Into my head the tugboat floated, the one that was on the lake before, logboom trailing it, men waving from the cabin, sunlight and blue sky, the perfect way. But it didn't last. One spring when we got to the village it was beached near the government dock, abandoned. I wanted to see what the little house was like, how they had lived; I was sure there would be a miniature table and chairs, beds that folded down out of the walls, flowered window curtains. We climbed up; the door was open but inside it was bare wood, not even painted; there was no furniture at all and the stove was gone. The only things we could find were two rusted razor blades on the windowsill and some pictures drawn on the walls in pencil.

I thought they were plants or fish, some of them were shaped like clams, but my brother laughed, which meant he knew something I didn't; I nagged at him until he explained. I was shocked, not by those parts of the body, we'd been told about those, but that they should be cut off like that from the bodies that ought to have gone with them, as though they could detach themselves and crawl around on their own like snails.

I'd forgotten about that; but of course they were magic drawings like the ones in caves. You draw on the wall what's important to you, what you're hunting. They had enough food, no need to draw tinned peas and Argentine corned beef, and that's what they wanted instead during those monotonous and not at all idyllic trips up and down the lake, nothing to do but play cards, they must have detested it, back and forth chained to the logs. All of them dead now or old, they probably hated each other.

The bass struck on both lines at once. They fought hard, the rods doubled over. David landed one but Joe let his escape into the labyrinth of sticks, where it wound the line around a branch and snapped it.

"Hey," David was saying, "kill it for me." The bass was fierce, it was flipping around the inside of the canoe. It spat water from its undershot jaw with a hissing sound; it was either terrified or enraged, I couldn't tell which.

"You do it," I said, handing him the knife. "I showed you how, remember?"

Thud of metal on fishbone, skull, neckless headbody, the fish is whole, I couldn't any more, I had no right to. We didn't need it, our proper food was tin cans. We were committing this act, violation, for sport or amusement or pleasure, recreation they call it, these were no longer the right reasons. That's an explanation but no excuse my father used to say, a favourite maxim.

While they admired David's murder, cadaver, I took the bottle with the frogs in it out of the tackle box and unscrewed the top; they slipped into the water, green with black leopard spots and gold eyes, rescued. Highschool, each desk with a tray on it and a frog, exhaling ether, spread and pinned flat as a doily and slit open, the organs explored and clipped out, the detached heart still gulping slowly like an adam's apple, no martyr's letters on it, the intestines messy string. Pickled cat pumped full of plastic, red for the arteries, blue for the veins, at the hospital, the undertaker's. Find the brain of the worm, donate your body to science. Anything we could do to the animals we could do to each other: we practised on them first.

Joe flipped his broken line back to me and I rummaged among the lures and found another leader, a lead sinker, another hook: accessory, accomplice.

The Americans had rounded the point, two of them in a silver canoe; they were barging towards us. I assessed them, their disguises: they weren't the bloated middle-aged kind, those would stick to powerboats and guides; they were younger, trimmer, with the candid, tanned astronaut finish valued by the magazines. When they were even with us their mouths curved open, showing duplicate sets of teeth, white and even as false ones.

"Gettin' any?" the front man said with a midwestern accent; traditional greeting.

"Lots," David said, smiling back. I was expecting him to say something to them, insult them, but he didn't. They were quite large.

"Us too," the front one said. "We been in here three-four days, they been biting the whole time, caught our limit every day." They had a starry flag like all of them, a miniature decal sticker on the canoe bow. To show us we were in occupied territory.

"Well, see ya," the back one said. Their canoe moved past us towards the next beaver house.

Raygun fishing rods, faces impermeable as space-suit helmets, sniper eyes, they did it; guilt glittered on them like tinfoil. My brain recited the stories I'd been told about them: the ones who stuffed the pontoons of their seaplane with illegal fish, the ones who had a false bottom to their car, two hundred lake trout on dry ice, the game warden caught them by accident. "This is a lousy country," they said when he wouldn't take the bribe, "we ain't never coming back here." They got drunk and chased loons in their powerboats for fun, backtracking on the loon as it dived, not giving it a chance to fly, until it drowned or got chopped up in the propeller blades. Senseless killing, it was a game; after the war they'd been bored.

The sunset was fading, at the other side of the sky the black was coming up. We took the fish back, four of them by now, and I cut a Y-shaped sapling stringer to go through the gills.

"Poo," Anna said to us, "you smell like a fish market."

David said "Wish we had some beer. Maybe we could get some off the Yanks, they're the type."

I went down to the lake with the bar of soap to wash the fish blood off my hands. Anna followed me.

"God," she said, "what'm I going to do? I forgot my makeup, he'll kill me."

I studied her: in the twilight her face was grey. "Maybe he won't notice," I said.

"He'll notice, don't you worry. Not now maybe, it hasn't all rubbed off, but in the morning. He wants me to look like a young chick all the time, if I don't he gets mad."

"You could let your face get really dirty," I said.

She didn't answer that. She sat down on the rock and rested her forehead on her knees. "He'll get me for it," she said fatalistically. "He's got this little set of rules. If I break one of them I get punished, except he keeps changing them so I'm never sure. He's crazy, there's something missing in him, you know what I mean? He likes to make me cry because he can't do it himself."

"But that can't be serious," I said, "the makeup thing."

A sound came out of her throat, a cough or a laugh. "It's not just that; it's something for him to use. He watches me all the time, he waits for excuses. Then either he won't screw at all or he slams it in so hard it hurts. I guess it's awful of me to say that." Her eggwhite eyes turned towards me in the half-darkness. "But if you said any of this to him he'd just make funny cracks about it, he says I have a mind like a soap opera, he says I invent it. But I really don't, you know." She was appealing to me for judgment but she didn't trust me, she was afraid I would talk to him about it behind her back.

"Maybe you should leave," I said, offering my solution, "or get a divorce."

"Sometimes I think he wants me to, I can't tell any more. It used to be good, then I started to really love him and he can't stand that, he can't stand having me love him. Isn't that funny?" She had my mother's leather jacket over her shoulders, she'd brought it because she didn't have a heavy sweater. With Anna's head attached to it it was incongruous, diminished. I tried to think about my mother but she was blanked out; the only thing that remained was a story she once told about how, when she was little, she and her sister had made wings for themselves out of an old umbrella; they'd jumped off the barn roof, attempting to fly, and she broke both her ankles. She would laugh about it but the story seemed to me then chilly and sad, the failure unbearable.
