I am referring, Monsieur, to the incident in the cab last night.” “Yes, I understand.” Mr. Smith nodded. “The other day, when we discovered that you are who you are, we allowed you to go, Monsieur, and said nothing about the girl who also has been seeking M. Clarke. If you were not M. Clarke, then M. Clarke remained to be found. ”
