00:00How was your day?
00:02Someone murdered a tour guide in a church.
00:05I mean, in terms of our investigation.
00:07Well, I've actually been looking over the original crime scene.
00:09No, John, what you were supposed to do today is get closer to D.I. Carter.
00:13This Russell character magically appeared at the exact same time as James vanished.
00:18I was engaged.
00:19She died.
00:20Her name was Mandy Ziegler.
00:23As in?
00:24Helped a fast track transfer.
00:26That's all I've ever asked of him.
00:27The Sinclair case is Roger Sinclair, single man disturbed a burglar who killed him in
00:34a panic of self-preservation.
00:36Sinclair was a conspiracy theorist and a pretty batty one at that.
00:38I have been looking into this guy they arrested, Reese Bowen.
00:41He lives with his mother.
00:43He was with me that whole evening, so I told the police, but they wouldn't believe me.
00:47He's dead.
00:48Well, I was supposed to talk to him today.
00:50What if they knew that?
00:51The man was facing life in prison for a crime he didn't commit.
00:55Shadowy figures orchestrating a suicide inside a guarded prison cell.
01:02No, it's too much.
01:04It's too big.
01:55Oh, come on!
02:02Oh, God.
02:06Marty!
02:08Marty!
02:25John, wake up.
02:48Ah!
02:49What are you doing?
02:50The famous detective awakes.
02:53Congratulations, page five.
03:08That's me.
03:09Not according to that it isn't.
03:11According to that, it's Supercop DCI James Taylor.
03:14Supercop?
03:15Is that what it says?
03:17What on earth were you thinking?
03:19How's this my fault?
03:20I didn't know I was going to be in the paper.
03:22You gave them a quote, John.
03:25As with most investigations of this nature, it was simply a case of whittling down the variables.
03:30That woman was a journalist?
03:32Who did you think she was?
03:34A fan?
03:35She can't go plastering herself all over the newspaper like this.
03:38God only knows who might have seen it.
03:40Maybe Dad has.
03:44And if he has, maybe he'll get in touch.
03:49Oh, Henry, you don't understand. We have to be careful about this sort of thing.
03:52Why? Because he told us to.
03:54He also told us to leave town. We didn't do that, did we?
03:57If he sees we haven't been following his instructions, maybe it'll force his hand.
04:02And bring him home.
04:05You do want him to come home, don't you, Mum?
04:07Henry!
04:11Forget it.
04:18It really does say Supercop.
04:20Have you got anywhere with that cipher in James' notebook?
04:23Anywhere at all?
04:27Great, good.
04:28So since you've been here, you've solved four murders and not a single letter of that thing.
04:32James is not cleverer than most murderers. Not to mention me.
04:35James is no cleverer than you. He never was. He's just much more...
04:40You know what I mean.
04:42Look, the cipher is a puzzle. Solving puzzles is literally what you do.
04:46But I need the source code.
04:48Well, work out what and where it is, then.
04:51But like it or not, you and James think in the same way.
04:54Where would you hide it?
04:56Probably in plain sight.
04:58Right, well, look there, then.
04:59OK.
05:01Can I get up now, please?
05:03Yes.
05:05I'm in my pyjamas.
05:14Do me a favour, John.
05:16Don't solve any murders today.
05:18I'll try really hard not to, I promise.
05:29Health and safety.
05:31Can't let you in without it.
05:32Right.
05:33There they work.
05:35Was he wearing one?
05:37Well...
05:44Gov.
05:46It's almost certainly a workplace accident.
05:48Let's just get it over with, get it passed on and get back to the station.
05:52Morning, Gov.
05:53Sir, Sergeant Finch is trying to access the CCTV.
05:56There are plenty of cameras dotted around the site.
05:59Now, staff-wise, there were only five others here at the time of the incident.
06:03I don't think that's quite right, sir. Do you mind if I...?
06:07Here, let me just...
06:08Don't twist it.
06:10Five, including you.
