"We'll put it aside for now," he said. "At least for the next few days. Then we'll revisit it, unless of course Svedberg was asking some extraordinary questions."

It was 9.15 a.m. Wallander got a cup of coffee and went into his office. He got out a pad of paper and wrote a single word at the top of the first page: Svedberg. Underneath it he drew a cross that he immediately scratched out. He didn't get any further. He had been meaning to write down all the thoughts that had come to him during the night. But he put down the pen and walked to the window. The August morning was sunny and warm. The thought that there was something not quite right about this case returned. Nyberg felt there was something arranged about the murder scene. If so, then why, and by whom?

He looked for Sture Björklund's number in the phone book and dialled it. The phone rang several times.

"Please accept my condolences," Wallander said, when the man answered.

Sture Björklund's voice sounded strained and distant.

"Likewise. You probably knew my cousin better than I did. Ylva called me at 6 a.m. this morning to tell me what had happened."

"Unfortunately this will make headlines in the papers," Wallander said.

"I know. As it happens it's the second murder case in our family."

"Really?"

"Yes, in 1847, or more precisely on 12 April 1847, a man who was Karl Evert's great-great-great-great-uncle was killed with an axe somewhere on the outskirts of Eslöv. The murderer was a soldier by the name of Brun, who had been given a dishonourable discharge from the army for a number of reasons. The murder was simply a matter of money. Our ancestor was a cattle man and fairly wealthy."

"What happened?" Wallander asked, trying to hide his impatience.

"The police, which I guess consisted of a sheriff and his assistant, made heroic efforts and arrested Brun on his way to Denmark a few days later. He was sentenced to death and executed. When Oscar I became king he took on the business of processing death sentences blocked by his predecessor, Charles XV. As many as 14 prisoners were executed as soon as he came to power. Brun was beheaded, somewhere in the vicinity of Malmö."

"What a strange story."

"I did some research into our ancestry a couple of years ago. Of course the case of Brun and the murder in Eslöv was already known."

"If it's all right with you, I'd like to come out to see you as soon as possible."

Sture Björklund immediately put up his guard.

"What about?"

"We're trying to clarify our picture of Karl Evert." It felt unnatural to use his first name.

"I didn't know him very well, though, and I have to go to Copenhagen this afternoon."

"This is urgent and it won't take much time."

The man was quiet at the other end of the line. Wallander waited.

"What time?"

"Around 2 p.m.?"

"I'll call Copenhagen and let them know I won't be in today."

Sture Björklund gave Wallander directions. His house didn't seem hard to find.

After the phone conversation, Wallander spent a half hour writing out a summary of the case. He was still searching for the thought he had had when he first saw Svedberg lying on the floor – the thought that something wasn't quite right, the same idea that had also struck Nyberg. Wallander realised that it could simply be a reaction to the unbearable and incomprehensible experience of seeing a colleague dead. But he still tried to explore what might have caused it.

A little after 10 a.m. he went to get another cup of coffee. A number of people were gathered in the canteen. There was a general atmosphere of shock and dismay. Wallander lingered for a while, talking to some traffic officers. Then he walked back to his office and called Nyberg on his mobile phone.

"Where are you?" Wallander asked.

"Where do you think?" he replied sourly. "I'm still in Svedberg's flat."

"You haven't seen a telescope, by any chance?"

"No."

"Anything else?"

"We have a number of prints on the shotgun. We'll be able to get complete copies of at least two or three of them."

"Then we'll hope he's already in the database. Is that it?"

"Yes."

"I'm on my way to question Svedberg's other cousin, who lives outside Hedeskoga. After that I'll be back to do a more thorough search of the flat."

"We'll be done by then. I'm also planning to attend the press conference."

Wallander couldn't remember Nyberg ever coming to a meeting that involved the press before. Maybe it was Nyberg's way of expressing how upset he was. Wallander was suddenly moved.

"Have you found any keys?" he asked after a moment.

"There are some car keys and a key to the basement storage area."

"Nothing in the attic?"

"There don't seem to be storage areas in the attic, only in the basement. You'll get the keys from me at the press conference."

Wallander hung up and went to Martinsson's office.

"Where's Svedberg's car?" he asked. "The Audi."

Martinsson didn't know. They asked Hansson, who didn't know either. Höglund wasn't in her office.

Martinsson looked at his watch.

"It's got to be in a car park close to the flat," he said. "I think I have time to check before 11 a.m."

Wallander went back to his office. He saw that people had started to send flowers. Ebba looked like she had been crying, but Wallander didn't say anything to her. He hurried past her as fast as he could.

The press conference started on time. Afterwards Wallander remembered thinking that Lisa Holgersson conducted the proceedings with dignity. He told her that no one could have done a better job. She was wearing her uniform and standing in front of a table with two bouquets of roses. Her speech was clear and to the point. She told the press the known facts, and her voice did not fail her this time. A respected colleague, Karl Evert Svedberg, had been found murdered in his flat. The exact time of death and the motive were not yet known, but there were indications that Svedberg was attacked by an armed burglar. The police did not have any leads. She concluded by describing Svedberg's career and his character. Wallander thought her description of Svedberg was very good, not exaggerated in any way. Wallander answered the few questions that were asked. Nyberg described the murder weapon as a Lambert Baron shotgun.

It was all over in half an hour. Afterwards, Holgersson was interviewed by the Sydnytt newspaper, while Wallander spoke to some reporters from the evening papers. It was only when they asked him to pose outside the block of flats on Lilla Norregatan that he let his impatience show.

At midday Holgersson asked the members of the investigative team to a simple lunch at her home. Wallander and Holgersson spoke about some of their memories of Svedberg. Wallander was the only one who had heard Svedberg explain why he had decided to become a police officer.

"He was afraid of the dark," Wallander said. "That's what he said. The fear had been with him since his earliest childhood, and he had never been able to understand it or overcome it. He became a police officer because he thought it would be a way to fight this fear, but it never left him."

A little before 1.30 p.m. they returned to the station. Wallander drove back with Martinsson.

"She handled that very well," Martinsson said.

"Lisa's good at her job," Wallander answered. "But you knew that already, didn't you?"

Martinsson didn't answer.

Wallander suddenly remembered something. "Did you find the Audi?"

"There's a private car park at the back of the building. It was there. I looked it over."

"Did you see a telescope in the boot?"

"There was only a spare tyre and a pair of boots. And a can of insecticide in the glove compartment."

"August is the month for bees," Wallander said glumly.
