0:00:02 > 0:00:04Remember when all your school mates said they wanted to be an astronaut
0:00:04 > 0:00:07or a pop star and you said you wanted to be a police detective?

0:00:09 > 0:00:13Welcome to the TV show with only one question.
0:00:13 > 0:00:15Whodunnit?

0:01:25 > 0:01:27Welcome, Armchair Detectives.

0:01:35 > 0:01:37- AUDIENCE:- Ooh!
0:01:38 > 0:01:41Now, you've all played twice before.
0:01:41 > 0:01:44Kathryn and James have a 100% record.
0:01:44 > 0:01:47What's the secret to your success, do you think, James?
0:01:47 > 0:01:51I've got a really good eye for detail and I'm good at pic...
0:01:51 > 0:01:54piecing everything together, and I think that's...
0:01:54 > 0:01:56I don't want to mention my job too much
0:01:56 > 0:01:59because I want to keep it at the end of this, so if I get it wrong...
0:01:59 > 0:02:02I mean, you kind of have mentioned it so...you are.
0:02:02 > 0:02:04- You're a detective.- Yes.
0:02:04 > 0:02:07- Yes.- No, I am a detective!
0:02:07 > 0:02:09Kathryn, what's the secret to your success?
0:02:09 > 0:02:12When I was about 12
0:02:12 > 0:02:14I was given as a present
0:02:14 > 0:02:17a biography of a very famous pathologist,
0:02:17 > 0:02:19and I've been really interested in pathology
0:02:19 > 0:02:21- and forensic medicine since then. - Which pathologist was it?
0:02:21 > 0:02:23Sir Bernard Spilsbury.
0:02:23 > 0:02:25- I've read that one, it's very interesting indeed.- It's very good.
0:02:25 > 0:02:29- Absolutely. Now, Bola.- Hi.
0:02:29 > 0:02:30- You haven't won yet.- No.
0:02:30 > 0:02:32I can't tell you how much I want you
0:02:32 > 0:02:35to win a golden magnifying glass trophy today.
0:02:35 > 0:02:37Have you been psyching yourself up?
0:02:37 > 0:02:39Yeah. Definitely going to be taking my notes,
0:02:39 > 0:02:41but I'm not going to panic last minute as much as I did
0:02:41 > 0:02:42- the last two times.- Absolutely.
0:02:42 > 0:02:46Well, we're rooting for you, we're rooting for you -
0:02:46 > 0:02:48all of you Armchair Detectives, good luck.
0:02:48 > 0:02:51It's time for round one, the Crime Scene.
0:02:51 > 0:02:55Knight and Slater have been called into Mortcliff College,
0:02:55 > 0:02:58and it's not because a pupil handed their homework in late.
0:02:58 > 0:03:00Notepads at the ready -
0:03:00 > 0:03:04for the first time today, let's go to Mortcliff.
0:03:16 > 0:03:19Bring back memories, Slater?
0:03:19 > 0:03:22Yeah! I was a science luminary.
0:03:22 > 0:03:23You?
0:03:23 > 0:03:26Oh, my strongest subject was always poetry.
0:03:28 > 0:03:30There's nothing that explores the human condition
0:03:30 > 0:03:32quite like poetry, Slater.
0:03:32 > 0:03:34No, you're right, sorry, sir.
0:03:35 > 0:03:36Ah, Ms Webster, is it?
0:03:36 > 0:03:39- Yes, hello, detectives. - Hi.- Hi.
0:03:39 > 0:03:41How's Mr Roberts?
0:03:41 > 0:03:42Not too good, I'm afraid.
0:03:42 > 0:03:46Did you notice anything suspicious this morning?
0:03:46 > 0:03:48In fact, yeah. When I arrived,
0:03:48 > 0:03:52I thought I saw someone jumping out of a window around the south side,
0:03:52 > 0:03:55at least I think I did. I can't be too sure.
0:03:55 > 0:03:57It happened so quickly.
0:03:57 > 0:04:01Well, if you think of anything else, do give DC Slater a call.
0:04:01 > 0:04:03I can take you to the room just now.
0:04:03 > 0:04:04Thank you.
0:04:07 > 0:04:09Hi, anything so far?
0:04:09 > 0:04:11Seems like a heart attack. No other injuries.
0:04:11 > 0:04:13I'm not optimistic about prints,
0:04:13 > 0:04:16there's so many staff members come in and out of this room.
0:04:16 > 0:04:17Time of death?
0:04:17 > 0:04:19About 9.40 am.
0:04:19 > 0:04:23Victim is a Miss Emma Kean, 50 years old.
0:04:23 > 0:04:25She died during a fire drill.
0:04:25 > 0:04:28She came back in to get her register.
0:04:28 > 0:04:31The door was broken, so they had to force entry to get to her.
0:04:31 > 0:04:34She was found by a Mr Roberts.
0:04:34 > 0:04:36Who scheduled the drill?
0:04:36 > 0:04:38It wasn't a scheduled drill.
0:04:38 > 0:04:40I think you boys need to work out who raised the alarm.
0:04:40 > 0:04:41It's on my list, m'lady.
0:04:41 > 0:04:44Do you know where this Mr Roberts is?
0:04:44 > 0:04:45I think he's in the art room.
0:04:45 > 0:04:49Thanks, Simmons. We'll let you get on with your work.
0:04:49 > 0:04:51Yeah, thanks, Simmons. Get on with your work.
0:04:51 > 0:04:54I could hide your body and no-one would ever find it.
0:04:56 > 0:04:59Mr Roberts, I'm sorry for your loss.
0:05:01 > 0:05:03Do you feel able to answer some questions right now?
0:05:06 > 0:05:07Go ahead.
0:05:10 > 0:05:13Can you tell us what happened this morning?
0:05:16 > 0:05:17I...
0:05:19 > 0:05:24Yes. I arrived at about 8.30, normal time.
0:05:26 > 0:05:29Greeted pupils and teachers at the gate.
0:05:29 > 0:05:31Ms Kean arrived late.
0:05:34 > 0:05:36I was chatting in the staff room,
0:05:36 > 0:05:39and then the fire alarm went off,
0:05:39 > 0:05:41so I went outside to see what was happening,
0:05:41 > 0:05:45and carried out the evacuation procedure in the playground.
0:05:46 > 0:05:48And Ms Kean went back?
0:05:48 > 0:05:49She went back for the register.
0:05:51 > 0:05:53I went back inside with Mr Fawcett
0:05:53 > 0:05:56and opened the fire alarm cabinet
0:05:56 > 0:05:58and reset the alarm.
0:06:00 > 0:06:04I noticed the handle on the office door
0:06:04 > 0:06:06was off on both sides.
0:06:07 > 0:06:09I looked through the hole and...
0:06:13 > 0:06:14..and saw her.