06:12Did you see it?
06:13No.
06:15But I heard it.
06:24Careful.
06:25Sorry, sir.
06:27Yes, Constable, I think the DCI can manage.
06:30Why don't you go and take some statements?
06:34And perhaps you can take us up to where he fell.
06:37Up?
06:39You scared of heights, Detective?
06:40Nobody's ever given me a good reason not to be.
06:48Running off a skeleton crew at the moment, at least for phase one.
06:51It's a budget thing.
06:52They promised me some more hands down the line.
06:54So who were the other four on site this morning?
06:57Well...
07:00That lot down there.
07:01I'm going to need a list of names.
07:03I'll give you the right one.
07:18Gary Jennings, he was on the mixers up here.
07:32Zara Bassett, OJ Turner, they were next floor up.
07:37Pretty much right below where he...
07:51Sorry, excuse me.
07:54That sign had a skull on it.
07:56What?
07:57Oh, yeah, yeah, don't worry about it.
07:58This platform's fine.
08:00I'm not actually sure why that was up here.
08:02It wasn't meant to be.
08:04And then there was Stefan, Polish kid.
08:07He got the worst of it.
08:09He hasn't been here that long.
08:13He actually saw it.
08:19What about the deceased?
08:20Martin Symes, what can you tell us?
08:22Marty, not a lot.
08:24He was a hard worker.
08:25Good laugh, bit of a lad, wind-up merchant, you know.
08:30Absolute tragedy.
08:32There you go.
08:33That's where he fell.
08:35What was he actually doing up here?
08:37Beats me.
08:38According to the rotor, nobody should have been.
08:41Well, the bolts have worked loose.
08:46I mean, he must have leant against it and...
08:52Well, it certainly looks like an accident, doesn't it?
08:54Good, agreed.
08:55Can we go back down now?
08:57What are you doing?
08:58Nothing, I was just...
09:00Looks like a fuse is blown on this thing.
09:02Looks like we haven't had enough setbacks already.
09:04More skulls.
09:05Why don't they just say no entry?
09:07Why do they have to be so graphic and portentous?
09:11Actually, that one's not meant to be up either.
09:13It isn't?
09:29Is everything alright?
09:33Can we please go back down now?
09:54Ah, there you are, sirs.
09:56Not much help, I'm afraid.
09:57Didn't catch the accident.
09:59This here is the last footage at around 6am.
10:01Nobody was even on site then.
10:03They're motion sensitive.
10:04Fox probably set it off.
10:15Listen, is this going to take much longer?
10:17Look, I know you've got a job to do, but so have we.
10:20I've got half a dozen workers out there, sat around doing nothing.
10:22Look, they're all shook up, but they want to work.
10:25And we're on a tight schedule.
10:28I'm afraid that's the least of your problems.
10:31What? What do you mean?
10:33Well, for a start, one of them is a murderer.
10:39So not an accident, are you sure?
10:41Absolutely.
10:42Well, there certainly were quite a few things that don't add up.
10:45Like the warning signs blocking various paths.
10:48They're missing from the CCTV earlier that morning,
10:51meaning someone must have put them up afterwards
10:53when there were only five people on the site,
10:55all of whom claim it wasn't them.
11:00Is that it?
11:02Well, yes.
11:04Oh, no, there's the generator thing up where he fell.
11:07That had been deliberately tampered with.
11:09Completely rewired.
11:11How do you know that?
11:12Well, you don't have to be a trained electrician
11:14to know that red goes in red, green goes in green,
11:16and blue goes in blue.
11:17This was all over the place.
11:19Red was in green, green was in orange.
11:21I don't even want to think about where blue was going.
11:26It was murder.
11:27Believe me, I wish it wasn't.
11:33Yes, well, I wish it wasn't too.
11:34You'll be tied up for days now.
11:36No, I won't.
11:37There's only five suspects, it shouldn't be hard.
11:40Goodness, that article really has gone to your head, hasn't it?
