‘So we’ve got to tread cautiously,’ Rose grunted.

‘Correct. We’re being left in peace to work for now, and they mustn’t know this. Especially because we believe that interrogating Kimmie, given her situation, would be greatly to our advantage. Through her we might get some clarity about what the gang got up to back then.’

‘She won’t say anything, Carl,’ Assad interjected. ‘Not the way she looked at me at the central station.’

Carl thrust out his lower lip. ‘Yeah, yeah, we’ll see. Kimmie Lassen is probably a few sandwiches short of a picnic. How could she not be, living on the street when she has a palace in Ordrup? A miscarriage in mysterious circumstances, where she was apparently repeatedly subjected to violence – this has probably contributed to the situation.’ He considered fishing out a cigarette, but Rose’s coal-black-mascara glare was resting heavily on his hands. ‘We also know that one of the gang members, Kristian Wolf, died a few weeks after Kimmie Lassen disappeared, but we don’t know whether the two facts are connected. Today, however, I learned from his widow that Wolf had sadistic tendencies, and it was also suggested that he had a relationship with Kimmie Lassen.’ His fingers were now wrapped around the pack of cigarettes. So far so good.

‘But the most important lead in the case is that we now know one or more of the gang committed assaults in addition to the murders in Rørvig. Kimmie Lassen had hidden effects that positively indicate at least four deadly attacks, and two additional plastic pockets with effects give us cause to suspect more.

‘So now we’ll try to rope in Kimmie, follow the actions of the other suspects and finish off our other assignments. Do you have anything to add to the summary?’ Then he lit his cigarette.

‘You still have the teddy bear in your pocket, I see,’ Rose said, eyes on the cigarette.

‘Right. Anything else?’

They shook their heads.

‘Good. Fire away, Rose. What did you find out?’

She watched the spiral of smoke creeping towards her. In a moment she would begin fanning it away. ‘Not very much, and yet a fair amount.’

‘That sounds cryptic. Let’s hear it.’

‘Besides Klaes Thomasen, I’ve only been able to locate one policeman involved in the investigation. A Hans Bergstrøm, who was part of the Mobile Investigation Unit back then. Today he has another job, and anyway, he’s impossible to talk to.’ Now she fanned the smoke away.

‘There’s no one who is impossible to talk to,’ Assad interrupted. ‘He’s just angry at you because you called him a dumb shit.’ He smiled broadly when she protested. ‘Yes, Rose, I heard it.’

‘I put my hand over the phone. He didn’t hear it. It’s not my fault he didn’t want to talk. He’s made a fortune off his patents now, and I’ve also found out something else about him.’ She began blinking and fanning again.

‘And that is?’

‘He is also an old boarding-school pupil. We won’t get anything out of him.’

Carl closed his eyes and wrinkled his nose. To show solidarity was one thing, to be thick as thieves quite another. What a bloody nuisance.

‘It’s the same with the gang’s old classmates. None of them will talk to us.’

‘How many have you got in contact with? They must be scattered to the winds. And the girls might have new surnames.’

She fanned so demonstratively now that Assad inched away from her. It did look threatening. ‘Apart from those who live on the other side of the globe, and are getting their beauty sleep right now, I’ve contacted almost all of them. And I think that’s enough now. They refuse to say anything, if they say anything at all. There was only one person who hinted at what they were like.’

This time Carl blew the smoke away from her. ‘I see. What did that person say?’

‘All he said was that they were a wild bunch who bent the school’s rules. They smoked hash in the woods and in the parks near the school. But he still seemed to think they were decent enough people. Listen, Carl, can’t you put that nicotine bastard away while we’re holding a meeting?’

He’d managed ten drags. That would have to do.

‘If only we could speak directly with someone from the gang, Carl,’ Assad interjected. ‘But I suppose we can’t.’

‘If we contact any of them, I think the whole case will slip through our fingers.’ He snuffed his cigarette in his coffee cup, which clearly irritated Rose. ‘No, we’ll wait to talk to them. But what do you have for us, Assad? I understand you’ve looked into Johan’s list. Have you come to any conclusions?’

Assad raised his dark eyebrows. He had something – that was plain to see. And he’d had the distinct pleasure of keeping it to himself.

‘Out with it, teacher’s pet,’ Rose said, winking at him with coal-black eyelashes.

He glanced down at his notes with a curling smile. ‘Yes, I’ve then found the woman who was assaulted in Nyborg on 13 September 1987. Her name is Grete Sonne, and she is fifty-two. She owns a clothing shop down on Vestergade. Mrs Kingsize, it’s called. I haven’t talked to her because I thought it was best if we went in person. I have the police report here. There’s not much in it about the assault that we didn’t already know.’

But enough, to judge by his facial expression.

‘The woman was thirty-two at the time and had been on the beach at Nyborg walking her dog on that autumn day. The dog had got off its lead and was running towards a treatment centre for diabetic children, a place called Skaerven. So she ran as fast as she could to catch it. The dog was a bit snappish, from what I can tell. Then there were some kids who caught up with it before she did, and approached her with the dog. There were five or six of them in all. She couldn’t remember any more than that.’

‘Ugh!’ said Rose. ‘Then it must have been a really heavy battering.’

Yes, Carl thought. Either that or the woman had lost her memory for another reason.

‘It was quite a brutal assault, all right. The report said she had been whipped on her bare skin, several of her fingers had been broken, and the dog was left dead at her side. There were plenty of footprints, but overall the clues led nowhere. There was talk that a medium-sized red car had been parked down in Sommerbyen, outside a brown summer cottage close to the water.’ Again Assad glanced down at his notes. ‘Number 50, it was. The car was parked there for a few hours. Some motorists also reported seeing a number of youths running alongside the road around the time of the assault.

‘Afterwards ferry routes and ticket sales were checked, of course, but that didn’t lead anywhere, either.’

He shrugged his shoulders regretfully, as if he had been the one leading the investigation.

‘And then, after a four-month stay in the psychiatric ward at the university hospital in Odense, Grete Sonne was released and the case was shelved as unsolved. That was that!’ He flashed a beautiful smile.

Carl put his head between his hands. ‘Well investigated, Assad, but honestly, what do you think is so special about all this?’

Again he shrugged. ‘That I have found her then. And that we can be there in twenty minutes. The shops haven’t closed yet.’

Mrs Kingsize was downtown, sixty yards from Strøget, and was very much a clothes shop with a specific aim. Here even the most shapeless woman was able to order flattering, figure-hugging, bespoke gowns in silk, taffeta and other expensive fabrics.

Grete Sonne was the only one in the boutique with a normal shape. A natural redhead with a little added gleam, she appeared quite lithe and elegant against the shop’s imposing backdrop.

She did a double take as they glided in. She had probably sparred with many drag queens and transvestites of a certain build, but this average-sized man and his little, thickset but not corpulent sidekick didn’t fit that category.

‘Yes?’ she said, glancing at the clock. ‘We’re just about to close, but if I can help you, I’ll stay on a bit.’
