am I. We're both...
0:38:48 > 0:38:50..we're both on our own.
0:38:50 > 0:38:53You can't know someone from looking at images of them.
0:38:53 > 0:38:57Evidence and observation - it's what we do.
0:38:57 > 0:38:59I've watched her in therapy, Eve.
0:38:59 > 0:39:01Hey, listen to me.
0:39:01 > 0:39:03If this gets personal, it'll only confuse things.
0:39:03 > 0:39:07Anyway, the truth is, you're not connecting with who she actually is,
0:39:07 > 0:39:11- just who you think she is.- No. - Yes, you are. Which is kind of typical bloke.
0:39:11 > 0:39:12Really?
0:39:12 > 0:39:19Look, I think she is passionate and selfless and that there is a goodness in there.
0:39:19 > 0:39:23- She said she'd harm her sister again if she got the chance.- No.
0:39:23 > 0:39:27- She did, in therapy. I've just watched it.- You are wrong. - She's dangerous.
0:39:27 > 0:39:28No!
0:39:28 > 0:39:31- Oggy...- No, you can't see her because...
0:39:31 > 0:39:33Because what?
0:39:35 > 0:39:36OK, look.
0:39:37 > 0:39:41I have got a skin that's paper thin and you, you're the opposite,
0:39:41 > 0:39:42you know?
0:39:43 > 0:39:46She's not like either of us.
0:39:46 > 0:39:48Whatever bad stuff has happened to her,
0:39:48 > 0:39:51she's not frightened to say when she's wrong.
0:39:51 > 0:39:55She's not afraid of getting close to people like you are.
0:40:00 > 0:40:04Eve, the contact at the university I was telling you about, Neil Olsen.
0:40:04 > 0:40:05Um, he...
0:40:05 > 0:40:08Do you want me to go and see him or do you want to do it?
0:40:08 > 0:40:10Thanks.
0:40:22 > 0:40:23Tess...
0:40:24 > 0:40:28I'm gonna be all right. I'm on the list for a transplant...
0:40:28 > 0:40:30Oh, and what if you don't get it?
0:40:30 > 0:40:32What then? More infections, more pain?
0:40:32 > 0:40:36Yeah, but that, that is my decision, isn't it? That's my life.
0:40:40 > 0:40:42Tess, I don't need you or anybody.
0:40:42 > 0:40:45You see, that's where you're wrong and that is what worries me.
0:40:45 > 0:40:47Because it's all right being independent,
0:40:47 > 0:40:49but what are you gonna do when you really, really need help?
0:40:49 > 0:40:51Ben.
0:40:51 > 0:40:55- He'll tire of it, Caitlin. He will. - No, he won't.- He will.
0:40:55 > 0:40:57- Everyone does.- And did you?- No.- No.
0:40:57 > 0:41:01But you did what you thought was for the best for me.
0:41:01 > 0:41:03But you were wrong, Tess, weren't you?
0:41:12 > 0:41:14OK.
0:41:15 > 0:41:16Just listen to me.
0:41:21 > 0:41:23The truth is...
0:41:23 > 0:41:26I need to be able to just go, but I can't unless...
0:41:26 > 0:41:28Unless!
0:41:28 > 0:41:31Unless you know that I've got someone to look after me?
0:41:31 > 0:41:33Yeah.
0:41:37 > 0:41:39Is that what all this is all about?
0:41:46 > 0:41:48For God's sake.
0:41:49 > 0:41:52Yes, I'm with someone that I love
0:41:52 > 0:41:53and who loves me.
0:41:56 > 0:41:59You probably won't understand this, but this is what normal people do.
0:42:00 > 0:42:02They take care of each other.
0:42:04 > 0:42:06I don't need you, so you can go...
0:42:06 > 0:42:09go and do whatever it is that you need to do,
0:42:09 > 0:42:12but just leave us to get on with our lives, please.
0:42:13 > 0:42:15OK.
0:42:21 > 0:42:23If we're testing some sort of hypothesis,
0:42:23 > 0:42:25- don't you think I should know? - Sure, just...
0:42:25 > 0:42:27Eve questions everything I say, so I want to be certain
0:42:27 > 0:42:31before I start making any announcements, so...please?
