Inserted into the keyhole, the first key opened the trap door with a low, hard snap, and together the boy and Gideon threw it open. It revealed a ladder of metal staples down a long, unbelievably dark hole: light shaded in at the bottom, throwing into relief the fact that one slip meant a broken neck along with your broken ass-bones.
A pointing finger appeared in front of her like a spear tip: Camilla’s. The Sixth cavalier had reclaimed the flashlight, and by its glow she could see that Camilla’s eyes were much darker than her necromancer’s: his were like clear stone or water, and hers were the unreflective, fathomless colour of overturned Ninth House sod, neither grey nor brown. “You go first, Ninth,” she said. “Palamedes follows. I bring up the rear.”
It took a full minute to descend that long, claustrophobic tube, staring at the rungs of the ladder with her robes tucked between her knees, sword clanking on metal all the way down—and at the bottom, Gideon was utterly nonplussed.
What lay beneath the trapdoor was a retro installation. A six-sided tunnel lined with dusty, perforated panels stretched out before them. The ceiling was merely a grille that air coolers pumped through and the floor a grille with visible pressure pumps beneath, and the lights were electric bulbs beneath luminous white plastic. There were exposed pipes. The supporting archways contained bulky, square autodoor sidings. This rhapsody of greys and sterile blacks was interrupted over the nearest arch, where, twisting in the dry breeze of the climate cooler, hung a bundle of old bones. Ancient prayer wrappers were ringed around it, and it was the only human, normal touch.
“Follow me,” said the young man called Palamedes.
He strode forward, filthy hem whispering on the dusty-ass tiles. This place ate sound. There were no echoes: they were squashed and absorbed into the panelling. The three of them clanked unmusically down the tunnel until it opened into a big nonagonal room, with passageways radiating out like bronchiae. Letters of brushed steel were set beside each passage:
LABORATORY ONE–THREE
LABORATORY FOUR–SIX
LABORATORY SEVEN–TEN
PRESSURE ROOM
PRESERVATION
MORTUARY
WORK ROOMS
SANITISER
Light wells above made the panelling white; lights from below—little blinking lights attached to huge machines that went down metres beneath the grille, a huge deep way beneath their feet—made the floors softly green. The walls were unadorned, except for an enormous old whiteboard rimmed in metal, printed with lines for a timetable that had not been used in a very, very, very long time. The lines had blurred; the board was stained. Here and there meaningless bits of letters survived: the loop of what might be O or C; the arch of an M; a line-suffixed curve that could be G or Q. But in one bottom corner lingered the ghost of a message, drawn thickly in black ink once, now faded but still quite clear:
It is finished!
The atmosphere down here was oppressive. The air was so dry it made her eyes and mouth prickle. Camilla had one hand on her sword, and Palamedes kept wringing his together, rocking from foot to foot as he moved in a long, slow, 360-degree sweep of the room. At some stimulus, or lack of stimulus, he took a sharp turn toward Sanitiser. Gideon followed.
The short hallway to Sanitiser was floored with panels rather than grille, covered in a powdery build-up like salt, scuffed underfoot and heaped in little drifts. These dunes dissolved like an exhaled breath if kicked.
Quite abruptly there was blood. Palamedes thumbed his tiny flashlight out of his pocket and the liquid gleamed redly beneath the beam. Blood had been spilt, in some quantity, and then smeared heavily away down the hall, leaving a long dark scrape of drying gore. Smaller splatters had dried on the surrounding walls.
The door at the end of the hallway—a huge blast door, metal, with a glass panel set in its centre that was so grimy you could no longer see through it—opened with a touchpad that was also smudged with curls of dried blood. Dried, and drying. Gideon pressed it so hard that the doors twanged open like they were startled.
The first room of Sanitiser stretched before them as a huge, low-ceilinged, white-panelled maze of cubicles: long steel tables beneath the upside-down metal mushrooms of spray heads, and narrow boxes a human could stand upright in. It was fully as big as the grand, destroyed hall of Canaan House. The lights whirred overhead. A panel on the wall blinked furiously as some mechanism in it tried to wake up—it looked like a screen—but eventually it decided better, went blank, and the room was resubmerged in shadow. Gideon was hunting with a dog’s mindless, preternatural panic for a scent, trying to find—
