Nirgal shook his head. The air was like a greenhouse gone bad. The light, so dim. He could barely get back up the stairs. Bly had made their farewells. Back into the bright mist. Back onto the boat. Chasing wisps. A ruse, to get him out of Bern. Or an honest mistake. Or a simple fool’s errand.

Bly sat him down in the boat’s cabin, next to a rail. “Ah well.”

Pitching and yawing, through the mist, which closed back down. Dark dim day on the water, sloshing through the phase change where water and mist turned into each other, sandwiched between them. Nirgal got a little drowsy. No doubt she was back on Mars. Doing her work there in her usual secrecy, yes. It had been absurd to think otherwise. When he got back he would find her. Yes: it was a goal, a task he gave himself. He would find her and make her come back out into the open. Make sure she had survived. It was the only way to be sure, the only way to remove this horrible weight from his heart. Yes: he would find her.

Then as they motored on over the choppy water, the mist lifted. Low gray clouds rushed overhead, dropping swirls of rain into the waves. The tide was ebbing now, and as they crossed the great estuary the flow of the Thames was released full force. The gray-brown surface of the water was broken to mush, waves coming from all directions at once, a wild bouncing surface of foamy dark water, all carried rapidly east, out into the North Sea. And then the wind turned and poured over the tide, and all the waves were suddenly rushing out to sea together. Among the long cakes of foam were floating objects of all kinds: boxes, furniture, roofs, entire houses, capsized boats, pieces of wood. Flotsam and jetsam. Bly’s crew stood on the deck, leaning over the rails with grapnels and binoculars, calling back to him to avoid things or to try to approach them. They were absorbed in the work. “What is all of this stuff?” Nirgal asked Bly.

“It’s London,” Bly said. “It’s fucking London, washing out to sea.”

The cloud bottoms rushed east over their heads. Looking around Nirgal saw many other small boats on the tossing water of the great rivermouth, salvaging the flotsam or just fishing. Bly waved to some as they passed through, tooted at others. Horn blasts floated on the wind over the gray-speckled estuary, apparently signaling messages, as Bly’s crews commented on each.

Then Kev exclaimed, “Hey what’s that now!” pointing upstream.