0:06:18 > 0:06:19HE SOBS
0:06:27 > 0:06:30She'd just been voted Teacher of the Year.
0:06:33 > 0:06:35Why?!
0:06:38 > 0:06:40Luckily, we do have CCTV on the south side.
0:06:40 > 0:06:43I thought you may want to have a look at this.
0:06:46 > 0:06:50So it's about 9.30, that's when the fire alarm had already gone off.
0:06:50 > 0:06:53She climbs in, and five minutes later...
0:06:56 > 0:06:58..she climbs out the window, see?
0:06:58 > 0:07:01- Can we get a copy of this? - Yeah.
0:07:01 > 0:07:03Pity we can't see her face and what she's carrying.
0:07:03 > 0:07:06Oh, I can't tell you what, but I can tell you who.
0:07:11 > 0:07:14Oh-ho-ho-ho-ho, this is a good one.
0:07:14 > 0:07:16There's going to be a lot of suspects.
0:07:16 > 0:07:20- You think it'll be just a school photo?- Yes!
0:07:23 > 0:07:26Just give me the yearbook, that's fine, we'll work from that.
0:07:26 > 0:07:28What about what you've seen so far?
0:07:28 > 0:07:30So I think from where she was found
0:07:30 > 0:07:33there's possibly going to be quite a lot of DNA in there.
0:07:33 > 0:07:37- Yeah.- So we saw the brownies, didn't we? So..
0:07:37 > 0:07:39Yes, there was a... The camera lingered on the...
0:07:39 > 0:07:42- that plate of brownies. - Yes, the camera also lingered on
0:07:42 > 0:07:44- some coffee cups in the bin. - Yep.
0:07:44 > 0:07:47- And some coffee cups that were stacked up as well.- Yep.
0:07:47 > 0:07:50Suspected heart attack makes me think
0:07:50 > 0:07:53maybe we're going down the route of maybe a poisoning.
0:07:53 > 0:07:55- Could be, could be. - Something to raise the heart.
0:07:55 > 0:07:58Gemma Webster, wasn't it, that...
0:07:58 > 0:08:02She said she'd seen somebody jump out the window on the south side.
0:08:02 > 0:08:04Miss Webster, yep, mm-hmm.
0:08:04 > 0:08:08So I think that's been confirmed, hasn't it, by the CCTV?
0:08:08 > 0:08:11Yeah, Craig Thomas, yeah, Craig Thomas showed us the CCTV.
0:08:11 > 0:08:15- And on the CCTV he kept on referring to her as "she".- She. Yep.
0:08:15 > 0:08:18- She, and that she was carrying something.- Yep.
0:08:18 > 0:08:21He can't tell us what she was carrying...
0:08:21 > 0:08:23- We couldn't see her face, either. - No, but he knows who it is.
0:08:23 > 0:08:25- He knows who it is.- Right.
0:08:25 > 0:08:29I think... I think it was very striking that Mr Roberts,
0:08:29 > 0:08:31that was an extraordinary state of grief, so...
0:08:31 > 0:08:33- Very emotional, wasn't he? Very emotional.- Very, very emotional.
0:08:33 > 0:08:36- And he's also wearing a wedding ring, so he is married.- Yeah.
0:08:36 > 0:08:38Let me just tell you about the victim.
0:08:38 > 0:08:43We're investigating the death of Ms Emma Kean, who was 50.
0:08:43 > 0:08:46She was an art teacher, and married.
0:08:46 > 0:08:48The cause of death is a suspected heart attack
0:08:48 > 0:08:54and the time of death is approximately 9.40am.
0:08:54 > 0:08:56- So.. - Well, she's an attractive woman.
0:08:56 > 0:08:59- Yes.- Married.
0:09:01 > 0:09:03Could be that she was having a relationship
0:09:03 > 0:09:06with another married teacher.
0:09:06 > 0:09:08Possibly.
0:09:08 > 0:09:10- We also know that she arrived late that day.- Yes.
0:09:10 > 0:09:12- Why was she late? - Why was she late?
0:09:12 > 0:09:14Let me put the suspects up for you
0:09:14 > 0:09:17so we can talk about them a little bit more.
0:09:17 > 0:09:18We've got...
0:09:18 > 0:09:21Miss Gemma Webster, who's a science teacher.
0:09:21 > 0:09:24Mr Ken Roberts, who's the headmaster.
0:09:24 > 0:09:27And Craig Thomas, who's the caretaker.
0:09:27 > 0:09:29- Now, remind me, who found the body? - Ken Roberts.
0:09:29 > 0:09:31- That was Ken Roberts.- Yes.
0:09:31 > 0:09:33- He looked through the hole.- Yes.
0:09:33 > 0:09:35But he said.. Didn't he say that the handle
0:09:35 > 0:09:38- was off the door on both sides? - Yes, the lock was off on both sides.
0:09:38 > 0:09:41- Do you know, I... - When a handle falls off a door,
0:09:41 > 0:09:44- it's normally just on... just on one side, isn't it?- Yes.
0:09:44 > 0:09:48So does that make us believe that she couldn't get out?
0:09:48 > 0:09:50I'm not trusting Ken at the moment.
0:09:50 > 0:09:53- Yeah.- There's something that's been missed.
0:09:53 > 0:09:55- Quite.. Quite emotional, wasn't he? - Yeah.
0:09:55 > 0:09:58So let me try and help you out a bit with your first piece of evidence.
0:09:58 > 0:10:04Here is a still from the CCTV shown by Craig to the detectives.
0:10:04 > 0:10:08So this is what the caretaker was talking about when he said "she" -
0:10:08 > 0:10:11that was his assumption - "is going through the window
0:10:11 > 0:10:13"carrying something."
0:10:13 > 0:10:17Well, that... That looks like a sort of printed carrier bag, doesn't it?
0:10:17 > 0:10:19- Yeah.- Does it?
0:10:19 > 0:10:22They're wearing sort of school uniformy trousers.
0:10:22 > 0:10:259.30am is the timestamp.
0:10:25 > 0:10:26- Yes.- OK.
0:10:26 > 0:10:29- 9.30, it's the time the fire alarm went off.- Went off.- Yeah.
0:10:29 > 0:10:32So does that person know that...
0:10:32 > 0:10:35- has arranged to have the fire alarm set off so that...- As a cover.
0:10:35 > 0:10:37So that she knows that
0:10:37 > 0:10:40that teacher is going to go into the office for the...
0:10:40 > 0:10:43- for the register, to take out to call.- Interesting.
0:10:43 > 0:10:44It is interesting.
0:10:44 > 0:10:47Let's see if we can move further forward in the investigation
0:10:47 > 0:10:49with round two.
0:10:49 > 0:10:51Last Movements.
0:10:51 > 0:10:52Back to Mortcliff College,
0:10:52 > 0:10:55where caretaker Craig has got his hands full.