11:43Well, I mean, it's always nice to get positive feedback, but...
11:48Oh, no, that computer woman's here.
11:50What computer woman?
11:51Holly Pinder.
11:52She almost caught me this morning.
11:54What are you doing, what?
11:56Going through the Sinclair report.
12:13Shift, I need that computer.
12:15I need to install an update on it.
12:16In fact, I need to install updates on half the ones in the station,
12:19so if you don't mind.
12:21Just a second.
12:23Just a second.
12:34Wow.
12:36That must have been some serious porn you had on there.
12:43Are you laughing?
12:45No.
12:46Sorry.
12:47OK, good, because I don't think this woman likes me very much.
12:51Or James, anyway.
12:53She's always giving me funny looks
12:55and sarcastic answers to perfectly normal questions.
12:58Well, that could be a John thing rather than a James thing,
13:00and let's be honest,
13:01you've had funny looks and sarcastic responses all your life.
13:06Oh.
13:07No, I didn't mean that, I was just saying...
13:10No, no, it's fine, you're probably right.
13:14I'd better go.
13:21Look, I've nearly lost the day already.
13:23I'm not interested in any of that, OK?
13:25This happens to be a crime scene that you're busy cementing over
13:28and I'm ordering you to stop.
13:30You can't order me to do anything.
13:32Oh, she can. She's really good at it.
13:34Well, you are.
13:35Oh, here comes reinforcement.
13:37Look, this has already been cleared by your gaffer, all right?
13:40So you take out with him if you need to.
13:43Him, her, whatever.
13:45Listen, love, I've worked sites like this all my life
13:48and I've seen a million accidents like this one.
13:50And yet they keep employing you.
13:52What?
13:53You two, head back to the station, please.
13:55Sir.
13:57We need to talk to everyone that was on site this morning.
14:00We're not down in tools.
14:03Heaven forbid.
14:09Listen, love.
14:11I really hope you did it.
14:13It would bring me great pleasure to arrest that man.
14:15Yeah, but it's my turn, isn't it?
14:19You said it was my turn.
14:21What?
14:29This ain't coming off our brakes, is it?
14:31It's just a few questions.
14:34All right, well, you'd better get on with him then
14:36because it was obviously an accident.
14:38It's not something I want to talk about too much
14:40because it could have been any of us.
14:41It wasn't an accident.
14:42The foreman mentioned you.
14:44What is it you're saying?
14:45Do you think he was pushed or something?
14:47We certainly need to explore the possibility
14:49if only to shut it down.
14:50So a good place to start would be
14:52if either of you know of any reason
14:53someone might want to harm Marty.
14:55Aside from the fact that he was an arsehole, you mean?
14:57Christ, Z.
14:58Look, I wouldn't wish this on my worst enemy,
15:00but he was an arsehole.
15:02She used to get out of him.
15:03No, I didn't.
15:04I went on one date with him six months back
15:05because he wouldn't take no for an answer.
15:06I think it was a bit more than a date.
15:07Really? Is that what he told you all, is it?
15:09Like I say, arsehole.
15:13Look, you get it, all right?
15:14He was a bit of a lad.
15:15He worked hard, played hard.
15:17Just loved winding people up.
15:18He was harmless. It was all in good fun.
15:19Tell that to Stefan.
15:20Marty's idea of winding people up
15:22involved convincing them they were about to be deported.
15:25Stefan Kaminski?
15:26Yeah, yeah.
15:27Marty had been whacking over a load of emails to him
15:29saying he's from immigration,
15:30talking about work permits and that.
15:32That's Stefan completely convinced.
15:34Why on earth would he do that?
15:35For a laugh.
15:36No harm in it. It was a joke.
15:38How is it a joke?
15:39It doesn't follow any of the normal
15:41or traditional structures of a joke.
15:43Not as I've been led to understand them, anyway.
15:45I guess everything's a joke,
15:47as long as you're not the butt of it.
15:48And I'm guessing you never have been.
