Five minutes later, another windowless office with overflowing bookshelves and too many filing cabinets. "What have you got for me?" he asks. Balding, in his late forties, Nick is the research lead in this particular lab.

"A special job." Mo pauses. "Sub rosa."

"Sub—Oh shit. Tell me it isn't so."

She shakes her head. "I think it's probably a leak rather than an inside job, but even so, this is for you, not the office junior. Eyes only." She pulls out the tub of paper clips from Mr. Dower's workroom, and the small stapler from beside his cash register, and places them on the worktable opposite Dr. Williams's desk. "The owner of these items was murdered about forty-eight hours ago. He'd just prepared a special report for me. I'm pretty certain the killer took the report, and knowing George—the victim—he would have paper-clipped or stapled it. So I want a full read on the top copy—and a locator."

Dr. Williams whistles between his front teeth. "You don't want much, do you?" He pauses. "When do you need it by?"

"Right now." Mo positions her violin case on the visitor's chair, then lets go of it. "It's very urgent."

"Oh. I can have it with you by eight tonight, if I—"

"No." She smiles, letting him see her teeth. "When I said now, I meant right now."

"What's so urgent?" Williams, unwilling to be rushed, crosses his arms and stares at her.

"Are you on the distribution for CLUB ZERO?"

Williams's face turns ashen. "That was the business in Amsterdam, wasn't it?"

"They're over here, too. The document in question is a detailed report on that." She points at the violin case. "Whoever has got the report is almost certainly a live hostile, and may I remind you that the item they're after is in your office?" Her smile evaporates. "You really want to get me out of here . . ."

THERE IS A PHILOSOPHY BY WHICH MANY PEOPLE LIVE THEIR lives, and it is this: life is a shit sandwich, but the more bread you've got, the less shit you have to eat.

These people are often selfish brats as kids, and they don't get better with age: think of the shifty-eyed smarmy asshole from the sixth form who grew up to be a merchant banker, or an estate agent, or one of the Conservative Party funny-handshake mine's-a-Rolex brigade.

(This isn't to say that all estate agents, or merchant bankers, or conservatives, are selfish, but that these are ways of life that provide opportunities for people of a certain disposition to enrich themselves at the expense of others. Bear with me.)

There is another philosophy by which people live their lives, and it goes thus: you will do as I say or I will hurt you.
