The Knife was gulping. It slurped like a toothless man inhaling a bowl of wet noodles.

Sephrimel made a low choked sound. "Inhana," he whispered, black blood dripping down and dewing my left cheek. He was close as a lover, and the weight of his body against mine was enough to touch off panic in the darkest corners of my head. "A'tai, hetairae A'nankimel'iin. Diriin."

My back, against cold hard stone, ran with prickles. It was a phrase Japhrimel had spoken to me, one I recognized even though I couldn't translate it. Something about a hedaira and an A'nankhimel.

But in return you will perform me a service, and if you do not I will strike you down to revenge myself on your lover.

He hadn't wanted to kill me. I realized it only now, too late to pull back. He'd attacked me so I would kill him. Tit for tat. Japhrimel had killed his hedaira, and here I was, finishing up the job.

Ohgods I've killed him. Oh gods.

Sephrimel's eyelids fell. His gaunt, starving face relaxed. I heard a sobbing noise, realized it was mine, repeating the only prayer I had left.

"Japh… Japhrimel ohgods help… "

The gulping sound ceased. Ash trickled through veins of darkness running through the demon's golden flesh. Like porcelain, his skin cracked and broke, larger shards crumbling into fine cinnamon-scented dust. The veins of dryness even spread to his hair, threading through the clotted white.

The Fallen demon exploded into ash that ground itself finer and finer as a heavy silken tide of pleasure slammed through me. My heart drummed against my rib cage like a hummingbird's wings, the space where something had been ripped from my belly throbbing in response. My hips jerked up as I tasted the remainder of ash, vanishing until no trace of spice or musk remained on the air.

I gasped, got another mouthful of salt water, and scrambled to my feet. I wasn't losing my balance, the dome trembled. A chunk of stone fell from the vault, landing with an ominous splash. Ohgods. Oh, dear gods.

My knees almost gave out on me. I backed away from the spreading fine film of ash on the water's chopped surface. Is the whole place shaking, or just here? Great. I'm underground and I just killed my only guide. Just wonderful, Danny. I backed up, hardly caring where I stepped at this point, and my shoulders hit the wall with a thump. I stared up, only dimly aware of pleading. "Please don't fall, don't fall, don't fall-"

The dome shuddered once. Water trembled. Two things became apparent to me at once. The first was that something else was causing it to shake, some event communicating itself through stone like the squeal of overstressed hover dynos cuts through concrete like jelly.

The second thing was that the water was rising, lapping at my knees instead of my shins.

Move, Danny. Move now.

I bolted for the door as another huge chunk of stone tore free of the dome, falling with a whistle and sending up a sheet of foaming, ash-laced seawater. My fingers clamped around the Knife's satin-smooth, warm wooden hilt, and even in my adrenaline-laced terror I didn't want to drop the goddamn thing. If it could kill Lucifer — or even wound him — the last place I wanted it to end up was buried under tons of rubble.

Though it just might end up there anyway. Run, Danny. Run.

I ran.

Chapter 10

Mysense of direction underground isn't the greatest. Fortunately, my Magi-trained memory had been busy taking in the mosaics, and Inhana's sad, lovely face pointed me the right way.

I hoped like hell that Sephrimel hadn't repeated the patterns over and over again down every passage. That's a thought you don't need, sunshine. Just keep moving.

I did, because the air was moving with me, a cold exhalation of salt brushing my hair as I pounded down stone worn concave by a demon's dragging, grieving feet. I hit the door to the room I'd awakened in at full tilt, smashing it back against the wall, and shoved it shut with hysterical speed. Then I halted, my ribs flaring and flickering as I gasped, looking around for some clue of how to get out of here. The bookshelves looked too flimsy for anything, and the scrolls stacked on them were no help either, their smell a blind weight in my nostrils.

Up. Got to get up. When my breathing evened out, the low groaning coming through the stone became audible again. I turned in a full circle, searching for another door, and realized my folly almost immediately. Just because I'd woken up here didn't mean this room had an escape hatch.

Think, Danny. Quit fucking around and think!

I cast around again, trying desperately to force my brain to gear up and get me out of this one. Then the thing I was afraid of most happened.

Water trickled under the door, a few innocent little streamlets sending thin questing fingers over the dry stone.

"Shit," I hissed between my teeth.Trust you to end up like this. Going to drown like a rat in a sewer if you don't-"Shut up. Shut up. Think, damn you! Think!"

I would never have seen it if I hadn't hunched down, clapping my hands to either side of my head and thwacking myself a good one with the Knife's hilt against my temple. I'd almost forgotten I was carrying the damn thing.

When my eyes cleared, smarting and stinging furiously, my attention snagged on the wall directly over the chunk of stone Sephrimel had laid me out on. The mosaic there was blues and greens, and it stretched up in a passable imitation of a door, a round wheel of yellow right where the knob should be.

The edges of the pattern shimmered, just like a psion's glamour once you've slowed down to take a really good look at it. Illusion rippled, and my heart leapt up into my throat, pounding there like it intended to tear free of my ribs and dance.

I didn't stop to think. I scrambled across the room, wet feet skidding in the rivulet of water coming under the door, leapt up -

— and smashed into the wall full-tilt, knocking myself half-senseless back down onto the rectangle of stone.

I shook the stunning impact out of my head. Dante, you idiot. And with the utter lunacy of the desperate, shell-shocked, and insane, I reached up, my claw-tips scraping against polished bits of stone, and touched the yellow circle.

It felt round, firm, and real, under the screen of demon illusion. I used it to pull myself to my knees, hearing the soft insidious lap of water against the base of the stone chunk. It was rising fast.

I twisted my wrist. The shell of illusion on the door — a perfect piece of demon magick, either a cruel mockery or an aesthetic utterly divorced from practicality — folded aside as the door swung open, the golden orb at the apex of the dome beginning to dim as its light spilled through…

And touched stairs. Going up.

I let out a relieved sob and began to scramble on hands and knees, the worn edges of the risers biting into my flesh. The Knife made a little clicking sound against each step until I managed to get my legs under me. I ran, heart exploding with pain inside my ribs and the fear of the caverns behind me, filling with cold stone water mixed with Sephrimel's ashes, in my mouth like bitter wine.

The stairs were narrow and dark, golden light from below fading as water mouthed and lapped behind me. If I could have stopped, I probably would have lain down despite the hard stone edges and tried to at least catch my breath. As it was, I had a hard enough time trying to keep myself upright, slipping on slick stone.

I ran, my fingers cramping around the Knife's warm pulsing hilt. Sick fever-warmth spilled up my arm with each pulse. Whatever it had taken from Sephrimel it was feeding into me, in controlled bursts like an immuno-hypo's time-release function. I'd been hurt bad enough, once or twice as a human bounty hunter, to slam painkiller cocktails from a first-aid kit. This was the same feeling — knowing the pain was there, that I was functioning on borrowed time, that soon I was going to push my body past its limits, muscles tearing free of their moorings and my brainpan filling with blood from burst vessels. Danny, you're running blind. Slow down.
