She opens the site and scrolls a full page of posts. Several pages have accumulated in the course of the day, in the wake of the surfacing of #135, but she has no appetite for them now.

It seems beside the point.

A wave comes crashing, sheer exhaustion, against which the Colombian is no defense.

She takes off her clothes, brushes her teeth, limbs wooden with exhaustion and vibrating with caffeine, turns off the lights, and crawls, literally, beneath the stiff silver spread on Damien's bed.

To curl fetal there, and briefly marvel, as a final wave crashes over her, at the perfect and now perfectly revealed extent of her present loneliness.

Somehow she sleeps, or approximates it, through the famously bad hour and into another mirror-world morning.

Waking to an inner flash of metallic migraine light, as if reflected off wings of receding dream.

Extrudes her head turtle-wise from beneath the giant pot-holder and squints at the windows. Daylight. More of her soul has been reeled in, it seems, in the meantime. Apprehending self and mirror-world now in a different modality, accompanied by an unexpected surge of energy that has her out of bed, into the shower, and levering the Italian chromed head to stinging new foci of needle jets. Damien's reno has involved hot water, lots of it, and for that she is grateful.

It is as though she is inhabited now by something single-minded, purposeful, yet has no idea what it plans, or wants. But she is content, for the moment, to go along for the ride.

Blow-dry. CPUs include the black jeans.

Mirror-world milk (which is different, though she couldn't say how) on the Weetabix, with a sliced banana. That other part of her, that other self, moving right along.

Watching as that part seals over the cigarette burn with black gaffer's tape, the ends tooth-torn, a sort of archaic punk flourish. Pulls on the Rickson's, checks for keys and money, and descends Damien's still-unrenovated stairwell, past a tenant's mountain bike and hip-high bundles of last year's magazines.

In the sunlit street, all is still; nothing moves save the cinnamon blur of a cat, just there, and gone. She listens. The hum of London, building somewhere.

Feeling inexplicably happy, she sets off down Parkway toward Cam-den High Street, and finds a Russian in a mini-cab. Not a cab at all, really, just a dusty blue mirror-world Jetta, but he will drive her to Netting Hill, and he looks too old, too scholarly, too disgusted by the very sight of her, to be much trouble.

Once they are out of Camden Town she has little idea of where they are. She has no internalized surface map of this city, only of the underground and of assorted personal footpaths spreading out from its stations.

The stomach-clenching roundabouts are pivots in a maze to be negotiated only by locals and cabdrivers. Restaurants and antique shops rotate past, punctuated regularly by pubs.

Marveling at the luminous shanks of a black-haired man in a very expensive-looking dressing gown, bending toward the morning's milk and paper in his doorway.

A military vehicle, its silhouette unfamiliar, bulk-browed, tautly laced beneath its tarpaulin. The driver's beret.

Mirror-world street furniture: bits of urban infrastructure she can't identify by function. Local equivalents of the mysterious Water Testing Station on her block uptown, which a friend had claimed to contain nothing more than a tap and a cup, for the judging of potability—this having been for Cayce a favorite fantasy of alternative employment, to stroll Manhattan like an itinerant sommelier, addressing one's palate with the various tap waters of the city. Not that she would have wanted to, particularly, but simply to believe that someone could do this for a living had been somehow comforting.

By the time they arrive at Netting Hill, whatever rogue aspect of personality has been driving this morning's expedition seems to have de-camped, leaving her feeling purposeless and confused. She pays the Russian, gets out on the side opposite Portobello, and descends the stairs to a pedestrian tunnel that smells of Friday-night urine. Overly tall mirror-world lager cans are crushed there like roaches.

Corridor metaphysics. She wants coffee.

But the Starbucks on the other side, up the stairs and around a corner, is not yet open. A boy, inside, wrestles huge plastic trays of cello-phaned pastries.

Uncertain what she should do next, she walks on, in the direction of the Saturday market. Seven-thirty, now. She can't remember when the antiques arcades open, but she knows the road will be jammed by nine. Why has she come here? She never buys antiques.

She's in a street of what she thinks are called mews houses, little places, scarily cute, still headed toward Portobello and the market, when she sees them: three men, variously jacketed, their collars up, staring gravely into the open trunk of a small and uncharacteristically old mirror-world car. Not so much a mirror-world car as an English car, as no equivalent exists, on Cayce's side of the Atlantic, to mirror. Vauxhall Wyvern, she thinks, with her compulsive memory for brand names, though she doubts that this is one of those, whatever those might have been. As to why she notices them now, these three, she later will be unable to say.

No one else in the street, and there is something in the gravity they bring to their study of whatever it is they are looking down at. Careful poker masks. The largest, though not the tallest, a black man with a shaven head, is zipped like a sausage into something shiny, black, and only approximately leatherlike. Beside him is a taller, gray-faced man, hunched within the greasy folds of an ancient Barbour waterproof, its waxed cotton gone the sheen and shade of day-old horse dung. The third, younger, is close-cropped and blond, in baggy black skater shorts and a frayed jean jacket. He wears something like a mailman's pouch, slung across his chest. Shorts, she thinks, drawing abreast of this trio, are somehow always wrong in London.

She can't resist glancing into the trunk.

Grenades.

Black, compact, cylindrical. Six of them, laid out on an old gray sweater amid a jumble of brown cardboard cartons.

"Miss?" The one in shorts…• _

"Hello?" The gray-faced man, sharply, impatient.

She tells herself to run, but can't.

"Yes?"

"The Curtas." The blond one, stepping closer.

"It isn't her, you idiot. She's not bloody coming." The gray one again, with mounting irritation.

The blond one blinks. "You haven't come about the Curtas?"

"The what?"

"The calculators."

She can't resist, then, and steps closer to the car, to see. "What are they?"

"Calculators." The tight plastic of the black man's jacket creaking as he bends to pick up one of the grenades. Turning to hand it to her. And then she is holding it: heavy, dense, knurled for gripping. Tabs or flanges that look as though meant to move in these slots. Small round windows showing white numbers. At the top something that looks like the crank on a pepper mill, as executed by a small-arms manufacturer.

"I don't understand," she says, and imagines she'll wake, just then, in Damien's bed, because it's all gone that dreamlike now. Automatically seeking a trademark, she turns the thing over. And sees that it is made in Liechtenstein.

Liechtenstein?

"What is it?"

"It is a precision instrument," the black man says, "performing calculations mechanically, employing neither electricity nor electronic components. The sensation of its operation is best likened to that of winding a fine thirty-five-millimeter camera. It is the smallest mechanical calculating machine ever constructed." Voice deep and mellifluous. "It is the invention of Curt Herzstark, an Austrian, who developed it while a prisoner in Buchenwald. The camp authorities actually encouraged his work, you see. 'Intelligence slave,' his title there. They wished his calculator to be given to the Fuhrer, at the end of the war. But Buchenwald was liberated in 1945 by the Americans. Herzstark had survived." He gently takes the thing from her. Enormous hands. "He had his drawings." Large fingers moving surely, gently, clicking the black tabs into a different configuration. He grasps the knurled cylinder in his left, gives the handle at the top a twirl. Smoothly ratcheting a sum from its interior. He raises it to see the resulting figure in a tiny window. "Eight hundred pounds. Excellent condition." Dropping an eyelid partially, to wait for her response.