0:10:55 > 0:10:58Notepads at the ready, off we go.
0:11:08 > 0:11:12Mr Roberts, look, I am sick of cleaning this graffiti.
0:11:12 > 0:11:14We need to put an end to it.
0:11:14 > 0:11:16Right. We need to find out who it is.
0:11:16 > 0:11:19I know who it is. It's that new girl, Penny Kingdom.
0:11:19 > 0:11:22Mr Roberts, could we have a chat about me hiring a new assistant?
0:11:22 > 0:11:25My workload is bigger than everyone else's, and I can't keep up.
0:11:25 > 0:11:27I'm sorry, Ms Webster, there's just no money.
0:11:27 > 0:11:30There wasn't the first time you asked and there isn't now.
0:11:30 > 0:11:32- I'm very sorry. - Well, can't Ms Kean share hers?
0:11:32 > 0:11:35That's not possible, and you know it's not.
0:11:35 > 0:11:38Everyone's busy - not just you.
0:11:38 > 0:11:41How's the planning going for the science trip?
0:11:41 > 0:11:42Fine.
0:11:45 > 0:11:46Hello!
0:11:46 > 0:11:48Nice of you to join us, Ms Kean.
0:11:58 > 0:12:00- There. - Ah, thank you.
0:12:00 > 0:12:02- I thought you might need it. - Kind of.
0:12:02 > 0:12:04Want a brownie? They're from Penny.
0:12:04 > 0:12:07I think she's trying hard to make up for her behaviour.
0:12:10 > 0:12:11You doing a stock-take?
0:12:11 > 0:12:13Just marking art supplies.
0:12:13 > 0:12:16There's been a far amount of spray paint going missing recently.
0:12:16 > 0:12:19Poor Craig has spent hours scrubbing the walls this week.
0:12:26 > 0:12:28FIRE ALARM RINGS
0:12:34 > 0:12:38- Oh, no, I've left the register inside.- I'll go and get it.
0:12:38 > 0:12:41You shouldn't go back inside until we find out what caused the alarm.
0:12:41 > 0:12:43Probably a misbehaved child - come on, that's what it usually is.
0:12:43 > 0:12:46- But you don't know...- It's fine.
0:12:46 > 0:12:49Sorry, we were interrupted earlier. I've had my coffee now.
0:12:49 > 0:12:51What were you saying about this graffiti artist?
0:12:51 > 0:12:53It's definitely Penny Kingdom.
0:12:53 > 0:12:55Only started when she arrived, and she's always in trouble.
0:12:55 > 0:12:57Her and her minions. I'll be back.
0:12:57 > 0:12:59Hi, can I help you?
0:12:59 > 0:13:02I'm Henry Fawcett, the history sub.
0:13:02 > 0:13:04Hi, I'm Mr Roberts, the head.
0:13:04 > 0:13:06Sorry I'm late - trains.
0:13:06 > 0:13:08No problem.
0:13:08 > 0:13:12Sorry about the chaos, we're investigating the fire alarm.
0:13:12 > 0:13:13False alarm, Mr Roberts.
0:13:15 > 0:13:17No problem. Could you send everyone back inside?
0:13:37 > 0:13:38SIREN WAILS
0:13:44 > 0:13:46Hang on...what are you thinking?
0:13:46 > 0:13:52So, first of all...I'm thinking Mr Roberts has lied.
0:13:52 > 0:13:55- Yes.- Because he didn't reset the fire alarm, did he?
0:13:55 > 0:13:57- No.- No, he didn't. - He's outside. Yeah.
0:13:57 > 0:14:00He delivered a drink to Ms Kean,
0:14:00 > 0:14:02he left it with one sugar on the desk
0:14:02 > 0:14:05while she was labelling up the spray paint.
0:14:05 > 0:14:08- Spray paint's been going missing. - Yeah.
0:14:08 > 0:14:12The person that they think has been doing the spray-painting is Penny.
0:14:12 > 0:14:16Yeah, so Penny gave brownies to Ms Kean to make up for her behaviour.
0:14:16 > 0:14:19- Yep.- I.. I found it quite significant
0:14:19 > 0:14:21when the headmaster said rather ostentatiously,
0:14:21 > 0:14:24"Oh, dear, I have forgotten the register,"
0:14:24 > 0:14:26and she said, "Oh, I'll go and get it,"
0:14:26 > 0:14:29and there was something about the way he did that.
0:14:29 > 0:14:33We can now add Mr Henry Fawcett, the substitute teacher,
0:14:33 > 0:14:38and Penny Kingdom, who we've not met yet.
0:14:38 > 0:14:40So..
0:14:40 > 0:14:42Don't know if anybody else picked up
0:14:42 > 0:14:45- but it seems that Gemma wasn't fond of Mrs Kean.- Yeah.
0:14:45 > 0:14:48She spoke about her heavy workload.
0:14:48 > 0:14:51- Mr Roberts passed it off.- Yeah.
0:14:51 > 0:14:53Let's try and move it forward.
0:14:53 > 0:14:56It's time to pick your next piece of evidence.
0:14:56 > 0:15:01We have the graffiti message on the wall that Craig was cleaning,
0:15:01 > 0:15:04a police report on the office door barged open
0:15:04 > 0:15:06before discovering the victim,
0:15:06 > 0:15:11and finally, a police report on the school fire alarm box.
0:15:11 > 0:15:14- Something's drawing me towards the graffiti.- Oh, is it?
0:15:14 > 0:15:19Yeah, and it's kind of one of the most obvious, I think,
0:15:19 > 0:15:21to not go for, but it could be
0:15:21 > 0:15:23somebody trying to set somebody else up.
0:15:23 > 0:15:26Could it be a rude... A rude poem or a rude slogan
0:15:26 > 0:15:29about "Miss So-and-so and Mr So-and-so are..."
0:15:29 > 0:15:31Yeah, possibly.
0:15:31 > 0:15:34I'm... I'm inclined to go to the office door at the moment.
0:15:34 > 0:15:36Let's go for the office door.
0:15:36 > 0:15:38OK, let's see the office door.
0:15:38 > 0:15:42Door handle totally detached,
0:15:42 > 0:15:46witness reports state door jammed closed.
0:15:47 > 0:15:51Possibility of tampering not definitive.
0:15:51 > 0:15:54It's not necessarily that it hasn't been tampered with,
0:15:54 > 0:15:57- they just can't prove it. - There's no proof there, is there?
0:15:57 > 0:16:00It looks like the handle could have just fallen off.
0:16:00 > 0:16:03Apart from the marks where probably the handle was fitted
0:16:03 > 0:16:06in the first place, there doesn't appear to be any marks round the...
0:16:06 > 0:16:09- the catch, does there? - Why did Mr Roberts say
0:16:09 > 0:16:13you could only see her by looking through the hole?
