0:00:02 > 0:00:04There's been a murder. And we need you to solve it.
0:00:04 > 0:00:07Welcome to the TV show with only one question -
0:00:07 > 0:00:08whodunnit?
0:00:23 > 0:00:25Welcome to Armchair Detectives.
0:00:25 > 0:00:30The show where these 15 murder mystery enthusiasts will try and solve a
0:00:30 > 0:00:33deadly crime by the end of today's programme.
0:00:33 > 0:00:37Our amateur sleuths are placed at the centre of a fictional investigation
0:00:37 > 0:00:42set in Mortcliff, a sleepy village with a serious homicide problem.
0:00:42 > 0:00:46They'll watch the drama play out as Mortcliff's top police force
0:00:46 > 0:00:48spring into action. There they are.
0:00:48 > 0:00:50What a calendar that would be.
0:00:50 > 0:00:54DI Knight, DC Slater, and their scene of crime officer, Simmonds.
0:00:54 > 0:00:56We'll be heading to Mortcliff shortly.
0:00:56 > 0:00:59But first, let's meet our armchair detectives.
0:00:59 > 0:01:01- Hello, everyone.- Hello!
0:01:01 > 0:01:02Welcome back.
0:01:02 > 0:01:06Only three of you play each day, take your armchairs, please -
0:01:06 > 0:01:08Ellouise, Dipak and Audrey.
0:01:08 > 0:01:09Come on up.
0:01:13 > 0:01:15What a gentleman!
0:01:16 > 0:01:17Ellouise, welcome.
0:01:17 > 0:01:20- Hello.- What is going to make you a good armchair detective?
0:01:20 > 0:01:23I'm quite a curious person.
0:01:23 > 0:01:25I always like to know what everyone is up to.
0:01:25 > 0:01:26What everyone's doing.
0:01:26 > 0:01:28Dipak, welcome, what about you,
0:01:28 > 0:01:30what is going to make you a good armchair detective?
0:01:30 > 0:01:32A few years back I did a, kind of,
0:01:32 > 0:01:34management course where we were stuck out in the middle of Wales,
0:01:34 > 0:01:39and we had a two-day event where we had to go and chase some clues.
0:01:39 > 0:01:41Interrogate people, be interrogated.
0:01:41 > 0:01:43There's none of that today.
0:01:43 > 0:01:46Audrey, what's going to make you a good armchair detective?
0:01:46 > 0:01:50I'm always a bit suspicious of people if they are a bit too nice,
0:01:50 > 0:01:52I think...
0:01:52 > 0:01:56I think I'd slip quite nicely into the role.
0:01:56 > 0:01:59Well, the armchair detectives who correctly guess the killer will each get
0:01:59 > 0:02:05their hands on one of these, our very own golden magnifying glass trophy.
0:02:05 > 0:02:06- ALL:- Ooh!
0:02:06 > 0:02:10I'll be trying to solve the crime with you as we go along, too.
0:02:10 > 0:02:13So, it's time for round one.
0:02:13 > 0:02:16The crime scene. In today's story, Patently Murder,
0:02:16 > 0:02:18Knight and Slater meet Simmonds,
0:02:18 > 0:02:22who tells them all they need to know about today's victim.
0:02:22 > 0:02:25Note pads at the ready for the first time today,
0:02:25 > 0:02:27let's head over to Mortcliff.
0:02:37 > 0:02:40I've always wanted to call myself one of those, sir.
0:02:40 > 0:02:42You're too young for nostalgia, Slater.
0:02:42 > 0:02:45The Hells Angels are old enough to be your grandfather.
0:02:45 > 0:02:48You're always chipper early in the morning, Simmonds,
0:02:48 > 0:02:50- how do you manage it?- Plenty of coffee...
0:02:50 > 0:02:51and no social life.
0:02:51 > 0:02:53I can identify with one of those.
0:02:53 > 0:02:54It's not the coffee.
0:02:56 > 0:02:59Before I get done for bullying in the workplace, Simmonds,
0:02:59 > 0:03:01you'd better show us the scene.
0:03:01 > 0:03:04Yeah, save a DC's life, Simmonds.
0:03:04 > 0:03:06Don't give up your day job for a future in stand-up, Slater.
0:03:06 > 0:03:08I'm the funniest man I know.
0:03:10 > 0:03:11Right.
0:03:11 > 0:03:15Heather Cookham, the secretary at the factory, called for an ambulance
0:03:15 > 0:03:18at nine o'clock last night when she discovered this van had its engine
0:03:18 > 0:03:24running, with a pipe that ran from its exhaust, into this workshop.
0:03:24 > 0:03:27David Cotley, the victim, was in the building.
0:03:27 > 0:03:29He was alive when the medics arrived,
0:03:29 > 0:03:32but died later at hospital from carbon monoxide poisoning.
0:03:32 > 0:03:34Is it safe to go inside yet?
0:03:34 > 0:03:36Yeah. It's been thoroughly aired.
0:03:36 > 0:03:38We've done a prelim search and dust.
0:03:40 > 0:03:41Shall we?
0:03:45 > 0:03:48The place is a bit of a mess, but there are a few things of interest.
0:03:50 > 0:03:54We found this letter on one of the desks, as well as some paperwork.
0:03:56 > 0:03:59Also, this handkerchief with the letters PH on it.
0:04:02 > 0:04:04We're about to bag this, and test its contents.
0:04:04 > 0:04:09But as it was found near to where David was,
0:04:09 > 0:04:11we're surmising he was sick in it.
0:04:11 > 0:04:13From the carbon monoxide?
0:04:13 > 0:04:14That's the current assumption.
0:04:14 > 0:04:16This might be of interest.
0:04:16 > 0:04:18It's full of shredded documents.
0:04:18 > 0:04:20It was still warm when we arrived,
0:04:20 > 0:04:24so it looks like it was used just before David died.
0:04:24 > 0:04:26Any results on the van?
0:04:26 > 0:04:27Obviously, we'll do a full dust.
0:04:27 > 0:04:32But as it is a company vehicle, it's going to be overflowing with prints.
0:04:33 > 0:04:34OK.
0:04:34 > 0:04:37Let's find out who was here yesterday evening,
0:04:37 > 0:04:39and interview anyone of interest.
0:04:39 > 0:04:42- Already on it, sir.- Quite the double act!
0:04:44 > 0:04:48Well, Simmonds says she has no social life,
0:04:48 > 0:04:50I don't believe that for a second!
0:04:50 > 0:04:53So that is the initial crime scene.
0:04:53 > 0:04:55Audrey, let me start with you.
0:04:55 > 0:04:58The paper shredder being warm, obviously,
0:04:58 > 0:05:01has the victim shredded some paper he wanted to hide?
0:05:01 > 0:05:04Or did the killer shred something that he didn't want found?
