‘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?’
