Elinborg started by talking about herself, who she was and what she did in the police, and how she wanted to catch the people who did this to him. Erlendur stood at a distance, watching. The boy stared at Elinborg. She knew that she was only supposed to talk to him in the presence of one of his parents. Elinborg and Erlendur had arranged to meet the father at the hospital but half an hour had gone by and he hadn’t turned up.

“Who was it?” Elinborg said at last when she thought it was time to get to the point.

The boy looked at her but said nothing.

“Who did this to you? It’s all right to tell me. They won’t attack you again. I promise.”

The boy cast a glance at Erlendur.

“Was it the boys from your school?” Elinborg asked. “The big boys. We’ve found out that two of the suspects are known troublemakers. They’ve beaten up boys like you before, but not so violently. They say they didn’t do anything to you but we know they were at the school at the time you were attacked.”

Silently, the boy watched Elinborg tell her story. She had gone to the school and talked to the headmaster and teachers, then gone to the homes of the two boys to find out about their backgrounds, where she heard them deny doing anything to him. The father of one of them was in prison.

The paediatrician entered the room. He told them that the boy needed to rest and they would have to come back later. Elinborg nodded and they took their leave.

Erlendur also accompanied Elinborg to meet the boys father at his house later the same day. The father’s explanation for not being able to go to the hospital was that he had to take part in an important conference call with his colleagues in Germany and the US. “It came up unexpectedly,” he told them. When he finally managed to get away they had left the hospital.

While he was saying this the winter sun started to shine in through the lounge window, illuminating the marble floor and the carpet on the stairs. Elinborg was standing and listening when she noticed the stain on the stair carpet and another on the stair above it.

Little stains, almost invisible had it not been for the winter sun pouring in.

Stains that had been almost cleansed from the carpet and on first impression seemed to be part of the texture of the material.

Stains that turned out to be little footprints.

“Are you there?” Elinborg said over the telephone. “Erlendur? Are you there?”

Erlendur came back to his senses.

“Let me know when he leaves,” he said, and they rang off.

The head waiter at the hotel was aged about forty, thin as a rake, wearing a black suit and shiny black patent leather shoes. He was in an alcove off the dining room, checking the reservations for that evening. When Erlendur introduced himself and asked whether he might disturb him for a moment, the head waiter looked up from his dogeared reservations book to reveal a thin black moustache, dark stubble that he obviously needed to shave twice a day, a brownish complexion and brown eyes.

“I didn’t know Gulli in the slightest,” said the man, whose name was Rosant. “Terrible what happened to him. Are you getting anywhere?”

“Nowhere at all,” Erlendur said curtly. His mind was on the biotechnician and the father who beat up his son, and he was thinking about his daughter, Eva Lind, who said she could not hold out any longer. Although he knew what that meant, he hoped he was wrong. “Busy around Christmas,” Erlendur said, “aren’t you?”

“We’re trying to make the most of the season. Trying to fill the dining room three times for each buffet, which can be very difficult because some people think that when they’ve paid it’s like a take-away. The murder in the basement doesn’t help.”

“No,” Erlendur said without any interest. “So you haven’t been working here long if you didn’t know Gudlaugur.”

“Two years. But I didn’t have much contact with him.”

“Who do you think knew him best among the hotel staff?”

“I just don’t know,” the head waiter said, stroking his black moustache with his index finger. “I don’t know anything about the man. The cleaners, maybe. When do we hear about the saliva tests?”

“Hear what?”

“Who was with him. Isn’t it a DNA test?”

“Yes,” Erlendur said.

“Do you have to send it abroad?”

Erlendur nodded.

“Do you know whether anyone visited him in the basement? People from outside the hotel?”

“There’s so much traffic here. Hotels are like that. People are like ants, in and out, up and down, never a moment’s peace. At catering college we were told that a hotel isn’t a building or rooms or service, but people. A hotel’s just people. Nothing else. Our job is to make them feel good. Feel at home. Hotels are like that.”

“I’ll try to remember that,” Erlendur said, and thanked him.

He checked whether Henry Wapshott had returned to the hotel, but he was still out. However, the head of reception was back at work and he greeted Erlendur. Yet another coach had pulled up outside, full of tourists, who swarmed into the lobby, and he gave Erlendur an awkward smile and shrugged, as if it was not his fault they couldn’t talk and their business would have to wait.

Gudlaugur Egilsson joined the hotel in 1982, at the age of twenty-eight. He had held various jobs before, most recently as a nightwatchman at the Ministry for Foreign Affairs. When it was decided to employ a full-time doorman at the hotel, he got the job. Tourism was booming then. The hotel had expanded and was taking on more staff. The previous hotel manager couldn’t remember exactly why Gudlaugur was selected, but he didn’t recall there having been many applicants.

He made a good impression on the hotel manager. With his gentlemanly manner, polite and service-minded, he turned out to be a fine employee. He had no family, neither a wife nor children, which caused the manager some concern, because family men often proved to be more loyal. In other respects Gudlaugur did not say much about himself and his past.

Shortly after joining the staff he went to see the manager and asked if there was a room at the hotel for him to use while he was finding himself a new place to live. After losing his room at short notice he was on the street. He pointed out that there was a little room at the far end of the basement corridor where he could stay until he found a place of his own. They went down to inspect the room. All kinds of rubbish had been stored away in it and Gudlaugur said he knew of a place where it could all be kept, although most of it deserved to be thrown out anyway.

So in the end Gudlaugur, then a doorman and later a Santa Claus, moved into the little room where he would stay for the rest of his life. The hotel manager thought he would be there for a couple of weeks at the very most. Gudlaugur spoke in those terms and the room was not the sort of place anyone would want to live permanently. But Gudlaugur demurred about finding himself proper living quarters and soon it was taken for granted that he lived at the hotel, especially after his job developed more towards caretaking than being a straightforward doorman. As time wore on it was seen as a convenient arrangement to have him on call round the clock, lest something went wrong and a handyman was needed.

“Shortly after Gudlaugur moved into the room, the old manager left,” said Sigurdur Oli, who was up in Erlendur’s room describing his meeting. It was well into the afternoon and beginning to get dark.

“Do you know why?” Erlendur asked. He was stretched out on the bed, staring up at the ceiling. “The hotel had just been expanded, loads of new staff recruited and he leaves shortly afterwards. Don’t you find that strange?”

“I didn’t go into that. I’ll find out what he says if you think it’s of the slightest importance. He didn’t know Gudlaugur had played Santa Claus. That started after his day and he was really shocked to hear that he was found murdered in the basement.”