0:16:13 > 0:16:15There's windows in the door!
0:16:15 > 0:16:16ALL: Ohhh!
0:16:16 > 0:16:18APPLAUSE
0:16:19 > 0:16:22I didn't even notice that, James,
0:16:22 > 0:16:25and I'm this close to the screen!
0:16:25 > 0:16:27There's a window!
0:16:27 > 0:16:30So we now know, I mean, that's two lies we've caught him in now.
0:16:30 > 0:16:32- Two lies, yeah.- Very interesting.
0:16:32 > 0:16:35It's that moment, Armchair Detectives, to write down
0:16:35 > 0:16:36and name your prime suspect.
0:16:36 > 0:16:39Will it be Gemma, Ken,
0:16:39 > 0:16:42Craig, Henry, or Penny?
0:16:47 > 0:16:50It's time to find out who your prime suspects are.
0:16:50 > 0:16:52James, who have you gone for?
0:16:52 > 0:16:54- Ken Roberts, the headmaster. - Why?
0:16:54 > 0:16:58There's a lot of lies coming out of his mouth at the moment.
0:16:58 > 0:17:01Call it a copper's nose, but I'm bit suspicious of him at the moment.
0:17:01 > 0:17:05- Kathryn. - I have gone for the same chap, Ken.
0:17:05 > 0:17:07As James said, we've..
0:17:07 > 0:17:10we've detected him in not one, but two lies,
0:17:10 > 0:17:13and also there was something odd about his grief, it was...
0:17:13 > 0:17:15There was a touch of the theatrical about it.
0:17:15 > 0:17:17Yes, it was a little bit theatrical.
0:17:17 > 0:17:19Bola, what do you think? Who's your prime suspect?
0:17:19 > 0:17:22I've gone for Ken Roberts also.
0:17:22 > 0:17:25- Full house. Full house. - Yes.
0:17:25 > 0:17:29It's probably the most emotion we've kind of seen,
0:17:29 > 0:17:31but also it was... It didn't feel genuine.
0:17:31 > 0:17:36Yes. So in summary, every single one of our Armchair Detectives
0:17:36 > 0:17:37thinks it's Ken.
0:17:37 > 0:17:40Let's see what happens now - it's on to round three,
0:17:40 > 0:17:41the Police Interviews.
0:17:41 > 0:17:46Knight and Slater have called in Penny and Craig for questioning.
0:17:46 > 0:17:49Who's hiding secrets in this textbook case?
0:17:49 > 0:17:51It's off to Mortcliff Police Station.
0:18:01 > 0:18:02Further searches in the school
0:18:02 > 0:18:04revealed something pretty interesting.
0:18:04 > 0:18:09The victim was poisoned, an unusual chemical for a school lab.
0:18:09 > 0:18:10Sodium azide.
0:18:12 > 0:18:14Yeah, no, that is quite unusual, Simmons.
0:18:15 > 0:18:18I did tell you I was a science boffin, sir.
0:18:19 > 0:18:21Anything else?
0:18:21 > 0:18:25May have something, but just need to confirm a few things.
0:18:25 > 0:18:27I'll keep you in the loop.
0:18:27 > 0:18:29Oh, there were loose screws in the room we found the body.
0:18:29 > 0:18:32I'd say the door had been tampered with.
0:18:38 > 0:18:42What were you doing on Wednesday morning around 9.15?
0:18:44 > 0:18:45At school.
0:18:46 > 0:18:48Whereabouts?
0:18:49 > 0:18:52I was evacuating the building because of the alarm.
0:18:52 > 0:18:56That's interesting, because, you see, we have CCTV pictures
0:18:56 > 0:19:00showing that everyone else was rushing out of the building,
0:19:00 > 0:19:03while you were actually climbing back in.
0:19:08 > 0:19:14You have quite a track record for vandalism and truancy, Miss Kingdom.
0:19:15 > 0:19:17Early starter, too.
0:19:17 > 0:19:20No suggestion of physically violent behaviour,
0:19:20 > 0:19:22but there's always a first time, I suppose.
0:19:22 > 0:19:23I hurt no-one, pal.
0:19:23 > 0:19:26Well, you see, I can't really take that at face value
0:19:26 > 0:19:30if you continue to refuse to tell us exactly what you were doing
0:19:30 > 0:19:31at the time Ms Kean was murdered.
0:19:36 > 0:19:37I...
0:19:39 > 0:19:42I stole some spray paint from the art department.
0:19:42 > 0:19:44I wanted to do some graffiti.
0:19:44 > 0:19:45Why was that?
0:19:45 > 0:19:48That creep Mr Thomas is out to get me,
0:19:48 > 0:19:50so I thought I'd give him something to moan about.
0:19:55 > 0:19:58I knew it was Penny Kingdom doing the graffiti.
0:19:58 > 0:20:00It didn't take a rocket scientist to work it out.
0:20:00 > 0:20:02It started when she came to the school.
0:20:04 > 0:20:05Did you threaten her?
0:20:05 > 0:20:08No. I told her she was a criminal, and she is.
0:20:08 > 0:20:12The graffiti she wrote appears as though it was directed at you.
0:20:14 > 0:20:15What does it mean, exactly?
0:20:15 > 0:20:17I have no idea.
0:20:17 > 0:20:18Mr Thomas...
0:20:20 > 0:20:25..we have Ms Kean's mobile phone records.
0:20:26 > 0:20:31It appears that she made calls from your address
0:20:31 > 0:20:34on three separate occasions over the last two weeks.
0:20:35 > 0:20:37After school hours.
0:20:40 > 0:20:42Can you tell us what she was doing at your house?
0:20:44 > 0:20:46Well, she wanted to ask my opinion
0:20:46 > 0:20:49on plans the school had for renovations.
0:20:49 > 0:20:51At ten o'clock at night?
0:20:51 > 0:20:55In summer, one loses track of time.
0:20:55 > 0:20:57What do you think of Mr Roberts?
0:20:57 > 0:20:59Do you mean do I think he killed her?
0:20:59 > 0:21:03I think Mr Roberts and Ms Kean had a pretty decent relationship,
0:21:03 > 0:21:05you know, seemed to get on well enough.
0:21:05 > 0:21:06I don't think that's important.
0:21:06 > 0:21:09I'd look at Penny. Honestly, she's a disaster,
0:21:09 > 0:21:12and I think she's gone too far this time.
0:21:16 > 0:21:21"In summer, one loses track of time." Oh, really, Mr Thomas?
0:21:21 > 0:21:24Eh, eh? We met Penny - what do we think of her?
0:21:24 > 0:21:27What I noticed initially, I thought, "Ohh!"
0:21:27 > 0:21:29was the spray paint on her fingers.
0:21:29 > 0:21:31Yeah, I noticed that, the blue spray paint.