0:42:31 > 0:42:33Just the lungs?
0:42:33 > 0:42:34Yeah.
0:42:35 > 0:42:39Um, first I wanna know what's going on with you and Eve.
0:42:39 > 0:42:42Nothing. We just had a difference of opinion.
0:42:42 > 0:42:45Eve is very...anal-ytical.
0:42:45 > 0:42:47- CHUCKLES - And you're not?
0:42:47 > 0:42:49No, I... Well, maybe.
0:42:49 > 0:42:56- But not exclusively, you know. I...I'm open to other aspects of us that make us who we are.- Such as?
0:42:56 > 0:42:59Eve sees things very simply, you know. For her, it's just cause and effect.
0:42:59 > 0:43:02This happens here and that happens there,
0:43:02 > 0:43:04and somehow it all leaves an evidence trail
0:43:04 > 0:43:07and all we have to do, Oggy, is be clever enough to find it.
0:43:07 > 0:43:10Get to the point. This difference of opinion, that's about this girl, Tess, innit?
0:43:13 > 0:43:14Yeah.
0:43:17 > 0:43:18Look...
0:43:18 > 0:43:21I believe people can recover
0:43:21 > 0:43:24and people can be motivated to do right by others
0:43:24 > 0:43:26and the particular thing you did at a particular time
0:43:26 > 0:43:28shouldn't damn you for the rest of your life.
0:43:28 > 0:43:31Look, I'm sorry to bring you both back to basics,
0:43:31 > 0:43:33but, um...I've finished testing Beth's clothes
0:43:33 > 0:43:36and there is plant material on it,
0:43:36 > 0:43:38maybe the same as you found in Tess's cell.
0:43:38 > 0:43:40Er, would you mind, Rosa?
0:43:40 > 0:43:42Yeah, yeah, I'll be right there.
0:43:44 > 0:43:45(Sorry.)
0:43:45 > 0:43:47All right, go. It's fine.
0:43:54 > 0:43:56In my head these last few years...
0:43:58 > 0:44:00..I've always been here with you.
0:44:01 > 0:44:02I know.
0:44:05 > 0:44:07But we have to move on. Both of us.
0:44:15 > 0:44:18And this responsibility thing that I keep talking about...
0:44:21 > 0:44:23Well, it makes you do strange things.
0:44:25 > 0:44:27It becomes like an obsession.
0:44:34 > 0:44:36I only ever wanted to help you.
0:44:38 > 0:44:40I hope you know that.
0:44:49 > 0:44:51But there's been a price to pay.
0:44:54 > 0:44:56And it's not just for me.
0:45:01 > 0:45:02So, like you say...
0:45:04 > 0:45:05..it's time we moved on.
0:45:05 > 0:45:07Enough.
0:45:11 > 0:45:12Enough.
0:45:14 > 0:45:16It's time it all stopped.
0:45:26 > 0:45:28LOCK CLUNKS
0:46:03 > 0:46:06BUZZ OF CHATTER
0:46:06 > 0:46:10Er, Professor Olsen? Excuse me, I'm so sorry.
0:46:10 > 0:46:12- I'm Dr Eve Lockhart.- Oh, hello.
0:46:12 > 0:46:15This DI Hale. We need to talk to you somewhere private.
0:46:15 > 0:46:17Is there somewhere suitable we could go?
0:46:17 > 0:46:20Excuse me. Um, come this way, please, it's more private.
0:46:20 > 0:46:22Dr Fields, could you join us?
0:46:25 > 0:46:28Yeah, I work in genetics. It's part of what I do.
0:46:28 > 0:46:33We think it's genetically modified V cholerae.
0:46:36 > 0:46:40- Modified for what purpose? - That's what we're hoping you can tell us.
0:46:40 > 0:46:44- We found it postmortem in a local patient.- Contracted in this country? - It appears so, yes.
0:46:44 > 0:46:47This woman, have you seen ever her before?
0:46:48 > 0:46:51- Was she the person infected? - Yeah, it was.- No.
0:46:51 > 0:46:53What about that one?
0:46:53 > 0:46:55No.
