‘Yes, about then.’

‘And at what time did you yourself leave?’

‘About quarter to twelve.’

‘Then your conversation lasted about three-quarters of an hour. Now, did any one see you leave?’

‘No one except Annette. She came to the door with me.’

‘You returned to your hotel, I suppose?’

‘Yes.’

‘At what hour did you reach it?’

‘About half-past one, I should say.’

‘From Madame’s house to the Hotel Continental is about fifteen minutes’ walk. What, then, did you do in the interval?’