0:05:04 > 0:05:07How does somebody who is trapped, and not get out of it,
0:05:07 > 0:05:11see that the gas was coming from the vehicle outside?
0:05:11 > 0:05:14Potentially somebody who is in there, and can't get out,
0:05:14 > 0:05:16yet they might have vomited, which is the victim's vomit,
0:05:16 > 0:05:19- if I heard correctly?- It's got to be planned,
0:05:19 > 0:05:23because it's had to be done at a certain time, for no-one to be around.
0:05:23 > 0:05:25To save them, stop them.
0:05:25 > 0:05:27And I want to know who PH is.
0:05:27 > 0:05:29Where did you see that?
0:05:29 > 0:05:31- The initials?- On the handkerchief.
0:05:31 > 0:05:33The handkerchief, yeah.
0:05:33 > 0:05:36Today, we are investigating the death of David Cotley,
0:05:46 > 0:05:49David and his friends call themselves the Petrolheads,
0:05:49 > 0:05:52a bunch of car engine enthusiasts.
0:06:00 > 0:06:02So that's our victim.
0:06:02 > 0:06:05Any early thoughts on him?
0:06:05 > 0:06:06Well, he's an inventor,
0:06:06 > 0:06:12could he have invented something that would be relevant, financially,
0:06:12 > 0:06:13to somebody else?
0:06:13 > 0:06:18Or to himself? Maybe that's why they've destroyed the paperwork.
0:06:18 > 0:06:24Interesting. So, the suspect list so far is pretty narrow.
0:06:24 > 0:06:28Heather Cookham, secretary at the Cotley Motor Factory.
0:06:28 > 0:06:30Although we haven't met Heather yet.
0:06:30 > 0:06:32She's the one who phoned the police.
0:06:32 > 0:06:34She is the secretary, any initial thoughts.
0:06:34 > 0:06:40I think the timing, for a secretary to work that late...
0:06:40 > 0:06:43To say his time of death was 11 o'clock at night.
0:06:43 > 0:06:46- So...- Do you know, I paid my way through university by being a secretary,
0:06:46 > 0:06:49Ellouise, and I was out that door at five o'clock!
0:06:49 > 0:06:52Every single night, I'll tell you that for nothing.
0:06:52 > 0:06:56In each round, you'll get to interrogate a piece of evidence more closely.
0:06:56 > 0:06:57So here is your first one.
0:06:57 > 0:07:03The forensic report detailing text messages found on David's phone.
0:07:03 > 0:07:06One from Simon, Tuesday 11:30am.
0:07:12 > 0:07:15And then to David Cotley again from Simon.
0:07:15 > 0:07:16Wednesday 10.15.
0:07:23 > 0:07:28Obviously, the PH on the hanky could have stood for "petrol heads".
0:07:28 > 0:07:32So that could be a company thing, the hanky.
0:07:32 > 0:07:34Ellouise is now desperately disappointed.
0:07:34 > 0:07:39She was hoping for the old trope of dropping the piece of evidence
0:07:39 > 0:07:40with the murderer's name!
0:07:40 > 0:07:42That would be really easy, wouldn't it!
0:07:42 > 0:07:44What did you say, though, Ellouise, about Simon?
0:07:44 > 0:07:47It's his son. It could be, he says, "Hey, Pops."
0:07:47 > 0:07:49Which is obviously...
0:07:49 > 0:07:51It could be, but who is the "we"?
0:07:51 > 0:07:54That's my question. Simon didn't make it,
0:07:54 > 0:07:56but did the person he was coming with make it?
0:07:56 > 0:08:00Some good thoughts there, but it's time for round two.
0:08:00 > 0:08:01Last movements.
0:08:01 > 0:08:07We'll get to see Petrolhead David Cotley, the day before his murder.
0:08:07 > 0:08:10Notepads at the ready. Let's head back to David's workshop.
0:08:22 > 0:08:25KNOCKING
0:08:39 > 0:08:41David!
0:08:49 > 0:08:51Oh, heavens above, don't do that!
0:08:51 > 0:08:54Sorry, sorry! You were away with the fairies.
0:08:54 > 0:08:56The inventive fairies.
0:08:56 > 0:08:59Simon. How are you doing, old chum?
0:08:59 > 0:09:01Sorry about the intrusion.
0:09:01 > 0:09:04After last week's meeting, you said I could pop round and chat.
0:09:04 > 0:09:07Right, yes.
0:09:07 > 0:09:08Delighted to chat.
0:09:08 > 0:09:10You're always welcome, Simon.
0:09:11 > 0:09:13Pull up a pew.
0:09:13 > 0:09:16- Thanks.- Get rid of that stuff.
0:09:22 > 0:09:24You...
0:09:24 > 0:09:27Get to air the workshop much?
0:09:27 > 0:09:30No need, old chap, I can't smell a thing.
0:09:30 > 0:09:33Hangover from that bad virus I got a few years ago.
0:09:41 > 0:09:42Well...?
0:09:43 > 0:09:45How long did the engine coil take to develop?
0:09:47 > 0:09:49About five years.
0:09:49 > 0:09:52I came up with a good many different prototypes to try and solve the
0:09:52 > 0:09:58issue. Not just me. Tony... your father, of course.
0:09:58 > 0:10:01To be honest, Tony was the one that came up with the original idea.
0:10:01 > 0:10:03Simon helped.
0:10:03 > 0:10:06I was the one who worked out how to engineer it.
0:10:06 > 0:10:08The original Petrolheads.
0:10:09 > 0:10:12Indeed. Named not for our driving skills,
0:10:12 > 0:10:16but for our collective obsession with machines.
0:10:16 > 0:10:18How did it make you rich?
0:10:18 > 0:10:21I patented the idea.
0:10:21 > 0:10:26And since I had a monopoly on the market, it made me very wealthy.
0:10:27 > 0:10:30As an inventor, it's important to understand the patent process.
0:10:32 > 0:10:36Well, generally, a patent lasts for 20 years,
0:10:36 > 0:10:40and you have to renew it every year within that time.
0:10:40 > 0:10:44I've got one idea here that's very nearly ready to go.
0:10:45 > 0:10:48You've always been an inspiration to me, old man.
0:10:48 > 0:10:51More of a father figure to me than Dad.
0:10:51 > 0:10:53Nonsense.
0:10:53 > 0:10:55Dad has a business proposal that may interest you.
0:10:55 > 0:10:58I've played a small part in the thinking.
0:10:58 > 0:11:01Would you be able to meet him at ten, tomorrow, in the evening?
0:11:04 > 0:11:08That sounds fine. You're a lot more interested in engineering than
0:11:08 > 0:11:10- Graham.- Well, unfortunately,
0:11:10 > 0:11:12we don't always inherit our parents' talents.
