So what in hell could have killed this man?

He shivered again and hated the sight of this perfect set of bones and hurriedly stepped over them, eager to get away. He went farther down, and the fissure became two. Which direction? The smoke had been a bad idea. By now it had dispersed so he could not see which way it was drifting, and it had dulled his sense of smell so he could not even detect its path with that. His torch was burning low in the damp air, flickering sporadically in no particular direction. What was left to him was a kid's game, moistening his finger in his mouth, holding it at one opening, then the other. He felt the breeze slightly cool on the wet of his finger going to the right, and uncertainly he followed down, sometimes forced to squeeze through, occasionally stooping. His torch was burning lower in the damp air all the time. He came to another set of openings and wished that he had rope or string to lay out behind him so that if he became lost he would be able to find his direction back.

Sure, and wouldn't you like a flashlight too? And a compass? Why don't you go on over to the hardware store and buy them?

Why don't you forget the jokes?

The breeze seemed to the right again, and as he moved along, the passage grew more complicated. More twists and turns. More offshoots. Soon he could not remember how he had come to where he was. The skeleton seemed a long confusing distance behind him. It was strangely funny to him that the moment he considered turning around and retracing his steps, he realized he was lost and could not do that. He did not actually want to return yet, he was just considering it, but all the same he would have preferred the option of being able to go back if the breeze suddenly ended. It was extremely faint even so, and he wondered if he had missed some crack in the rock where it seeped out of the hill. God, he could wander here until he died, end up like those bones.

The murmur saved him from panic, and he thought it was them coming, but how could they find him in this maze, and then he recognized the distant sound of water rushing. Before he knew, he had increased speed toward it, at last a perceptible goal in mind, shouldering against walls, staring into the darkness beyond his light.

Then the sound was gone and he was alone again. He slowed and stopped, leaning against a wall, hopeless. There had been no sound of rushing water. He had imagined it.

But it had seemed so real. He could not believe that his imagination could trick him so completely.

Then what had happened to the sound? If it was so real, where was it?

A hidden turn, he realized. In his haste to reach the sound, he had failed to check for other entrances in the rock. Go back. Look. And as he did, he heard it once more, and found the opening, on the blind side of a curve, and slipped into it, the sound louder as he went.

It was deafening now. The flames of his torch diminishing to go out, he arrived where the fissure came onto a ledge — and below him, far down, a stream was swirling through a hole in the rock, roaring down into a channel and away under a shelf. Here. This had to be where the breeze was going.

But it wasn't. The water foamed up over the shelf and there was no space for air to be sucked through. But still he felt the breeze strong here; there had to be another exit close by. His torch hissed, and he glanced around frantic to memorize the shape of the ledge, and then he was in darkness, a darkness that was more complete and solid than any he had ever stood in, made overpowering by the cascade of water below into which he might easily fall if he did not grope his way with care. He tensed, waiting to get used to the dark. He never did get used to it. He began to lose his balance, swaying, and at last he went down on his hands and knees, crawling toward a low passage at the end of the ledge that he had seen just before his light sputtered out. To go through the hole he had to slip flat on his belly. The rock there was jagged. It tore his clothes and scraped his skin and twisted his ribs until he repeatedly groaned.

Then he screamed as well. From something more than his ribs. Because as he came blind through the hole into a chamber where he had room to lift his head, he reached out his hand to claw himself forward, and fingered mush. A drop of wet muck plopped onto his neck, and something bit his thumb, and something tiny darted up his arm. He was lying in thick scum that was soaking through his two ripped shirts streaking his belly. He heard squeaking above him, and the cardboard ruffle of wings, and Jesus Christ, it was bats, he was lying in their shit, and what were by now a half-dozen tickly things scurrying over his hands, nibbling, they were beetles, the scavengers that feasted off bat dung and sick bats fallen to the floor. They could strip a carcass clean, and they were piercing the flesh of his arms, as he wriggled insanely backward through the hole, Jesus Christ, swatting them off his hands and arms, bumping his head, wrenching his side. Jesus, rabies, a third of any bat colony was rabid. If they woke and sensed him they might attack and cover him biting while he screamed. Stop it, he told himself. You'll bring them to you. Stop screaming. Already wings were flapping. Christ, he couldn't help it, screaming, wriggling back, and then he was out on the ledge, sweeping his hands and arms, rubbing, making sure and double-sure they all were off, still feeling their many-legged tickles on his skin. They might follow, he suddenly thought, scurrying back from the low entrance to the hole, disoriented in the dark, one leg toppling off the ledge, dangling. The fright of his near fall jolted him. He lurched in the opposite direction and bumped against a wall of rock and shook, hysterically wiping the mushy dung off his hands onto the rock, pawing at the slime on his shirt to get the stuff off. His shirt. Something was in there scratching on his skin. He shoved in a hand, grabbing it, snapping its brittle back so he felt its soft wet insides on his fingers as he threw it violently toward the sound of the cascade.

Bats. A pest hole. Disease. The putrid smell of the dung stinging his nose and throat. That's how the guy who worked the mine had died. Rabies. He had been bitten unknowingly, and days later the disease came driving him out of his mind; he wandered crazily through the forest, into the tunnel, out of the tunnel, in once more and down into the fissure, in and around until he crumpled and died. The poor bastard, he must have thought it was the loneliness that was getting to him. At the start anyhow. And when he became delirious, he was too far gone to help himself. Or maybe toward the end he knew he couldn't be helped and went down into the fissure where he could die without being a danger to anyone.

Maybe nothing. What in hell do you know about it? If he had rabies, then he would have hated water, even the smell of it, the idea of it, so he would never have gone down into the dampness of the fissure. You're just imagining that it'll be you who dies that way. If they don't eat you first.

What are you talking about? The bats can't eat you. Not the kind around here.

No, but the beetles.

He was still shaking, struggling to calm himself. The breeze had been strong in the chamber. But he could not go that way. And he did not know how to return to the upper tunnel. He had to face it. This was it. He was stuck.

Except that he could not let himself believe that he was stuck. He had to fight panic and pretend there was a way out; he had to sit against the wall of rock and try to relax and maybe if he thought long enough he might actually discover an escape. But there was only one escape and he knew it: toward the breeze into the bats' den. He licked his lips and took a sip of iron-pipe tasting water from his canteen. You know you have to go in there with the bats don't you, he told himself. It's either that or sit here and starve and get sick from the damp and die.
