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.
00:20Name was Mandy Ziegler.
00:23As in?
00:24He had the fast track transfer.
00:26That's all I've ever asked of him.
00:27Another Sinclair case is Roger Sinclair.
00:31Single man disturbed a burglar who killed him in a 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.
01:03It's too much.
01:04It's too big.
01:56Oh, no!
01:57Oh, no!
01:58Oh, no!
01:59Oh, no!
02:00Oh, no!
02:01Oh, no!
02:02Oh, no!
02:03Oh, no!
02:04Oh, no!
02:05Oh, no!
02:06Oh, no!
02:07Oh, no!
02:08Oh, no!
02:09Oh, no!
02:10Oh, no!
02:11Oh, no!
02:12Oh, no!
02:13Oh, no!
02:14Oh, no!
02:15Oh, no!
02:16Oh, no!
02:17Oh, no!
02:18Oh, no!
02:19Oh, no!
02:20Oh, no!
02:21Oh, no!
02:22Oh, no!
02:23Oh, no!
02:24Oh, no!
02:25Oh, no!
02:26Oh, no!
02:27Oh, no!
02:28Oh, no!
02:29Oh, no!
02:30Oh, no!
02:31Oh, no!
02:32Oh, no!
02:33Oh, no!
02:34Oh, no!
02:35Oh, no!
02:36Oh, no!
02:37Oh, no!
02:38Oh, no!
02:39Oh, no!
02:40Oh, no!
02:41Oh, no!
02:42Oh, no!
02:43Oh, no!
02:44Oh, no!
02:45Oh, no!
02:46Oh, no!
02:47Oh, no!
02:48Oh, no!
02:49Oh, no!
02:50Oh, no!
02:51Oh, no!
02:52Oh, no!
02:53Congratulations, page five.
03:08That's me.
03:09Not according to that it isn't. According to that, it's Supercop DCI James Taylor.
03:14Supercop? Is that what it says?
03:16What on earth were you thinking?
03:19How's this my fault? I 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? A fan?
03:35Because you can't go plastering yourself 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.
03:48Oh, 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. So since you've been here, you've solved four murders and not a single letter of that thing.
04:31James 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.
04:41Look, the cipher is a puzzle. Solving puzzles is literally what you do.
04:46But I need the source code.
04:48We'll work out what and where it is then.
04:50But like it or not, you and James think in the same way. Where would you hide it?
04:55Probably in plain sight.
04:57Right, well look there then.
04:59OK.
05:01Can I get up now, please?
05:03Yes.
05:05I'm in my pyjamas.
05:13Do me a favour, John.
05:15Don't solve any murders today.
05:17I'll try really hard not to, I promise.
05:28Health and safety. Can't let you in without it.
05:31Right. Do they work?
05:34Was he wearing one?
05:36Well...
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.
05:59Staff-wise, there were only five others here at the time of the incident.
06:03I don't think that's quite right, sir.
06:05Do you mind if I...?
06:06Here, let me just...
06:07Let me just...
06:08Don't twist it.
06:09Five, including you.
06:11Did you see it?
06:13No.
06:14But I heard it.
06:23Careful.
06:24Ow!
06:25Sorry, sir.
06:26Yes, yes, 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?
06:38You scared of heights, Detective?
06:40Nobody's ever given me a good reason not to be.
06:47Running off a skeleton crew at the moment, at least for phase one.
06:50It's a budget thing.
06:51They promised me some more hands down the line.
06:53So who were the other four on site this morning?
06:56Er... Well...
06:59What's that lot down there?
07:01I'm going to need a list of names.
07:03I can give you the right one.
07:17Gary Jennings, he was on the mixers up here.
07:31Zara Bassett, OJ Turner, they were next floor up.
07:35Pretty much right below where we, er...
07:50Sorry, excuse me.
07:52That sign had a skull on it.
07:55What?
07:56Oh, yeah, yeah, don't worry about it. This platform's fine.
07:59I'm not actually sure why that was up here. It wasn't meant to be.