0:11:12 > 0:11:14I'm just lucky that I did.
0:11:15 > 0:11:17Great to chat.
0:11:17 > 0:11:20Tony! Hello!
0:11:20 > 0:11:23Hello. Hello, Dave. Si!
0:11:23 > 0:11:26- Am I interrupting?- Not at all, I was just about to leave.
0:11:26 > 0:11:28Thanks again, David.
0:11:31 > 0:11:35- Tony, good to see you out and about. - Always good to see you.
0:11:35 > 0:11:36Thanks for seeing me, David.
0:11:36 > 0:11:40Do you know, I fairly rattle around that great big house, you know.
0:11:41 > 0:11:45I thought you were going to downsize.
0:11:45 > 0:11:46June won't hear of it.
0:11:48 > 0:11:51She loves the grand life, our June, eh?
0:11:51 > 0:11:53Well, she helped with the patent, with the coil,
0:11:53 > 0:11:57so I suppose it's only fair that she can share in its spoils.
0:12:00 > 0:12:03Which is why I wanted to chat to you about the patent.
0:12:04 > 0:12:06I was hoping you'd consider changing your mind.
0:12:09 > 0:12:12Lots happened in that film, didn't it?
0:12:12 > 0:12:14So, I worked out who "we" was.
0:12:14 > 0:12:17- Yes, who's we?- David said,
0:12:17 > 0:12:20the original Petrolheads were Tony, Simon and David.
0:12:20 > 0:12:24And I presumed Simon was that Simon's dad.
0:12:24 > 0:12:28So then thought "we" was Simon and Simon.
0:12:28 > 0:12:31Then he said Graham, and I don't know who Graham is.
0:12:31 > 0:12:35It's almost like we've created a complex mystery for you to solve.
0:12:35 > 0:12:39Something stuck out for me at the start of that film.
0:12:39 > 0:12:40Did anyone else spot it?
0:12:40 > 0:12:42He was taking pictures of his own patent.
0:12:42 > 0:12:45- I did notice that.- That was his redesign, so at some point...
0:12:45 > 0:12:48- He's going to alter it.- ..I hope we get hold of that camera.
0:12:48 > 0:12:50Let's take another look at the suspects board.
0:12:50 > 0:12:54We still haven't met the mysterious Heather Cookham,
0:12:54 > 0:12:56the secretary at the Cotley Motor Factory.
0:12:56 > 0:12:58But there are four new suspects to add.
0:12:58 > 0:13:02We've got Simon Delaney, entrepreneur.
0:13:02 > 0:13:07Tony Harrow, Petrolhead member, and June Harrow, who is Tony's wife,
0:13:07 > 0:13:09who we haven't met yet.
0:13:09 > 0:13:13And Graham Cotley, who is David's son.
0:13:13 > 0:13:14What? Simon's dad?
0:13:14 > 0:13:15Because that says Simon Junior.
0:13:15 > 0:13:19June and Tony have obviously got some axe to grind about the patent.
0:13:19 > 0:13:23They were involved, or he said, how they were involved in the patent,
0:13:23 > 0:13:26and they wanted him to have a change of mind.
0:13:26 > 0:13:29Right. I've given you a piece of evidence already,
0:13:29 > 0:13:32now's your chance to pick another one from the following list.
0:13:32 > 0:13:35Decide as a group which one you fancy.
0:13:35 > 0:13:38We have a blank envelope found at the crime scene...
0:13:40 > 0:13:43or the patent agreement of the engine coil,
0:13:43 > 0:13:48and finally the forensic report on the van parked outside the workshop.
0:13:48 > 0:13:51I don't know why, but I'm drawn to blank envelope.
0:13:51 > 0:13:54I'm drawn to the van, because the patented agreement,
0:13:54 > 0:13:57all it's going to say is that it's for 20 years and renewable every year.
0:13:57 > 0:13:59Dipak, what do you...? You've got the casting vote here.
0:13:59 > 0:14:01Do you know what, I'm going to go blank envelope,
0:14:01 > 0:14:03- because it's something completely new.- Sorry.
0:14:03 > 0:14:05- That's all right.- We can look at the van in a bit.
0:14:05 > 0:14:07Let me reveal what the blank envelope says.
0:14:07 > 0:14:10The envelope is blank, and has a first-class stamp on it.
0:14:10 > 0:14:15Underneath the stamp is a camera memory card
0:14:15 > 0:14:18that has blueprint images saved on it.
0:14:18 > 0:14:21There is a hand-written letter found inside the envelope that says
0:14:21 > 0:14:25"Let me live, I want to break free. Save me."
0:14:25 > 0:14:28You said he was taking photos.
0:14:28 > 0:14:31So he could have taken the memory stick out of the card,
0:14:31 > 0:14:34hidden it there when he realised he was being gassed and thought,
0:14:34 > 0:14:36how am I going to do this, because the killer's maybe going to search
0:14:36 > 0:14:39this van. Hide it under the stamp, and then shove that in.
0:14:39 > 0:14:45So, armchair detectives, it's time now to lock in your prime suspect.
0:14:45 > 0:14:48Who do you think is most likely to be the killer so far?
0:14:48 > 0:14:52I need you to write down a name in your detective's notepad.
0:14:52 > 0:14:55At home, join in as well, write down who you think it is.
0:14:55 > 0:15:00Is it Heather, Simon Junior, Tony, June, or Graham.
0:15:00 > 0:15:02Write it down now.
0:15:11 > 0:15:14Time's up. Put your notepads away.
0:15:14 > 0:15:17- Ellouise.- Simon Junior.
0:15:17 > 0:15:18Simon Junior? Why?
0:15:18 > 0:15:24He's asking a lot of the right questions in terms of the murder.
0:15:24 > 0:15:27Dipak, who is your prime suspect and why?
0:15:27 > 0:15:28- I'm going with June.- June?
0:15:28 > 0:15:32- Yes.- June? We don't even know what June looks like, Dipak!
0:15:32 > 0:15:34I don't trust her silhouette!
0:15:37 > 0:15:39- Audrey?- Simon Junior.
0:15:39 > 0:15:40Simon Junior. Why?
0:15:40 > 0:15:41He was a bit too nosy.
0:15:41 > 0:15:44What in the hell has it got to do with him about the patents,
0:15:44 > 0:15:47and how long they run for, etc, etc.
0:15:47 > 0:15:51He's got ulterior motives about the finance behind this patent.
0:15:51 > 0:15:53OK. Interesting.
0:15:53 > 0:15:56It's on to round three now, the police interviews.
0:15:56 > 0:15:58Now, you get a lot of information here,
0:15:58 > 0:16:01so pay attention to everything that's said.
0:16:01 > 0:16:05It is time to see Knight and Slater zone in on the people close to the
0:16:05 > 0:16:07victim, and pull them in for questioning.
