the right size and inserted it in the keyway, applying tension in the unlocking direction. Lock picking, she knew, was basically a job of finding the mechanical defects of a particular lock: the individual pins were never machined to precisely the same size, there were always slight variations between them that could be exploited. Next, she inserted a pick and gingerly tested the wards, looking for the tightest fit, which would signify the thickest pin. Since the thickest pin of a lock binds first when a turning force is applied, it was important to pick the pins in order of fattest to thinnest. There it was: the pin that bound the most. Carefully, using the pick, she raised it until she felt it set at the shear line. Then she moved to the next thinnest pin and repeated the process, and then once again, careful always to maintain tension. At last, the driver pin set with an audible click; she gave a yank and the lock popped open.
Corrie stood back, unable to suppress a small smile of pride. She wasn’t particularly fast at picking locks—and there were lots of other techniques, like “scrubbing” and “raking,” that she hadn’t mastered—but she was competent. Too bad it was a skill Pendergast would disapprove of. Or would he?
Putting the lock-picking tools back in her pocket, she removed the padlock and placed it to one side. The door squeaked open on rusty hinges; she moved through the entrance, then hesitated. She stood in the darkness a moment, wondering if she should turn on the lights or use her flashlight. If Winifred Kraus showed up, the lights would be a dead giveaway. But then she recollected herself. It was three o’clock in the afternoon, past time for the last tour of the day according to the sign; and besides, Corrie was positive there hadn’t been any tours at all since Pendergast had been forced to take one. The old busybody wasn’t going to stir out of her house in a rising storm. Also, the watchful darkness was getting on her nerves. Better to save her batteries.
She felt along the damp stone wall, found the light switch, flicked it on.
It had been years since she’d been in the cave. Her father had taken her there once, when she was six or seven, not long before he’d run off. For another moment she remained still, looking down into the yawning tunnel. Then she began to descend the limestone steps, her waffle-stompers echoing against the stone.
After a long descent, the staircase gave onto a wooden boardwalk that disappeared between stalagmites and stalactites. Corrie had forgotten just how strange the place was. As a kid going there, she’d been surrounded by adults. Now she was alone in the silence. She walked forward hesitantly, wishing her shoes didn’t make such a hollow sound against the walkway. Bare bulbs, hanging from the uneven ceiling far overhead, threw spectral shadows against the walls. A forest of stalagmites, like jagged, giant spears, rose on both sides. There was no sound in the vast empty space but her footsteps and the distant drip of water.
Maybe coming here hadn’t been such a good idea.
She shook off the feeling of dread. There was no one here. The puddles on the wooden walkway had a skimming of silt that registered her footprints. It was clear—just as it had been outside the iron door—that no one had walked through in days. The last person in here was most likely Pendergast himself being dragged through the tour.
Corrie hastened through the first cavern, ducked under a narrow opening, and entered the second cavern. Immediately, she remembered what it was called: the Giant’s Library. She remembered that, as a kid, she’d thought the place really
But always, the silence felt watchful, somehow, and the dim light oppressive, and she hurried on. She passed the Bottomless Pit and reached the Infinity Pool, which glowed a strange green in the light. This was the farthest point of the tour; here the walkway looped back toward the Krystal Kathedral. Beyond lay only darkness.
Corrie turned on her flashlight and probed the darkness beyond the boardwalk, but could see nothing.
She climbed over the wooden rail and stood at the edge of the pool. The walls of the caverns she’d passed through had been devoid of any passageway or portal. If anything lay beyond, she’d have to go through the pool to find it.
Corrie sat on the rail and unlaced her shoes, took them off, pulled off the socks and stuffed them into her shoes, and tied the laces together. Holding the shoes in one hand, she stuck a toe in the pool. The water was shockingly cold and deeper than it looked. She waded across as quickly as she could and pulled herself out the other side. Now her legs were wet, damn it. Barefooted, she clambered down the far side of the pool and shone her light into the darkness at its base. Here she could see a low tunnel going off to the right. The ground was soft limestone, well worn down by old comings and goings. She was on the right track.
She sat on a hump of limestone and pulled her socks over her wet feet, then laced up the heavy waffle- stompers. She should’ve thought to wear old sneakers.
She stood up and approached the tunnel. She had to duck—it was about five feet high—and as she progressed the ceiling got lower. Water trickled along the bottom. Then the ceiling rose again and the tunnel bent sharply to the right.
Her light shone on an iron door, padlocked just like the one at the front of the cave.
Once again, she took out her lock-picking tools and went to work. For some reason—perhaps because of the poor light, perhaps because her fingers felt unaccountably thick and uncoordinated—this lock took much longer. But after several minutes, she felt the unmistakable give as the driver pin set. Silently, she placed the lock to one side and swung the door open.
She paused in the entranceway, shining her light around cautiously. Ahead, a dark passageway cored through the living rock of the cave, its walls smooth and faintly phosphorescent. She started forward, following it for perhaps a hundred feet, flashlight playing around the walls, until it suddenly widened into a chamber. But this space had none of the vastness or majesty of the earlier caverns, just a few stubbly stalagmites rising from the rough uneven floor. The air was chill and close, and there was a smell, an unusual smell: smoke. Old smoke, and something else. Something foul. She could feel the cool flow of air coming from the open door, stirring the hairs on the nape of her neck.
This had to be it: the old moonshine still.
She advanced into the gloom, and as she did so her flashlight picked up something at the far end—a dull gleam of metal. She took another step, then another. There it was: an old pot still, an almost cartoonlike relic from a vanished era, with an enormous copper cauldron sitting on a tripod stand and the ashes of an old fire underneath. Stacked on a shelf above the floor were some split logs. The top of the cauldron, with its long coil of copper tubing, had been removed and now lay on the floor, partially crushed. There were several smaller pots and cauldrons scattered about.
She paused to sweep the room with her light. Off to one side was a table with a couple of glasses on it, one broken. Pieces of a chair lay on the floor beside a rotting playing card; an ace, Corrie noticed. In one corner stood a