08:03And then there was Stefan, Polish kid.
08:06He got the worst of it.
08:08He hasn't been here that long.
08:12He actually saw it.
08:18What about the deceased, Martin Symes? What can you tell us?
08:21Marty? Not a lot.
08:23He was a hard worker. Good laugh.
08:25Bit of a lad, wind-up merchant, you know.
08:29Absolute tragedy.
08:31There you go. That's where he fell.
08:35What was he actually doing up here?
08:37Beats me. According to the rota, nobody should have been.
08:41Well, the bolts have worked loose.
08:45I mean, he must have leant against it and...
08:51Well, it certainly looks like an accident, doesn't it?
08:54Good! Agreed. Can we go back down now?
08:56What are you doing? Nothing. I was just...
08:59Looks like a fuse has blown on this thing.
09:01Like we haven't had enough setbacks already.
09:03More skulls. Why didn't they just say no entry?
09:06Why do they have to be so graphic and portentous?
09:10Actually, that one's not meant to be up either.
09:12It isn't?
09:27Gabi, is everything all right?
09:32Can we please go back down now?
09:53Ah, there you are, sirs.
09:55Not much help, I'm afraid. Didn't catch the accident.
09:58This here is the last footage at around 6am.
10:00Nobody was even on site then.
10:02They're motion sensitive. Fox probably set it off.
10:14Listen, is this going to take much longer?
10:16Look, I know you've got a job to do, but so have we.
10:19I'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, completely 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 and blue goes in blue.
11:17This was all over the place.
11:18Red was in green, green was in orange.
11:20I don't even want to think about where blue was going.
11:25It was murder. Believe me, I wish it wasn't.
11:32Yes, well, I wish it wasn't too. You'll be tied up for days now.
11:35No, I won't. There's only five suspects. It shouldn't be hard.
11:39Goodness, that article really has gone to your head, hasn't it?
11:42Well, 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. She almost caught me this morning.
11:55What are you doing what?
11:56Going through the Sinclair report.
12:13Shift, I need that computer. I 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. Just a second.
12:34Wow.
12:36That must have been some serious porn you had on there.
12:41SHE LAUGHS
12:43Are you laughing? No.
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 and sarcastic answers
12:56to perfectly normal questions.
12:58Well, that could be a John thing rather than a James thing,
13:00and let's be honest, you'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. You can't order me to do anything.
13:31Oh, she can. She's really good at it.
13:33Well, you are.
13:35Oh, here comes reinforcement.
13:37Look, this has already been cleared by your gaffer, all right?
13:40You take up with him if you need to.
13:42Her.
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,
14:00or we're not down in tools.
14:04Heaven forbid.
14:06Listen, love...
14:08I really hope he did it.
14:10It would bring me great pleasure to arrest that man.
14:12Yeah, but it's my turn, isn't it?
14:16You said it was my turn.
14:18What?
14:27This ain't coming off our brakes, is it?
14:29It's just a few questions.
14:31All right, we'll see you later.
14:34All right, well, you'd better get on with him then,
14:36because it was obviously an accident.
14:38It's not something we 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.
14:43What is it you're saying?
14:44Do you think he was pushed or something?
14:46We certainly need to explore the possibility,
14:48if only to shut it down.
14:50So a good place to start would be,
14:51if either of you know of any reason someone might want to harm Marty...
14:54Aside from the fact that he was an arsehole, you mean?
14:56I see.
14:57Look, I wouldn't wish this on my worst enemy,
15:00but he was an arsehole.
15:01She used to go out with him.
15:02No, I didn't.
15:03I went on one date with him six months back,
15:05cos 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'd been whacking over a load of emails to him,
15:29saying he's from immigration,
15:31talking about work permits and that.
15:32Had Stefan completely convinced.
15:34Why on earth would he do that?
15:35For love.
15:37No harm in it. It was a joke.
15:38How is it a joke?
15:40It doesn't follow any of the normal
15:42or traditional structures of a joke.
15:44Not as I've been led to understand them, anyway.
