I knew then, instinctively, what had taken control of Anton's body. A demon, a high-ranking one, the kind that should never-and usually could never-be summoned.

I dropped my gaze. The demon loosened his grip on my chin and stroked my cheek with his forefinger.

"Smart witch," he murmured. "Don't worry. It was a mistake."

Behind us, Sandford's lips moved in an incantation. Though no sound reached my ears, the demon swung around, letting me go and turning on Sandford.

"What are you doing?" the demon said.

Sandford's lips kept moving, but he shrunk back as the demon bore down on him.

"What do you think I am?" the demon thundered, bringing his face to Sandford's. "You dare try to send me back? With a spell to dispel some mewling spirit?"

Sandford's voice rose, words spilling from his mouth.

"Show some respect, sorcerer!"

The demon grabbed Sandford by the shoulders. Sandford squeezed his eyes tight and kept casting.

"Fool! Disrespectful fool!"

With a roar, the demon pulled back his hand and slammed it into Sandford's chest. Slammed it into his chest, fingers disappearing inside Sandford's torso. The muscles on the demon's arm tightened, as if squeezing. Sandford's mouth opened in a silent scream. The demon withdrew his hand, bloodless, and let Sandford's body fall to the floor. Then he turned to me.

A protective spell flew to my lips, but I swallowed it back and forced myself to stand up straight, meeting his gaze, firm but not defiant.

He strode back to me and his hand cupped my chin again, lifting my face to his. His eyes searched mine. I fought the urge to look away. For a long minute, he just stared at me… into me. Then his lips curved in a smile and he released my chin.

He stood there, watching me for a moment, then turned and headed down the hall. After a few steps, he lifted his hands and Anton's body dropped to the floor. A sharp wind, as hot as a furnace blast, encircled me, then was gone.

I wrapped my arms around me, shaking despite the heat. Looking down at Sandford, I saw his shirt was neither torn nor bloodied, as if I'd only imagined what I'd seen. Shivering, I stepped over his lifeless body.

Anton's corpse lay several feet away, also blocking the hall. He was on his stomach, face turned toward the wall, eyes closed. As I lifted my foot to step over him, his body convulsed. I jerked back, stumbling into Sandford. Anton's body shook and twisted, bucking off the floor. Then it went still.

I fought to control my racing heart, then lifted my foot slowly. Dime-store magic, I told myself. Yet that mantra no longer worked, no longer held true. There were things here that could hurt me, things my brain could barely fathom.

As my foot passed over Anton's head, his eyes opened and I fell back with a shriek. Anton's head rose and jerked from side to side. Thenit turned nearly full around, bones snapping. His eyes met mine. The bright green irises were gone, replaced by dull yellowish disks with huge pupils. Those reptilian eyes fixed on mine, wide and unblinking. The mouth opened and a stream of high-pitched gibberish flew out. Then the thing that had been Anton rose up onto its fingertips and toes, lifting itself just inches from the floor and skittered into the next open room. From within the room came more gibbering, then the scratching of nails moving fast against the wooden floor.

I dove past the open door and ran for the front stairs, taking them two at a time. Halfway down, the step beneath me split in two. I stumbled and grabbed the railing. The next step cracked, then the next and the next, pieces dropping into the empty hole below. I raced back up the stairs, hearing the steps crackle and splinter in my wake.

I dashed for the back stairs, gaze trained on the doorway ahead. Something hissed in my path and I stopped short. Anton-or what had been Anton-was now back in the hall, crouched over Sandford's corpse. The creature hissed and snuffled at my approach, but kept its face against Sandford's torso, as if sniffing it.

I looked back at the front steps, now a twelve-foot sheer drop. Then I glanced at the creature. It still hadn't lifted its head, didn't even seem to know I was there. If I could just step over-oh, God, you must be kidding! I bit back my horror and steeled myself. A short run, a jump, and I'd be at the back stairs. I just couldn't think about what I was jumping over.

As I prepared to sprint, I changed my mind. I'd flunked track-and-field in elementary school, being unable to clear even the lowest hurdle. If I ran and jumped, I risked kicking the creature and pissing it off. Instead I tiptoed across the hall, then pressed myself against the wall and began slowly sidestepping toward Sandford's body. His arm was stretched over his head. Carefully I stepped over it, then continued inching sideways, past his head and along his upper chest. The creature was still crouched over Sandford's stomach, with its feet braced against the wall.

I lifted my foot to step over. Its head shot up and twisted full around, yellow eyes meeting mine. Strings of Sandford's flesh hung from its mouth and teeth. It hissed, spraying me with gore. I screamed then, screamed as loud as I could and wheeled, instinctively heading back to the front steps. I only got as far as Sandford's outstretched arm, tripped over it, and sailed to the floor. Something moved across my legs and I reared up, kicking and screaming. I couldn't stop screaming. Even knowing I was wasting energy-and possibly attracting more horrors-I couldn't stop.

The thing that had been Anton squirmed over me, pinning me to the floor. As hard as I punched, I couldn't even make it flinch. It moved up my chest until its face was over mine, dribbling bits of bloodied flesh onto my mouth and cheeks.
