Patrik hesitated, but another honk from the second police car prompted him to make up his mind.

‘Okay, I’ll wander over, just to take a look. But you’ll have to watch Maja while I go inside. And not a word to Erica about this. She’d be furious if she found out that I took Maja to a possible crime scene.’

‘I promise,’ said Martin, winking. He waved to Bertil and Gösta and shifted into first. ‘See you there.’

‘Okay,’ said Patrik, with a strong feeling that this was something he was going to regret. But curiosity won out over his instinct for self-preservation; he turned the pushchair around and began swiftly heading for Hamburgsund.

‘Everything made of pine has to go!’ Anna was standing with her hands on her hips, trying for as stern an expression as she could muster.

‘What’s wrong with pine?’ said Dan, scratching his head.

‘It’s ugly! How can you even ask such a question?’ said Anna, but she couldn’t help laughing. ‘Don’t look so scared, love… But I really am going to have to insist. There’s nothing uglier than furniture made of pine. And that bed is the worst of all. Besides, I don’t want to go on sleeping in the same bed that you shared with Pernilla. I can live in the same house, but I can’t sleep in the same bed.’

‘That’s something I can understand. But it’s going to be expensive to buy a lot of new furniture.’ He looked worried. When he and Anna became a couple, he’d abandoned plans to sell the house, but it was still proving difficult to make ends meet.

‘I have the cash that I got from Erica when she bought my share of our parents’ house. Let’s use some of it to buy new things. We can do it together, or you can give me free rein – if you dare.’

‘Believe me, I’d rather not make decisions about furniture,’ said Dan. ‘As long as it’s not too outrageous, you can buy whatever the heck you want. Enough talk, come over here and give me a hug.’

As usual, things started to get hot and heavy, and Dan was just unhooking Anna’s bra when someone pulled open the front door and came in. Since there was a good view of the kitchen from the hall, there was no question of what was going on.

‘Jesus, how disgusting! I can’t believe you’re actually making out in the kitchen!’ Belinda stormed past and made for her room, her face bright red with fury. At the top of the stairs she stopped and shouted:

‘I’m going back to live with Mamma as soon as I can – do you hear me? At least there I won’t have to watch the two of you sticking your tongues down each other’s throats all the time! It’s gross! Do you hear me?’

Bang! The door to Belinda’s room slammed shut, and they heard the key turn. A second later the music started up, so loud that it made the plates on the counter jump and clatter to the beat.

‘Oops,’ said Dan with a wry expression as he looked up at the ceiling.

‘Yes, “oops” is the right word for it,’ Anna said, pulling out of his arms. ‘This really isn’t easy for her.’ She picked up the clinking plates and put them in the sink.

‘I know, but she’s just going to have to accept that I have a new woman in my life,’ said Dan, sounding annoyed.

‘Just try and put yourself in her position. First you and Pernilla get divorced, then a whole lot of…’ – she weighed her words carefully – ‘girlfriends come waltzing through here, and then I appear on the scene and move in with two little kids. Belinda is barely seventeen, which is tough enough, without having to get used to three strangers moving in.’

‘You’re right, I know that,’ said Dan with a sigh. ‘But I have no idea how to deal with a teenager. I mean, should I just leave her alone, or will that make her feel neglected? Or should I insist on talking to her and then risk having her think I’m pressuring her? There should be a manual for situations like this.’

Anna laughed. ‘I think they forgot about handing out manuals back in the maternity ward. But you could try talking to her. If she slams the door in your face, at least you’ve given it a try. And then you should try again. And again. She’s afraid of losing you. She’s afraid of losing the right to be a child. She’s afraid that we’re going to take over everything now that we’ve moved in. And that’s perfectly understandable.’

‘What did I do to deserve such a wise woman?’ said Dan, pulling Anna close again.

‘I don’t know,’ said Anna, smiling as she burrowed her face into his chest. ‘Mind you, I’m not particularly wise. It just seems that way, compared to your previous conquests.’

‘Hey, watch out,’ said Dan with a laugh as he wrapped his arms tighter around her. ‘If you keep that up, I might decide to hang on to the pine bed after all.’

‘So do you want me to stay here or not?’

‘Okay. You win. Consider it gone.’

They both laughed. And kissed. Overhead the pop music continued to pound, turned up to a deafening volume.

Martin saw the boys as soon as he turned on to the drive in front of the house. They were standing off to the side, both of them hugging their arms to their bodies and shivering. Their faces were pale, and they looked visibly relieved when they caught sight of the police cars.

‘Martin Molin,’ he said, shaking the hand of the first boy, who introduced himself as Adam Andersson, mumbling the name. The other boy waved his right hand, offering an apology with an embarrassed expression.

‘I threw up and wiped it off with my… Well, I don’t think I should shake hands.’

Martin nodded sympathetically. ‘All right, so what exactly happened here?’ He turned to Adam, who seemed more composed. He was shorter than his friend, with shaggy blond hair and an angry outbreak of acne on his cheeks.

‘Well, the thing is, we…’ Adam glanced over at Mattias, who merely shrugged, so he went on. ‘Well, we were thinking of going inside the house to have a look around, since it looked like the old guys had gone away.’

‘Old guys?’ said Martin. ‘So two people live here?’

Mattias replied, ‘Two brothers. I don’t know what their first names are, but my mother probably does. She’s been taking in their post since the beginning of June. One of the brothers always goes away during the summer, but not the other one. Except this time no one was taking in the post from the letter box, so we thought that…’ He left the rest of the sentence unspoken and looked down at his feet. A dead fly was still lying on one shoe. He kicked out in disgust, trying to knock it off. ‘Is he the one who’s dead inside the house?’ he said then, looking up.

‘At the moment you know more than we do,’ said Martin. ‘But go on. You were thinking of going inside, and then what happened?’

‘Mattias found a window that was open, and he climbed in first,’ said Adam. ‘Seems funny now, because when we came out we discovered that the front door was unlocked. So we could just as well have walked right in. Anyway, Mattias climbed in through the window and pulled me up after him. When we jumped down on to the floor, we noticed something crunching under our feet, but we didn’t see what it was because it was too dark.’

‘Dark?’ Martin interrupted him. ‘Why was it dark?’ Out of the corner of his eye he saw that Gösta, Paula and Bertil were now standing behind him, listening.

‘All the blinds were down,’ Adam explained patiently. ‘But we rolled up the blind of the window we’d come through. And then we saw that the floor was covered with dead flies. And the smell was horrible.’

‘Really awful,’ Mattias chimed in, looking as if he was fighting off another wave of nausea.

‘Then what?’ Martin said, in an effort to keep them on track.

‘Then we went further into the room, and the chair behind the desk was turned so the back was facing us, and we couldn’t tell what was there. But I had a feeling that… well, I’ve seen CSI, and with such an awful smell and all those dead flies… you don’t have to be Einstein to figure out that something had died in there. So I went over to the chair and turned it around. And there he was!’
