I could not expect him to believe a word.
"At last he told me to sit down in the chair opposite his chair, and I said, 'With pleasure.' Then he said, 'We'd better have a drink, because only one of us is coming out of this room alive,' and I said the same thing again.

He was full of drink already, but not drunk, and my own head was as light as air.

I was ready for anything.

He unlocked a drawer and took a brace of old revolvers from the case in which I put them away again.

I locked up the drawer afterwards, and put his keys back in his pocket, before losing my head and doing all the rest that the police saw through at a glance.