15:50Guess again.
15:51He once had me totally convinced
15:53that our syndicate had won the lottery.
15:55Made a ticket up and everything.
15:56I was this close to asking my girlfriend to marry me.
15:58It was a lucky escape.
16:00Yeah, tell him me.
16:01I meant for her.
16:02You see, that's a joke.
16:03You set up a false premise,
16:05then you subvert it.
16:09So when did you both get on site this morning?
16:11Seven-ish.
16:12For a 7.30 start.
16:13And did either of you see Marty?
16:15No.
16:16Well,
16:17not until it was too late.
16:20And what about you?
16:21Yeah, yeah, I saw him.
16:22I spoke to him.
16:23Look, I told you little Bobby this.
16:25The only reason I was on the mixer this morning
16:27is because Marty wanted to swap with me.
16:29I was meant to be on riveting.
16:30Wait a minute.
16:31Wait a minute.
16:32You're saying that you were supposed to be up there
16:33where he fell?
16:34No, riveting's on G5.
16:36That's F6.
16:37I don't think anyone's meant to be up there today.
16:38Sorry, G5, F6.
16:40Oh, the site's divided up into zones.
16:42There's always a rota up when we get here,
16:44but we often just chop and change between us.
16:48But if you're all always swapping around,
16:50how does anyone know what anybody else is doing?
16:52I've just become second nature.
16:54Instinctive.
16:55Yes, I see.
16:56Like ants.
16:57Excuse me?
16:58Well, in a nest or a hive
17:00where there are thousands of organisms...
17:02So, would either of you happen to know
17:03which zone we can locate Stefan in right now?
17:07Marty did apologise.
17:09Would you have made him?
17:11To be right, I did.
17:12Stefan here spent a solid week
17:14convinced he was being booted out of the country.
17:16I don't mind a joke, but this is a dangerous job.
17:19You don't want to be operating heavy machinery
17:21next to a guy with a head full of that sort of worry.
17:23And when exactly was this apology?
17:25Yesterday.
17:26End of shift.
17:28I said it was OK.
17:29Then was it?
17:30Doesn't matter now.
17:31No.
17:32I mean, nobody wanted this.
17:34Someone did.
17:38So, did either of you see him this morning?
17:41Yeah.
17:42I spoke to him first thing as it goes.
17:44We were both in early.
17:46He was whinging about the rotor.
17:48Wasn't happy with all the swaps he was going on.
17:50Although he still tried to swap with me.
17:53I said no.
17:54How about yourself?
17:55Did you speak to him?
17:56How about yourself?
17:57Did you speak to Marty at all this morning?
17:58No.
17:59I saw him now.
18:01Twice.
18:02First time was about ten minutes before the accident.
18:05I was on bricklaying.
18:07Tried to take a shortcut between E1 and H1.
18:10But there was a sign blocking my way.
18:13So I had to go find another way to get around.
18:15Marty was up on the third floor
18:17testing the new magic riveter, I think.
18:23So you say you saw him twice.
18:24When was the second time?
18:27Oh, yes, of course.
18:31I'm sorry.
18:32That must have been...
18:33It was.
18:34I've never seen another man die before.
18:37So sudden.
18:41One minute there was this empty space before me
18:46and then suddenly...
18:54Gav?
18:55Gav?
18:57Oh, sorry.
18:59What is this, please?
19:00What do you mean, what is it?
19:02It's a chute, isn't it?
19:03A chute, yes.
19:05Where does it go?
19:08It goes down.
19:13Are you going to fill me in on exactly what it is we're looking for here, Gav?
19:16Whatever's in it, of course.
19:19The top of it is right next to the crime scene itself.
19:23So it's possible...
19:24Look, do you think we could start calling it the incident location?
19:27Only I'm starting to think more and more...
19:29Aha, there.
19:30See, what do you call that?
19:34It's a plastic bottle.
19:36It's my water dispenser.
19:37There's several dotted around the site.
