‘Did I say you could touch anything?’ the officer said without turning.
Bjørn hurriedly put back the rope.
‘OK, boss,’ Harry said, sending Skai a closed smile. ‘Can we touch anything?’
The officer weighed Harry up. ‘You still haven’t told me what kind of case this is.’
‘It’s confidential,’ Harry said. ‘Sorry. Fraud Squad. You know.’
‘That right? If you’re the Harry Hole I think you are, you used to work on murders.’
‘Well,’ Harry said, ‘now it’s insider trading, tax evasion and fraud. One moves upwards in life.’
Officer Skai pinched an eye shut. A bird shrieked.
‘Of course, you’re right, Skai,’ Kaja said with a sigh. ‘But I’m the person who has to deal with the red tape for the search warrant from the police solicitor. As you know, we’re understaffed and it would save me a lot of time if we could just . . .’ She smiled with her tiny, pointed teeth and gestured towards the coil of rope.
Skai looked at her. Rocked to and fro on his rubber heels a couple of times. Then he nodded.
‘I’ll wait in the boat,’ he said.
Bjørn set to work immediately. He placed the coil on the long table, opened the little rucksack he had with him, switched on a torch attached to a cord with a fish hook on the end and secured it into position between two boards in the ceiling. He took out his laptop and a portable microscope shaped like a hammer, plugged the microscope into the USB port on the laptop, checked it was transmitting pictures to the screen and clicked on an image he had transferred to the laptop before they departed.
Harry stood beside the bride and gazed down at the lake. In the boat he could see the glow of a cigarette. He eyed the rails that went down into the water. The deep end. Harry had never liked swimming in fresh water, especially after the time he and Øystein had skipped school, gone to Lake Hauktjern in Østmarka and jumped off the Devil’s Tip, which people said was twelve metres high. And Harry – seconds before he hit the water – had seen a viper gliding through the depths beneath him. Then he was enveloped by the freezing cold, bottle-green water and in his panic he swallowed half the lake and was sure he would never see daylight or breathe air again.
Harry smelt the fragrance that told him Kaja was standing behind him.
‘Bingo,’ he heard Bjørn Holm whisper.
Harry turned. ‘Same type of rope?’
‘No doubt about it,’ Bjørn said, holding the microscope against the rope end and pressing a key for high-resolution images. ‘Linden and elm. Same thickness and length of fibre. But the bingo is reserved for the recently sliced rope end.’
‘What?’
Bjørn Holm pointed to the screen. ‘The photo on the left is the one I brought with me. It shows the rope from Frogner Lido, magnified twenty-five times. And on this rope I have a perfect . . .’
Harry closed his eyes so as to relish to the full the word he knew was coming.
‘… match.’
He kept his eyes closed. The rope Marit Olsen was hung with had not only been made here, it had been cut from the rope they had before them. And it was a recent cut. Not so long ago he had been standing where they were standing. Harry sniffed the air.
An all-embracing darkness had fallen. Harry could hardly make out anything white in the window as they left.
Kaja sat at the front of the boat with him. She had to lean close so that he could hear her over the drone of the motor.
‘The person who collected the rope must have known his way around this area. And there can’t be many links in the chain between that person and the killer . . .’
‘I don’t think there are any links at all,’ Harry said. ‘The cut was recent. And there are not many reasons for rope to change hands.’
‘Local knowledge, lives nearby or has a cabin here,’ Kaja mused aloud. ‘Or he grew up here.’
‘But why come all the way to a disused ropery to get a few metres of rope?’ Harry asked. ‘How much does a long rope cost in a shop? A couple of hundred kroner?’
‘Perhaps he happened to be in the vicinity and knew the rope was there.’
‘OK, but in the vicinity would mean he must have been staying in one of the nearby cabins. For everyone else it’s a fair old boat trip. Are you making … ?’
‘Yes, I’m making a list of the closest neighbours. By the way, I tracked down the volcano expert you asked for. A nerd up at the Geological Institute. Felix Røst. He seems to do a bit of volcano-spotting. Travelling all over the world to look at volcanoes and eruptions and that sort of thing.’
