The steps led steeply downward, into darkness. Kate went first, holding the torch. Chris followed. They went through a narrow passage, almost a tunnel, that seemed to be man-made, and then came out into a much larger chamber. This was a natural cave. Somewhere high up and off to the left, they saw the pale glimmer of natural light; there had to be a cave entrance up there.
The ground before them still sloped down. Ahead, she saw a large pool of black water and heard the rush of a river. The interior smelled strongly of a sweet-sour odor, like urine. She scrambled over the boulders until she reached the black pool. There was a little sandy margin around the edge of the water.
And in the sand, she saw a footprint.
Several footprints.
"Not recent," Chris said.
"Where's the path?" she said. Her voice echoed. Then she saw it, off to the left, a protruding section of rock wall that had been artificially cut back, making an indentation that allowed you to skirt around the pool and to pass by.
She started forward.
Caves didn't bother her. She'd been in several in Colorado and New Mexico with her rock-climbing friends. Kate followed the path, seeing footprints here and there, and pale streaks in the rock that might have been scratches from weapons.
"You know," she said, "this cave can't be all that long if people used it to carry water to the castle during a siege."
"But they didn't," Chris said. "The castle has another supply of water. They would have been bringing food, or other supplies."
"Even so. How far could they go?"
"In the fourteenth century," Chris said, "peasants didn't think anything about walking twenty miles a day, and sometimes more. Even pilgrims walked twelve or fifteen miles in a day, and those groups included women and old people."
"Oh," she said.
"This passage could be ten miles," he said. And then he added, "But I hope it's not."
Once past the protruding rock, they saw a cut passage leading away from the dark lake. The passage was about five feet high and three feet wide. But at the edge of the dark pool, a wooden boat was tied up. A small boat, like a rowboat. It thunked softly against the rocks.
Kate turned. "What do you think? Walk, or take the boat?"
"Take the boat," Chris said.
They climbed in. There were oars. She held the torch and he rowed, and they moved surprisingly fast, because there was a current. They were on the underground river.
Kate was worried about the time. She guessed they might have only two hours left. That meant they had to get to the castle, reunite with the Professor and Marek, and get themselves into an open space so they could call the machine - all within two hours.
She was glad for the current, for the speed with which they glided deeper into the cavern. The torch in her hand hissed and crackled. Then they heard a rustling sound, like papers ruffled in the wind. The sound grew louder. They heard a squeaking, like mice.
It was coming from somewhere deeper in the cave.
She looked at Chris questioningly.
"It's evening," Chris said, and then she began to see them - just a few at first, and then a hazy cloud, then a torrent of bats flying out of the cave, a brown river in the air above their boat. She felt a breeze from hundreds of flapping wings.
The bats continued for several minutes, and then it was silent again, except for the crackle of the torch.
They glided onward, down the dark river.
Her torch sputtered, and began to go out. She quickly lit one of the others that Chris had carried from the chapel. He had brought four torches, and now they had three left. Would three more torches see them to the surface again? What would they do if the final torch went out and they still had farther - perhaps miles - to go? Would they crawl forward in darkness, feeling their way along, perhaps for days? Would they ever make it, or would they die here, in darkness?
"Stop it," Chris said.
"Stop what?"
"Thinking about it."
"Thinking about what?"
Chris smiled at her. "We're doing okay. We'll make it."
She didn't ask him how he knew. But she was comforted by what he said, even though it was just bluster.
They had been passing through a twisting passageway, very low, but now the cave opened out into a huge chamber, a full-blown cave, with stalactites hanging down from the roof, in some places reaching to the ground, and even into the water. Everywhere the flickering light of the torch faded into blackness. She did, however, see a footpath along one dark shore. Apparently there was a path running the entire length of the cave.
The river was narrower, and moved faster, threading its way among the stalactites. It reminded her of a Louisiana swamp, except it was all underground. Anyway, they were making good time; she began to feel more confident. At this rate, they would cover even ten miles in a few minutes. They might make the two-hour deadline after all. In fact, they might make it easily.
The accident happened so fast, she hardly realized what had occurred. Chris said, "Kate!" and she turned in time to see a stalactite just by her ear, and her head struck the stone hard, and her torch hit it as well - and the burning cloth tip shook free from the stick it was tied to, and in a kind of ghastly slow motion, she watched it fall from her torch onto the surface of the water, joining its reflection. It sputtered, hissed and went out.
They were in total blackness.
She gasped.
She had never been in such darkness before. There was absolutely no light at all. She heard the dripping of the water, felt the slight cold breeze, the hugeness of the space around her. The boat was still moving; they were banging against stalactites, seemingly at random. She heard a grunt, the boat rocked wildly, and she heard a loud splash from the stern.
"Chris?"
She fought panic.
"Chris?" she said. "Chris, what do we do now?"
Her voice echoed.