0:21:31 > 0:21:32Yeah, the blue spray paint.
0:21:32 > 0:21:35In actual fact, she even admitted stealing it.
0:21:35 > 0:21:38It was also hinted during the interviews
0:21:38 > 0:21:41that the graffiti relates to Craig Thomas.
0:21:41 > 0:21:44- Thomas, yeah.- Yeah. - So has Penny discovered
0:21:44 > 0:21:49that Craig Thomas and Mrs Kean are maybe having a...?
0:21:49 > 0:21:52I definitely think so, I definitely think so.
0:21:52 > 0:21:54What we also found out on this video
0:21:54 > 0:21:57was that she was killed by poisoning.
0:21:57 > 0:21:59I do think it's through the coffee,
0:21:59 > 0:22:02because coffee is featuring a lot in these videos.
0:22:02 > 0:22:04There's a lot of coffee.
0:22:04 > 0:22:06Let's try and help you out with some more evidence,
0:22:06 > 0:22:08see if we can move this forward.
0:22:08 > 0:22:11Once again, you can pick a piece of evidence from the list.
0:22:11 > 0:22:14The graffiti message on the wall that Craig was cleaning,
0:22:14 > 0:22:17a police report on the school fire alarm,
0:22:17 > 0:22:18or the new piece of evidence,
0:22:18 > 0:22:23which is the sodium azide bottle from the school lab.
0:22:23 > 0:22:26I'm still curious about the graffiti, I'm going to be honest,
0:22:26 > 0:22:29and the police officer didn't state that it was about Craig,
0:22:29 > 0:22:32- AND Mrs Kean, he just said it was about him.- No, about him.
0:22:32 > 0:22:36- Penny referred to him in her interview as a creep.- Exactly, yeah.
0:22:36 > 0:22:37I'm interested in the fire alarm,
0:22:37 > 0:22:41but I'm also interested in the sodium azide bottle,
0:22:41 > 0:22:44especially when Ms Webster's the chemistry teacher.
0:22:45 > 0:22:47- Oh...- Oh, hello, James.
0:22:47 > 0:22:50What do you want to see, Armchair Detectives?
0:22:50 > 0:22:53Right. Based on what you've just said, the last bit,
0:22:53 > 0:22:55I'm going to swing from graffiti to...
0:22:55 > 0:22:57- yeah, the sodium azide. - The sodium?- Yes.
0:22:57 > 0:22:59- The sodium azide bottle, yes? - Yeah.- Yeah?- Yes.
0:22:59 > 0:23:01OK, let's see the bottle.
0:23:01 > 0:23:04Sodium azide is a highly toxic substance
0:23:04 > 0:23:06and is poisonous if consumed.
0:23:06 > 0:23:12The bottle states that the substance should be handled with extreme care.
0:23:12 > 0:23:18Explodes when a small electrical current is passed through it.
0:23:18 > 0:23:19Heart attack.
0:23:19 > 0:23:22It's time to pick your prime suspect again.
0:23:22 > 0:23:24Let's have a look at the board.
0:23:24 > 0:23:26Is it Gemma, Ken,
0:23:26 > 0:23:28Craig, Henry, or Penny?
0:23:28 > 0:23:31Please write down your prime suspect now.
0:23:36 > 0:23:39Let's see who your prime suspects are.
0:23:39 > 0:23:42James, last time you went for Ken - this time?
0:23:42 > 0:23:45- I've went for Ken again. - Ken again?
0:23:45 > 0:23:48Yes. There's still a lot of inconsistencies
0:23:48 > 0:23:51that have not been answered yet.
0:23:51 > 0:23:55Kathryn, last time you went for Ken, who have you gone for this time?
0:23:55 > 0:23:58- I'm sticking with Ken. - Sticking with Ken?- His...
0:23:58 > 0:24:01His lies, his ostentatious grief,
0:24:01 > 0:24:05there's just something that I find very uneasy-making about him.
0:24:05 > 0:24:08Something not right. As my mum would say, something not right.
0:24:08 > 0:24:11- He's a bit shifty.- Bola.- Yes. - Last time you went for Ken.
0:24:11 > 0:24:13Yes. I'm sticking.
0:24:13 > 0:24:15- Sticking with Ken.- Yes.
0:24:15 > 0:24:17- Still all Kens.- Yes.
0:24:17 > 0:24:22I'm going to be honest, I am curious about Ms Webster,
0:24:22 > 0:24:26- that's where I'm at, but I've not had enough evidence yet.- Yeah.
0:24:26 > 0:24:30OK, to summarise, then, all of our Armchair Detectives
0:24:30 > 0:24:32think that Ken is the prime suspect.
0:24:32 > 0:24:35It's time now for round four - Dig Deeper.
0:24:35 > 0:24:39Notepads at the ready as we head back to Mortcliff College
0:24:39 > 0:24:41and to the art classroom.
0:24:49 > 0:24:52That's lovely - well done.
0:24:52 > 0:24:53Good girl, Penny.
0:24:54 > 0:24:57Um, yes, the red, a bit more.
0:25:05 > 0:25:06BELL RINGS
0:25:06 > 0:25:10Thank you, everybody. Please put everything away neatly.
0:25:19 > 0:25:22Penny, detention is in here this afternoon, please stay seated.
0:25:43 > 0:25:44DOOR OPENS
0:25:46 > 0:25:49Penny. Only you in detention today?
0:25:49 > 0:25:51I guess so, sir.
0:25:51 > 0:25:52What homework do you have?
0:25:52 > 0:25:54Science and English.
0:25:54 > 0:25:56OK, start with science, and we'll see how we go.
0:26:06 > 0:26:08PHONE VIBRATES
0:26:18 > 0:26:20Sir.
0:26:20 > 0:26:23Honestly. What part of detention don't you understand?
0:26:23 > 0:26:25Come on now, hand it over.
0:26:25 > 0:26:27Now.
0:26:29 > 0:26:30Sir...
0:26:30 > 0:26:32Miss Webster's the best.
0:26:32 > 0:26:35Today she showed us how an airbag blows up
0:26:35 > 0:26:37using this deadly chemical.
0:26:37 > 0:26:39It's this stuff, right,
0:26:39 > 0:26:43and when it explodes it creates all this gas. It's magic.
0:26:43 > 0:26:46And dangerous. We could only touch it with gloves.
0:26:46 > 0:26:49You were a science teacher once, weren't you, sir?
0:26:50 > 0:26:52Sir.
0:26:52 > 0:26:54I know I've been really difficult,
0:26:54 > 0:26:57but actually, this is the best school.
0:26:57 > 0:27:01The other four I've gone to weren't nearly as good.
0:27:03 > 0:27:04Right.
0:27:05 > 0:27:07Thank you, Penny.
0:27:08 > 0:27:09- Really?- Really.