0:16:07 > 0:16:09Notepads at the ready.
0:16:09 > 0:16:11It's off to Mortcliff police station.
0:16:22 > 0:16:25Simmons, what do you have for us?
0:16:25 > 0:16:27The victim shows no signs of trauma.
0:16:29 > 0:16:31What about the van?
0:16:31 > 0:16:32It had a petrol engine.
0:16:34 > 0:16:35- Is that important?- Well,
0:16:35 > 0:16:39petrol engines emit more carbon monoxide than diesels.
0:16:39 > 0:16:43David Cotley died quicker than he would have done in a diesel vehicle.
0:16:44 > 0:16:46And the results on prints?
0:16:46 > 0:16:49There were no usable prints on the keys,
0:16:49 > 0:16:52all of the fingerprints found around the van were from David Cotley,
0:16:52 > 0:16:53or company workers.
0:16:53 > 0:16:57And the only prints on the pipe leading to the warehouse were from
0:16:57 > 0:17:00- Heather Cookham.- So nothing, then?
0:17:00 > 0:17:03I'm trying my hardest.
0:17:03 > 0:17:04Thank you, Simmonds.
0:17:04 > 0:17:07You are a shining star in the otherwise cold, dark universe.
0:17:10 > 0:17:13- Funny, Slater?- Hilarious, sir.
0:17:17 > 0:17:20Why did you visit David the day before his murder?
0:17:20 > 0:17:23To ask him to reconsider keeping a patent active.
0:17:24 > 0:17:26Money is tight at the moment.
0:17:26 > 0:17:29I've just done major renovations. Without money from the patent,
0:17:29 > 0:17:32I'm not quite sure what we're going to do.
0:17:32 > 0:17:34- We?- My wife, June and I.
0:17:34 > 0:17:36What does your wife do for a living?
0:17:36 > 0:17:39She takes care of all domestic arrangements.
0:17:41 > 0:17:43June is a great wife and mother,
0:17:43 > 0:17:46but that's when she's not out spending all my money.
0:17:47 > 0:17:50Never give a woman a credit card, she just goes mad with it.
0:17:53 > 0:17:57Do you have any idea who stands to inherit David's patents?
0:17:59 > 0:18:02No, I don't. David, Simon, June and I all benefited.
0:18:04 > 0:18:07What were you doing last night?
0:18:07 > 0:18:10I was at home, and June was at Bridge club.
0:18:14 > 0:18:16Why did you visit David the day before his murder?
0:18:18 > 0:18:20I didn't.
0:18:20 > 0:18:23Then why did he receive a text message saying you were visiting him?
0:18:25 > 0:18:27That was my son, Simon Junior.
0:18:27 > 0:18:29They've been close since Simon was a kid.
0:18:29 > 0:18:32He asked David if he would be able to meet us at ten that evening.
0:18:34 > 0:18:35If only we hadn't...
0:18:36 > 0:18:37..maybe he'd still be alive.
0:18:39 > 0:18:40Odd time for a business meeting?
0:18:41 > 0:18:43I had a busy day.
0:18:43 > 0:18:46Besides, we often caught up with one another in the evening.
0:18:47 > 0:18:49And what did you want to meet David about?
0:18:50 > 0:18:52I wanted to buy a patent off him.
0:18:55 > 0:18:56What is it that you do?
0:18:56 > 0:18:58I also construct engine parts.
0:19:00 > 0:19:02So you and David are partners?
0:19:02 > 0:19:04Well, no.
0:19:04 > 0:19:07Rivals would be more accurate.
0:19:07 > 0:19:08Don't get me wrong, David was a brilliant man,
0:19:08 > 0:19:10he just wasn't the only one around.
0:19:10 > 0:19:14I once patented a more modern idea than his at one point.
0:19:15 > 0:19:19Do you have any idea who stands to inherit the financial proceeds of
0:19:19 > 0:19:22- David's patents?- David loved Graham,
0:19:22 > 0:19:26I'd be surprised if he didn't pass on all his patents to his only son.
0:19:29 > 0:19:31What were you up to last night?
0:19:31 > 0:19:33I was at home. All evening.
0:19:34 > 0:19:38- With your son?- No, my son was at a friend's house.
0:19:40 > 0:19:43- Which friend?- I have no idea.
0:19:43 > 0:19:44He's a grown man.
0:19:45 > 0:19:49You'd have to ask him.
0:19:50 > 0:19:53- Well...- I noticed that he had a pocket hanky.
0:19:53 > 0:19:56You're still thinking about that hanky, aren't you?
0:19:56 > 0:19:57With PH on it.
0:19:57 > 0:20:00He was an original PH member, so...
0:20:00 > 0:20:02You're quite confrontational there, Ellouise.
0:20:02 > 0:20:04I'm just trying to help you.
0:20:04 > 0:20:05Audrey, what are you thinking?
0:20:05 > 0:20:09Simon Senior, right, strange time to have a meeting, ten o'clock at night.
0:20:09 > 0:20:12- It is.- His son was supposed to go with him, but didn't go,
0:20:12 > 0:20:14he went with friends.
0:20:14 > 0:20:15So he hasn't got an alibi.
0:20:15 > 0:20:19So if the son's not got an alibi, there's nobody to alibi the father.
0:20:19 > 0:20:21Absolutely. We've learned a lot.
0:20:21 > 0:20:23Let's take a look at the suspects.
0:20:23 > 0:20:27We're still waiting to meet the mysterious Heather Cookham.
0:20:27 > 0:20:32Who is she? And we've got a new one, Simon Delaney Senior.
0:20:32 > 0:20:35Who's a Petrolhead member, which means, previously,
0:20:35 > 0:20:38we met Simon Delaney Junior, the inventor.
0:20:38 > 0:20:43Along with Tony Harrow, Petrolhead member, June Harrow, Tony's wife,
0:20:43 > 0:20:47who we still haven't met, and Graham Cotley, David's son.
0:20:47 > 0:20:49Who we've also not met.
0:20:49 > 0:20:53Where is your finger of suspicion pointing now, Dipak?
0:20:53 > 0:20:55- I'm sticking with June.- Yeah?
0:20:55 > 0:20:57Yeah.
0:20:57 > 0:21:01- Audrey?- I'm joint between both Simon Delaneys.
0:21:01 > 0:21:04There's something a bit iffy about the pair of them.
0:21:04 > 0:21:06- Ellouise?- For some reason,
0:21:06 > 0:21:10Tony saying June was at Bridge club at the time of the murder isn't
0:21:10 > 0:21:13- sitting well.- Once again, you can pick a piece of evidence,
0:21:13 > 0:21:16and we've added a new one to the list.
