Now and then the boat would reach a freak wave and leap over it. Remi would flex her knees to take the jump like a skier, cling to the steering wheel, and then duck to avoid the splash that the wind sent back at them. Sam stood close to her and said, “You can slow down a little bit now. If they lose sight of us this early, they might give up. We want them fully committed.”

“Aye, aye,” she said.

She drove on, keeping their pursuers barely in sight, until Sam said, “All right. Now go into Vermilion Lake.”

She turned right, sped across the open water, and then headed for the bayous. As she shot into the first narrow, winding channel, she gradually pulled back the throttle. “Hey, make yourself useful,” she said. “Get up to the bow and make sure I don’t hit anything that’s alive or puts holes in boats.”

“Happy to,” Sam said. He got up on the foredeck and pointed in the direction that was clearest. He studied the water for snags and shallow spots and kept her out of them. The water was dark and nearly opaque, the channel lined with reeds and trees hung with Spanish moss and vines. As they moved farther inland, the vegetation grew thicker, and the trees came together to form arches over the water. After a time, Sam called, “Idle the engine.”

The engine went to neutral, and the boat coasted a few yards with a minimum of sound, then stopped and drifted into a shaded copse. Somewhere in the distance behind them they could hear the growl of the black-and-gray boat’s engine. Sam and Remi exchanged a nod, and then Remi sped up again. They went on for another twenty minutes, and Sam waved at her again. She slowed down to a crawl while Sam came aft and looked at the chart.

“Get ready to anchor.”

“Are you sure?”

“Something wrong with this spot?”

“It’s a sweltering, mosquito-infested swamp where the alligators and the rare and celebrated American crocodiles can barely fight off the water moccasins. And I just saw an egret fall out of his tree from heat exhaustion.”

“Perfect,” Sam said. “Let’s get our wet suits on. They’ll protect us from the mosquitoes. Wear your booties, because we’ll be walking. And we might as well bring flippers too, in case we need speed.” Sam studied the chart, then put a big red X in a location about a half mile from their position.

“Isn’t that a little heavy-handed?”

“They will have worked so hard to see it that they’ll need to believe it.”

When they were ready, Sam used the blunt end of the gaff to pole them to shore and used the hook end to hold the boat while they got out and took a few steps into the mud. Sam pushed the boat so it could drift out into the middle of the channel.

“Now what?” she asked.

“Now we go on a great big hike.”
