'And who's in charge of this expedition?'

'You are,' he answered reluctantly.

'Right,' I said. 'Now get that dinghy slung over the side. We meet up here on deck at eleven-thirty — the three of us; you, Dick and I. Warm clothes and rubber shoes. I'll look after the girl.'

For a moment I thought he was going to argue. But the long habit of obedience to command was stronger than his sudden outburst of conscience. He turned and began to haul the dinghy over the rail.

At supper that night everybody seemed unnaturally quiet. Jill ate in silence, her eyes on her plate. Only Dahler was talkative. I wondered who he had telephoned from the hotel. 'What is your next move, Mr Gansert?' he asked me quite suddenly.

'Wait for Sunde's partner,' I answered.

'It is a pity Mr Sunde will not talk without his partner.' His eyes met mine. Some devil of laughter was there in the dark pupils. He glanced at Sunde.

The diver looked up quickly. Then his eyes fell to his plate again. He seemed nervous.

Dahler smiled. An unnatural excitement emanated from the man.

After the meal, I got everyone off to bed. It had been a long day and they were tired. Moreover, the sudden transfer from coast to mountain air had made us all sleepy.