15:46I guess everything's a joke,
15:48as long as you're not the butt of it.
15:49And I'm guessing you never have been?
15:51Guess again.
15:52He once had me totally convinced
15:54that our syndicate had won the lottery.
15:56Made a ticket up and everything.
15:57I was this close to asking my girlfriend to marry me.
15:59It was a lucky escape.
16:01Yeah, tell him me.
16:02I meant for her.
16:03You see, that's a joke.
16:04You set up a false premise, then you subvert it.
16:10So when did you both get on site this morning?
16:12Seven-ish, for a 7.30 start.
16:14And did either of you see Marty?
16:16No.
16:17Well, not until it was too late.
16:21And what about you?
16:22Yeah, yeah, I saw him.
16:23I spoke to him.
16:24Look, I told your little Bobby this.
16:27The only reason I was on the mixer this morning
16:28is because Marty wanted to swap with me.
16:30I was meant to be on riveting.
16:31Wait a minute.
16:32You're saying that you were supposed to be up there,
16:34where he fell?
16:35No, riveting's on G5.
16:36That's F6.
16:37I don't think anyone was meant to be up there today.
16:39Sorry, G5, F6.
16:41The site's divided up into zones.
16:43There'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.
17:10Would you have made him?
17:11To your right, I did.
17:13Stefan here spent a solid week
17:14convinced he was being booted out 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.
17:29I said it was OK.
17:30Then was it?
17:31Doesn't matter now.
17:32Nah.
17:33I mean, nobody wanted this.
17:35Someone did.
17:38So, did either of you see him this morning?
17:42Yeah.
17:43I spoke to him first thing as it goes.
17:45We were both in early.
17:47He was whinging about the rota.
17:49Wasn't happy with all the swaps he was going on.
17:51Although he still tried to swap with me.
17:54I said no.
17:55How about yourself?
17:56Did you speak to Marty at all this morning?
17:58No.
17:59I saw him, no.
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.
18:22So you say you saw him twice.
18:24When was the second time?
18:29Oh, yes, of course.
18:31I'm sorry.
18:32That must have been...
18:33It was.
18:34I'd never seen another man die before.
18:36So...
18:38sudden.
18:40One minute there was this...
18:43empty space before me and...
18:47then suddenly...
18:52Uh, Gov?
18:53Gov!
18:55Oh, sorry.
18:57What is this, please?
18:59What do you mean, what is it?
19:00It's a chute, isn't it?
19:01A chute, yes.
19:03Where does it go?
19:06It goes down.
19:11You going to fill me in on exactly what it is we're looking for here, Gov?
19:14Whatever's in it, of course.
19:21The top of it is right next to the crime scene itself.
19:24So it's possible...
19:25Look, do you think we could start calling it the incident location?
19:28Only I'm starting to think more and more...
19:30Aha! There!
19:31See, what do you call that?
19:35It's a plastic bottle.
19:37It's my water dispenser.
19:38There's several dotted around the site.
19:40Yes, but what's it doing in here?
19:43It's a skip.
19:45Traditionally, that's where you put rubbish, like empty plastic bottles.
19:49Or perhaps it was a full plastic bottle when it was taken up there.
19:52Then an empty one when it was dropped down the chute.
19:55Someone poured it onto the generator.
19:57You must have noticed how wet the floor was.
19:59That could have been...
20:02You don't really expect to be able to move a two-ton skip, do you, Gov?
20:06Well, I was going to give it a go.
20:09Oh, no.
20:11That's no good.
20:12That's no good at all!
20:15Gov, wait! Wait, Gov!
20:18Hey! Run, Forrest!
20:22Gov, I really do think we should entertain the possibility that this was an accident.
20:27Excuse me, where do you think you're taking that?
20:30That's evidence, isn't it?
20:32They can't take away evidence, can they?
20:34Evidence of what? It's a burn-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. They're all in the wrong place anyway.
20:43Well, can you put them all back again, please?
20:45Put them back? In 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. Are you a trained electrician?
