I shook my head in answer.

“I have been half round the world, Knox, trying to find peace.”

“You don't know where to look for it,” I said.

“If only you knew,” he whispered. “If only you knew,” and sank down upon the settee, ruffling his hair with his hands and looking the picture of haggard misery. Seeing that I was still set upon departure:

“Hold on a bit, Knox,” he implored. “Don't go yet. There is something I want to ask you, something very important.”

He crossed to a sideboard and mixed himself a stiff whisky-and-soda. He asked me to join him, but I refused.

“Won't you sit down again?”

I shook my head.

“You came to my place at Katong once,” he began abruptly. “I was damned drunk, I admit it. But something happened, do you remember?”

I nodded.
