'Back to Bergen?' I asked.
'No. It went up the fjord towards Flamm.'
'Flamm?' The name meant something to me. I dived into the chartroom and looked at the map. Jill and Curtis crowded round me. Flamm was at the head of Aurlandsfjord. And from Flamm there was a mountain railway which had joined the main Bergen-Oslo line at Myrdal. From Myrdal he was within an hour's run of Finse. I swung round. 'Can you two ski?'
'Yes,' said Jill.
'A bit,' Curtis replied.
'Right. As soon as I've got my things together, Dick will run you up to Flamm. You may catch up with Dahler there. If so, don't let him see you. If he's gone, take the next train to Myrdal and from there catch the Oslo train to Finse. If my guess is right, you'll pick up Dahler's train there — or if not Dahler's, Jorgensen's. Wait at Finse for them. Understand?'
Curtis nodded. But I saw an obstinate look come into Jill's face. 'Where are you going?'
'Sunde and I are going up into the mountains.'
'I'm coming with you,' she said.
'No.' She began to argue, but I stopped her. 'You'll only slow us up. We've got to move fast. We've got to catch Lovaas up before he gets to Farnell. Oh, for God's sake!' I cried as she started to argue again. 'Do as I say. Follow Dahler. I know what Lovaas is up to. But I don't understand Dahler's game. For all I know he may be the more dangerous of the two.' I went down to my cabin then, calling for Dick. 'Dick,' I said. 'You'll stay with the boat. Run Jill and Curtis up to Flamm and then return here. Lie off in the fjord and keep watches. Wilson and Carter will remain with you. Don't move from here for any message whatever.'
