The minerals of the Dradscale estuary made lustre on the water. The brackish slough was full of weed, and Cutter gave a city-dweller’s gape to see a clan of manatees surface and graze.

“Is no safe,” said the helmsman. “Is with-” He gave some obscenity or disgust-noise, and pointed at Fejh. “Up farther. Full of riverpig.”

Cutter tensed at the word. “On,” he said, and pointed his gun. The pilot moved back.

“We no do,” he said. Abruptly he tilted backward over the rail and into the water. Everyone moved and shouted.

“There.” Pomeroy pointed with his revolver. The pilot had surfaced and was heading for one of the islands. Pomeroy tracked him but never fired.

“Godsdammit,” he said as the man reached the little shore. “Only reason the others haven’t gone after him is they can’t swim.” He nodded at the cheering crew.

“They’ll fight back with their fucking hands if we push this,” Ihona said. “Look at them. And you know we won’t shoot them. You know what we have to do.”

So in ridiculous inversion, the hijackers ferried the crew to the island. Pomeroy waved his gun as if carrying out necessary punishment. But they let the sailors off, and even gave them provisions. The captain watched plaintively. They would not let him go.

Cutter was disgusted. “Too fucking soft,” he raged at his friends. “You shouldn’t have come if you’re so soft.”

“What do you suggest, Cutter?” Ihona shouted. “You make them stay if you can. You ain’t going to kill them. No, maybe we shouldn’t have come, it’s already cost us.” Pomeroy glowered. Elsie and Fejh would not look at Cutter. He was suddenly fearful.

“Come on,” Cutter said. He tried not to sound wheedling or scornful. “Come on. We’re getting there. We’ll find him. This bloody journey’ll end.”

“For someone so known not to give a damn,” Ihona said, “you’re risking a lot for this. You want to be careful, people might think you ain’t what you like to think.”

The Dradscale was wide. Ditches and sikes joined it, channelling in dirty water. It was unbending for miles ahead.

On the east bank, dry hills rose behind the mangroves, wind-cut arids. It was a desert of cooked mud, and way beyond it was Shankell, the cactus city. On the west the land was altogether harsher. Above the fringe of tidal trees was a comb of rock teeth. A zone of vicious karst, an unbelievable thicket of edged stone. By Cutter’s imprecise documents it stretched a hundred miles. His maps were scribbled with explorers’ exhortations. Devils’ nails said one, and another Three dead. Turned back.

There were birds, high-shouldered storks that walked like villains. They flew with languid wingstrokes as if always exhausted. Cutter had never suffered in so brute a sun. He gaped in its light. All of them were pained by it, but Fejh of course most of all, submerging again and again in his stinking barrel. When eventually the water around them was saltless he dived with relief and refilled his container. He did not swim long: he did not know this river.

The man they followed must have been a vector of change. Cutter watched the riverbanks for signs that he had passed.

They steamed through the night, announcing themselves with soot and juddering. In the hard red light of dawn the leaves and vines dandled in the current seemed to deliquesce, to be runoff streams of dye, matter adrip into meltwater.

While the sun was still low the Dradscale widened and bled into a pocosin. The marsh-lake was met by the end of the karst, uncanny fingerbones of stone. The Akif slowed. For minutes, its motor was the only sound.

“Where now, Cutter?” someone said at last.

Something moved below the water. Fejh leaned up half out of his barrel.

“Dammit, it’s-” he said but was interrupted.

Things were surfacing ahead of the Akif, broad-mouthed heads. Vodyanoi bravos waving spears.

The captain came upright and shrieked. He shoved down on his throttle, and the water-bandits scattered and dived. Fejh upset his barrel, spilling dirty water. He leaned out and yelled in Lubbock at the vodyanoi below, but they did not answer.

They came up again, burst out of the water and for a moment were poised as if they stood upon it. They threw spears before they fell. Spumes of water arced from below their outflung arms so that their shafts became harpoons, riding it. Cutter had never seen such watercræft. He fired into the water.

The captain was still accelerating. He was going to drive the Akif onto the shore, Cutter realised. There was no time to moor.

“Brace!” he shouted. With a huge grinding the boat rode the shallow bank. Cutter pitched over the prow and landed hard. “Come on!” he said, rising.

The Akif jutted like a ramp. The antelopes’ pen had broken and, tethered to one another, they were hauling off in a dangerous mass of hooves and hornstubs. Fejh vaulted the listing rail. Elsie had hit her head, and Pomeroy helped her down.

Ihona was cutting the captain’s bonds. Cutter fired twice at oncoming swells. “Come on!” he shouted again.

A spire of water rose by the broken boat. For an instant he thought it some freakish wave, or watercræft of an astonishing kind, but it was more than twenty feet high, a pillar of utterly clear water, and from its top jutted a vodyanoi. He was a shaman, riding his undine.

Cutter could see the vessel distorted through the water elemental’s body. Its thousands of gallons pushed down on the boat with strange motion, and bucked it, and Ihona and the captain fell down the sloping deck toward it. They tried to rise but the water of the undine flowed up and lapped at their feet then broke, a wave, and engulfed them. Cutter shouted as his comrade and her prisoner were buffeted into the undine’s belly. They kicked and clawed, trying to swim out but which way was out? The undine gave its innards currents that kept them in its core.

Pomeroy bellowed. He fired, and Cutter fired, and Fejh let an arrow go. And all three missiles hit the elemental with splashes like dropped stones, and were swallowed up. The arrow was visible, vortexing in the liquid thing, coiling down to be voided like shit. Again Cutter fired, this time at the shaman atop the monstrous water, but his shot was wide. With idiot bravery Pomeroy was pummelling the undine, trying to tear it apart to get at his friend, but it ignored him, and his blows raised only spray.

Ihona and the captain were drowning. The undine poured itself into the cargo hold, and the shaman kicked down into its bowels. Cutter screamed to see Ihona’s still-moving body carried in the matter of the undine belowdecks and out of sight.

The vodyanoi were all over the Akif. They began to throw spears again.

Water poured up out of the boat, the undine geysering from the hold, and it carried within it engine parts-iron buoyed on its strange tides. And rolling like motes were the bodies of its victims. They moved now only with the water that bore them. Ihona’s eyes and mouth were open. Cutter saw her only a moment before the elemental came down in a great arch into the lake, water in water, carrying its loot and dead.

All the travellers could do was curse and cry. They cursed many times, they howled, and moved at last into the grasslands, away from the boat, away from the rapacious water.

At night they sat exhausted in a motte of trees beside their sables and watched Elsie. The moon and its daughters, the satellites circling it like tossed coins, were high. Elsie, cross-legged, looked at them, and Cutter was surprised to see her calm. She moved her mouth. A shirt was tied around her neck. Her eyes unfocused.

Cutter looked beyond her through the canebrake at the veldt. In the night light the tambotie trees and ironthorns were silhouetted like assassins. Baobabs stood thickset with their splintered crowns.
