‘I called up Daisy half an hour after we found him, called her instinctively and without hesitation. But she and Tom had gone away early that afternoon, and taken baggage with them.’
‘Left no address?’
‘Say when they’d be back?’
‘Any idea where they are? How I could reach them?’
‘I don’t know. Can’t say.’

F. Scott Fitzgerald