19:39Yes, but what's it doing in here?
19:42It's a skip.
19:43Traditionally, that's where you put rubbish
19:45like empty plastic bottles.
19:47Or perhaps it was a full plastic bottle when it was taken up there.
19:50Then an empty one when it was dropped down the chute.
19:53Someone poured it onto the generator.
19:55You must have noticed how wet the floor was.
19:57That could have been...
20:00You don't really expect to be able to move a two-tonne skip, do you, Gav?
20:04Well, I was going to give it a go.
20:07Oh, no.
20:09That's no good.
20:10That's no good at all.
20:14Gav, wait.
20:16Gav, wait.
20:17Wait, Gav.
20:19Hey, run, Forrest!
20:22Gav, I really do think we should entertain the possibility
20:25that this was an accident.
20:28Excuse me, where do you think you're taking that?
20:31That's evidence, isn't it?
20:32They can't take away evidence, can they?
20:34Evidence of what?
20:35It's a burnt-out generator, like I told you earlier.
20:38What are you doing?
20:39You've pulled all the wires out!
20:41Yeah, to move it.
20:42They're all in the wrong place anyway.
20:43Well, can you put them all back again, please?
20:45Put them back?
20:46In the wrong place?
20:48I get it, I'll do it.
20:50It is safe?
20:51Of course it's safe, it's completely dead.
21:00Of course he...
21:05He can't actually remember where each and every one of those wires went.
21:08Oh, believe me, he can.
21:14There.
21:15Are you a trained electrician?
21:17As a matter of fact, I am.
21:18Excellent.
21:19If this was wired like this and wasn't already dead,
21:22what would happen if you turned it on?
21:24Well, the fuse would blow.
21:26Which it did.
21:27And what would happen to the person who pressed the button?
21:29And let's assume, for the sake of argument,
21:31that the generator was wet at the time.
21:33I don't know.
21:34They'd get a very nasty shock, but it wouldn't kill them.
21:36Just knock them backwards, straight into a sink,
21:39that had already had several of its bolts deliberately worked loose.
21:54OK, then.
21:56I want that generator taken back off that truck.
21:58Listen, mate.
21:59No, you listen, mate.
22:00This is a crime scene.
22:01That is evident.
22:02It is not leaving this site,
22:03and you're going to come with the generator?
22:05No.
22:06That is evident.
22:07It is not leaving this site,
22:08and you're going to come with us and answer some questions.
22:11Understood?
22:17Gov?
22:31So this is everything from his locker?
22:33Yeah.
22:34No idea what's supposed to do with it all.
22:36Well, given your keenness to remove evidence from the scene,
22:39I'm surprised you didn't just chuck it.
22:42Oh, I see.
22:43So I do my job,
22:44arrange for a burnout generator to be replaced like it should be,
22:47and suddenly that makes me a suspect.
22:49You're a suspect because you're one of only five people
22:51who could have committed the murder.
22:58This is a Ludwig.
23:00A what?
23:01Hmm?
23:03He's a world-famous puzzle setter.
23:06Quite the legend in his field.
23:09These puzzles have all been done.
23:11Well, maybe some of the lads have been doing them on their break.
23:14Really?
23:15None of them seem very puzzle-solving.
23:18Sorry?
23:19All right, moving on.
23:20You said earlier you didn't think anybody was on site
23:22at 6am when the cameras went off.
23:25What time did you get here?
23:26Half past.
23:27Nobody else was here.
23:29Well, somebody was.
23:30Because somebody had spent the previous half hour
23:33setting up the Rube Goldbergian sequence of events
23:36that would eventually lead to Marty's death.
23:38Unless that somebody was you.
23:41What?
23:43I don't even know what a Ruby Golden whatever is.
23:47Have you ever played Mousetrap, the board game?
23:50Hasbro, 1963?
23:52No.
23:53Really?
23:54You've missed out.
24:01What's he...?
24:03Don't worry about him.
24:04So, who was the first person to arrive after you?