0:46:57 > 0:47:01Thank you. Look, does anyone else do this kind of work here?
0:47:01 > 0:47:04- There's a whole department. - There's people all over the country.- No, I said here.
0:47:04 > 0:47:05These women, they can't travel.
0:47:05 > 0:47:08Well, if the question is am I responsible for this work,
0:47:08 > 0:47:10then the answer's no - I'm not doing any research right now.
0:47:10 > 0:47:13If you want confirmation of that, check with the IREC.
0:47:13 > 0:47:15- The ethics committee. - PHONE RINGS
0:47:15 > 0:47:19- Research has to be approved and registered.- I'm sorry, but we're needed.
0:47:19 > 0:47:20You're needed here. We need help.
0:47:20 > 0:47:23- I'm making a speech.- Hello?
0:47:23 > 0:47:25- We're running out of time. Please. - Where?
0:47:26 > 0:47:27My details.
0:47:27 > 0:47:31- Send me what else you've got, I'll look at it tonight.- Right.
0:47:31 > 0:47:33Jim Ryan, they've got another suspected case of cholera.
0:47:33 > 0:47:35OK, thank you.
0:47:38 > 0:47:41She's positive - same strain as Tess and Beth.
0:47:41 > 0:47:44But she's not to be told, OK? We don't want a panic.
0:47:44 > 0:47:47What, you don't think she's got a right to know what's going on with her own body?
0:47:47 > 0:47:52- No, no, she forfeited that right when she was sent down. - Big hairy bollocks. Tell you what.
0:47:52 > 0:47:55This is now a police investigation and members of the public...
0:47:55 > 0:47:58are not invited. Thank you very much.
0:48:08 > 0:48:11OK, this is what happened.
0:48:11 > 0:48:13Tess killed Beth, showed you the body,
0:48:13 > 0:48:15you stuck a couple of women on the roof to buy her time.
0:48:15 > 0:48:18Tactical genius, me.
0:48:18 > 0:48:20Tess told you that they'd had a fight and she'd stabbed her, right?
0:48:20 > 0:48:22Wrong.
0:48:22 > 0:48:27She was stringing you along. Beth was already dead by the time she knifed her.
0:48:32 > 0:48:33Why would she do that?
0:48:33 > 0:48:36- Why would she lie to me? - Like I said, to get you to help her.
0:48:38 > 0:48:40Nicole...
0:48:40 > 0:48:43Beth died of cholera.
0:48:43 > 0:48:44And you've got it.
0:48:46 > 0:48:49Tess has got it too, and she knows it.
0:48:51 > 0:48:55If she knew she's got cholera, then why would she just leave?
0:48:55 > 0:48:57She would get help. Why would she leave?
0:48:57 > 0:49:00Because she can't live without her girlfriend?
0:49:00 > 0:49:03Because she wants to go and see her sister before she dies?
0:49:03 > 0:49:05You tell me. Whatever, the clock is ticking
0:49:05 > 0:49:07and the longer you hold out on me,
0:49:07 > 0:49:10the less chance she has of surviving, and it's also true for you.
0:49:13 > 0:49:15Tell me about the cholera, then.
0:49:15 > 0:49:18You must've all got it from the same source.
0:49:21 > 0:49:25Why should I help her? She lied to me.
0:49:25 > 0:49:27Because you told me she's a good person
0:49:27 > 0:49:29and she taught you how to care about people.
0:49:31 > 0:49:32You owe her this.
0:49:34 > 0:49:36I don't know where she's gone, I swear. I swear.
0:49:36 > 0:49:38Look...
0:49:39 > 0:49:43This is, um... This is an engineered version of the disease.
0:49:43 > 0:49:47It's not responding to treatment.
0:49:47 > 0:49:51You and Tess will both need help. And that's why we need to find whoever planted it in you.
0:49:53 > 0:49:55OK.
0:49:55 > 0:49:58Tess got me and Beth involved in drug trials.
0:49:58 > 0:50:00What were they for?
0:50:00 > 0:50:01I don't know.
0:50:01 > 0:50:04Who conducted the trials? Was it Professor Olsen?
0:50:04 > 0:50:10Some woman in his department. But I don't remember her name.