0:21:16 > 0:21:20We now have the patented agreement of the engine coil,
0:21:20 > 0:21:24the forensics report on the van parked outside the workshop.
0:21:24 > 0:21:25Or this new piece of evidence,
0:21:25 > 0:21:29the forensics report on the pipe found at the workshop.
0:21:29 > 0:21:31Maybe the patent agreement gives us something.
0:21:31 > 0:21:35Yes, I think the patent agreement,
0:21:35 > 0:21:37because that holds a lot of clues to what's gone on here.
0:21:37 > 0:21:40If we're looking for a motive, I'd say the patent.
0:21:40 > 0:21:43Yeah. I definitely think there's something more in that pipe as well,
0:21:43 > 0:21:46because it's the only unique piece of evidence that's not contaminated,
0:21:46 > 0:21:47like the van, with other people using it.
0:21:47 > 0:21:49Shall we take the patent first?
0:21:49 > 0:21:51And then the next time, we can go for the pipe.
0:21:51 > 0:21:55Because technically, that's the murder weapon, if they pumped it in there.
0:21:55 > 0:21:58Yeah, but then I think the motive for the murder is in the patent
0:21:58 > 0:22:00agreement. We'll go for the pipe next, shall we?
0:22:00 > 0:22:02Let's go motive, then.
0:22:02 > 0:22:05I feel like Dipak has been slightly steam-rollered by Audrey there.
0:22:05 > 0:22:09So this is David's patent agreement that was found in his workshop.
0:22:09 > 0:22:13There's five years left on the agreement, with Tony and Simon both receiving
0:22:13 > 0:22:1715% total profit of the coil.
0:22:17 > 0:22:21Cotley, the victim, gets 70% of the profits.
0:22:21 > 0:22:24I think Cotley owns 70% of it,
0:22:24 > 0:22:30the other 30% he's gifted Simon Delaney Senior and Tony Harrow.
0:22:30 > 0:22:32They don't actually own it.
0:22:32 > 0:22:35- Otherwise they'd have...- I don't have any doubt about the ownership.
0:22:35 > 0:22:39He's written into the contract that these people will get a percentage share.
0:22:39 > 0:22:41But there's only five years left on the contract.
0:22:41 > 0:22:45So Tony would benefit from it being reapplied and extended,
0:22:45 > 0:22:48and Simon would benefit from it not being extended,
0:22:48 > 0:22:51because he would get to nick that engine part.
0:22:51 > 0:22:52Armchair detectives,
0:22:52 > 0:22:56I need you to write down who your prime suspect is now.
0:22:58 > 0:22:59Join in at home.
0:22:59 > 0:23:01Have you changed your mind?
0:23:05 > 0:23:07OK, let's see who you picked.
0:23:07 > 0:23:09Have you changed your mind or stuck with the same person?
0:23:09 > 0:23:13Ellouise, last time your prime suspect was Simon Junior.
0:23:13 > 0:23:14Have you changed your mind?
0:23:14 > 0:23:16- I have.- Who is it this time?
0:23:16 > 0:23:17Graham.
0:23:17 > 0:23:19Graham!
0:23:19 > 0:23:21Why have you picked someone we've not met?
0:23:21 > 0:23:23- That's the reason.- Because you've not met?
0:23:23 > 0:23:26- I don't know him.- I love it, Ellouise.
0:23:26 > 0:23:30- Dipak, last time you plumped for June.- Yes.
0:23:30 > 0:23:31Who we also hadn't met.
0:23:31 > 0:23:33We have you gone for this time?
0:23:33 > 0:23:35I've completely flipped now.
0:23:35 > 0:23:37- Simon Senior.- Simon Senior.
0:23:37 > 0:23:39- Why?- I'm just going on the evidence that we've got,
0:23:39 > 0:23:42who was most going to benefit from this patent,
0:23:42 > 0:23:46you know, changing hands, or defaulting.
0:23:46 > 0:23:48Audrey, last time you went for...
0:23:48 > 0:23:50- Simon Junior.- Simon Junior.
0:23:50 > 0:23:56- I'm sticking with Simon Junior.- Oh, really?- Yes. There's just something not right about him.
0:23:56 > 0:23:59He's a bit too slippery.
0:23:59 > 0:24:04Slippery! Well, now it's time for round four, where we dig a bit deeper.
0:24:04 > 0:24:07It's one week before David Cotley's death,
0:24:07 > 0:24:09and let's head back to Mortcliff.
0:24:16 > 0:24:19Excellent. Nectar of the gods.
0:24:19 > 0:24:22You really need a clear-out in here.
0:24:22 > 0:24:24Nonsense, this workshop is self-cleaning.
0:24:27 > 0:24:29Well, let me open a window for some fresh air.
0:24:29 > 0:24:32Oh, wait, the window doesn't work!
0:24:32 > 0:24:34Give the man a break, Heather!
0:24:34 > 0:24:36I agree with her, this place is a tip.
0:24:36 > 0:24:38I'm the only one that works here,
0:24:38 > 0:24:41so you can leave it exactly the way it is, thank you very much, Heather.
0:24:43 > 0:24:49Friends, we have worked together off and on, over the years,
0:24:49 > 0:24:55and ever since the engine timing coil was patented 15 years ago,
0:24:55 > 0:24:58we have done very nicely for ourselves.
0:24:58 > 0:25:01DOOR SLAMS
0:25:01 > 0:25:03Sorry we're late. Bus delays.
0:25:05 > 0:25:07Very nice indeed.
0:25:08 > 0:25:09New perfume?
0:25:09 > 0:25:11I wear this every day.
0:25:11 > 0:25:14If you had, I would surely have noticed.
0:25:14 > 0:25:17I smell nothing. Which is just as well,
0:25:17 > 0:25:20because you know that perfume is nothing more than ethanol.
0:25:20 > 0:25:22Try not to spoil the moment, eh, Dad?
0:25:24 > 0:25:30Anyway. I was just about to say that I have decided that now is the right
0:25:30 > 0:25:32time for me to retire.
0:25:33 > 0:25:34Already?
0:25:36 > 0:25:38Indeed, you're a spring chicken.
0:25:39 > 0:25:41Retirement's not all it's cut out to be, David.
0:25:41 > 0:25:43I'm getting on in years
0:25:44 > 0:25:48and I'm able to live comfortably.
0:25:48 > 0:25:52What with my latest patent almost ready to be sent off
0:25:52 > 0:25:59and the timing coil patent about to expire for the year, it just seems the right time.
0:25:59 > 0:26:01And what will happen to the patent?
0:26:02 > 0:26:05We're still making £200,000 a year on it.
0:26:05 > 0:26:09But that's already dropped by half over the last decade.
0:26:10 > 0:26:14Although there's still five years left, I'm going to let the patent drop.
0:26:21 > 0:26:23- Wow!- I know.