24:08I actually think it was Marty.
24:10But I didn't speak to him.
24:11I was on a call.
24:13At 6.30 in the morning?
24:16I was checking out flights, if you must, though.
24:19Look, it's got nothing to do with your investigation,
24:22so I would appreciate if you kept this to yourself.
24:25I've been offered an interview for a new job
24:29overseeing the construction of a luxury hotel abroad.
24:33Abroad where?
24:34Las Vegas.
24:35I shouldn't have thought so.
24:36I suspect that was just a joke.
24:40A joke?
24:41Yes, people are quite cavalier with the definition of that word here.
24:45Email, was it?
24:47Does rather fit Marty's MO, I'm afraid.
24:52A joke?
24:53Yes.
24:54Unfortunately for you, one that gives you a motive.
24:57Although, unfortunately for us, it's the same motive as everyone else,
25:01which is very inconvenient.
25:03What motive? What are you talking about?
25:04I believe one of your employees summed it up earlier.
25:07Marty was an A triple asterisk hole.
25:11This whole rotor thing of yours is ludicrous.
25:14How does anyone make head or tail of it?
25:16You've got someone who's supposed to be on G4 going to H1,
25:21someone who's meant to be at C3 going to F6,
25:24and someone from A1 who's gone so far down the alphabet,
25:26I'm surprised the zone's not in hieroglyphics.
25:29Let me ask you something.
25:30Is there a single person that works on this site
25:33who is ever where they're supposed to be?
25:35Doesn't look like it, sir, no.
25:38They chop and swap at will.
25:40No rhyme nor reason to it.
25:42Madness.
25:44Right, I've got it open.
25:46I've gone right through it.
25:47This guy had a lot of email accounts, all under different names.
25:51I found your deportation papers one.
25:53And the fictitious Vegas job.
25:55I then did a data mine on all his social media.
25:58He had a lot of accounts there too, but none in his own profile.
26:01Some are men, some are women.
26:03All the photos have been nipped from somewhere else
26:05and all the names have been made up.
26:07He was a catfish.
26:11You do know what a catfish is, don't you, sir?
26:14I think you and everyone else here knows full well
26:17that I'm about to state incorrectly that it's a type of fish.
26:20Well, it's someone who pretends to be someone they're not.
26:24I'm going to go through all the accounts he's targeted
26:27and see if any more of your suspects are amongst them.
26:31Thank you, Holly.
26:33Gov, do you want to...?
26:35Hmm?
26:37Gov?
26:38Oh, er, yes.
26:40So, the murder was surprisingly well planned, considering.
26:45But there was still a fair amount of evidence left behind
26:49the rewired generator, the pool of water, the loosened bolts.
26:54And who's all this evidence pointing to, sir?
26:56I don't know yet.
26:58So how is the evidence?
26:59Sergeant Finch, is there something you'd like to get off your chest?
27:02Yes, please.
27:04May I? Thank you.
27:06OK, correct me if I'm wrong, sir,
27:08but presumably your theory is that the killer set this death trap up
27:11on the fourth story and then manipulated or coaxed the victim
27:14into walking into it.
27:15Yes, that's right.
27:16Ah, I was...
27:19No, well done, Liz.
27:21So how did they guarantee that nobody else would walk into it first?
27:24Our killer wouldn't just have to manipulate the victim,
27:27they'd have to manipulate the movements of every single other person
27:30on the site too.
27:31Is that even possible?
27:33Of course it's possible.
27:35Well, it is possible, isn't it, Gov?
27:37It's possible, yes.
27:40But presuming that our killer was someone of very high intelligence.
27:45Well, they'd have to be a genius.

33:11Who with?
33:15Oh, I see.
33:17Not that we really played it together.
33:19He'd just sort of come in while I was asleep and move a piece.
33:23I'd wake up the next day, move another.
33:26Which side are you?
33:27Black.
33:28So your last move was knight to queen one?
33:33Yeah.