0:27:11 > 0:27:13I'm...glad you like science.
0:27:14 > 0:27:16I'm going to let you go early,
0:27:16 > 0:27:20in the hope that your troubled behaviour has come to an end.
0:27:20 > 0:27:24Yes, for sure. I promise you. You won't regret it, sir.
0:27:27 > 0:27:29Sir,
0:27:29 > 0:27:32do you really like Ms Kean like that?
0:27:32 > 0:27:34Like, to have an affair with her?
0:27:35 > 0:27:38I can't have an affair with my own wife, Penny.
0:27:46 > 0:27:50Ohh! You've got another 15 minutes yet.
0:27:50 > 0:27:54- Does Mr Roberts know you're off? - You ought to mind your own business.
0:27:54 > 0:27:56I know girls like you.
0:27:56 > 0:28:00Troublemakers, vandals, criminals.
0:28:00 > 0:28:02I'll get you expelled.
0:28:02 > 0:28:03Is that a fact?
0:28:04 > 0:28:08Watch this space. Then you'll really know what I'm capable of.
0:28:16 > 0:28:18All right, Mr Roberts?
0:28:18 > 0:28:20All right, Mr Thomas. Have a good evening.
0:28:28 > 0:28:29Boof!
0:28:29 > 0:28:31Armchair Detectives, huge things happened.
0:28:31 > 0:28:33I just wanted confirmation from my colleagues.
0:28:33 > 0:28:36So, do I understand that Ms Kean is actually Mrs Roberts?
0:28:36 > 0:28:41Does this maybe explain why he was so upset when she died?
0:28:41 > 0:28:45Yes, but why would he not say, "I'm married to her"?
0:28:45 > 0:28:47- I mean, what... - I don't know, James!
0:28:47 > 0:28:51I've just got a little theory that...
0:28:51 > 0:28:53Penny knew it all,
0:28:53 > 0:28:55she knew that Ms Kean
0:28:55 > 0:28:59was spending time with Craig...
0:28:59 > 0:29:00Yeah.
0:29:00 > 0:29:04..and she obviously was messaging about seeing her with Mr Roberts...
0:29:04 > 0:29:05Yeah.
0:29:05 > 0:29:08- He's gone through her message history on her phone...- Yeah.
0:29:08 > 0:29:11..and maybe worked out that his wife is having an affair...
0:29:13 > 0:29:14..with Mr Thomas.
0:29:14 > 0:29:17- APPLAUSE - Thanks.
0:29:17 > 0:29:19James.
0:29:19 > 0:29:22We also know that Mr Roberts used to be a science teacher.
0:29:22 > 0:29:24Yeah, now, we've been talking about her being poisoned,
0:29:24 > 0:29:26she can't have ingested it.
0:29:26 > 0:29:28Well, coffee...
0:29:28 > 0:29:30A cup of coffee was delivered by Ken Roberts
0:29:30 > 0:29:31when she was in the classroom.
0:29:31 > 0:29:33- Yes.- Yeah.
0:29:33 > 0:29:36So, here are the suspects for the case, the board is now full.
0:29:36 > 0:29:38That's all of your suspects.
0:29:38 > 0:29:41There's still some unanswered questions with Penny.
0:29:41 > 0:29:43She did threaten Craig.
0:29:43 > 0:29:47Is it possible that he's been up to something untoward?
0:29:47 > 0:29:48And she...
0:29:48 > 0:29:52I don't know, maybe she's jealous of somebody.
0:29:52 > 0:29:55So, once again, you get to pick a piece of evidence
0:29:55 > 0:29:56from three choices.
0:29:56 > 0:29:57There's a new item on the list.
0:29:57 > 0:30:01So, the graffiti message on the wall that Craig was cleaning.
0:30:01 > 0:30:03A police report on the school fire alarm box.
0:30:03 > 0:30:10And a new item, which is text messages from Penny's mobile phone.
0:30:10 > 0:30:13I want to see this graffiti, what is it referring to?
0:30:13 > 0:30:14I know.
0:30:14 > 0:30:15But...
0:30:15 > 0:30:17What has she got over him?
0:30:17 > 0:30:18Bola's so convinced, I...
0:30:18 > 0:30:21I think I'd like to have a look at it, it might have a shade on...
0:30:21 > 0:30:23- Graffiti?- Graffiti.
0:30:23 > 0:30:25We're going to take a look at the graffiti.
0:30:25 > 0:30:26I did want to see the texts.
0:30:26 > 0:30:31- "I know..."- Oh, wow. - "..what you did, Craig."
0:30:31 > 0:30:34And it looks like somebody's
0:30:34 > 0:30:37tried to hide what that says.
0:30:37 > 0:30:39Oh, does it say something else as well?
0:30:39 > 0:30:41It does, hang on.
0:30:41 > 0:30:42What does it say?
0:30:42 > 0:30:44The last letter on the...
0:30:44 > 0:30:47has been turned into an R, A...
0:30:47 > 0:30:50Oh, there's something there and I can't see it.
0:30:50 > 0:30:52Hey, James, quite a good clue?
0:30:54 > 0:30:55I went with it!
0:30:55 > 0:30:56THEY LAUGH
0:30:56 > 0:30:58Didn't take long.
0:30:58 > 0:31:00Well, we're going to have to move on.
0:31:00 > 0:31:02So, let's get the suspects back up again.
0:31:02 > 0:31:05Gemma, Ken, Craig, Henry, Penny.
0:31:05 > 0:31:07Write them down for me.
0:31:12 > 0:31:15Notepads down, please.
0:31:15 > 0:31:17James, last time, you went for Ken.
0:31:17 > 0:31:19Yeah.
0:31:19 > 0:31:20Who's your prime suspect this time?
0:31:20 > 0:31:22I've stuck with Ken.
0:31:22 > 0:31:23Ken. Nothing has changed your mind?
0:31:23 > 0:31:26No. I've still got so many unanswered questions.
0:31:26 > 0:31:29Kathryn, last time, you went for Ken.
0:31:29 > 0:31:32I.. I stuck with Ken,
0:31:32 > 0:31:34but I now have serious misgivings
0:31:34 > 0:31:36about having done so.
0:31:36 > 0:31:37- Why?- Well, I wonder...
0:31:37 > 0:31:39I don't know for certain,
0:31:39 > 0:31:43but I wondered if, what you could see in...
0:31:43 > 0:31:46Written against that was sodium azide.
0:31:46 > 0:31:48OK. Interesting theory.
0:31:48 > 0:31:50Bola, last time, you went for Ken.
0:31:50 > 0:31:52- Have you stuck with Ken? - Yes, I have.
0:31:52 > 0:31:54Because?
0:31:54 > 0:31:56In the morning, when she was late,
0:31:56 > 0:31:58he was kind of offish with her.