0:26:23 > 0:26:25There were lots of looks there, weren't there.
0:26:25 > 0:26:26Yes.
0:26:29 > 0:26:30What do you think, Dipak?
0:26:30 > 0:26:36Mr and Mrs Harrow, if he retires, or he dies, they lose out,
0:26:36 > 0:26:37because the patent doesn't get renewed.
0:26:37 > 0:26:39He owns the patent.
0:26:39 > 0:26:43The secretary also, if he retires, she's got no job,
0:26:43 > 0:26:46and she needs him to hang around, maybe.
0:26:46 > 0:26:48So, let's take a look at the suspects board.
0:26:48 > 0:26:52So, finally we can put faces to the names of Heather Cookham,
0:26:52 > 0:26:57the secretary at the Cotley motor factory, and June Harrow, Tony's wife.
0:26:57 > 0:27:00We've also of course got Simon Delaney Senior,
0:27:01 > 0:27:03Simon Delaney Junior,
0:27:04 > 0:27:10Tony Harrow and finally as well, Graham Cotley, who was the victim's son.
0:27:10 > 0:27:12Anything changed for you?
0:27:12 > 0:27:13No.
0:27:13 > 0:27:15No. Ellouise?
0:27:20 > 0:27:22Well, Ellouise, you'll be delighted to hear, once again,
0:27:22 > 0:27:25it's time to pick your evidence.
0:27:25 > 0:27:27There's another new item on the list.
0:27:27 > 0:27:30You can either have the forensics report on the van parked outside the
0:27:30 > 0:27:34workshop. The forensics report on the pipe found at the workshop,
0:27:34 > 0:27:38and the new item of evidence is the last will and testament
0:27:38 > 0:27:39of David Cotley.
0:27:39 > 0:27:42The decision is yours, guys, what do you want to see?
0:27:42 > 0:27:45Since Ellouise and I got our way the last time,
0:27:45 > 0:27:46we'll let you have your way this time.
0:27:46 > 0:27:50Oh, my God, I'm going to marry both of you, this sounds amazing.
0:27:50 > 0:27:56So, in a beautiful example of consensus, Dipak, you now get your choice,
0:27:56 > 0:27:59and you want to see the forensics on the pipe.
0:27:59 > 0:28:03The forensic report reveals fingerprints were found on the middle of the
0:28:03 > 0:28:07pipe, and silk fibres found at the ends of the pipe,
0:28:07 > 0:28:12the fingerprints belonging to Heather Cookham.
0:28:12 > 0:28:16- Ellouise?- I'm really trying to remember who was wearing a scarf.
0:28:16 > 0:28:22I don't know if it was Heather and June, or just June.
0:28:22 > 0:28:27The secretary, to me, doesn't look like the silk scarf type of lady.
0:28:27 > 0:28:29But June, with her lavish lifestyle...
0:28:29 > 0:28:31June would have that, yes.
0:28:31 > 0:28:34Guys, it's time to pick your prime suspect again.
0:28:34 > 0:28:36Armchair detectives...
0:28:36 > 0:28:38Write down who your prime suspect is now.
0:28:47 > 0:28:50Have you changed your mind, or stuck with the same person?
0:28:50 > 0:28:52Ellouise, last time you went for Graham Cotley,
0:28:52 > 0:28:53despite never having seen him.
0:28:53 > 0:28:55Who have you gone for this time?
0:28:55 > 0:28:57- June.- Why?
0:28:57 > 0:28:59I feel like she's the only one that can afford a silk scarf.
0:28:59 > 0:29:03Dipak, last time you went for
0:29:03 > 0:29:04Simon Senior.
0:29:04 > 0:29:07Have you stuck with that, or have you changed?
0:29:07 > 0:29:09I've stuck with Simon Senior.
0:29:09 > 0:29:12- Because?- Because I haven't got any other evidence to push me either way.
0:29:12 > 0:29:16I like the whole lavish lifestyle with the silk, the handkerchief,
0:29:16 > 0:29:19I'm still waiting to put a few key pieces together.
0:29:19 > 0:29:23Audrey, last time you went for Simon Junior.
0:29:23 > 0:29:24- Yes.- Have you changed your mind?
0:29:24 > 0:29:28No, I haven't. He's obviously got wind at that meeting that they had
0:29:28 > 0:29:31before that he had a new patent.
0:29:31 > 0:29:34So I think he's maybe trying to get his grubby, greasy little paws on it.
0:29:34 > 0:29:40Right. Well, we're motoring towards closing this case, it's round five.
0:29:40 > 0:29:42The final clues.
0:29:42 > 0:29:46The detectives go to meet Graham, David's son,
0:29:46 > 0:29:48so let's have a look and see what happens.
0:29:54 > 0:29:55Nice.
0:29:56 > 0:29:59Hearing the call of the road, are you, Slater?
0:30:00 > 0:30:01Something like that.
0:30:12 > 0:30:14Thank you.
0:30:15 > 0:30:17Just through here.
0:30:17 > 0:30:20Is that your bike outside?
0:30:20 > 0:30:22- Yeah.- Cool.
0:30:22 > 0:30:24More of a Stones man myself.
0:30:25 > 0:30:27Can I see your driving licence, please?
0:30:27 > 0:30:29Yeah.
0:30:33 > 0:30:36Category A only?
0:30:36 > 0:30:39Dad reckoned cars would be obsolete within 20 years, so...
0:30:41 > 0:30:44- Take a seat.- Thank you.
0:30:48 > 0:30:49Sorry to have to ask this,
0:30:49 > 0:30:53but do you know who benefits from your father's will?
0:30:56 > 0:30:57I think I do.
0:30:57 > 0:31:03The factory, and all of Dad's inventions go into a trust or something.
0:31:03 > 0:31:05He probably wouldn't leave it to me,
0:31:05 > 0:31:07I know he wanted me to take over the business,
0:31:07 > 0:31:09but it's not really something I want to do.
0:31:12 > 0:31:16Do you know what he was working on? We found a lot of shredded documents.
0:31:17 > 0:31:20I wish I'd known, but he was very secretive.
0:31:23 > 0:31:25Do you know Simon Delaney?
0:31:25 > 0:31:27Dad's known both the Delaneys for years.
0:31:27 > 0:31:30Simon Delaney would have loved to patent anything Dad developed.
0:31:32 > 0:31:35Was there any bad blood between them?
0:31:35 > 0:31:38Look, my dad was the sweetest man.
0:31:38 > 0:31:42I really don't know why anyone would want to kill him.
0:31:42 > 0:31:46Even though he could be infuriating and eccentric,
0:31:46 > 0:31:49and make bizarre choices, sometimes.
0:31:49 > 0:31:51What kind of bizarre choices?
0:31:52 > 0:31:55Well, the decision to drop his main patent, for example.
