“Ha-ha!” I said in the same voice, double-tapping my own fear with the character’s staccato laugh. A thought came shining through my head: Maybe I can’t stop this thing from coming at my back.

But I can choose which way I turn it.

I struggled to my feet and started town the aisle, spinning with every step, whirling-dervish style. The whole time, I heard myself spewing Pee-wee Herman’s cartoony laugh—which, in retrospect, was possibly the creepiest thing to hit my ears that night.

I hit the door with a hip and an elbow and blew through it, still spinning, out into the parking lot. Once there, I realized that my escape plan did not have a part two. It hadn’t been concerned with getting me any farther than the doors of the store.

I’d achieved the objective. Now what?

The darkened parking lot was a mass of shadows. The nearest lights were a hundred yards away, and seemed somehow dimmer, more orange than they should have been. There was a heaviness in the air and a faint, faint stench of death and rot. Had that been something the creature had done? Had that been what it meant when it said it had made sure of our privacy?

Stan was in the parking lot, out between the two islands housing the convenience store’s gas pumps. He looked like a man who was trying to run in slow motion. His arms were moving very slowly, his legs bent as if sprinting, but his pace was much slower than a walk, as if he’d been trying to run through a rice paddy filled with peanut butter. He was looking over his shoulder at me, and his face was distorted with terror, a horrible mask that hardly looked human in the shadow-haunted night.

I began to run toward him on pure instinct. Herd instinct, really, operating on the assumption that there was greater safety in numbers. My feet pounded the parking lot’s asphalt at normal speed, and his eyes widened with almost comical slowness and amazement as I ran toward him.

“Is that what you are?” came the creature’s voice, from no direction and from all of them. “One of them? One of the swarm that infests this world?” The origin point of the voice changed, and I suddenly felt hot, stinking breath right on the back of my neck. “I expected better of a pupil of DuMorne.”

I whirled, throwing my arms up defensively. I had time to see everything in the reflection of the convenience store’s broad front windows.

He Who Walks Behind emerged from the shadows in front of the terrified Stan. Broad, horrible arms wrapped around him, crushing him as easily as a man picking up a child. Another limb, maybe a tail or some kind of tentacle, covered in the same growth-fur-scales as the rest of the creature, joined the two arms, so that Stan was wrapped at the shoulders, at the bottom of the ribs, and at the hips.