0:31:58 > 0:32:00- Yes.- "Nice of you to turn up."
0:32:00 > 0:32:03Why would you not, kind of, come together
0:32:03 > 0:32:04or leave around the same time?
0:32:04 > 0:32:07Did they not leave the same house in the morning? I'm confused.
0:32:07 > 0:32:08Yes.
0:32:08 > 0:32:10Where was...? Indeed, where was...?
0:32:10 > 0:32:12- Where was she?- Yeah.
0:32:12 > 0:32:16The prime suspect for everyone is Ken,
0:32:16 > 0:32:19lots of questions around Ken.
0:32:19 > 0:32:22But it's time now for round five, the Final Clues.
0:32:22 > 0:32:26Are we any closer to solving this art attack?
0:32:26 > 0:32:27Notepads at the ready,
0:32:27 > 0:32:30let's go back to Mortcliff.
0:32:40 > 0:32:41KNOCK AT DOOR
0:32:41 > 0:32:43Come in.
0:32:43 > 0:32:44Oh, hello again.
0:32:44 > 0:32:46Is everything OK?
0:32:46 > 0:32:48Mr Thomas...
0:32:48 > 0:32:51were you having an affair with Ms Kean?
0:32:51 > 0:32:53No. Absolutely not.
0:32:53 > 0:32:55Really?
0:32:55 > 0:32:58So you didn't string her along and then call the whole thing off?
0:32:58 > 0:33:00Where has this come from?
0:33:00 > 0:33:04We've retrieved the last text message Ms Kean sent to you
0:33:04 > 0:33:06from her mobile phone, which reads...
0:33:06 > 0:33:09"I cannot believe I almost chose mediocre passion
0:33:09 > 0:33:12"over the special friendship I've always had, dot, dot, dot,
0:33:12 > 0:33:15"thank you for helping me see the error of my ways.
0:33:15 > 0:33:16"Full stop."
0:33:17 > 0:33:20The woman was a cling-on, seriously.
0:33:20 > 0:33:22She didn't understand when enough was enough
0:33:22 > 0:33:25but, I swear to you, I had nothing to do with her death.
0:33:25 > 0:33:26Speak to Ms Webster,
0:33:26 > 0:33:29she was desperate to get the deputy head teacher position,
0:33:29 > 0:33:31but Mr Roberts gave it to Ms Kean,
0:33:31 > 0:33:33OBVIOUSLY, who didn't really deserve it.
0:33:33 > 0:33:36If anyone had a reason to wish Emma Kean dead, it was her.
0:33:42 > 0:33:43Ms Webster, hello.
0:33:43 > 0:33:45Hello.
0:33:45 > 0:33:48I've never seen a lab so pristine.
0:33:48 > 0:33:49Thank you.
0:33:49 > 0:33:51You must be a huge asset to the school.
0:33:51 > 0:33:53Well you would have thought so, wouldn't you?
0:33:53 > 0:33:55How can I help you today?
0:33:55 > 0:33:58We were wondering if we could ask you some questions
0:33:58 > 0:33:59regarding Penny Kingdom.
0:33:59 > 0:34:02And we'd appreciate your expert opinion.
0:34:02 > 0:34:06Do you know a chemical called sodium azide?
0:34:06 > 0:34:08Yes. Not many schools have it,
0:34:08 > 0:34:10but I got some in for a specific experiment.
0:34:19 > 0:34:22That's odd, it's out of its place.
0:34:22 > 0:34:24I always keep everything in alphabetical order.
0:34:24 > 0:34:26It should be sodium azide first,
0:34:26 > 0:34:28then sodium bicarbonate,
0:34:28 > 0:34:29sodium chloride,
0:34:29 > 0:34:31then sodium hydroxide.
0:34:31 > 0:34:32So orderly.
0:34:32 > 0:34:34Well, OCD, really.
0:34:34 > 0:34:35Me, too.
0:34:35 > 0:34:38So, the sodium azide was used
0:34:38 > 0:34:41and then put back in the wrong place.
0:34:41 > 0:34:44Sir, I'd be extremely careful touching that,
0:34:44 > 0:34:46- it can be very harmful.- OK.
0:34:53 > 0:34:54We'll need to take this away...
0:34:56 > 0:34:57..as evidence.
0:34:59 > 0:35:02- There's so much going on. - I know.
0:35:02 > 0:35:04Tell me, Armchair Detectives.
0:35:04 > 0:35:06I mean, to work backwards...
0:35:08 > 0:35:10..Miss Webster, there, seemed genuinely gobsmacked
0:35:10 > 0:35:14when she opened the cupboard and saw that the sodium azide was...
0:35:14 > 0:35:16missing, so I...
0:35:16 > 0:35:20I'm inclined to scratch her from the runners and riders in this.
0:35:20 > 0:35:25Craig seemed very angry, didn't he?
0:35:25 > 0:35:27And also, he was very quick...
0:35:27 > 0:35:30very, very quick to put the blame on somebody else.
0:35:30 > 0:35:31Exactly.
0:35:31 > 0:35:36Someone's been in that cupboard and they've took the...sodium azide.
0:35:36 > 0:35:38- And put it back.- And put it back.
0:35:38 > 0:35:40And it's under lock and key.
0:35:40 > 0:35:43One more piece of evidence, Armchair Detectives.
0:35:43 > 0:35:47So, do you want a police report on the school fire alarm box
0:35:47 > 0:35:52or the text messages from Penny's mobile phone?
0:35:52 > 0:35:55- My instinct is to go for Penny's texts.- Yep.
0:35:55 > 0:35:58Because clearly, there was something that the headmaster saw in them
0:35:58 > 0:36:01that made him suddenly turn into Mr Nice Guy.
0:36:01 > 0:36:04I do really want to see the fire alarm report,
0:36:04 > 0:36:05cos someone put...
0:36:05 > 0:36:08Someone set this fire alarm off deliberately.
0:36:10 > 0:36:12Let's go for Penny's texts.
0:36:12 > 0:36:16OK, decision made. Let's see Penny's texts.
0:36:16 > 0:36:17So...
0:36:28 > 0:36:30That's it, that's what he's seen.
0:36:30 > 0:36:31- He's found out...- Yes.
0:36:31 > 0:36:33..that she's with...
0:36:33 > 0:36:36- Over the side with the caretaker. - The caretaker.
0:36:36 > 0:36:39And that's why he turned into Mr Nice Guy
0:36:39 > 0:36:41once he started reading the...
0:36:41 > 0:36:43- And let her go. - And let her go.
0:36:43 > 0:36:45And that's why Penny's put it on the...graffiti.
0:36:45 > 0:36:47So, you're thinking that...
0:36:47 > 0:36:49- Mr Roberts...- Yes.
0:36:49 > 0:36:51- ..saw that she was on her phone, picked up the text.- Yeah.
