“You forget, Mr. Thorndyke,” the chief said firmly, “that at the present moment you are a member of my force, and that you go to this place in that capacity, and not as Squire of Crowswood; therefore you must, if you please, do as I instruct you. The gentleman will be ready to pay that sum. As you see, the amounts entered here total up to nearly 10,000 pounds. He said that it will ruin him to pay that sum, but that he must do so rather than his son should be branded as a defaulter. I have advised him to write to all these people saying that it will take him some time to raise the money, but that he will see that nobody shall be a loser by his son's debts. I have told him in the meantime that I will endeavor to get proof that the play was not fair, and in that case he would, of course, refuse to pay any of the claims on that ground; and you may be sure that if unfair play was proved none of those concerned would dare to press their claims.” “Then my function would be simply to watch?” “Yes, to watch, and to bring me word of anything you may observe. You see, without making a public scandal, if it could be found that a man was discovered cheating, and the way in which he was doing it, one would be able to put so strong a pressure on him, that not only might he be forced to abstain from going to any club, but would be frightened into giving up any IOUs he might hold.” “I shall be glad to do the best I can, sir; but frankly I know next to nothing of cards, and should have but little chance of detecting anything that might be going on, when it must be done so cleverly that experienced gamblers, watching a man closely, fail to see anything wrong.” “I quite understand that; but one of my men has made a study of the various methods employed by gamblers to cheat, and although it would take you years to learn how to do it yourself, a few hours' instruction from him would at least put you up to some of their methods, and enable you to know where to look for cheating. The man is now waiting in the next room, and if you will take two or three hours daily with him, say for a week, you ought to be able to detect the doings of these fellows when to others everything seems right and above board. You may have no inclination for cards, but knowledge of that sort is useful to anyone in society, here or anywhere else, and may enable him either to save his own pocket or to do a service to a friend.”
