James didn't just vanish.

He left breadcrumbs, coded messages, a puzzle.

I didn't want to see DI Neville transferred any more than you did

but, after all that Sinclair business, there was no other option.

I'm looking for Matt Neville.

He lives here.

He did. Moved out a month ago.

The first page has been torn out.

"Sinclair". And look at the bottom.

"Zieg R".

Roger Sinclair, disturbed a burglar who then killed him

in a panic of self-preservation.

Something has changed.

There's even an arrest!

And look who signed off this one.

DCI Taylor.

Ah!

Sh.

Can you hear that?

Woo!

The acoustics in here are...

Do we have any opera singers amongst us that

maybe want to try hitting the...

Right, come on. This way.

The actual date of construction is unknown, of course -

it's not called the Dark Ages for no reason.

Speaking of which, why is this curtain closed?

OK, you're going to love this next bit.

Nobody knows if it's an architectural fluke

or God's own design, but every afternoon the sun hits

the stained-glass windows hidden behind those curtains,

and this entire place is treated to a light-show

that would put a disco to shame.

THEY MUTTER

Argh!

ZIPPING

Do you know who she was?

Yes, sir.

Meghan Rowlands. 21. American, post-grad.

Also the morning tour guide. Really?

Yeah. Then where's her group?

Presumably she had a group. Where are they?

Did they just leave without their tour guide?

Oh, oh, Chief...I actually think that is exactly what they did.

They run two walking tours a day.

A full circle of Cambridge, always starting in the square

and ending here.

This is basically the last stop.

They're given some spiel about the history of the place,

then basically left to wander and leave of their own accord.

Well, then she must have had to come back for some reason,

forgotten something - her bag maybe?

She had it on her when she died.

Look, I mean, it obviously didn't happen whilst they were still here,

otherwise someone would have seen.

Perhaps.

Perhaps not.

Sir?

Well, whatever they witnessed, they were the last people to see

her alive and we have no idea who they are or how to find them.

Oh, actually, Chief, they had to fill in their email addresses

when they bought the tickets, so...

Ha-ha! God bless mail list marketing.

All I'm saying maybe we should, you know, keep an open mind here.

What's happening now?

You fill him in. I'll... I'll go do some more digging.

Fill me in on what?

I thought it would be a good idea to employ a member of Gen Z

to do a deep dive on this Roger Sinclair chap.

And now I rather wish that I hadn't.

Sinclair was a conspiracy theorist - and a pretty batty one at that.

Course, you can imagine how Henry's taken this.

He's now got his father single-handedly

fighting the Illuminati.

I highly doubt he believes that.

Really? It makes his father the hero.

Isn't that what every boy wants?

How was your day?

Someone murdered a tour guide in a church.

Yes, no, sorry. I meant,

"How was your day in terms of our investigation?"

Right, yes, sorry.

Well, I've actually been looking over the original crime scene report

again, and everything about it seems...

No, John, you've read that over and over again.

What you were supposed to be do today is get closer to DI Carter.

I really wish you'd stop phrasing it like that.

It sounds like I'm supposed to go camping with him or something.

Look, I... I tried, OK?

I did exactly what you said.

I found my moment and attempted some...

..non-work related casual conversation with him.

No phone.

Given her age and occupation, that's a bit...

That's a bit strange. Holly, do you think you could get a...?

Already found her. She's got an active phone contract.

Ooh, we should grab food whilst we can.

Oh. Yes, together.

Good idea. Let's do that. Let's...grab food.

Do you follow...football at all?

And apparently he does.

Liverpool FC.

He's a season ticket holder.

What?

John, this Russell character magically appeared at the exact

same time as James vanished.

He's taking personal calls from Chief Constable Ziegler,

the one person that we do know is involved in all this,

then he lies to you about it,

and despite all that we know nothing about him.

I'm sorry, but supporting Liverpool does not quite cut it.

You'll be asking him what his favourite colour is next.

It's probably red. No, John, it doesn't matter.

It doesn't help us.

Look, what we need is personal information - who he is,

where did he come from? What's his connection to Ziegler?

I mean, you spend eight hours a day with him.

You need to tease out some kind of backstory.

I mean, you're the one that's supposed to be a genius round here.

Two points above actually,

but I find that never helps

when it comes to...chatting.

Couldn't you do a high dive on him?

Oh, I tried that. It turns out he's got an even less of

an online presence than...

..well, you.

I have been looking into their supposed burglar,

this guy they arrested, Rhys Bowen.

He lives with his mother up on Heywood Rise.

Actually she's started a crowd-funder for his appeal.

See?

£10?

That's not going to be anywhere near enough.

Now, ah, listen - and don't say, "No," OK?

I'm not committing to that. I don't know what you're going to say.

Well, does it matter? I've told you not to, so you can't now.

I really don't think that's legally enforceable.

I'm going to go and visit her tomorrow.

It's fine, it's fine.

I've planned it all. I'm going to say that I am a local journalist

covering her story, and she might arrange for me to meet her son.

What? In prison?!

Well, no. I thought they might let him out on a day release

and I could see him in a local Costa.

Yes, in prison.

It's no more dangerous than what you're doing.

Yes, but it doesn't matter what happens to me.

Of course it does.

Not as much.

That's very sweet, John. Thank you.

I'm still going, though.

What if I said more reasons why you shouldn't go?

I'd probably tell you that I'm not discussing it any further.

That does sound like something you'd say.

Pity, because I had some really good ones.

Guv.

Ah. Thanks.

Oh, there's sugar in it!

Ah... Yeah, there is.

Which, as you know, is exactly how I like it.

Cheers!

Good news, Guv.

Every single one of the tour group replied overnight.

We have names, addresses, everything.

Oh, I was hoping one of them wouldn't,

cos that would've meant that they were probably the killer.

Right, well, in that case, bad news, Guv.

We've identified all the suspects.

Mr and Mrs Tate live locally.

The tour was an anniversary surprise, apparently.

And they say romance is dead.

Ah, Myles North and Yuna Chen, they're roommates and students.

They live near the college.

And these three ladies here are actually mother, daughter

and grand-daughter. They're over from France.

Erm, sir?

Morning. I'm going to be quick.

We're cribbing officers from every department.

I need three from you, the best you've got -

we're putting together an emergency taskforce.

For what, ma'am?

To find the missing son of a millionaire.

Oh, a kidnapping?

I wouldn't have thought so, Sergeant Finch.

The individual in question is Jordan Halshaw.

Oh...

Sorry to disappoint!

Oh. No, no, no, I wasn't...

I'd never... I wouldn't...

Oh, she's just always wanted to do a kidnapping.

Investigate one, I mean.

Ah, sorry, who exactly is Jordan Halshaw?

DCI Taylor, would you like to fill in our new DI

on the Halshaws of Cambridge?

Oh, of course, yes. Well, erm... They're, ah...

Well, erm... Perhaps Constable Evans would like the honour?

Oh, sure. Thanks.

Well, he's Cameron Halshaw's son.

Cameron Halshaw Developments? You've probably seen the signs everywhere.

Bit of a... Halshaw junior is a walking liability.
