The creature stumbled back, dropping me to the ground. Its eyes were wide and uncomprehending. I thought I saw a flicker of fear before it launched itself at me again. I leaped toward it, inside its swing, and brought my fist up into the soft place under its jaw. The bag of ashes and salt burst like a water balloon. The thing choked and stumbled back. Aubrey appeared from nowhere swinging a fire poker like it was a machete. The beast raised its arms to protect its head against the assault, and for five or six seconds I thought we stood a chance.

“Jayné! Stay back!” Aubrey shouted, but I was already in motion. It caught my leg as I tried to kick it, lifting me up like a twig. My knee shifted, and I shrieked with pain. I caught a glimpse of Aubrey—red-faced, his teeth bared in rage—flailing at the thing’s back with the poker. I was airborne. The plaster and lath wall gave when I hit it, but the sound of the fight was muffled now. Aubrey’s yelling was distant and soft, the beast’s answering howl no more than unpleasant. I tried to rise to my knees, but it didn’t go as well as I’d hoped.

I opted for sitting, and when I looked up, the thing was squatting before me. It didn’t look even vaguely human now. Its clothes were in ribbons, and the small glimmering badge that hung from one strip of shattered cloth seemed like an insult. The boots were strips of leather clinging to wide hooves. His belt…

I blinked, trying to gather myself. His belt was on the floor behind him. The gun was still in its holster.

“What are you?” it buzzed. I had the impression there was a light inside its mouth, like something was burning in there.

“My mother’s daughter,” I said blearily; I’d meant Eric when I said it. My brain was clearly getting scrambled. I dropped to my belly and kicked off from the wall, scooping up the belt, drawing the gun, and twisting back to face the thing almost before it could react. Almost, but not quite. Its fist came down on the bridge of my nose and the world turned monochrome and quiet.

I almost didn’t see the dog attack.

I wavered there on the edge of consciousness, and when I came back, the beast was grabbing at the German shepherd, whose teeth were buried in its neck. I raised the gun, but Aubrey put his hand over mine, pushing the barrel away.

“Can’t kill the body,” he grunted. “Need the body. Aaron! Close your eyes.”

I couldn’t tell if the dog complied, but Aubrey staggered to his feet, a small black cylinder in his fist. There was a hissing sound, and the beast howled, scrabbling at its eyes with fingers that gouged great strips of flesh from its face. The dog leaped back, whining, and my own eyes started to water. Mace. I really didn’t think that was going to stop it. I raised the gun again, but Aubrey had his arms spread wide, like he was gathering in the air itself. I saw his ribs flex as he breathed in, and I realized his shirt had been ripped apart somewhere in the violence. When he shouted, it wasn’t a human sound. It rang like a bell, like there was music in it, like there was an angel speaking my name in a voice so low it deafened.

The beast twisted, shuddered, and sat. Its skin grew pale, its head thin, its face human. Aaron the fiancé lay on the splinters of a couch, his body slack. Aubrey staggered and fell to his knees.

I crawled over, putting my hand on Aubrey’s thigh. He was trembling.

“Is it dead?” I managed to croak.

“Bound,” he said. “Sleeping. Should be okay until Ex gets here.”

“Good trick.”

“Eric showed me.”

“Could have tried it a little earlier, though,” I said.

“Yeah, I was thinking that myself,” he said, then smiled. There was blood on his teeth. I smiled back, and the dog came to us, licking Aubrey’s face nervously. I wanted to sleep, but instead I staggered to my feet and closed the blinds and the front door. The place was a ruin. Couch, coffee table, overstuffed chairs—all of them were broken. The walls were shattered in three places, and the glass shutters guarding the fireplace were shards clinging to strips of warped copper. I walked back to the kitchen, almost surprised to see it intact. I washed my hands until the shaking got too bad, and then I just stood there, leaning against the counter.

“You’re hurt,” Aubrey said from the doorway.

“No. I’m…” I looked down at my blood-soaked side. “Oh. Hey, yeah. I’m hurt.”

I laughed, and the pain shot out from my side to the base of my skull. Somehow that seemed hilarious, and I sank to the floor in a feedback loop of laughter and pain. I watched Aubrey’s feet come across the tile floor, felt his hands lift me up to sitting. When he pulled off my shirt, I didn’t stop him. I felt wrung out and quiet now. Through the door to the ruined front room, I saw the dog sitting, its eyes fixed, I assumed, on the newly human body resting in the wreckage. Aubrey’s left eye was swelling shut, and I could see a bruise darkening at his collarbone. His hands shook. He touched a warm cloth to my side and I winced.

“I’m sorry,” he said.

“It’s okay,” I said.

“No, I mean I’m sorry I brought you here. This was way more than I expected. It was stupid of me.”

“It’s okay,” I repeated.

“You could have been killed.” I was a little surprised by the distress in his voice. Maybe I shouldn’t have been. I took his hand in mine and drew his eyes up to meet my own.

“What would have happened to her if we hadn’t come?” I asked. Aubrey nodded as if accepting my point, but when he tried to look away, I squeezed his hand. “Really. What?”

“I don’t know,” he said. “In the short term, I don’t know. It would have tried to protect itself while it grew to maturity. Then probably it would have taken her over too.”

“The rider,” I said.

“Or its daughter organism, yeah,” Aubrey said. “This is how they breed. Or…well. I think it is. This is all coming from the parasitology filter. Ex would probably couch it in terms of souls and salvation.”

“I’ll take your filter, thanks. This is what Eric wanted you for,” I said. “To understand how parasites breed. And to stop them. And we did, right? So go us. Nice job.”

“I think this is going to need stitches,” he said.

I looked down at the ruined flesh where the rider’s claws had cut me. When I got dizzy, I looked away.

“Yeah,” I said. “I think you’re right.”

The dog yipped once and rose to its feet. I heard the front door swing open then closed, and Ex came in, his pale eyes wide. Aubrey raised a hand in greeting, and Ex mirrored the gesture with an autonomic air.

“Turned out it was a little hairier than we thought,” I said. “Who knew?”

“The guy out front has a rider,” Aubrey said. “Probably jaette or haugtrold. The original soul’s in the dog. The house belongs to Candace Dorn. The horse is her fiancé, Aaron. He’s a cop. Since there isn’t a SWAT team outside right now, I’m guessing the rider did something to keep the law away while he killed us.”

“And I need to go to a hospital, get stitched up,” I said. I thought I sounded very calm.

“Right,” Ex said, then a moment later, “Okay. I’m on it.”

And that, more or less, was that. Aubrey got me a loose blouse from Candace’s closet to preserve my modesty on the drive. I pressed a towel to my side and tried not to bleed on his minivan. On the way to the emergency room, we concocted a story that we’d been out on a date and got jumped by three muggers. Since it was Boulder, I suggested making them a band of roving neocons, and Aubrey laughed. By the time we staggered into the ER and plopped down to tell our story to the intake nurse, I almost felt human again. Parts of my body ached that I hadn’t known existed, the doctor who looked me over called for about eight different X-rays to see how many of my bones were broken, and the blouse we took from Candace wound up balled into the biohazard can.

When they asked about my health insurance, I took the money out of my pocket. Nine thousand nine hundred and change after pizza and beer. It was enough to cover treatment and a night’s observation. Barely. Even though he was falling down exhausted, Aubrey took point talking to the cops while I drifted in and out of consciousness. The hard, narrow hospital bed was the most comfortable place I’d ever been. Monitors strapped to my chest and arm let out low pongs and chimes.
