No mailmen, but no librarians either. It’s all very Back Office, just as Angleton described it. I head for the nearest door, just as it opens in front of me.

“Hey-”

I blink. “Hello?” I ask.

“You’re not supposed to be here,” he says, annoyed if not outright cross. “Visitors are restricted to levels five and six only. You could do yourself a mischief, wandering around the subbasement!” In his shirt and tie and M &S suit he’s like an intrusion from another, more banal, universe. I could kiss him just for existing, but I’m not out of the woods yet.

“Sorry,” I say contritely. “I was sent to ask for a new document that’s supposed to have come in this morning…?”

“Well, you’d better come with me, then. Let me see your ID, please.”

I show him my warrant card and he nods. “All right. What is it you’re after?”

“A file.” I show him the slip of paper on which I’ve written down Mo’s document reference. “It’s new, it should have come in this morning.”

“Follow me.” He leads me through a door, to a lift, up four levels and along a corridor to a waiting room with a desk and half a dozen cheap powder-blue chairs: I vaguely recognize it from a previous visit. “Give me that and wait here.”

I sit down and wait. Ten minutes later he’s back, frowning. “Are you sure this is right?” he asks.

Annoyed, I think back. “Yes,” I say. I read the number back to Mo, didn’t I? “It’s a new file, deposited last night.”

“Well, it’s not here yet.” He shrugs. “It may still be waiting to be allocated a shelf, you know. That happens sometimes, if adding a new file triggers a shelf overflow.”

“Oh.” Mo won’t be happy, I guess, but it establishes my cover. “Well, can you flag it for me when it comes in?”

“Certainly. If you can show me your card again?” I do so, and he takes a note of my name and departmental assignment. “Okay, Mr. Howard, I’ll send you an email when the file comes into stock. Is that everything?”

“Yes, thanks, you’ve been very helpful.” I smile. He turns to go. “Er, can you remind me the way out…?”

He waves a hand at one of the doors. “Go down there, second door on the left, you can’t miss it.” Then he leaves.

THE SECOND DOOR ON THE LEFT OPENS ONTO A SMOOTH-FLOORED tunnel lined in white glazed tiles and illuminated by overhead fluorescent tubes of a kind that are sufficiently familiar that, when I reach the end of the tunnel and step through the gray metal door (which locks behind me with a muffled click) I am unsurprised to find myself in a passage between two tube platforms.

Half an hour and a change of line later, I swipe my Oyster card and surface, blinking at the afternoon sun. I pat the inside pocket where I secreted the sheaf of papers that Angleton gave me. And then I head back to my office in the New Annexe, where I very pointedly dial open my secure document safe and install those papers, then lock it and go home, secure in the knowledge of the first half of a job well done.

(Like I said: fatal accidents never happen because of just one mistake.)

11. CRIME SCENES

I DON’T FUNCTION WELL IN THE SMALL HOURS OF THE MORNING. I sleep like a log, and I have difficulty pulling my wits about me if something wakes me in the pre-dawn dark.

So it takes me a few seconds to sit up and grab the bedside phone when it begins to snarl for attention. I fumble the handset close to my face: “Whuuu-” I manage to drone, thinking, If this is a telesales call, I’ll plead justifiable homicide, as Mo spasms violently in a twist of the duvet and rolls over, pulling the bedding off me.

“Bob.” I know that voice. It’s-“Jo here. Code Blue. How soon can you be ready for a pickup?”

I am abruptly awake in an icy-cold drench of sweat. “Five minutes,” I croak. “What’s up?”

“I want you in here stat, and I’m sending a car. Be ready in five minutes.” She sounds uncertain… afraid? “This line isn’t secure, so save your questions.”

“Okay.” The phrase this had better be good doesn’t even reach my larynx: declaring Code Blue is the sort of thing that attracts the Auditors’ attention. “Bye.” I put the phone down.

“What was that?” says Mo.

“That was a Code Blue.” I swing my feet over the edge of the bed and fish for yesterday’s discarded socks. “There’s a car calling for me in five minutes.”

“Shit…” Mo rolls over the other way and buries her face in a pillow. “Am I wanted?” Her voice, muffled, trails away.

“Just me.” I paw through an open drawer for pants. “It’s Jo Sullivan. At four in the morning.”

“She’s with Oscar-Oscar, isn’t she?”

“Yup.” Pants: on. Tee shirt: on. Trousers: next in queue.

“You’d better go.” She sounds serious. “Phone me the instant you hear something.”

I glance at the alarm. “It’s twenty to five.”

“I don’t mind.” She pulls the bedding into shape. “Take care.”

“And you,” I say, as I head downstairs, carrying my holstered pistol.

I’m standing in the front hall when blue and red strobes light up the window glass above the door. I open it in the face of a cop. “Mr. Howard?” she asks.

“That’s me.” I hold up my warrant card and her eyes age a little.

“Come with me, please,” she says, and opens the rear door for me. I strap myself in and we’re off for another strobe-lit taxi ride through the wilds of South London, speeding alarmingly down narrow shuttered streets and careening around roundabouts in the gray pre-dawn light until, after a surprisingly short time, we pull up outside the staff entrance to a certain store.

The door is open. Jo is waiting for me. One look at her face tells me it’s bad. Angleton warned me: This is where it starts. I tense. “What’s happened?” I ask.

“Come this way.” Jo leads me up the stairwell. The lights are on, which is abnormal, and I hear footsteps-not the steady shuffle of the night staff, but boots and raised voices. Something in the air makes me think of a kicked anthill.

We head past reception where a couple of blue-suited security men are standing guard over a stapler and six paper clips, then back along the corridor past Iris’s corner office, then round the bend to-

“Fuck,” I say, unable to contain myself. My office door is closed. But I can see the interior, because there’s a gigantic hole in the door, as if someone hit it with a wrecking ball. (Except a wrecking ball would leave rough jagged edges of splintered wood, while the rim of this particular hole looks oddly melted.) The interior isn’t much better; an avalanche of paper and scraps of broken metal are strewn across half an overturned desk. A thin blue glow clings patchily to some of the wreckage, fading slowly even as I watch. “What happened?”

“Am hoping you tell us.” It’s Boris, bags under his eyes and an expression as dark as midnight on the winter solstice. When did he get back? Wasn’t he doing something overseas connected with BLOODY BARON…?

“What have you done, Bob?” Jo grabs my left elbow. “First a civilian FATACC, now this. What are you into?”

I blink stupidly at the destruction. “My secure document safe, is it…?”

She shakes her head. “We won’t know until we go inside. It’s still active.” I feel a thin prickling on the back of my neck. Demonic intruders have been at work, summoned to retrieve something. Angleton was right, I realize.

“What did you have in your safe?”

“I’m not sure you’re cleared-”

Boris clears his throat. “Is cleared, Bob. I will clear her. What was in safe? What attracted attention of burglars in night?”

I squint through the hole in the door. “I had documents relating to several codeword projects in there,” I say. “The stacks can probably reconstruct my withdrawal record, and once it’s safe to go in there we can work out what is missing.”
