'You succeeded in following it?'
'Oh, yes, sir. At the Madeleine the man in front redirected the coachman, who turned to the left and drove to the Place de la Concorde, then up the Champs-Elysées to the Arch and so down the Avenue de la Grande Armée, and the Avenue de Neuilly, to the Pont de Neuilly, where it came to a standstill. My fare got out, and I saw he now wore a short black beard, which he had evidently put on inside the cab. He gave me a ten-franc piece, which was very satisfactory.
'And the fare you were following? What did he do?'
'He also stepped out, paid the cabman, went down the bank of the river and got on board a steam launch that seemed to be waiting for him.'
'Did he look behind, or appear to know that he was being followed?'
'No, sir.'
'And your fare?'
'He ran after the first man, and also went aboard the steam launch, which instantly started down the river.'
'And that was the last you saw of them?'
'Yes, sir.'
