The crew room had a second door, and Reacher kept the Glock hard on it until he was sure no one was coming to the rescue. Then he moved on, through that second door, into a long narrow internal hallway that ran away from him to the right, four hundred feet or more. He was beginning to see the layout. The building inside was three parallel chambers, long and thin, like three cigars laid side by side. Corresponding with the three entrances. All full of missiles, way back when. Then empty, just three long echoing vaults. Now colonized and boxed off with plywood. Long central hallways, rooms to the left, rooms to the right, repeated three times over. Which was ironic. What goes around comes around. The modern DoD had started out exactly the same way. Massive expansion at the start of World War Two had left it scrambling. It burrowed into whatever unsuitable old building it could find.

The bad news was, there were a lot of new rooms. Possibly forty per chamber. A total of a hundred and twenty. Plus or minus. Quantico would arrive before he was halfway through the search. Which would be a problem. They would have gotten Delfuenso’s call well before then. She would have told them to land at Whiteman and head north locked and loaded and ready to rock and roll. The crossfire was not going to be pretty.

And the even worse news was plywood was not a good insulator of sound. Which meant the last gunshot had been clearly audible throughout fully one-third of the facility. So Reacher ducked back the way he had come, through the crew room, past the dead guy in the low-slung chair, and into the garage again. The big mechanized doors were still standing open. Like pulled drapes. Beyond them was the hundred-foot entrance tunnel, still with the wrecked pick-up and the two dead guys in it. Reacher found the inside button and hit it. The starter whined and the big diesels caught and the doors began to close. The noise was deafening. Which was exactly what Reacher wanted. Given a choice he liked his rear flank protected, and he wanted plenty of audible warning if someone tried to come in after him.

Then he walked the depth of the garage space and tried the new door in the plywood end partition. It opened into the same kind of long, narrow central corridor. Rooms to the left, rooms to the right. The centre vault, colonized just like the first vault. Some of the doors had blue spots on them. Plastic circles, cut out and glued on. The second room on the left and the second room on the right both had one. That pattern repeated every three rooms as far as the eye could see.

Reacher checked behind him. The door he had come through had two blue spots.

He listened hard and heard nothing. He took a breath and counted to three and set off walking. To the second door on the right. A cheap store-bought item. With a thin chrome handle. And a blue spot, at eye level.

He turned the thin chrome handle. He pushed open the door. A room, of decent size. Empty. No people. No furniture. No nothing, except what had been there all along, which was another original door through the side wall. It was identical to the first two he had seen, with the complex cast frame like a tunnel all its own, and the pale old laminate facing, and the heavy steel handle. Clearly the blue spot meant a way through, side to side. A shortcut, from chamber to chamber. For busy people. The garage door got two blue spots because it had ways through both left and right. The lateral access was an efficiency measure. Both now, apparently, and certainly back when missiles roamed the earth. It would have been time-consuming for a technician to walk the whole length of the building and go outside and then come back in down a different tunnel. Far better to facilitate a little crosstown traffic. Maybe every sixty feet or so. Some guy with a clipboard would have figured that out, long ago. The architects would have gotten to work, with drafting tables and sharpened pencils, and load factors calculated with slide rules and guesswork.

Reacher was in a room on the right-hand side of the row. And just like the door he had seen on the right in the garage, this door on the right was also covered over with thick see-through plastic, which was also stuck down very carefully at the edges with duct tape. Lots of it.

Purpose unknown.

He had two motel keys in his pocket. One from the fat man’s place in Iowa, and one from the FBI’s quarantine spot in Kansas. The fat man’s key was sharper. The tang at the end had been left pretty rough by the key-cutting process. Maybe the key was a replacement. Maybe some guest had headed home with the original still in his pocket, and maybe the fat man’s policy was to use the cheapest services he could find.

Reacher pressed the see-through plastic against the faded old laminate behind it, and he scratched at it with the tip of the key. The key snagged and jumped and made pulls and blisters. The blisters went thin and puffy and the second go-round with the key started a hole in one of them. Reacher got the tip of the key in the hole and sawed away at it, cutting where he could, stretching and tearing where he couldn’t. When the slit reached three inches long he put the key back in his pocket and hooked his fingers in the slit, palms out, and forced his hands apart.

The plastic was tough. Some kind of heavy grade. Not like the tissue-thin stuff he had seen painters use as drop cloths. More like shrink wrap. He had seen people struggling with it. Supermarkets should sell switchblades, right next to the salami. He got the slit about twelve inches long and the tension went out of it. He had to start a new cut with the key. He learned from that experience. He changed his technique, to a rhythmic cut-yank-cut-yank sequence, with the key in his mouth between cuts. Eventually he got it done, more or less all the way from top to bottom, very stretched and ragged, but big enough to force himself through.

He put his arm through the hole and turned the heavy steel handle and pushed the door with his fingertips. Nothing but darkness beyond. And cold air. And a silent acoustic suggestive of vast space and hard walls.

He turned sideways and forced himself through the slit in the plastic, leading with the Glock, then his right foot, then his right shoulder, ducking his head, pulling his left arm and his left foot after him. He used touch and feel, tracing the shape of the cast frame around the door, closing the door behind him, searching for a light switch. He knew there would be one. Those old-time architects with their drafting tables and their sharpened pencils would have been plenty thorough. The electrical plans would have been a whole separate sheaf of blueprints.

He found an electric conduit on the wall. Steel pipe, thickly painted, cold to the touch, covered in dust. He traced it back to a square metal box, maybe four inches by four, with a dimple on its front face, and a cold brass toggle in the dimple.

He turned the lights on.

SEVENTY-THREE

THE THIRD CHAMBER was not subdivided. It was in its original state. It was a tunnel, roughly semicircular in section, forty feet wide, maybe four hundred feet long, just over head high at the side walls, perhaps thirty feet tall at the peak of the vaulted ceiling. It was formed from concrete, poured and cast like the outside, with wood grain showing here and there, with stepped curves, with thin ragged ribs and seams where the formwork had leaked. It was unpainted, but no longer raw. It was mellow and faded and dusty, after many patient decades. It had a blank wall at the far end, and it had blastproof doors at the near end, with a mechanism exactly like the one Reacher had used in the centre chamber.