21:17As a matter of fact, I am.
21:18Excellent. If 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. Which it did.
21:26And what would happen to the person who pressed the button?
21:29And let's assume, for the sake of argument, that the generator was wet at the time.
21:32I don't know. They'd get a very nasty shock, but it wouldn't kill them.
21:36Just knock them backwards, straight into a sink,
21:40Just knock them backwards, straight into a safety rail
21:43that had already had several of its bolts deliberately worked loose.
21:58OK, then.
22:00I want that generator taken back off that truck.
22:03Listen, mate.
22:04No, you listen, mate. This is a crime scene. That is evident.
22:06It is not leaving this site, and you're going to come with us
22:09and answer some questions. Understood?
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, arrange 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 who 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 at 6am when the cameras went off.
23:25What time did you get here?
23:26Half past. Nobody 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...?
24:02Don't worry about him.
24:03So, who was the first person to arrive after you?
24:07I actually think it was Marty.
24:09But I didn't speak to him.
24:10I was on a call.
24:11At 6.30 in the morning?
24:14I was checking out flights, if you must, though.
24:17Look, it's got nothing to do with your investigation,
24:20so I would appreciate if you kept this to yourself.
24:24I've been offered an interview for a new job
24:26overseeing the construction of the Rube Goldbergian sequence.
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, no 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, and 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.
26:21Well, it's someone who pretends to be someone they're not.
26:25I'm going to go through all the accounts he's targeted
26:28and see if any more of your suspects are amongst them.
26:32Thank you, Holly.
26:34Gov, do you want to...?
26:36Hmm?
26:38Gov?
26:39Oh, er, yes.
26:41So, the murder was surprisingly well planned, considering,
26:46but there was still a fair amount of evidence left behind.
26:50The rewired generator, the pool of water, the loosened bolts.
26:55And who is all this evidence pointing to, sir?
26:57I don't know yet.
26:58So how is the evidence?
27:00Sergeant Finch, is there something you'd like to get off your chest?
27:03Yes, please.
27:05May I? Thank you.
27:07OK, correct me if I'm wrong, sir,
27:09but presumably your theory is that the killer set this death trap up
27:12on the fourth story and then manipulated or coaxed the victim
27:15into walking into it.
27:16Yes, that's right.
27:17Ah, I was...
27:19No, well done.
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.
27:35Oh, it is possible, isn't it, Gov?
27:37It's possible, yes.
27:40But presuming that our killer was someone of very high intelligence.
27:45Oh, they'd have to be a genius.
27:49Gov?
27:55Gov?
27:59Could it all just be a coincidence?
28:03Could what all just be a coincidence?
28:05Is it possible that it really was just an accident?
28:09What? What are you talking about?
28:11You know it wasn't.
28:13Gov?
28:15You know it wasn't.
28:19Gov?
28:35Light, light, light, light!
28:38No, I'm not asking you to...
28:39Off, turn it off, turn it off!
28:43You can't just walk in here, you know that.
28:46The sign wasn't up.
28:47I thought that you were out all day.
28:49I was.
28:50It's nearly five.
28:51Is it?
28:52Yes, it is.
28:54Have you heard anything?
28:56Heard anything?
28:57From Dad.
28:59The article in the paper.
29:01Oh, no, I doubt your father...
29:02So you haven't heard anything?
29:05I would have told you if I had.
29:06Would you?
29:10You never told me that you left.
29:12I thought we'd had this conversation.
29:14I'm sensing that you have had a bad day.
29:16You are not the only one.
29:18It will all be okay.
29:20Your Uncle John...
29:21He is not my dad.
29:24You might be able to pretend that he is,
29:26sitting there on the bed reading the paper together,
29:29but I can't.
29:31Go to your room.
29:32Come on, Mum.
29:33I'm 15, you can't just...
29:35I said go to your room.
29:46Come on.
30:17Hi.
30:18Have you been crying?
30:21No.
30:22Allergies.
30:23What are you allergic to?
30:26Life.
30:27Yes, me too.
