No wonder that Sloth could add a knighthood and international orders to the list.

‘I only have fifteen minutes,’ he began his handshake with. Sloth sat down, crossed his legs, tossed his autumn coat casually aside and lifted the creases of his trousers a tad so his knees wouldn’t stretch the fabric. It was quite easy to picture him in a boarding-school environment. Much harder to envision him in the sandbox with his children.

‘Kåre Bruno was my best friend,’ he said, ‘and I know he would never have entertained the thought of going to an outdoor public pool, so it’s very odd that he was found at Bellahøj. A place such as that was far too close to all kinds of people, you understand.’ He actually meant it. ‘Besides, I’d never seen him dive before, and most certainly not from a ten-metre board.’

‘You don’t think it was an accident?’

‘How could it be an accident? Kåre was a smart chap. He wouldn’t just dawdle about up there when everyone knows falling off would be fatal.’

‘And it couldn’t have been suicide?’

‘Suicide! Why? We had just graduated. His father had given him a Buick Regal Limited as a graduation gift. A coupé model, you know?’

Carl nodded hesitantly because he didn’t bloody know. He knew that Buick was a type of car, and that would have to do.

‘He was set to go to the US to study law. Harvard, right? Why would he do something so idiotic? That doesn’t make any sense whatsoever.’

‘Was he lovesick?’ Carl asked cautiously.

‘Ha! He could have had whoever he wanted.’

‘You remember Kimmie Lassen?’

He grimaced. The memory of her didn’t please him.

‘Was he upset that she’d dumped him?’

‘Upset? He was furious. He didn’t like being dropped. Who does?’ He smiled, teeth gleaming whitely, and swept the hair from his forehead. Hair that was tinted and newly cut, of course.

‘And what was he going to do about it?’

Mannfred Sloth shrugged, brushing a few specks of dust from his coat. ‘I’m here today because I think we both believe he was murdered. That he was pushed over the edge. Otherwise, why would you bother contacting me twenty years later? Am I correct?’

‘We’re not absolutely certain, but naturally there’s a reason we’re working on the case again. Who do you think might have pushed him?’

‘I have no idea. Kimmie had some sick friends in her class. They ran around her like satellites. She had them in the palm of her hand. Lovely breasts, you know? Tits rule, am I right?’ He gave a short, dry laugh. It didn’t suit him.

‘Do you know if he tried to win her back?’

‘She already had something going with one of the teachers. One from the suburbs without the common sense to know pupils were off limits.’

‘Do you remember his name?’

He shook his head. ‘He hadn’t been there terribly long. He taught a few Danish classes, I think. He wasn’t the kind of person you noticed if you didn’t have him as a teacher. His …’ He paused and raised a finger in the air, his face radiating remembrance and concentration. ‘Yes. Now I’ve got it. His name was Klavs. With a “v”, for God’s sake!’ He snorted. The name alone was pathetic.

‘Klavs, you say! Klavs Jeppesen?’

He raised his head. ‘Yes, Jeppesen. I believe that was it.’ He nodded.

Pinch my arm, I must be dreaming, Carl thought. He was going to meet Jeppesen that very evening.

‘Just put the coffee there, Assad. Thank you.’

‘Well, I must say,’ Carl’s guest said with a crooked smile. ‘You have humble conditions down here, but at least the help is well trained.’ He laughed the same dry laugh and Carl could imagine only too well how he had treated the natives in Mozambique.

Sloth tasted the coffee and with the first gulp clearly had had enough.

‘OK,’ he said. ‘I know he was still keen on the girl. There were many who were. So when she was expelled he wanted her all to himself, naturally. She was living in Næstved then.’

‘I don’t understand how he came to die in Bellahøj.’

‘When we were done with our exams, he moved in with his grandparents. He had stayed with them before. They lived in Emdrup. Very sweet, fine people they were. I spent a lot of time there back then.’

‘His parents weren’t in Denmark?’

He shrugged. No doubt Mannfred Sloth’s children also went to boarding school so he could devote himself to his own affairs. Fuck him.

‘Did anyone in Kimmie’s circle live near the swimming centre?’

He looked right through Carl. Now, finally, he recognized the gravity that the room exuded. The files with the old cases. The photographs on the noticeboard. The list of assault victims, with his friend Kåre Bruno’s name at the top.

Shit, Carl thought, when he turned round and realized what Sloth was staring at.

‘What’s that?’ Sloth asked, with a menacing seriousness, his finger pointing at the list.

‘Oh,’ Carl said. ‘The cases aren’t connected. We’re in the process of categorizing our files in chronological order.’

Idiotic explanation, thought Carl. Why in the world would they write on the board what could just as easily be in files on the shelf?

But Mannfred Sloth didn’t ask any questions. He wasn’t the type who did that kind of slave labour, so how would he know about such basic procedures?

‘You must have your hands full,’ he said.

Carl spread his arms. ‘That’s why it’s so important that you answer my questions as precisely as you can.’

‘What was it you asked?’

‘I simply asked if anyone in the gang lived near Bellahøj.’

He nodded without hesitation. ‘Yes, Kristian Wolf did. His parents owned quite an impressive, functionalist house down by the lake, which he moved into when he threw his father out of the firm. And actually I think his wife still lives there with her new husband.’

He didn’t get any more out of him. But what he got wasn’t so bad.

‘Rose,’ he called, when the hard sound of Mannfred Sloth’s Lloyd shoes had faded. ‘What do you know about Kristian Wolf’s death?’

‘Hello, Carl?’ She tapped her head with her notepad. ‘Do you have Alzheimer’s or what? You gave me five tasks, and that one was number four according to your own prioritization. So what do you suppose I know about it?’

He’d forgotten. ‘So when can you tell me something? Can’t you switch the order around?’

She put her hands on her hips like an Italian mama about to yell at her scoundrel of a husband lounging on the sofa. Then she suddenly smiled. ‘Oh, to hell with it. I can’t keep a straight face anyway.’ She licked her finger and riffled through her notepad. ‘Do you think you get to decide everything? Of course I did that one first. It was obviously the easiest.’

When he died, Kristian Wolf was only just under thirty years old, but filthy rich. His father had founded the shipping company, but Kristian outmanoeuvred and ruined him. People said his father had it coming; he’d raised a son without feelings and when push came to shove, that’s what he got in return.

He was a bachelor rolling in money, and for that reason his June marriage to a countess – the third daughter of Baron Saxenholdt, Maria Saxenholdt – caused a sensation. Their wedded bliss lasted barely three months, the press wrote, before Kristian Wolf was killed in a shooting accident on 15 September 1996.

It all seemed so pointless, and maybe that was the reason the newspaper coverage was endless. There were far more articles about his death than about the new bus terminal at Copenhagen’s City Hall, and nearly as many as about Bjarne Riis winning the Tour de France a few weeks earlier.

He had gone out alone very early one morning at his weekend estate on the island of Lolland. He was supposed to meet the rest of the hunting party half an hour later, but more than two hours passed before they found him with an ugly gunshot wound in one thigh, his body completely drained of blood. It had to have been a fairly quick demise, the autopsy report concluded.
