‘About nine-thirty.’

‘What café did you lunch at in Charenton?’

‘I don’t remember. It was in a street about half-way between the station and the steamboat wharf, a rather poor place with an overhanging, half-timbered front.’

‘And what time was that?’

‘About one-thirty, I think. I am not sure.’

‘And from where did you telephone to your house and office?’

‘From the same café.’

‘About what time?’

‘About an hour later, say half-past two.’

‘Now, the café in the Place de la Bastille. Which one was it?’
