The gun jumped in my hand as it went off, but in that instant, the flash lit up her terrified face, an unfinished scream drowned out by the bang. A spray of blood flicked up over my hand as her face seemed to cave in on itself, staining the dark jacket I wore…and the edge of the white cuff beneath it.

The boy died the same way, only Rob didn’t bother to even take his hood off before he ended his life. The bodies were lifted into the Dumpsters. I shrank back and away from the scene, watching it grow smaller, and smaller, and smaller until the dark, cloudy haze of Rob’s mind swallowed it whole.

I tugged myself free, coming up from the inky pool with a sharp gasp.

Rob released my arm instantly, but Cate dove forward and would have taken his place if I hadn’t raised both hands to stop her.

“Are you all right?” she asked. “You’ve gone pale.”

“I’m okay,” I said, trying to keep my voice calm and steady. “Still feeling a little woozy from the medicine.”

Martin let out an annoyed sigh behind me. He was hopping from foot to foot, grumbling impatiently. He slid a suspicious eye in my direction, and for half a heartbeat I was afraid he knew exactly what had just happened. But, no—connections like that were fast, and lasted only a few seconds, no matter how long it felt to me.

I kept my eyes on the ground, carefully avoiding both the adults’ faces. I couldn’t bring myself to look at Rob, not after seeing what he had done—and I knew if I looked at Cate, I’d give myself away in an instant. She’d ask me what was wrong, and I wouldn’t be able to lie, not convincingly. I’d have to tell her that her boyfriend or partner or whatever he was had left the brains of two kids splattered all over an alleyway.

Rob tried to offer me a plastic water bottle from the front seat, his mouth stretched in a thin line. My eyes settled again on the tiny red flecks staining his cuff.

He killed them. The words echoed through my head. It could have happened days, maybe even weeks ago, but it didn’t seem likely. Wouldn’t he have changed his shirt, or tried to clean it off? And then he came here—to kill us, too?

Rob smiled at me, all of his teeth showing. Smiled. Like he hadn’t just snuffed out two lives at point-blank range and watched the rain carry their blood into the gutters.

My hands were shaking so hard now that I had to fist them around the backpack to keep him from noticing. I thought I had escaped the monsters, that I’d left them locked up behind an electric fence. But the shadows were alive, and they had chased me here.

I’m next.

I swallowed the scream working its way up my throat, and smiled right back at him, my insides twisting. Because I had no doubt, not one single wisp of uncertainty, that if he knew what I had just seen, Cate would spend the next few days bleaching my blood out of his shirt, too.