0:50:12 > 0:50:13I'll be fine, right?
0:50:14 > 0:50:16Please find her.
0:50:16 > 0:50:18We will.
0:50:21 > 0:50:22I'm gonna go and get you some help.
0:50:22 > 0:50:24No.
0:50:24 > 0:50:26Look, if this gets out,
0:50:26 > 0:50:29they're gonna transfer you back to maximum security.
0:50:29 > 0:50:32We won't see each other again.
0:50:32 > 0:50:34Look...
0:50:34 > 0:50:37we'll just... we'll get out in the morning and we'll sort it then, OK?
0:50:40 > 0:50:42OK.
0:50:42 > 0:50:43Try and get some rest.
0:50:45 > 0:50:48- PHONE RINGS - Yep, go ahead, Oggy.
0:50:48 > 0:50:51What part of the body does cholera target?
0:50:51 > 0:50:53Primarily the small intestine. Why?
0:50:53 > 0:50:55Definitely not the lungs, because we've just examined Beth's lungs
0:50:55 > 0:50:57and there's a massive concentration of V cholerae there.
0:50:57 > 0:50:59I don't understand that.
0:50:59 > 0:51:03Because the lungs are the target. The donkey was programmed to carry the medication there.
0:51:03 > 0:51:04Why the lungs?
0:51:04 > 0:51:07- Because Tess's sister has... - Has cystic fibrosis. Of course.
0:51:07 > 0:51:09They were treating cystic fibrosis.
0:51:09 > 0:51:11Yeah, but I still don't understand it. I mean,
0:51:11 > 0:51:14- why cholera specifically? - OK, two reasons.
0:51:14 > 0:51:16Firstly, it's very fast-acting, and secondly,
0:51:16 > 0:51:18because they have a natural resistance to it.
0:51:18 > 0:51:19It's a safe option.
0:51:19 > 0:51:23Cystic fibrosis sufferers can carry the cholera in the blood
0:51:23 > 0:51:25and not actually suffer from the disease.
0:51:25 > 0:51:27Look, Eve, I am sorry, but I was right and you were wrong.
0:51:27 > 0:51:31Tess is not a threat to anybody. She only got involved to help her sister.
0:51:31 > 0:51:32Yeah, well done, Oggy!
0:51:32 > 0:51:34Have you checked, is anyone up at the university
0:51:34 > 0:51:36researching cystic fibrosis?
0:51:47 > 0:51:49Right now, no-one.
0:51:49 > 0:51:52But a Dr Fields ran out of money last year.
0:51:52 > 0:51:53Same department as Olsen.
0:51:59 > 0:52:02Right, we know the bacteria's been engineered.
0:52:02 > 0:52:03One woman has already died.
0:52:03 > 0:52:06Over here. Look, please.
0:52:15 > 0:52:17Two more are infected. We're into damage limitation.
0:52:17 > 0:52:20I don't know anything about this, I swear.
0:52:20 > 0:52:23- Oh, come on.- Look, it's very simple.
0:52:23 > 0:52:26I have witness statements implicating you. Either they're lying or you are.
0:52:26 > 0:52:30We need your help to resolve this before anyone else is affected.
0:52:35 > 0:52:36OK.
0:52:38 > 0:52:43I met Tess when I tutored her on her first degree at Holloway.
0:52:43 > 0:52:45I bumped into her a few months back.
0:52:45 > 0:52:49The cleaning company she works for have a contract here.
0:52:49 > 0:52:52And you thought because you knew Tess and Caitlin's history,
0:52:52 > 0:52:54you'd get them to take part in an unregistered trial.
0:52:54 > 0:52:56SCOFFS Neil knows
0:52:56 > 0:52:59I was perfecting a system for delivering medication.
0:52:59 > 0:53:02- I didn't know about these trials. - No, but I'm sure you'll agree,
0:53:02 > 0:53:05- this is massively beneficial.- Did you tell Tess it was unregistered?
0:53:05 > 0:53:09Absolutely, yes, and she was all for it, for Caitlin.
0:53:09 > 0:53:12I mean, do you realise how difficult it is to get funding right now?
