‘No one, I’m afraid.’

‘What about the charwoman? What is her name, by the way?’

‘Mrs. Bridget Murphy. No, I don’t think she could tell where I was. You see, I practically did not see her at all. My breakfast was ready when I came down, and when I had finished I went direct to the studio. I don’t know when she went home, but I should think it was fairly early.’

‘What time did you breakfast?’

‘Eight nominally, but I wasn’t always very punctual.’

‘Do you remember, and have you any way of proving, what time you had breakfast on this particular Wednesday?’

Felix thought over the question.

‘No,’ he answered, ‘I don’t think so. There was nothing to distinguish that morning from the others.’

‘The point is important. Perhaps Mrs. Murphy would remember?’

‘Possibly, but I hardly think so.’
