The French have been on the lookout for that sort of thing.

We haven't.
There isn't one of these men who are sitting in judgment upon us to-day, Ambrose, who would listen to me for a single moment if I were to take the bull by the horns and say that the traitor we seek is one of ourselves." "You're right," Ambrose murmured, "but do you believe it ?" "I do," Thomson asserted.