0:53:12 > 0:53:14- Strangely enough, I do, yeah. - Look,
0:53:14 > 0:53:17I deactivated the modified cholera bacteria
0:53:17 > 0:53:20before injecting it into the test subjects.
0:53:20 > 0:53:22I mean, obviously they have no natural immunity.
0:53:22 > 0:53:25I had no idea that the bacteria would reactivate.
0:53:25 > 0:53:27If I did, I would've called a halt to the trial.
0:53:27 > 0:53:29And the subjects would've been in touch, surely, if there was a problem?
0:53:29 > 0:53:32They were in prison. It's not that easy.
0:53:32 > 0:53:34I'm sorry.
0:53:34 > 0:53:36So, why has it reactivated?
0:53:36 > 0:53:40Possible contact with protein cell receptors, I don't know. I'll have to look into it.
0:53:40 > 0:53:43Your cholera is not responding to tetracycline or doxycycline.
0:53:43 > 0:53:47We could try a combination high dose of tetramethoprim
0:53:47 > 0:53:50and sulphamethoxazole - we should start there.
0:53:50 > 0:53:52OK. I'm gonna call the prison.
0:53:52 > 0:53:56Um... if I could come with you, I could maybe help.
0:53:56 > 0:53:58The women are presumably in the hospital.
0:53:58 > 0:53:59Nicole is.
0:54:01 > 0:54:03Did you pay any of them?
0:54:03 > 0:54:05Nicole I did, not the other two.
0:54:05 > 0:54:07They weren't in it for the money.
0:54:07 > 0:54:12We were all trying to do something decent.
0:54:13 > 0:54:14Yep.
0:54:22 > 0:54:23Beth.
0:54:25 > 0:54:27Beth?
0:54:30 > 0:54:31(Beth?)
0:54:57 > 0:55:00We found Tess's sister.
0:55:00 > 0:55:02- She's OK.- And Tess?
0:55:04 > 0:55:08- Well, what are you doing?! You have to find her! - You think we're not trying?
0:55:08 > 0:55:12We've looked everywhere that she's got a connection with. We're running out of options, mate.
0:55:22 > 0:55:25I've made an analysis from the plant debris on Beth's clothes
0:55:25 > 0:55:28and we've got a match with one of the samples from Tess's cell.
0:55:28 > 0:55:29I've just got to ID it.
0:55:34 > 0:55:36- Taraxacum.- Dandelion.
0:55:36 > 0:55:37- And this one?- Could be anything.
0:55:37 > 0:55:41Well, guess. We haven't got time to be 100% certain.
0:55:41 > 0:55:43- Typha angustifolia?- In English!
0:55:43 > 0:55:45Bulrushes.
0:55:45 > 0:55:48Well, Nicole did say that Beth had a job in a cafe on the river.
0:55:56 > 0:55:57HEART THUMPS SLOWLY
0:56:27 > 0:56:30INDISTINCT CHATTER ON POLICE RADIO
0:56:31 > 0:56:33SIREN WAILS IN DISTANCE
0:56:41 > 0:56:45'The paths we take sometimes lead us away from people we know and love.
0:56:49 > 0:56:54'But in the end, what matters is that we affect the lives of others for the better somehow -
0:56:54 > 0:56:58'whoever we are, whatever our story.
0:57:14 > 0:57:19'Obsession always destroys what it intended to nurture.
0:57:19 > 0:57:24'But if you're able to let yourself love honestly and without fear,
0:57:24 > 0:57:29'then maybe that huge heart you have will somehow set you free.'
0:57:36 > 0:57:39'We pretty much know who this is. Or rather was.'
0:57:39 > 0:57:40- Richard Warner.- The barrister?
0:57:40 > 0:57:42He was a human rights lawyer.
0:57:42 > 0:57:44- I'm not going to invest another penny.- Thanks, Dad.
0:57:44 > 0:57:46- Thanks for believing in me(!) - Anything else you're not telling me?
0:57:46 > 0:57:47Anything else I don't need to know?
0:57:47 > 0:57:48You need to catch this guy!
0:57:48 > 0:57:50- I know you, Mr Warner. - Police! Don't move!
