"In that case," answered Bandy, without a moment's hesitation, "all bets would be off. The gentleman in custody would make a cry that would be heard in every detective bureau in America. There would be an immediate decrease in the population of crooks. Why, I know enough about Sandy to get his neck——" he stopped suddenly.

"And was this, too, understood by the gang?"

Bandy shifted uneasily on his seat.

"You make me weary—honest you do, Cig. What's the matter with you? You know just as well as I do that every gang of crooks knows just what I've been telling you. If it weren't true, what's to keep them from squealing every time they get arrested?"

In this last sentence Bandy summed up the whole question of honor among thieves, and for this reason I have told the foregoing at some length. The repentance of a thief rarely, if ever, includes restitution. This statement anyhow applies to the veterans. With the younger men it is somewhat otherwise, and then usually through the administrations of the prison chaplain. But after having served a prison term for the first time the young crook adopts the sophistry and cynicism of his elders in crime. The only time that a thief feels regret for his misdeeds is when the latter has been fruitless, or when the proceeds have been lost to him.

What I have said about crooks not peaching on each other does not apply to the professional stool-pigeon, or "mouthpiece," who, by the way, is part and parcel of every police force in every city and town in this country and abroad. But these fellows can hardly be classed as genuine crooks, at least in the great majority of instances. They are rather the Pariahs of the Under World—hated, despised and tolerated for precisely the same reason that curs are allowed to roam through the streets.

It goes without saying that as long as the "mouthpiece" forms an integral part of the police system of civilization, so long will there be a real, although not admitted, alliance between the Powers that Prey and the Powers that Rule, with an incidental weakening and demoralization of the latter.

Finally, there are times and seasons in which the Under World of its own volition gives up an offender. But these occasions are rare, and only when it is felt that the individual must be sacrificed for the good of the community. Usually there is a political pact in these rare happenings.
