‘But somebody must have seen you?’

‘Possibly, but possibly not. You see, it was horribly rough. Almost every one was sick. People, anyway, weren’t walking about.’

‘What about her maids?’

‘I did not see them.’

‘Now, Mr. Felix, what you must think over when I leave you is, first, what evidence can we get confirming your statement of how you spent your time between 11.00 and 1.30 on the Saturday night? and second, who saw you with Miss Devine on the Folkestone boat? In the meantime, please continue your statement.’

‘Bonchose met me at Charing Cross. He was keen to know how I had fared. We drove to his rooms, where I told him the whole thing. I said I would hand him the £600 on condition he broke finally with his gambling friends. He assured me the breach had already been effected, and I therefore gave him the money. We then drove to the Savoy and, after a rather early dinner, I left him and went home.’

‘At what hour?’

‘About 8.30.’

‘How did you go?’
