'But that doesn't mean it isn't him,' Jon had answered, and they had nodded, taken notes and led him out.
'Are you sure the police won't let you sleep in your own flat?' Thea asked. 'There'll be so much gossip if you stay here tonight.'
'It's a murder scene,' Jon said. 'It's sealed until they've finished the investigation.'
'Sealed,' she said. 'It sounds like a letter.'
Bette Davis ran towards the younger woman and the violins upped the volume and the drama.
'What are you thinking about?' Thea asked.
Jon didn't answer. He didn't answer that he was thinking about the moment he had lied to her when he said it was all over. It wouldn't be over until he had done what he had to do. And what he had to do was take the bull by the horns, block the enemy, be a courageous little soldier. Because now he knew. He had been standing so close to Halvorsen when he played back the message from Mads Gilstrup that he had heard the confession.
The doorbell rang. She stood up as though it was a welcome interruption. It was Rikard.
'Am I disturbing?' he asked.
'No,' Jon said. 'I was on my way out.'
Jon put on his outdoor clothing in the threefold silence. After closing the door behind him he stood for a few seconds listening to the voices inside. They were whispering. Why were they whispering? Rikard sounded angry.
He caught the tram to town and took the Holmenkollen line from there. At the weekend with snow on the fields the train would usually have been full of cross-country skiers, but it must have been too cold for most today. He got off at the last station and observed Oslo nestling a long way below.
Mads and Ragnhild's home was situated on a hill. Jon had never been there before. The gate was quite narrow and so was the drive curving round a clump of trees which hid most of the house from the road. The house itself was low and built in such a way that you didn't notice how big it was until you were inside and walking around. At least that was what Ragnhild had said.
Jon rang and after a few seconds he heard a voice from a speaker he could not see. 'Well, I never. Jon Karlsen.'
Jon looked at the camera over the door.
'I'm in the living room.' Mads Gilstrup's voice sounded slurred and he was chuckling. 'I assume you know the way.'
The door opened automatically and Jon Karlsen stepped into a hall the size of his flat.
'Hello?'
He received a short, harsh echo by way of an answer.
He began to walk down a corridor he assumed would culminate in a living room. Unframed canvases covered in vivid oil colours hung on the walls. And there was a particular smell that got stronger the further he advanced. He passed a kitchen with a cooking island and a dining table surrounded by a dozen chairs. The sink was full of plates, glasses and empty bottles of booze. There was a sickly smell of stale food and beer. Jon continued. Clothes lay strewn along the corridor. He peered through the door to a bathroom. There was a stench of vomit.
He rounded a corner and was presented with the kind of panorama of Oslo and the fjord that he had seen when he and his father had gone for walks in Nordmarka.
A screen had been set up in the middle of the room and images from what was evidently an amateur video of a wedding rolled silently across the white canvas. The father led the bride up the aisle as she nodded and smiled to guests on both sides. The gentle hum of the projector fan was all that could be heard. In front of the screen he saw the rear of a black, high-backed armchair and two empty – and one half empty – bottles on the floor beside it.
Jon announced himself with a loud cough and went closer.
The chair swivelled round slowly.
And Jon came to an abrupt halt.
A man he half recognised as Mads Gilstrup was sitting in the chair. He was wearing a clean, white shirt and black trousers, but he was unshaven and his face was bloated, his eyes blanched with a chalky grey film over them. In his lap was a double-barrelled rifle with intricate carvings of animals on the burgundy gunstock. The way he sat it was pointing at Jon.
'Do you hunt, Karlsen?' Gilstrup asked gently in a hoarse, alcoholdrenched voice.
Jon shook his head, unable to take his eyes off the rifle. 'In our family we hunt everything,' Gilstrup said. 'No game too small, none too big. I think you could say that is our family motto. My father has shot everything on four legs. Every winter he travels to a country where there are animals he has not yet shot. Last year it was Paraguay where there was said to be a rare forest puma. I am no great shakes myself. Not according to Father. He says I don't have the necessary cold-bloodedness. He used to say that the only animal I was capable of catching was her.' Gilstrup flicked his head towards the screen. 'Although I suspect he thought she was the one who caught me.'
Gilstrup placed the rifle on the coffee table beside him and opened his palm. 'Take a seat. We're due to sign a contract with your boss David Eckhoff this week. Transferring the properties in Jacob Aalls gate, first of all. Father will thank you for recommending the sale.'
