FRENCH DETECTIVES.

‘The Secret Police’ in France are not only personally unknown to the general public, but, save in exceptional cases, even to each other. It is known where they may be found at a moment’s notice when wanted; but, as a rule, they do not frequent the prefecture more than can be helped. They have nothing whatever to do with serving summonses or executing warrants. There are among them men who have lived in almost every class of life, and each of them has what may be called a special line of business of his own. In the course of their duty, some of them mix with the receivers of stolen goods, others with thieves, many with what are called in Paris commercial rascals, and not a few with those whose ‘industry’ it is to melt silver and other property of a like valuable nature. Forgers, sharpers of all kinds, housebreakers and horse-stealers—a very numerous class in Paris—have each all their special agents of the police, who watch them, and know where to lay hands upon them when they are wanted. A French detective who cannot assume and act up to any character, and who cannot disguise himself in any manner so effectually as not to be recognised even by those who know him best, is not considered fit to hold his appointment. Their ability in this way is marvellous. Some years ago, one of them made a bet that he would in the course of the next few days address a gentleman with whom he was acquainted four times, for at least ten minutes each time, and that he should not know him on any occasion until the detective had discovered himself. As a matter of course, the gentleman was on his guard, and mistrusted every one who came near him. But the man won his bet. It is needless to enter into the particulars. Suffice it to say that in the course of the next four days he presented himself in the character of a bootmaker’s assistant, a fiacre-driver, a venerable old gentleman with a great interest in the Bourse, and finally as a waiter in the hotel in which the gentleman was staying.