0:31:57 > 0:31:59That didn't make sense to you?
0:31:59 > 0:32:02He'd have made much more money if he'd kept it active.
0:32:10 > 0:32:12I didn't know David was around.
0:32:12 > 0:32:15I assumed he'd gone home at five as he usually does.
0:32:17 > 0:32:18You stayed late?
0:32:21 > 0:32:22I was going on holiday,
0:32:22 > 0:32:26and I wanted to sort out the salaries before I left.
0:32:30 > 0:32:32Did you see anyone else, or hear anything?
0:32:34 > 0:32:35No.
0:32:36 > 0:32:40It was around nine, I realised I could hear an engine running.
0:32:41 > 0:32:45That's when I saw the van parked outside the workshop.
0:32:45 > 0:32:47It struck me as odd.
0:32:47 > 0:32:48So I went to have a look.
0:32:49 > 0:32:52That's when I saw the pipe.
0:32:52 > 0:32:57I yanked the pipe from the workshop door, and the van,
0:32:57 > 0:33:01and then reversed the van from outside the workshop.
0:33:01 > 0:33:05When I opened the door, David was lying on the floor.
0:33:06 > 0:33:09The ambulance turned up pretty quickly.
0:33:12 > 0:33:13I can't believe he's dead.
0:33:15 > 0:33:17How long had you known David?
0:33:19 > 0:33:2025 years.
0:33:21 > 0:33:23He was such a generous man.
0:33:25 > 0:33:27Always. He was going to give me a pay rise
0:33:27 > 0:33:31once the latest patent had been filed.
0:33:33 > 0:33:35Where did you keep the keys to the van?
0:33:38 > 0:33:40Above the sun visor.
0:33:42 > 0:33:44David thought that was sensible?
0:33:45 > 0:33:47We kept them there for years.
0:33:47 > 0:33:50Because the van was widely used within the company.
0:33:52 > 0:33:55Thank you, Miss Cookham. That will be all for now.
0:33:59 > 0:34:01Well...
0:34:01 > 0:34:06One thing that was a bit strange, in the note that he left,
0:34:06 > 0:34:12- "Let me live, I want to break free. Save me".- Yes?
0:34:12 > 0:34:14The son had a poster up of Queen.
0:34:14 > 0:34:16One of their famous songs is I Want to Break Free.
0:34:16 > 0:34:19Oh, that got a round of applause, Audrey.
0:34:19 > 0:34:22That got a round of applause.
0:34:22 > 0:34:26So it's a bit strange that that should be in the thing.
0:34:26 > 0:34:29And the son says that the inventions go into a trust,
0:34:29 > 0:34:32but didn't say who the trust was for.
0:34:32 > 0:34:33But in some sort of trust.
0:34:33 > 0:34:36- Could it have been him?- Let me see if I can help you,
0:34:36 > 0:34:38- because you now get to pick your final piece of evidence.- Right.
0:34:38 > 0:34:42You've just got two pieces of evidence left to choose from.
0:34:42 > 0:34:46But you'll only see one of them before you make your final accusation.
0:34:46 > 0:34:50So you can have either the forensics report on the van parked outside the
0:34:50 > 0:34:55workshop, or you can have the last will and testament of David Cotley.
0:34:55 > 0:34:59Personally, I'll go for the will. What do you guys want to do?
0:34:59 > 0:35:01Let's see what the will has to say.
0:35:01 > 0:35:03- Will?- Yeah, will.
0:35:03 > 0:35:06OK. You've chosen to see the will of Mr David Cotley.
0:35:06 > 0:35:09So, David's last will and testament explains that everything will be
0:35:09 > 0:35:12passed onto his son, Graham, in the event of his death.
0:35:12 > 0:35:14But he didn't want it.
0:35:14 > 0:35:17He said very clearly, Dad knew that I didn't want it.
0:35:17 > 0:35:22- Yeah, a lie.- So would he then give himself it by killing his dad?
0:35:22 > 0:35:26There's also the new patent as well that was going to be pending.
0:35:26 > 0:35:30Patent number. That is the patent that he's getting.
0:35:30 > 0:35:31Does anyone remember the old patent number.
0:35:31 > 0:35:35Graham did say that his father wouldn't have left him that,
0:35:35 > 0:35:37and it was going to a trust.
0:35:37 > 0:35:39That was a porky pie.
0:35:39 > 0:35:42Well, armchair detectives, this is the big moment.
0:35:42 > 0:35:46You've seen most of the evidence, you've met all of the suspects.
0:35:46 > 0:35:50You're about to make your final accusation for the chance of winning that
0:35:50 > 0:35:53golden magnifying glass trophy.
0:35:53 > 0:35:58So, I need you to write down who you are accusing now.
0:35:58 > 0:36:01And you at home, who are you going to choose?
0:36:01 > 0:36:04Have you been paying attention?
0:36:04 > 0:36:08Who wears silk scarves, who owns the handkerchief?
0:36:08 > 0:36:10These and many more questions will never be answered...
0:36:10 > 0:36:13No! They will be answered in just a minute.
0:36:13 > 0:36:17Time's up. Please put your pads and pencils down, armchair detectives.
0:36:17 > 0:36:19Ellouise, who have you accused?
0:36:19 > 0:36:21Simon Senior.
0:36:21 > 0:36:23Simon Senior, and why?
0:36:23 > 0:36:26Just going back to his interview,
0:36:26 > 0:36:33I feel like he was very sketchy and he seems quite close to Heather to have
0:36:33 > 0:36:37all the secret information, and his son went and done all the digging.
0:36:39 > 0:36:42Dipak? Who have you accused?
0:36:42 > 0:36:44I've gone with Graham.
0:36:44 > 0:36:46- Cotley?- That's correct.- The son?
0:36:46 > 0:36:49The victim's son? And why?
0:36:49 > 0:36:54The very loose thread that I'm not convinced he wasn't aware of the will.
0:36:54 > 0:36:59- Audrey?- I changed my mind to young Graham,
0:36:59 > 0:37:03because the fact that he said he wasn't going to inherit anything,
0:37:03 > 0:37:05which he clearly was.
0:37:05 > 0:37:07Before Knight and Slater tell us whodunnit,
0:37:07 > 0:37:10there's one piece of evidence you haven't seen yet.
0:37:10 > 0:37:12Would it have made a difference?
0:37:12 > 0:37:13Would you have changed your minds?
0:37:13 > 0:37:16Let's take a look. What you didn't look at was the forensic report on
0:37:16 > 0:37:18the van.
0:37:18 > 0:37:21It's a white van that was parked outside the workshop.
0:37:21 > 0:37:25The vehicle has a dent in the left side, the front seat is forwards,
0:37:25 > 0:37:27and the keys have been left in the ignition.
