Blomkvist directed him to Henrik Vanger’s newly shovelled courtyard, where he lifted his suitcases on to the cobblestones and watched the taxi head back towards Hedestad. He suddenly felt lonely and uncertain.

He heard the door open behind him. Vanger was wrapped up in a heavy fur coat, thick boots, and a cap with earflaps. Blomkvist was in jeans and a thin leather jacket.

“If you’re going to live up here, you need to learn to dress more warmly for this time of year.” They shook hands. “Are you sure you don’t want to stay in the main house? No? Then I think we’d better start getting you settled into your new lodgings.”

One of the conditions in his negotiations with Vanger and Dirch Frode had been that he have living quarters where he could do his own housekeeping and come and go as he pleased. Vanger led Blomkvist back along the road towards the bridge and then turned to open the gate to another newly shovelled courtyard in front of a small timbered house close to the end of the bridge. The house was not locked. They stepped into a modest hallway where Blomkvist, with a sigh of relief, put down his suitcases.

“This is what we call our guest house. It’s where we usually put people up who are going to stay for a longer period of time. This was where you and your parents lived in 1963. It’s one of the oldest buildings in the village, but it’s been modernised. I asked Nilsson, my caretaker, to light the fire this morning.”

The house consisted of a large kitchen and two smaller rooms, totalling about 500 square feet. The kitchen took up half the space and was quite modern, with an electric stove and a small refrigerator. Against the wall facing the front door stood an old cast-iron stove in which a fire had indeed been lit earlier in the day.

“You don’t need to use the woodstove unless it gets bitterly cold. The firewood bin is there in the hallway, and you’ll find a woodshed at the back. The house has been unlived-in this autumn. The electric heaters are usually sufficient. Just make sure you don’t hang any clothes on them, or it may start a fire.”

Blomkvist looked around. Windows faced three different directions, and from the kitchen table he had a view of the bridge, about a hundred feet away. The furnishings in the kitchen included three big cupboards, some kitchen chairs, an old bench, and a shelf for newspapers. On top was an issue of See from 1967. In one corner was a smaller table that could be used as a desk.

Two narrow doors led to smaller rooms. The one on the right, closest to the outside wall, was hardly more than a cubbyhole with a desk, a chair, and some shelves along the wall. The other room, between the hallway and the little office, was a very small bedroom with a narrow double bed, a bedside table, and a wardrobe. On the walls hung landscape paintings. The furniture and wallpaper in the house were all old and faded, but the place smelled nice and clean. Someone had worked over the floor with a dose of soap. The bedroom had another door to the hallway, where a storeroom had been converted into a bathroom with a shower.

“You may have a problem with the water,” Vanger said. “We checked it this morning, but the pipes aren’t buried very deep, and if this cold hangs on for long they may freeze. There’s a bucket in the hallway so come up and get water from us if you need to.”

“I’ll need a telephone,” Blomkvist said.

“I’ve already ordered one. They’ll be here to install it the day after tomorrow. So, what do you think? If you change your mind, you would be welcome in the main house at any time.”

“This will be just fine,” Blomkvist said.

“Excellent. We have another hour or so of daylight left. Shall we take a walk so you can familiarise yourself with the village? Might I suggest that you put on some heavy socks and a pair of boots? You’ll find them by the front door.” Blomkvist did as he suggested and decided that the very next day he would go shopping for long underwear and a pair of good winter shoes.

The old man started the tour by explaining that Blomkvist’s neighbour across the road was Gunnar Nilsson, the assistant whom Vanger insisted on calling “the caretaker.” But Blomkvist soon realised that he was more of a superintendent for all the buildings on Hedeby Island, and he also had responsibility for several buildings in Hedestad.

“His father was Magnus Nilsson, who was my caretaker in the sixties, one of the men who helped out at the accident on the bridge. Magnus is retired and lives in Hedestad. Gunnar lives here with his wife, whose name is Helena. Their children have moved out.”

Vanger paused for a moment to shape what he would say next, which was: “Mikael, the official explanation for your presence here is that you’re going to help me write my autobiography. That will give you an excuse for poking around in all the dark corners and asking questions. The real assignment is strictly between you and me and Dirch Frode.”

“I understand. And I’ll repeat what I said before: I don’t think I’m going to be able to solve the mystery.”

“All I ask is that you do your best. But we must be careful what we say in front of anyone else. Gunnar is fifty-six, which means that he was nineteen when Harriet disappeared. There’s one question that I never got answered-Harriet and Gunnar were good friends, and I think some sort of childish romance went on between them. He was pretty interested in her, at any rate. But on the day she disappeared, he was in Hedestad; he was one of those stranded on the mainland. Because of their relationship, he came under close scrutiny. It was quite unpleasant for him. He was with some friends all day, and he didn’t get back here until evening. The police checked his alibi and it was airtight.”

“I assume that you have a list of everyone who was on the island and what everybody was doing that day.”

“That’s correct. Shall we go on?”

They stopped at the crossroads on the hill, and Vanger pointed down towards the old fishing harbour, now used for small boats.

“All the land on Hedeby Island is owned by the Vanger family-or by me, to be more precise. The one exception is the farmland at Östergården and a few houses here in the village. The cabins down there at the fishing harbour are privately owned, but they’re summer cottages and are mostly vacant during the winter. Except for that house farthest away-you can see smoke coming from the chimney.”

Blomkvist saw the smoke rising. He was frozen to the bone.

“It’s a miserably draughty hovel that functions as living quarters year-round. That’s where Eugen Norman lives. He’s in his late seventies and is a painter of sorts. I think his work is kitsch, but he’s rather well known as a landscape painter. You might call him the obligatory eccentric in the village.”

Vanger guided Blomkvist out towards the point, identifying one house after the other. The village consisted of six buildings on the west side of the road and four on the east. The first house, closest to Blomkvist’s guest house and the Vanger estate, belonged to Henrik Vanger’s brother Harald. It was a rectangular, two-storey stone building which at first glance seemed unoccupied. The curtains were drawn and the path to the front door had not been cleared; it was covered with a foot and a half of snow. On second glance, they could see the footprints of someone who had trudged through the snow from the road up to the door.

“Harald is a recluse. He and I have never seen eye to eye. Apart from our disagreements over the firm-he’s a shareholder-we’ve barely spoken to each other in nearly 60 years. He’s ninety-two now, and the only one of my four brothers still alive. I’ll tell you the details later, but he trained to be a doctor and spent most of his professional life in Uppsala. He moved back to Hedeby when he turned seventy.”

“You don’t care much for each other, and yet you’re neighbours.”