33:36How did you know that?
33:38It's difficult to explain.
33:40It's a type of puzzle called reverse chess.
33:44I invented it, actually.
33:46You're presented with a board in the middle of the game,
33:49but instead of having to work out what comes next,
33:52you use maths, probability and reason to deduce what came before.
33:57I didn't really catch on.
33:59Nobody could ever solve them.
34:04Oh.
34:07Your mother is crying in the kitchen.

34:24That and mousetrap.
34:26Is she crying because of me?
34:28No.
34:29Not because of me.
34:32She's crying because she's frustrated, scared
34:35and the person she wants to take it all out on isn't here.
34:40I expect you can relate to that.
34:52Mum?
34:54Henry, please don't. I can't go another round.
35:01I'm sorry.
35:05You have nothing to be sorry for.
35:11Neither do you.
35:25Don't get used to it.
35:31I love you.
36:01Right then, let's start with one central and indisputable fact.
36:27This wasn't an accident.
36:29This was a murder.
36:31And an especially ingenious one at that.
36:34So, well done.
36:37Marty Symes was led to his death by a series of supposedly impromptu rotor swaps
36:43guaranteeing that he would be the one to end up by the generator.
36:48And the genius of it all, and it was genius,
36:51was that the killer's manipulation of all your movements was tertiary at best.
36:56Most of you were inadvertently manipulating each other.
36:59The killer, with an impressive level of psychological insight,
37:03accurately predicted who would swap with who and in what order,
37:08leaving his or her own machinations hidden.
37:13If it helps, I've prepared a practical demonstration, I think.
37:18Counsellor Evans, did you...
37:21Yes, sir.
37:24Excellent. Now, if all this is starting to sound like a game,
37:28that's because, in essence, it was. You were all pawns.
37:32And by happy coincidence, your impractical grid system here
37:37contains exactly the same number of squares as...
37:42What is this?
37:44Well, it's a chess set, sir.
37:47I had to go to the garage, that's all they had.
37:55They had loads of connect force.
37:57We'll keep that in mind for any future cases, Constable.
38:06My little girl's got that set.
38:10Cool.
38:13Right, then. You should like this.
38:16It's a criminally underappreciated form of puzzle known as reverse chess.
38:20We start with the end game and we work backwards.
38:24Marty Syme's last move was to F6, i.e. the crime scene.
38:29The rest of you, you wound up in these spaces,
38:32where not one of you was meant to be.
38:35Meaning that the game had already been played without any of you knowing.
38:39So let's play it again, shall we?
38:42Backwards.
38:45Marty found himself up in F6 because the riveter in G5 had no power.
38:51But he was only in G5 because he'd swapped with Gary from C3.
38:56And Gary only wound up in G5 because he'd swapped with OJ from F4.
39:03Which should have left Gary here with Stefan in G4,
39:08except OJ had asked Stefan to swap with Zara in H1.
39:13Which leads us to the only move that really counts.
39:17The first one.
39:19The one that started the sequence of events that eventually led to Marty heading off to the pneumatic riveter.
39:25A pneumatic riveter that was itself powered by a generator on the fourth story.
39:30Or rather, in this instance, not being powered by it.
39:34Which, of course, was further manipulation by the killer,
39:38designed to move their target one story higher
39:42to what my colleagues colourfully referred to as a death trap.
39:49A generator that had been deliberately rewired,
39:52railing bolts that had been surreptitiously loosened,
39:55and an 18 litre bottle of water that had been poured out around the base of the generator
40:00and then disposed of down the nearby chute.
40:02And the rest, as they say, is tragedy.
40:10And all from just one move.
40:14The opening gambit.
40:17Yours.
40:18Wait, what?
40:21You don't think I had anything to do with this?
40:25Of course not. You were just the first piece to move, that's all.
40:29But it wasn't your hand that moved it.
40:33Was it?
40:37You were meant to be in H1.
40:41You did swap with me.
40:43Insisted on it, I would wager.