0:36:51 > 0:36:55Obviously saw that she was talking about him and Ms Kean.
0:36:55 > 0:36:56- Just after that...- Yeah.
0:36:56 > 0:36:58..you saw the caretaker, Craig Thomas,
0:36:58 > 0:37:01and Ken together in the corridor,
0:37:01 > 0:37:03and Ken didn't want to speak to him.
0:37:03 > 0:37:06It's the final moment we've all been waiting for.
0:37:06 > 0:37:07Stop.
0:37:07 > 0:37:09You're about to make your accusations.
0:37:09 > 0:37:11Who will get the Golden Magnifying Glass?
0:37:14 > 0:37:18It's time to answer the only question that matters...
0:37:18 > 0:37:20Whodunnit?
0:37:26 > 0:37:28Armchair Detectives, pads down.
0:37:29 > 0:37:33James, who are you accusing?
0:37:33 > 0:37:36- I've stuck with Ken.- Ken.- Yeah.
0:37:36 > 0:37:39I think he's got the motive, that he's found out that his wife
0:37:39 > 0:37:41is having an affair,
0:37:41 > 0:37:44that he's had the means - he used to be a science teacher,
0:37:44 > 0:37:47and there was a lot of lies still unaccounted for.
0:37:47 > 0:37:49Kathryn, who are you accusing?
0:37:49 > 0:37:51I'm still with Ken for the same reasons,
0:37:51 > 0:37:55there's unexplained lies, and also there's that convenient thing right
0:37:55 > 0:37:59at the beginning where he said, "Oh, I've forgotten the register,"
0:37:59 > 0:38:02so I think he's rigged something in that...
0:38:02 > 0:38:03..in that room.
0:38:03 > 0:38:08- Bola.- I've stuck with Ken.- Ken.
0:38:08 > 0:38:15All three of our Armchair Detectives are accusing Ken of the crime.
0:38:15 > 0:38:18Now, you didn't pick this last piece of evidence.
0:38:18 > 0:38:24Alarm is activated and accessed by a key, alarm box not tampered.
0:38:24 > 0:38:28It's not been tampered with, so it is someone that's got access to it,
0:38:28 > 0:38:32so that rules out, like, a pupil and the teachers...
0:38:32 > 0:38:39The people that had access to it is Ken Roberts and also Craig Thomas.
0:38:39 > 0:38:44What really happened in today's story - School's Out for Murder?
0:38:44 > 0:38:49Who killed Miss Emma Kean? Let's find out whodunnit.
0:39:02 > 0:39:05How well does Craig Thomas know his periodic table?
0:39:05 > 0:39:09Well...but Gemma Webster?
0:39:09 > 0:39:13She's very knowledgeable on chemicals and their effects.
0:39:13 > 0:39:16And who was overlooked for a well-deserved promotion, sir?
0:39:16 > 0:39:18Could well be a woman.
0:39:20 > 0:39:25The fire alarm was activated so Emma Kean would be trapped
0:39:25 > 0:39:30inside that office. The sodium azide was already in the chemistry lab.
0:39:32 > 0:39:35Is Gemma Webster an improviser or a careful planner?
0:39:35 > 0:39:39Careful planner for sure, sir, takes one to know one.
0:39:40 > 0:39:43Far too careful to use something from her own lab.
0:39:45 > 0:39:46Penny Kingdom.
0:39:47 > 0:39:51Lost child, hardened by circumstance and neglect.
0:39:51 > 0:39:53That's a poetic analysis, Slater.
0:39:54 > 0:39:58- Do try, sir.- But was Penny hardened enough to kill?
0:40:00 > 0:40:04No, I think if she did kill, it would be a spontaneous act.
0:40:04 > 0:40:05I agree.
0:40:12 > 0:40:15So we've had updates on the crime scene evidence.
0:40:17 > 0:40:22It seems the office phone had been disabled.
0:40:27 > 0:40:31- Had it?- And the door handle had been removed,
0:40:31 > 0:40:34meaning Ms Kean couldn't get out of the office.
0:40:34 > 0:40:36And tiny crystals of sodium azide
0:40:36 > 0:40:39were found in the art department bin.
0:40:43 > 0:40:48How on earth am I supposed to know what my wife or any other student
0:40:48 > 0:40:49dumps into a bin?
0:40:49 > 0:40:52Can you imagine why anyone would add sugar to a cup of coffee
0:40:52 > 0:40:56in the classroom when they could have done it in the staff room?
0:40:56 > 0:40:59And if you're taking coffee to someone you know, wouldn't you
0:40:59 > 0:41:01just add the sugar yourself?
0:41:03 > 0:41:06Are you insinuating that I put poison in her coffee?
0:41:06 > 0:41:08What a ludicrous claim.
0:41:08 > 0:41:11The person you should really be talking to is Penny Kingdom -
0:41:11 > 0:41:13she could have poisoned any one of us.
0:41:13 > 0:41:16I don't think so. Sodium azide is a nasty poison,
0:41:16 > 0:41:18but it doesn't kill instantly.
0:41:19 > 0:41:22Slater knows his periodic table, as I'm sure do you,
0:41:22 > 0:41:24having been a science teacher for many years.
0:41:24 > 0:41:26You can't just take...
0:41:26 > 0:41:29And I also believe you knew your wife was having an affair
0:41:29 > 0:41:30with Craig Thomas.
0:41:38 > 0:41:39He wasn't the first, either.
0:41:42 > 0:41:44He probably wouldn't have been the last.
0:41:48 > 0:41:53Penny Kingdom knew. She was telling the whole school.
0:41:53 > 0:41:54I was a laughing stock.
0:42:02 > 0:42:07The message at the bottom of this page is the last text
0:42:07 > 0:42:08she sent to Craig Thomas.
0:42:14 > 0:42:17It appears she realised your worth after all.
0:42:17 > 0:42:19HE SOBS
0:42:26 > 0:42:30Well done, Armchair Detectives - you all caught today's killer
0:42:30 > 0:42:32and Bola's got her first gold magnifying glass trophy!
0:42:35 > 0:42:36Oh, dear.
0:42:38 > 0:42:40Armchair Detectives, how many of you got that right?
0:42:42 > 0:42:46Yeah, see, I keep thinking it's too obvious and going for the wrong one.
0:42:46 > 0:42:49Come back tomorrow where we'll see Knight and Slater
0:42:49 > 0:42:52mix with the tweed-wearing upper class of Mortcliff
0:42:52 > 0:42:56as they investigate a crime at a stunning country house.
0:42:57 > 0:43:03And remember, no-one gets away with murder in Mortcliff. Goodbye.
0:43:04 > 0:43:07- Well done, darling.- Thank you.
0:43:07 > 0:43:08Well done, sweetie.
0:43:08 > 0:43:10Well done, darling.
