Downstairs, the horror film music crescendoed. Upstairs, a series of wails. The kids had stepped into the room where Marcy Hathaway lay sprawled across the floor, her face drenched with a caul of blood, a raw veal cutlet poised on her chest to simulate a sliced-off tongue.

The tour group returned to the hallway. As I squatted there, my heart drummed in my chest. My throat trapped each thin breath. At any second, tonight’s kids would burst into the bedroom.

The door creaked open. Breeze rolled her eyes into her head and lolled her tongue. “Go on inside,” Deborah told the kids, and they filed in. “He hung this daughter. Open your mouth and close your eyes. That’s what he said to all of them. He listened to the snap of this girl’s fifteen-year-old neck.” The kids surrounded the body, fascinated. A little boy with plastic fangs began to cry.

I waited. They spun around, ready to explore the next roomful of carnage. Then I sprang from the corner. They screamed as I swung the broom at them, careful not to touch their heads. They sprinted through the door. I laughed, and Deborah gave me the thumbs-up.

The tours sped by, one every fifteen minutes. After a while, Deborah lost her interest. I selected one member from each group to pick on, usually a girl or boy in a topnotch costume. It disappointed me that none were Martians or robotic aliens, so I wound up picking a favorite in the kid dressed as the Shroud of Turin. He or she wore a black body suit and headpiece, gilded head to toe to resemble the pre-Resurrection Jesus. I gave the “Shroud” a jab of my broom and soft pinches from my glued-on devil’s claws.

With the final tours, the crowd began to change. I had recognized most kids from Sundays at Little River Lutheran, but now more unfamiliar faces drifted through the rooms. Most unrecognizables seemed older. “I think they’re from Hutchinson,” Breeze whispered. The door reopened, and her irises rolled back into her head.

A group of boys looked familiar to me. Six of them filed into the syrupy-smelling bedroom. They had ditched their tour guide. I watched them through the slits in my mask. One belched, his breath visible in the chilly air. He had a blond crew cut and a choker necklace made of minuscule white shells. Another wore overalls and a Reds baseball cap, his teeth gleaming with a row of braces. None of the boys had dressed in a costume.

I emerged from the shadow. Metal-mouth spun and started laughing. “Hey, it’s Lucifer.” The others turned and stared.

The boys surrounded me. I opened my mouth and choked out the word “boo.” All six laughed. Even Breeze Campbell laughed. Her body shook from its noose.

Then the crew cut boy with the shell necklace leaned forward. His green eyes stared into mine.

In that moment, I remembered. I’d known these boys a couple of years previous, during the summer of the missing time and the UFO, the summer I’d started Little League in Hutchinson. I had practiced with them; had listened to them yelling things like “four eyes” and “pansy” and “the only place for you is the bench.” Now, years later, this boy reached toward me, and the memories flooded back-how I hated baseball, how I never returned, even though my father had urged me on, had bragged of the game’s benefits.

Crew cut pushed me against the wall. “Really, unbelievably, incredibly frightening,” he said. His hand shot toward my Satan mask. He tore it from my head, tossing it to the floor.

I felt hairs rip from my scalp. I opened my eyes, and the world had slipped out of focus. My glasses had come off with my mask.

They were laughing, all of them. Breeze’s giggle blistered the air, shrill and pestering, like a blue jay’s screech above their tenors. She was showing off for them. I stepped toward their circle.

My right boot landed on the glasses. I heard the crack, felt them snap like potato chips. I bent to pick them up. Nothing but shards, as thin and sharp as the teeth in a monster’s mouth. I swept the pieces aside and grabbed my mask.

The boys watched me run from the room. I had made a fool of myself, just as I’d done again and again, summers ago. I remembered standing in right field, dropping a pop fly, the older boys taunting me. I staggered downstairs, and my foot slipped on a bloody stair, my arm knocking over the doll and her scissor-gouged face. I passed the hallway, where Deborah and the others stood talking. Without glasses, I could hardly see them. Deborah’s warty face was pressed against Lucas Black’s chest, smudging it with green makeup. “What’s wrong?” she asked.

I didn’t answer. I still heard them upstairs, my old teammates. Their voices echoed bits of sentences: “the decapitated guy in the next room,” “one lousy dollar,” “waiting for us outside in the station wagon.”

Deborah held out her hand. “What’s the matter?”

I sped through the kitchen. It seemed as though the entire town were laughing now, and the noise echoed through the house. I slammed the screen door and ran across the porch, past the row of cars, into the trees.

Thirty minutes later, I sat with Deborah and Breeze in the Campbells ’ car, riding back into Little River. I stared out the window, the black night rushing past, my eyes glazing over. Something had happened to me when I left the Mansion, something I couldn’t quite remember.

I recall bits and pieces. When I sprinted from the house, I saw the moon, orange, almost electric, stalled between feathery clouds like a helium balloon, ready to burst into a million splinters. Without glasses, the world melted from focus. The house and trees seemed under water. I leaned against a tree and felt its knobby trunk pressing into my skin like a column of bones.

I put the mask back on. Behind me, the pipe organ music swelled, softened, swelled again. Most of the kids had gone home. “Let’s call it a night,” an adult said. I kept walking, trying not to cry. My scalp tingled from where the hair had ripped out, and my face pounded from the kid’s hand.

I remember passing the parked cars. Ahead, nothing but air so cold it snapped, and an arena of trees, the bordering saplings leading into towering, ancient cottonwoods and oaks. I wandered through them, their arms whispering and creaking in the wind. I looked up to their blurry branches, as lacy and fragile as spiderwebs.

Back at the house, Leaf roared, no doubt grabbing some kid’s shoulder. A chorus of wails. “Hey, Brian,” Deborah yelled. I was no longer part of that scene. I didn’t stop walking. The Little League boys are in the past, I told myself. Forget them.

In the distance I heard a creek’s murmur. I moved toward the sound, deeper into the trees. Thorns from bushes snagged my cape, oak leaves fell around me, and my galoshes oozed through mud puddles.

A stick cracked behind me. I remember it making that exact sound-crack.

Then I noticed how everything had altered to an unbelievable silence. The crickets, the creek, even the wind had ceased. The quiet made me think of that night on the side of our hill; how I had stood staring up at the sky, a little scared but curiously peaceful, even happy, as the spacecraft hovered its carousel of blue lights above us.

The final thing I remember: In the center of the quiet, another branch snapped. And I turned.

Blur.
