They followed him into a large, high-ceilinged room. The windows were sealed by more concrete blocks, with narrow slits at the top for ventilation, through which issued a yellow-tinted glow of fading daylight. The air smelled of dust and animals. A miscellaneous assemblage of tools and building supplies was pushed against the walls: sacks of concrete, plastic troughs and hoes encrusted with cement, a wheelbarrow, coils of rope and chain. The bays where the engines had once been were empty. Now the area served as a makeshift stable, with half a dozen stalls and tack hung on the boards. Along the far wall, a flight of wooden stairs ascended into nothing—the second floor was gone.

“Cots in the back,” Hollis explained. He had knelt to fill a lantern from a plastic jug. Peter saw the liquid’s pale golden color and recognized the smell. Not alcohol: petroleum. “All the comforts of home. There’s a kitchen and bath, too, though there’s no running water and the chimney’s sealed.”

Alicia was leading the horse inside. “What about this door?” she asked.

Hollis lit the lantern with a match, paused to adjust the wick, and passed it to Mausami, who was standing beside him. “Hightop, give me a hand.”

Hollis retrieved a pair of wrenches and passed one to Caleb. Hanging from the joists over the front entrance, suspended by a pair of blocked chains, was a barricade of thick metal plates, framed by heavy timbers. They lowered it into position and bolted it to receivers set in the jamb, sealing themselves inside.

“Now what?” Peter asked.

The big man shrugged. “Now we wait till morning. I’ll take first watch. You and the others should sleep.”

In the back room were the cots Hollis had spoken of, a dozen mattresses on sagging springs. A second door led to the kitchen and bathroom, with a row of rust-stained sinks below a cracked mirror and four toilet stalls. All of the windows were sealed. One of the toilets had been pulled out and now sat, its bowl tipped forward like the face of a drunken man, in the far corner of the room. In its place was a plastic bucket and, on the floor beside it, a pile of old magazines. Peter picked up the top one: Newsweek. On the cover was a blurry photo of a viral. There was something oddly flattened about the image, as if it had been taken from a great distance and very close at the same time. The creature was standing in some sort of alcove, in front of a device with the letters ATM written at the top. Peter didn’t know what this was, though he’d seen one like it in the mall. On the ground behind the viral lay a single, empty shoe. The two-word caption said, BELIEVE IT.

He returned with Alicia to the garage. “Where are the rest of the supplies?” he asked Hollis.