30:32Fine, we'll worry about you then, shall we?
30:34What if I can't solve the cipher?
30:36What if I actually can't do any of this?
30:38James is cleverer than me.
30:40He always has been.
30:41He's always been better than me.
30:43He always has been.
30:44He's always been better than me at everything.
30:47John, has something happened?
30:50This building site murder...
30:54I can't solve it.
30:56It seemed planned,
30:58but also sloppy.
31:00Evidence everywhere,
31:02indicating that it wasn't an accident.
31:04But that was no mistake.
31:06They just didn't care,
31:07because they knew I could never prove it.
31:09It's a game to them.
31:11They're just laughing at me.
31:14Like they always did.
31:16Always did?
31:17Yes.
31:18They're just a grown-up version
31:20of all the kids that would bully me at the bus stop.
31:24Nothing's changed.
31:27John, what are you trying to say?
31:30I'm trying to say that I'm not the smartest guy in the room.
31:33I'm not even the smartest guy in a building site.
31:36So who am I?
31:37Well, a bit of a snob, judging by that last comment.
31:40But apart from that,
31:41you are someone completely untrained
31:43who's just solved several murders without batting an eye.
31:46Perhaps I just got lucky.
31:47You don't believe in luck.
31:49You're the only person to have ever found a four-leaf clover
31:52and not even want it.
31:53The four-leaf clover?
31:55You remember that?
31:59Vaguely.
32:00I gave it to you in the end.
32:04You were going to laminate it and keep it forever.
32:07Yes, well, I was a sentimental idiot back then.
32:10Don't say it like that. You still are.
32:16You're welcome.
32:38Oh, it's just you.
32:40What's up?
32:42I think your mum is cross with me.
32:44Yeah, I think she's cross with me, too.
32:47I highly doubt that.
32:54Don't touch that.
32:56Sorry.
32:57It's fine.
32:58It's fine.
32:59It's fine.
33:00It's fine.
33:01It's fine.
33:02It's fine.
33:03It's fine.
33:04It's fine.
33:05It's fine.
33:06Sorry.
33:07I'm just... I'm in the middle of a game.
33:10Who with?
33:14Oh, I see.
33:16Not that we really played it together.
33:18He'd just sort of come in while I was asleep and move a piece.
33:22I'd wake up the next day, move another.
33:25Which side are you?
33:26Black.
33:27So your last move was knight to queen one?
33:33Yeah.
33:36How did you know that?
33:37It's difficult to explain.
33:39It's a type of puzzle called reverse chess.
33:43I invented it, actually.
33:45You're presented with a board in the middle of the game,
33:48but instead of having to work out what comes next,
33:51you use maths, probability and reason to deduce what came before.
33:56I didn't really catch on.
33:58Nobody could ever solve them.
34:07Your mother is crying in the kitchen.
34:10What?
34:12And you've just left her there?
34:14I'm not good at dealing with that sort of thing.
34:17Chess, on the other hand, I've always been good at that.
34:20One game I could always beat your dad at.
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.
34:53Mum.
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.
35:35Don't get used to it.
36:05Don't get used to it.
36:23Right then, let's start with one central and indisputable fact.
36:27This wasn't an accident.
36:29This was a murder.
36:32And an especially ingenious one at that.
36:35So, well done.
36:37Marty Symes was led to his death
36:40by 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
36:54was 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,
37:06and in what order, leaving his or her own machinations hidden.
37:13If it helps, I've prepared a practical demonstration, I think.
37:18Counsellor Evans, did you...?
37:20Oh, yes, sir.
37:24Excellent.
37:25Now, if all this is starting to sound like a game,
37:28that's because, in essence, it was.
37:30You 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?
37:44It's a chess set, sir.
37:46Had 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.
38:13Right, then. You should like this.
38:15It'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.
38:40So 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,
39:07except 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.
39:52Grailing 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?
40:23You 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.
40:49So?
41:05Look, I ain't going to pretend like I followed a word of that, mate.
41:08But what I am going to ask is why the hell I'd want to kill Marty.
