Camera moves to Mitchell. He’s in his forties, with a shaven head, glasses and a short beard which is going grey. He’s in a denim shirt with a patterned silk scarf.

MITCHELL CLARKE

My name is Mitch Clarke and I’m a journalist. I’ve contributed articles to the national and London press for nearly twenty years.

Though that’s not quite the whole story, is it?

MITCHELL CLARKE

(picks up a pen and starts playing with it)

No. I was also the first reporter on the scene on the night of the Ryder murder. In fact, I was there even before the police.

GUY HOWARD

And how that came to be the case is something we’re going to look into in a lot more detail as we get into the investigation.

Laila?

Camera moves to Laila. She’s in her late forties with olive skin, impeccable but understated make-up, and short grey hair; she’s wearing a green satin blouse, a silk scarf and a clutch of gold bracelets. She clearly takes a lot of care over her appearance.

LAILA FURNESS

I’m Laila Furness and I’m a forensic psychologist. I’ve worked alongside the Met, and at various UK prisons including Broadmoor. My speciality is serial killers.

GUY HOWARD

To be clear, there’s never been any suggestion that Luke was the victim of a serial killer.

LAILA FURNESS

(nods)

You’re right, there hasn’t. But as the police officers among us will know, you have to assessallpotential theories of a crime before you focus on one single line of enquiry.

BILL SERAFINI

I’d agree with that.

CAMERA MOVES to Bill. He’s a big man, in every respect. Imposing physically, and with considerable presence. He has a genial demeanour but he’s clearly not someone you’d want to cross. His suit is a little too small for him. He has a stars-and-stripes pin in his lapel.

BILL SERAFINI

My name is Bill Serafini, and I’m a retired NYPD detective.

MONTAGE of old photos of Bill. In uniform, receiving a medal, in plain clothes with a badge.

Murder, rape, arson, child abduction, gang crime, you name it, I’ve investigated it.

(smiles)

Not personally of course. I had thirty-plus years on the force and now I work as a private eye. Private investigator, as you British folks would say. Anything else you want to know, feel free to ask.

NICK VINCENT (Producer)

Thank you, Bill. And finally, JJ.
