Many of the best available detectives are men who work by themselves without any permanent staff, and who have their own regular clients, generally law firms and corporations. Almost any attorney knows several such, and the chief advantage of employing one of them lies in the fact that you can learn just what their abilities are by personal experience. They usually command a high rate of remuneration, but deductive ability and resourcefulness are so rare that they are at a premium and can only be secured by paying it. These men are able, if necessary, to assume the character of a doctor, traveller, man-about-town, or business agent without wearing in their lapels a sign that they are detectives, and they will reason ahead of the other fellow and can sometimes calculate pretty closely what he will do. Twenty-five dollars a day will generally hire the best of them, and they are well worth it. The detective business swarms with men of doubtful honesty and morals, who are under a constant temptation to charge for services not rendered and expenses not incurred, who are accustomed to exaggeration if not to perjury, and who have neither the inclination nor the ability to do competent work. Once they get their clutches on a wealthy client, they resemble the shyster lawyer in their efforts to bleed him by stimulating his fears of publicity and by holding out false hopes of success, and thus prolonging their period of service. An unscrupulous detective will, almost as a matter of course, work on two jobs at once and charge all his time to each client. He will constantly report progress when nothing has been accomplished, and his expenses will fill pages of his notebook. Meantime his daily reports will fall like a shower of autumn leaves. In no profession is it more essential to know the man who is working for you. If you need a detective, get the best you can find, put a limit on the expense, and give him your absolute confidence.