41:13Quite why anybody ever wants to kill anyone is a mystery to me.
41:18I've certainly never wanted to.
41:20But since you ask, I'm going to go with pride and arrogance.
41:25I 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.
42:03In 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.
42:13Saw the profile. So 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?
42:41Yes. It is.
42:44Right, you going to bring this little chess set to trial with you, are you?
42:48Oh, 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.
42:56Sergeant Finch got the results back this morning, didn't you, Sergeant?
42:59Yes, 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.
43:47Right, then. Dispose of this for me, will you?
43:52You don't really expect to be able to move a two-tonne skit, do you?
43:59Thought I'd give it a go.
44:01No, I don't think you would be able to.
44:05Well, I would, but...
44:07You don't really expect to be able to move a two-ton skip, do you?
44:17I thought I'd give it a go.
44:21Congratulations, Detective.
44:24I appreciate that.
44:26Checkmate.
44:27I believe this is yours.
44:37I signed it for you.
44:47Answer the ball.
44:48Oi!
44:49That's not the foreman, though, is it?
44:52What?
44:53Oh, no, it's just that...
44:54It was supposed to be my turn.
44:57Gary Jennings, I'm arresting you on suspicion of murder.
45:03You do not have to say anything, but it may harm your defence if you do not mention when
45:06questioned something which you later rely on in court.
45:13Yes, sir.
45:19Yes, sir.
45:25Signed, confession.
45:31Case closed.
45:37It was DCI Taylor.
45:49I can assure you that's no longer an issue.
45:53Yes, sir.
46:19What have you got there, then?
46:25Nothing.
46:26You know, it's the craziest thing.
46:28I've been doing a security sweep on all the systems, and do you know what I found?
46:32Chief Constable Ziegler has been accessing a lot of files lately from your computer.
46:38Even on the days he's not been there.
46:40So how do you suppose he did that?
46:44Don't worry.
46:45I've wiped the system.
46:48Why would you do that?
46:49I don't know.
46:51I won't do it again.
47:18Hello.
47:26Oh, dear.
47:32What's the matter?
47:34The computer woman knows what I've been doing.
47:37What?
47:38Using Ziegler's login, accessing files I shouldn't be, but she's covered it up.
47:45Well, wiped it all from the computers.
47:47So what does that mean?
47:48Is she a goody or a baddy?
47:49I don't know, but I'm going to find out.
47:53What's all that?
47:55It's for the cipher.
47:56I've already made a start.
47:57I'm going through it all page by page, book by book, night after night if I have to, no matter how long it takes.
48:03You haven't given up, then?
48:05Of course not.
48:06Why would I?
48:07I'm really good at this.
48:08Don't you read the paper?
48:11Right.
48:12Speaking of homework.
48:14Good lad.
48:16Homework, my arse.
48:23Do you fancy taking an hour off?
48:25We could watch a film.
48:26You can choose.
48:29I'm all right, thanks.
49:30Hello?
49:34Hello?
49:38Hello?
49:42Hello?
49:46Hello?
49:50Hello?
49:54Hello?
49:59Hello?
50:02What do you think you're playing at?
50:05I'm not sure.
50:07I saw you in the paper.
50:09Why are you back there?
50:11What the hell do you think you're doing?
50:15James?
50:16I'm sorry, it's a really bad line.
50:19I...
50:21Who is this?
50:46Come in.
50:50James just got a funny phone call from a funny phone number.
50:54Who was it?
50:55Was it him?
50:56No, it was some man.
50:58What did he say?
50:59Sorry, what are you doing?
51:01You're in your, you know, nightie.
51:05Why don't I get up and you go and make us both a coffee?
51:11What's going on?
51:12What's happened?
51:13Somebody's called.
51:14It wasn't Dad.
51:15I'm sure it's nothing to worry about.
51:16I'm going back to bed.
51:21John, you better make that three coffees.
51:47I'm sorry.
51:48I'm sorry.
51:49I'm sorry.
51:50I'm sorry.
