“We’ll go out over the wharf,” the little captain said.
Nirgal nodded. “What’s your name?”
“Bly’s the name. B-L-Y.”
“I’m Nirgal.”
The man nodded once.
“So this used to be the docks?” Nirgal asked.
“This was Faversham. Out here were the marshes— Ham, Magden— it was mostly marsh, all the way to the Isle of Sheppey. The Swale, this was. More fen than flow, if you know what I mean. Now you get out here on a windy day and it’s like the North Sea itself. And Sheppey is no more than that hill you see out there. A proper island now.”
“And that’s where you saw. . . .” He didn’t know what to call her.
“Your Asian grandma came in on the ferry from Vlissingen to Sheerness, other side of that island. Sheerness and Minster have the Thames for streets these days, and at high tide they have it for their roofs too. We’re over Magden Marsh now. We’ll go out around Shell Ness, the Swale’s too clotted.”
The mud-colored water around them sloshed this way and that. It was lined by long curving trails of yellowing foam. On the horizon the water grayed. Bly spun the wheel and they slapped over short steep waves. The boat rocked, and in its entirety moved up and down, up and down. Nirgal had never been in one before. Gray clouds hung over them, there was only a wedge of air between the cloud bottoms and the choppy water. The boat jostled this way and that, bobbing corklike. A liquid world.
“It’s a lot shorter around than it used to be,” Captain Bly said from the wheel. “If the water were clearer you could see Sayes Court, underneath us.”
“How deep is it?” Nirgal asked.
“Depends on the tide. This whole island was about an inch above sea level before the flood, so however much sea level has gone up, that’s how deep it is. What are they saying now, twenty-five feet? More than this old girl needs, that’s sure. She’s got a very shallow draft.”
He spun the wheel left, and the swells hit the boat from the side, so that it rolled in quick uneven jerks. He pointed at one gauge: “There, five meters. Harty Marsh. See that potato patch, the rough water there? That’ll come up at midtide, looks like a drowned giant buried in the mud.”
“What’s the tide now?”
“Near full. It’ll turn in half an hour.”
“It’s hard to believe Luna can pull the ocean around that much.”
“What, you don’t believe in gravity?”
“Oh, I believe in it— it’s crushing me right now. It’s just hard to believe something so far away has that much pull.”
“Hmm,” the captain said, looking out into a bank of mist blocking the view ahead. “I’ll tell you what’s hard to believe, it’s hard to believe that a bunch of icebergs can displace so much water that all the oceans of the world have gone up this far.”
“That is hard to believe.”
“It’s amazing it is. But the proof’s right here floating us. Ah, the mist has arrived.”
“Do you get more bad weather than you used to?”
The captain laughed. “That’d be comparing absolutes, I’d say.”
The mist blew past them in wet long veils, and the choppy waves smoked and hissed. It was dim. Suddenly Nirgal felt happy, despite the unease in his stomach during the deceleration at the bottom of every wave trough. He was boating on a water world, and the light was at a tolerable level at last. He could stop squinting for the first time since he had arrived on Earth.
The captain spun his big wheel again, and they ran with the waves directly behind them, northwest into the mouth of the Thames. Off to their left a brownish-green ridge emerged wetly out of greenish-brown water, buildings crowding its slope. “That’s Minster, or what’s left of it. It was the only high ground on the island. Sheerness is over there, you can see where the water is all shattered over it.”
Under the low ceiling of streaming mist Nirgal saw what looked like a reef of foaming white water, sloshing in every direction at once, black under the white foam. “That’s Sheerness?”
“Yeah.”
“Did they all move to Minster?”
“Or somewhere. Most of them. There’s some very stubborn people in Sheerness.”
Then the captain was absorbed in bringing the boat in through the drowned seafront of Minster. Where the line of rooftops emerged from the waves, a large building had had its roof and sea-facing wall removed, and now it functioned as a little marina, its three remaining walls sheltering a patch of water and the upper floors at the back serving as dock. Three other fishing boats were moored there, and as they coasted in, some men on them looked up and waved.
