For example, if you are receiving anonymous letters, the writer of which accuses you of all sorts of unpleasant things, you would, of course, much prefer to find out who it is and stop him quietly than to turn over the correspondence to the police and let the writer’s attorneys publicly cross-examine you at his trial as to your past career. Even if a diamond necklace is stolen from a family living on Fifth Avenue, there is more than an even chance that the owner will prefer to conceal her loss rather than to have her picture in the morning paper. Yet she will wish to find the necklace if she can.
When the matter has no criminal side at all, the police cannot be availed of, although we sometimes read that the officers of the local precinct have spent many hours in trying to locate Mrs. So-and-So’s lost Pomeranian, or in performing other functions of an essentially private nature—most generously. But if, for example, your daughter is made the recipient, almost daily, of anonymous gifts of jewelry which arrive by mail, express, or messenger, and you are anxious to discover the identity of her admirer and return them, you will probably wish to engage outside assistance.
Where will you seek it? You can do one of two things: go to a big agency and secure the services of the right man, or engage such a man outside who may or may not be a professional detective. I have frequently utilized with success in peculiar and difficult cases the services of men whom I knew to be common-sense persons, with a natural taste for ferreting out mysteries, but who were not detectives at all. Your head book-keeper may have real talents in this direction—if he is not above using them. Naturally, the first essential is brains—and if you can give the time to the matter, your own head will probably be the best one for your purposes. If, then, you are willing to undertake the job yourself, all you need is some person or persons to carry out your instructions, and such are by no means difficult to find. I have had many a case run down by my own office force—clerks, lawyers, and stenographers, all taking a turn at it. Why not? Is the professional sleuth working on a fixed salary for a regular agency and doing a dozen different jobs each month as likely to bring to bear upon your own private problem as much intelligence as you yourself?
There is no mystery about such work, except what the detective himself sees fit to enshroud it with. Most of us do detective work all the time without being conscious of it. Simply because the matter concerns the theft of a pearl, or the betraying of a business or professional secret, or the disappearance of a friend, the opinion of a stranger becomes no more valuable. And the chances are equal that the stranger will make a bungle of it.
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.
