Derkhan looked quickly around, saw a cylindrical metal pipe thicker than her thigh. It was long and incredibly heavy, but working urgently, ignoring her tortured muscles, Derkhan hauled it inch by inch across the gap in the fence, wedging it across the tear. She held her arms out, wincing at the acid burn of her muscles. She stumbled back to the cable and tugged it to the edge of the water.

She began to feed it down over the top of the pipe towards the waiting vodyanoi, hauling it as hard as she could. She pulled more and more free from the coils hidden in the heart of the dump and sent the slack towards the water. Finally, Derkhan had lowered it enough for Pengefinchess to kick up, launch herself almost out of the water and grab hold of the dangling end. Her weight pulled several feet of cable down into the water. The edge of the dump listed alarmingly towards the river, but the cable slid across the smooth surface of the pipe, pulling it tight against the fence on either side and rolling smoothly across its top.

Pengefinchess reached up again and hauled, submerging and powering towards the bottom of the river. Kept free of the ensnaring hooks and edges of the inorganic topsoil, the cable came in great gouts, skimming roughly across the surface of the rubbish and plummeting into the water.

Derkhan watched its halting progress, sudden bursts of motion as the vodyanoi hidden at the bottom of the river jack-knifed their legs and swam hard. She smiled, a small and brief moment of triumph, and leaned exhausted against a broken concrete pillar.

There was nothing on the surface of the water to give any hint of the operation below. The great cable slipped in spurts into the water by the riverwall. It plunged absolutely precipitately into the darkness, hitting the surface at ninety degrees. The vodyanoi, Derkhan realized, must be tugging masses of slack into the water first, rather than pulling the end of the wire directly across the river and having it stretch out across the top of the water.

Eventually the cable was still. Derkhan watched quietly, waiting for some sign of the operation under way.

Minutes passed. Something emerged in the absolute centre of the river.

It was a vodyanoi, raising an arm in triumph or salute or signal. Derkhan waved back, squinted to see who it was, to work out if she was being given a message.

The river was very wide, and the figure was unclear. Then Derkhan saw that the arm carried a composite bow, and she realized that it was Pengefinchess. She saw then that the wave was one of curt farewell, and she responded more fulsomely, her brows furrowing.
