Vimes opened his eyes. After a while, moving his arm slowly, because of the pain, he found his face and checked that his eyelids were, indeed, open.

What bits of his body weren’t aching? He checked. No, there seemed to be none. His ribs were carrying the melody of pain, but knees, elbows, and head were all adding trills and arpeggios. Every time he shifted to ease the agony, it moved somewhere else. His head ached as if someone was hammering on his eyeballs.

He groaned, and coughed up water.

Gritty sand was under him. He could hear the rush of water somewhere nearby, but the sand under him was merely damp. And that didn’t seem right.

He risked turning over, a process that extracted a considerable amount of groan.

He could remember the icy water. There had been no question of swimming. All he’d been able to do was roll himself into a ball as the water threw and scraped and banged him through the bagatelle board of Koom Valley. He’d gone over an underground waterfall once, he was sure, and had managed to suck in a breath before being whisked onward. And then there was depth, and pressure, and his life started to unroll before his eyes, and his last thought had been please, please, can we skip the bit with Mavis Trouncer…

And now he was here on an invisible beach, totally out of the water? But this place surely didn’t have tides!

So someone was somewhere in the blackness, watching him. That was it. They’d pulled him out and now they were watching him…

He opened his eyes again. Some of the pain was gone, leaving stiffness as payment. He had a feeling that time had passed. The darkness pressed in on all sides, thick as velvet.

He rolled back with more groans, and this time managed to push himself onto his hands and knees.

“Who’s there?” he mumbled, and, very carefully, got to his feet.

Being upright seemed to shake his brain into gear again.

“Anyone there?” The darkness swallowed the sound. Anyway, what would he have done if something had said “Yes!”

He drew his sword and held it out in front of him as he shuffled forward. After a dozen steps, it clinked against rock.

“Matches,” he mumbled. “Got matches!”

He found the wax bundle and, working his clammy fingers slowly, drew out one match. Scraping the wax off the head with his thumb, he struck it against the stone.

The glare hurt his eyes. Look, quick! Flowing water, smooth sand, hand-and footprints coming out of the water, one set only? Yes. Walls looked dry, small cave, darkness over there, way out…

Vimes limped toward the oval entrance as quick as he could while the match spat and fizzed in his hand.

There was a bigger cave here, so big that the blackness in it seemed to suck all the light from the match, which scorched his fingers and died.

The heavy darkness closed in again, like curtains, and now he knew what the dwarfs meant. This wasn’t the darkness of a hood, or a cellar, or even of their shallow little mine. He was a long way below the ground here, and the weight of all that darkness bore down on him.

Now and again, a drop of water went plink into some unseen pool.

Vimes staggered onwards. He knew he was bleeding. He didn’t know why he was walking, but he did know that he had to.

Maybe he’d find daylight. Maybe he’d find a log that had been washed in here, and float his way out. He wasn’t going to die, not down here in the dark, a long way from home.

A lot of water was dripping in this cavern. A lot of it was going down his neck right now, but there were plinks on every side. Hah, water trickling down your neck and odd noises in the shadows…well, that’s when we find out if we’ve got a real copper, right? But there were no shadows here. It wasn’t light enough.

Perhaps that poor sod of a dwarf had wandered through here. But he found a way out. Maybe he knew the way, maybe he had a rope, maybe he was young and limber…and so he’d got out, dying on his feet, and tucked away the treasure, out of the way, and then went down the valley, walking through his grave. That’s how it could take people. He remembered Mrs. Oldsburton, who went mad after her baby died, cleaning everything in the house, every cup, wall, ceiling, and spoon, not seeing anybody or hearing anything, just working all day and all night. Something in the head went click, and you found something to do, anything, to stop yourself thinking.

Best to stop thinking that the way out the dwarf had found had been the one Vimes had dropped in by, and he had no idea where that was now.

Maybe he could simply jump back in the water, knowing what he was doing this time, and maybe he’d make it all the way down to the river before the turbulent currents battered him to death. Maybe he—

Why the hell had he let go of that rope? It had been like that little voice that whispers “Jump” when you’re at a cliff edge, or “Touch the fire.” You didn’t listen, of course. At least most people didn’t, most of the time. Well, a voice had said “Let go,” and he had…

He shuffled on, aching and bleeding, while the dark curled its tail around him.
