Claude comes back with the beer and I say "Thank you" and glance up at him and his face dissolves and re-forms, he was about eight the last time I was here; he used to peddle worms in rusted tin cans to the fishermen down by the government dock. He's uneasy now, he can tell I recognize him.

"I'd like to go down the lake for a couple of days," I say, to David because it's his car. "I'd like to look around, if that's okay."

"Great," says David, "I'm gonna get me one of them smart fish." He brought along a borrowed fishing rod, though I warned him he might not have a chance to use it: if my father had turned up after all we would have gone away without letting him find out we were here. If he's safe I don't want to see him. There's no point, they never forgave me, they didn't understand the divorce; I don't think they even understood the marriage, which wasn't surprising since I didn't understand it myself. What upset them was the way I did it, so suddenly, and then running off and leaving my husband and child, my attractive full-colour magazine illustrations, suitable for framing. Leaving my child, that was the unpardonable sin; it was no use trying to explain to them why it wasn't really mine. But I admit I was stupid, stupidity is the same as evil if you judge by the results, and I didn't have any excuses, I was never good at them. My brother was, he used to make them up in advance of the transgressions; that's the logical way.

"Oh god," Anna says, "David thinks he's a great white hunter." She's teasing him, she does that a lot; but he doesn't hear, he's getting up, Claude is hustling him off to make him out a licence, it seems Claude is in charge of the licences. When David comes back I want to ask how much he paid, but he's too pleased, I don't want to spoil it. Claude is pleased also.

We find out from Claude we can hire Evans, who owns the Blue Moon Cabins, to run us down the lake. Paul would take us for nothing, he offered, but I wouldn't feel right about it; also I'm sure he would misinterpret Joe's amorphous beard and David's moustache and Three Musketeers hair. They're just a style now, like crew cuts, but Paul might feel they are dangerous, they mean riots.

David eases the car down the turnoff, two ruts and a rock hump in the centre that scrapes the car's belly. We brake in front of the cabin marked OFFICE; Evans is there, a bulky laconic American in checked shirt and peaked cap and a thick knitted jacket with an eagle on the back. He knows where my father's place is, all the older guides know every house on the lake. He moves his cigarette butt to the corner of his mouth and says he'll take us there, ten miles, for five dollars; for another five he'll pick us up two days from now, in the morning. That will give us the rest of the day to drive back to the city. He's heard of the disappearance, of course, but he doesn't mention it.

"A groovy old guy, eh?" David says when we're outside. He's enjoying himself, he thinks this is reality: a marginal economy and grizzled elderly men, it's straight out of Depression photo essays. He spent four years in New York and became political, he was studying something; it was during the sixties, I'm not sure when. My friends' pasts are vague to me and to each other also, any one of us could have amnesia for years and the others wouldn't notice.

When David has backed the car down to the Blue Moon dock we unload our stuff, the packsacks of clothes, the camera equipment, the samsonite case with my career in it, the half dozen Red Caps they got at the motel and the paper bag of food. We scramble into the boat, a battered wood-hulled launch; Evans starts the motor and we churn out slowly. Summer cottages beginning to sprout here, they spread like measles, it must be the paved road.

David sits in front beside Evans. "Gettin' many fish?" he asks, folksy, chummy, crafty. "Here and there, here and there," Evans says, giving no free handouts; then he switches the motor into high gear and I can't hear any more.

I wait until we're into the middle of the lake. At the right moment I look over my shoulder as I always did and there is the village, suddenly distanced and clear, the houses receding and grouping, the white church startling against the dark of the trees. The feeling I expected before but failed to have comes now, homesickness, for a place where I never lived, I'm far enough away; then the village shrinks, optical illusion, and we're around a point of land, it's behind us.

The three of us are together on the back seat, Anna beside me. "This is good," she says to me, voice shrilling over the engine roar, "it's good for us to get away from the city"; but when I turn to answer there are tears on her cheek and I wonder why, she's always so cheerful. Then I realize they aren't tears, it's started to drizzle. The raincoats are in our packsacks; I didn't notice it had clouded over. We won't be very wet though, with this boat it will only take half an hour; before, with the heavier boats and primitive motors, it took two to three hours depending on the wind. In the city people would say to my mother, "Aren't you afraid? What if something happened?" They were thinking of the time it would take to get to a doctor.

I'm cold, I huddle my shoulders up; drops ping onto my skin. The shoreline unrolls and folds together again as we go past; forty miles from here there's another village, in between there's nothing but a tangled maze, low hills curving out of the water, bays branching in, peninsulas which turn into islands, islands, necks of land leading to other lakes. On a map or in an aerial photograph the water pattern radiates like a spider, but in a boat you can see only a small part of it, the part you're in.

The lake is tricky, the weather shifts, the wind swells up quickly; people drown every year, boats loaded topheavy or drunken fishermen running at high speed into deadheads, old pieces of tree waterlogged and partly decayed, floating under the surface, there are a lot of them left over from the logging and the time they raised the lake level. Because of the convolutions it's easy to lose the way if you haven't memorized the landmarks and I watch for them now, dome-shaped hill, point with dead pine, stubble of cut trunks poking up from a shallows, I don't trust Evans.

But he's taken the right turns so far, we're coming into my territory, two short bends and through a passage between granite shores and out into a wider bay. The peninsula is where I left it, pushing out from the island shore with the house not even showing through the trees, though I know where it is; camouflage was one of my father's policies.

Evans arches the boat around the point and slows for the dock. The dock slants, the ice takes something away from it every winter and the water warps and rots it; it's been repaired so much all the materials are different, but it's the same dock my brother fell off the time he drowned.

He used to be kept in a chicken-wire enclosure my father built for him, large cage or small playground, with trees, a swing, rocks, a sandpile. The fence was too high for him to climb over but there was a gate and one day he learned how to open it. My mother was alone in the house; she glanced out the window, checking, and he was no longer in the cage. It was a still day, no wind noise, and she heard something down by the water. She ran to the dock, he wasn't there, she went out to the end of it and looked down. My brother was under the water, face upturned, eyes open and unconscious, sinking gently; air was coming out of his mouth.

It was before I was born but I can remember it as clearly as if I saw it, and perhaps I did see it: I believe that an unborn baby has its eyes open and can look out through the walls of the mother's stomach, like a frog in a jar.
