backward and got hold of Adam before Adam saw the danger. They struggled for half a minute, Dooley managing to duck him until I went deep, grabbed Dooley’s leg, and dragged his head under. He fought hard, but I held him down until I heard him screaming. When I surfaced, I saw that Adam had bloodied Trey’s nose in a skirmish I’d missed. As soon as Adam saw that I was okay, we started kicking toward Louisiana, half swimming, half floating, staying high in the water like cottonmouth moccasins.
That worked well for fifteen minutes. Then we got separated. I’m still not sure how it happened. Maybe one of us got into an eddy, a boil, a whirlpool, something—but we lost sight of each other, and in the fog voices proved hard to track. The treachery of the Mississippi lies in its currents, which flow at different speeds and depths. This process creates dangerous surface effects. I’d thought I could handle them, but I was growing less sure as time passed. For the first ten minutes of the swim, I’d heard the Mathesons yelling and cursing, hooting insults. But for the last five minutes I’d heard nothing. Even stoned, they must have figured out that wasting energy in the river would kill them.
Tiring more quickly than I’d expected to, I started to worry about Adam. Certain he was behind me, I swam back and started a zigzag search, calling his name every ten seconds. The effort cost me two minutes, but I felt better after I collided with him in the fog. Then I saw that he looked pale, and he was panting in a way I’d never heard before. When I asked if he was okay, Adam told me somebody had been pulling at his legs, dragging him under. I was pretty sure the Mathesons were ahead of us, not behind, so I had no idea what might have been bothering him. An alligator gar? A big catfish? Both were unlikely.
I managed to stay close to him for another five minutes, but then we got separated again. Adam called out that he was okay and I should keep going. I did, but much more slowly than I could have, and I did a voice check every twenty seconds or so. I risked going a little ahead because I wanted to sight the opposite shore as soon as possible, to correct our course if we weren’t moving aggressively enough across the current. The sun had cleared the horizon by then, but with the fog it didn’t help much. As I swam, I realized my teeth were chattering. I wondered how long I had been shivering. I also sensed a vibration in the water, a subsonic rumble that felt more like my body was generating it than some external source. When Adam cried out for help, I turned back instantly, but again it took some time to find him in the fog.
As soon as I did, I saw he was in trouble. He was doubled over in the water, struggling even to stay afloat.
“My legs cramped up,” he choked out. His face was gray, his eyes glassy, and his teeth were chattering. “My calves. I can’t get them loose!”
I knew what had happened. The past thirty-six hours—which included the state track meet, serious alcohol intake, the foot race on the levee, and the long tower climb—had depleted Adam’s potassium to the point that his skeletal muscles wouldn’t function properly. I tried diving to massage the cramps out, but it did little good. I needed to get him to shore.
“Trey!” I shouted. “Dooley! Adam’s in trouble! We need help!”
“They won’t help,” Adam said. “They’ll be lucky to make it themselves.”
“Listen, I need you to go limp. Try to relax. I’m going to put you in a buddy tow and swim you to shore.”
“You can’t tow me that far. Not in this river.”
“Bullshit. You know I can. Do what I say.”
“I can make it,” Adam insisted, trying to pull himself through the water.
“Not cramped like that, you can’t. Lie back! I’m going to tow you to Louisiana.”
“Just gotta wait for my legs to . . .”
He fell silent. Adam had heard what I had. The rumble I’d barely perceived before seemed suddenly upon us, around us, beneath us. Somewhere in that fog, not far away, a string of barges was being pushed by a tugboat. Pushed toward us. Panic bloomed in my chest, and Adam saw it in my eyes.
