My feeling of benevolence towards all created things, the result of my successful handling of the Little Nugget, embraced Sam. I invited him in.

'Well,' I said, when I had given him a cigar and filled his glass, 'and how have you been getting on, Mr Fisher? Any luck?'

He shook his head at me reproachfully.

'Young man, you're deep. I've got to hand it to you. I underestimated you. You're very deep.'

'Approbation from Smooth Sam Fisher is praise indeed. But why these stately compliments?'

'You took me in, young man. I don't mind owning it. When you told me the Nugget had gone astray, I lapped it up like a babe. And all the time you were putting one over on me. Well, well!'

'But he had gone astray, Mr Fisher.'

He knocked the ash off his cigar. He wore a pained look.

'You needn't keep it up, sonny. I happened to be standing within three yards of you when you got into a cab with him in Shaftesbury Avenue.'

I laughed.