40:50So?
41:06Look, I ain't going to pretend like I followed a word of that, mate.
41:09But what I am going to ask is why the hell I'd want to kill Marty.
41:14Quite why anybody ever wants to kill anyone is a mystery to me.
41:18I've certainly never wanted to.
41:21But since you ask, I'm going to go with pride and arrogance.
41:26I do believe that you took the joke of the lottery win in your stride,
41:30even if you embarrass yourself slightly, by proposing to your girlfriend as a result.
41:35Almost proposing to my girlfriend.
41:37No, actually proposing. Our computer woman has seen the messages.
41:41I was wondering, though, when exactly did you discover that you never even had a girlfriend?
41:48That it had just been Marty all along?
41:51We've had all the IPs traced. We know you were one of Marty's catfish victims.
41:55Even though you were using a fake profile and photo yourself?
41:58Yes. Ironically, you thought you were catfishing her.
42:04In fairness, making the joke a lot more layered than I gave it credit for.
42:09OK, well, if you must know, I caught a glimpse of his phone on a break. Saw the profile.
42:14So what? He was pranking me while I was pranking him.
42:17There's no reason to murder, is there?
42:19Not for a normal person, no. But you're not a normal person, are you?
42:23You're a man of enviable intellect who hides it all behind spitting and saying mate a lot.
42:29A man who couldn't bear to be beaten by someone so much stupider than him.
42:35That's it? That's my motive? That's the motive of a complete sociopath?
42:42Yes. It is.
42:44Right, you're going to bring this little chess set to trial with you, are you?
42:47Oh, no. We've got some actual real evidence to go along with it.
42:51The water bottle that you disposed of down the chute was tested for DNA.
42:55Sergeant Finch got the results back this morning, didn't you, Sergeant?
42:58Yes, sir. It's a match.
43:01It's a match.
43:02Oh, right. What was that then?
43:04The bottle I took from that drink dispenser over there?
43:06The empty one that I tucked in the skit?
43:08From the fourth story, via the chute.
43:10No, mate. From the ground, via my hands.
43:13Never even been up to F6. Not once.
43:17Your move.
43:20My move?
43:24Yes.
43:32Well, come on, then.
43:45Right, then. Dispose of this for me, will you?
44:02You don't really expect to be able to move a two-tonne skip, do you?
44:08I thought I'd give it a go.

45:01You do not have to say anything, but it may harm your defence
45:04if you do not mention when questioned something which you later rely on in court.
45:28Yes, sir.
45:30Yes, sir.
45:33Signed, confession. Case closed.
45:38It was DCI Taylor.
45:42I can assure you that's no longer an issue.
45:46Yes, sir.
45:49I can assure you that's no longer an issue.

46:22Nothing.
46:23You know, it's the craziest thing.
46:25I've been doing a security sweep on all the systems,
46:28and do you know what I found?
46:30Chief Constable Ziegler has been accessing a lot of files lately
46:34from your computer.
46:36Even on the days he's not been there.
46:38So how do you suppose he did that?
46:41Don't worry. I've wiped the system.
46:44Don't worry. I've wiped the system.
46:47Why would you do that?
46:49Dunno.
46:51I won't do it again.
47:15Knock, knock.
47:26Hello.
47:32Oh, dear. What's the matter?
47:35The computer woman knows what I've been doing.
47:38What?
47:39Using Ziegler's login.
47:41Accessing files I shouldn't be.
47:43But she's covered it up.
47:45Wiped it all from the computers.
47:47So what does that mean? Is she a goody or a baddy?
47:49I don't know.
47:51But I'm going to find out.
47:53What's all that?
47:55It's for the cipher. I've already made a start.
47:57I'm going through it all page by page, book by book,
48:00night after night if I have to, no matter how long it takes.
48:03You haven't given up, then?
48:05Of course not. Why would I?
48:07I'm really good at this. Don't you read the paper?
48:11Right. Speaking of homework...
