When they’d cleared everything away, Alicia instructed him to stand at one end of the shelf, positioning herself on the opposite side. Peter realized that the back of the shelf was a sheet of plywood, concealing the wall behind it. They pulled the shelf away.

A hatch.

Alicia stepped forward and turned the ring and swung it open. A narrow, tubelike space, with a flight of metal stairs rising in a spiral. Metal crates were stacked against the wall. The stairs vanished in the gloom, some unknowable distance over Peter’s head. The air was stale and choked with dust.

“When did you find it?” he asked, amazed.

“Last season. I got bored one night and started poking around. I figure it’s some kind of escape route left by the Builders. The stairs go straight to a crawl space on the roof.”

Peter gestured toward the crates with his lantern. “What’s in those?”

“That,” she said, smiling mischievously, “is the best part.”

Together they dragged one of the crates out onto the floor of the storeroom. A metal locker, a meter long and half as deep, with the words U.S. MARINE CORPS printed on the side. Alicia knelt to undo the hasps and lifted the lid to reveal six sleek black objects, cradled in foam. It took Peter a few seconds to understand what he was seeing.

“Holy shit, Lish.”

She passed him a weapon. A long-bore rifle, cool to the touch and smelling faintly of oil. It was shockingly light in his hands, as if made of some substance that defied gravity. Even in the dim light of the storage room he could detect the lustrous gleam in the finish of the muzzle. The guns he’d seen were all little more than corroded relics, rifles and pistols the Army had left behind; the Watch still kept some in the Armory, but as far as Peter was aware, all the ammunition had been used up years ago. Never in his life had Peter held anything so clean and new, untouched by time.

“How many are there?”

“Twelve boxes, six guns apiece, a little over a thousand rounds. There are six more crates up in the crawl space.”

All his nervousness was gone, replaced by a lusty hunger to use this wonderful new object in his hands, to feel its power. “Show me how to load it,” he said.

Alicia took the gun from his hands and drew back the bolt and charger. Then she took a magazine of bullets from the box, shoved it into place in front of the trigger guard, pushing forward until it caught, and gave the base two hard taps with her palm.

“Aim it like a cross,” she said, and turned away to demonstrate. “It’s basically the same, only with a lot more kick. Just keep your finger off the trigger unless you mean business. You’ll want to, but don’t.”