0:37:27 > 0:37:31Fingerprint matches, David Cotley, Heather Cookham,
0:37:31 > 0:37:33and workers from the factory.
0:37:33 > 0:37:37Silk fibres were found throughout.
0:37:37 > 0:37:39Would that have changed your mind at all?
0:37:39 > 0:37:44No. The silk fibres throughout the interior,
0:37:44 > 0:37:46could have come from anybody, at any time.
0:37:46 > 0:37:50What really happened in today's story, Patently Murder?
0:37:50 > 0:37:53Who killed David Cotley?
0:37:53 > 0:37:55Let's find out. Whodunnit?
0:38:00 > 0:38:04The pipe could only have been pulled out by Heather, not inserted,
0:38:04 > 0:38:06as there were no fingerprints found near the exhaust.
0:38:06 > 0:38:10With David dead, Heather loses out on her job.
0:38:12 > 0:38:16Simon Delaney Junior and Senior both have other business interests.
0:38:16 > 0:38:20According to the Inland Revenue, they are doing very well indeed.
0:38:21 > 0:38:25Graham is the one who stands to gain most from his father's death.
0:38:27 > 0:38:31Graham has a Category A driving licence, can he drive a van, so...
0:38:34 > 0:38:37Whereas Tony and June Harrow on the other hand...
0:38:41 > 0:38:43- I think we should bring them in.- Mm.
0:38:49 > 0:38:53For the record, present are DI Knight and DC Slater,
0:38:53 > 0:38:55interviewing June Harrow.
0:38:55 > 0:38:58Mrs Harrow, thank you for coming in today.
0:38:58 > 0:39:00No problem.
0:39:00 > 0:39:03Where were you on the night of David Cotley's murder?
0:39:04 > 0:39:07I played bridge at my club.
0:39:07 > 0:39:10- Did you drive there? - Mm-hm, I always do.
0:39:14 > 0:39:16You're very smart, aren't you?
0:39:18 > 0:39:21It's a long time since I've been called that.
0:39:21 > 0:39:24Well, you left university with a double first in engineering.
0:39:25 > 0:39:31Your husband told us that the idea for David's electrical coil came from you.
0:39:32 > 0:39:36Yes... Not something David remembered!
0:39:36 > 0:39:37Must have been difficult.
0:39:37 > 0:39:40So talented, but overlooked because of your gender.
0:39:42 > 0:39:44I wasn't the only one.
0:39:44 > 0:39:49And then to add insult to injury, David decided to let the patent lapse.
0:39:50 > 0:39:53- It was outrageous.- Being overlooked is one thing,
0:39:53 > 0:39:58but losing money on something that was yours to begin with must
0:39:58 > 0:39:59have been the final insult.
0:40:01 > 0:40:04- I don't know what you mean.- You and your husband were struggling
0:40:04 > 0:40:05financially.
0:40:06 > 0:40:09Tony tried to persuade David to keep the patent active,
0:40:09 > 0:40:10to keep money coming in.
0:40:12 > 0:40:17Tony knew that David was meeting Simons Junior and Senior so, therefore,
0:40:17 > 0:40:18he would be in the workshop late.
0:40:20 > 0:40:24So you drove to the workshop, you knew where the van keys were kept.
0:40:24 > 0:40:27David didn't hear you, because he was listening to music.
0:40:27 > 0:40:30Nor did he notice the fumes from the van.
0:40:30 > 0:40:35See, you knew David had lost his sense of smell after a sinus infection.
0:40:35 > 0:40:37Once the pipe was in place,
0:40:37 > 0:40:40you parked the van in such a way as to block the workshop door,
0:40:40 > 0:40:43you then got into your own car and drove to bridge club.
0:40:45 > 0:40:47That's quite a story.
0:40:47 > 0:40:50David started to feel unwell.
0:40:50 > 0:40:52He noticed the pipe under the door.
0:40:52 > 0:40:57He tried to get out, but he couldn't, because the van was in the way.
0:40:57 > 0:40:58The window wouldn't open,
0:40:58 > 0:41:00you knew that too.
0:41:00 > 0:41:04By the time Heather called the ambulance, it was too late.
0:41:04 > 0:41:06The poison was already in his system.
0:41:06 > 0:41:10Something you failed to realise was that David had enough time to shred
0:41:10 > 0:41:14the blueprint. We found an envelope with quotes from Queen songs, no name,
0:41:14 > 0:41:17but both Graham and David were fans.
0:41:18 > 0:41:20You have no proof.
0:41:22 > 0:41:24You are the only one of the Petrolheads who can drive.
0:41:26 > 0:41:28Sorry we're late, bus delays.
0:41:29 > 0:41:33Also, you are, what, five-foot five?
0:41:33 > 0:41:37We noticed the driver's seat in the van was pushed quite far forward.
0:41:37 > 0:41:40Our forensic team have just finished tests on the seat adjuster.
0:41:40 > 0:41:44It had silk fibres on it.
0:41:44 > 0:41:47The same silk fibres that they found on the pipe.
0:41:48 > 0:41:52And I'm willing to bet my life that they match your scarf.
0:41:53 > 0:41:56You had motive, means and opportunity.
0:41:59 > 0:42:02It was my idea. Mine.
0:42:02 > 0:42:04He should have remembered where it came from
0:42:04 > 0:42:06and he shouldn't have let the patent lapse.
0:42:08 > 0:42:09He deserved to die.
0:42:12 > 0:42:15June Harrow, I'm arresting you for the murder of David Cotley.
0:42:19 > 0:42:22You picked up on all of the clues,
0:42:22 > 0:42:24you just didn't put it together.
0:42:24 > 0:42:31And at one point, June Harrow was identified by you,
0:42:31 > 0:42:33and you changed your mind.
0:42:33 > 0:42:35Does it all make sense now?
0:42:35 > 0:42:38- Yeah.- Yeah.- Because when I said hindsight, I wanted to go back to her,
0:42:38 > 0:42:41because I knew Category A licence, but it's all too late.
0:42:41 > 0:42:42My life is over!
0:42:43 > 0:42:48No, because the joy of Armchair Detectives is you get another chance.
0:42:48 > 0:42:50- Learn from our mistakes. - Don't worry.
0:42:50 > 0:42:52Never mind, guys. You failed to pick today's killer.
0:42:52 > 0:42:54Better luck next time.
0:42:54 > 0:42:56Did any of you pick the killer?
0:42:58 > 0:43:00Well, you get your chance as well.
0:43:00 > 0:43:03That's all from Armchair Detectives, come back tomorrow,
0:43:03 > 0:43:07where we find Knight and Slater on a cliff edge.
0:43:07 > 0:43:12And remember, no-one gets away with murder in Mortcliff.
0:43:12 > 0:43:14Goodbye.
