Regarding the work of the detective as a spy (which probably constitutes seventy-five per cent of his employment to-day), few persons realize how widely such services are being utilized. The insignificant old Irishwoman who stumbles against you in the department store is possibly watching with her cloudy but eagle eye for shoplifters. The tired-looking man on the street-car may, in fact, be a professional “spotter.” The stout youth with the pince-nez who is examining the wedding presents is perhaps a central-office man. All this you know or may suspect. But you are not so likely to be aware that the floor-walker himself is the agent of a rival concern placed in the department store to keep track, not only of prices but of whether or not the wholesalers are living up to their agreements in regard to the furnishing of particular kinds of goods only to one house; or that the conductor on the car is a paid detective of the company, whose principal duty is not to collect fares, but to report the doings of the unions; or that the gentleman who is accidentally introduced to you at the wedding breakfast is employed by a board of directors to get a line on your host’s business associates and social companions.

In the great struggle between capital and labor, each side has expended large sums of money in employing confederates to secure secret information as to the plans and doings of the enemy. Almost every labor union has its Judas, and many a secretary to a capitalist is in the secret employment of a labor union. The railroads must be kept informed of what is going on, and, if necessary, they import a man from another part of the country to join the local organization. Often such men, on account of their force and intelligence, are elected to high office in the brotherhoods whose secrets they are hired to betray. Practically every big manufacturing plant in the United States has on its pay-rolls men acting as engineers, foremen, or laborers who are drawing from $80 to $100 per month as detectives either (1) to keep their employers informed as to the workings of the labor unions, (2) to report to the directors the actual conduct of the business by its salaried officers, superintendents, and overseers, or (3) to ascertain and report to outside competing concerns the methods and processes made use of, the materials utilized, and the exact cost of production.

There are detectives among the chambermaids and bellboys in the hotels, and also among the guests; there are detectives on the passenger lists and in the cardrooms of the Atlantic liners; the colored porter on the private car, the butler at your friend’s house, the chorus girl on Broadway, the clerk in the law office, the employee in the commercial agency, may all be drawing pay in the interest of some one else, who may be either a transportation company, a stock-broker, a rival financier, a yellow newspaper, an injured or even an erring wife, a grievance committee, or a competing concern; and the duties of these persons may and will range from the theft of mailing-lists, books, and papers, and (in the case of the newspaper) of private letters, up to genuine detective work requiring some real ability.

Apart from the hired thieves above referred to, some yellow journals employ men to work upon the various “mystery stories” that from time to time arouse the attention of the public, who often accomplish as good results as the police. I should, however, place one limitation upon this general statement, which is that, as the object of the newspaper is usually quite as much to keep the story alive as to solve the mystery, the papers are apt to find startling significance in details of slight importance. While we are speaking of newspapers, it may not be out of place to suggest that their activity is such that there are few general evils left undisclosed and few prominent men the privacy of whose lives is not known in the editorial rooms. When lurid tales are told of the secret doings of Mr. So-and-So and the Hon. This and That, you may rest assured that the greater the desirability of those yarns as copy for the big dailies, the less likely they are to have any foundation in fact. The eye of the city editor is in every place discerning the evil if not the good. Indeed, it is almost unnecessary for the papers to hire spies, since self-constituted ones are ready at any moment to bargain with them for stolen goods and ruined reputations.

Detective work of the sort which involves the betrayal of confidences and friendships naturally excites our aversion—yet in many cases the end undoubtedly justifies the means employed, and often there is no other way to avert disaster and prevent fiendish crimes. Sometimes, on the other hand, the information sought is purely for mercenary or even less worthy reasons, and those engaged in these undertakings range from rascals of the lowest type to men who are ready to risk death for the cause which they represent and who are really heroes of a high order. One of the latter with whom I happened to be thrown professionally was a young fellow of about twenty named Guthrie.

It was during a great strike, and outrages were being committed all over the city of New York by dynamiters supposed to be in the employ of the unions. Young Guthrie, who was a reckless dare-devil, offered his services to the employers, and agreed (for a trifling compensation) to join one of the local unions and try to find out who were the men blowing up office buildings in process of construction and otherwise terrorizing the inhabitants of the city. The story of his success deserves a chapter by itself, and it is enough here to state that he applied for membership in the organization, and by giving evidence of his courage and fiber managed to secure a place as a volunteer in the dynamiting squad. So cleverly did he pass himself off as a bitter enemy of capital that he was entrusted with secrets of the utmost value and took part in making the plans and procuring the dynamite to execute them. The quality of his nerve (as well as his foolhardiness) is shown by the fact that he once carried a dress-suit case full of the explosive around the city, jumping on and off street cars, and dodging vehicles. When the proper moment came and the dynamite had been placed in an uncompleted building on Twenty-second Street, Guthrie gave the signal and the police arrested the dynamiters—all of them, including Guthrie, who was placed with the rest in a cell in the Tombs and continued to report to the district attorney all the information which he thus secured from his unsuspecting associates. Indeed, it was hard to convince the authorities that Guthrie was a spy and not a mere accomplice who had turned State’s evidence, a distinction of far-reaching legal significance so far as his evidence was concerned.

The final episode in the drama was the unearthing by the police of Hoboken of the secret cache of the dynamiters, containing a large quantity of the explosive. Guthrie’s instructions as to how they should find it read like a page from Poe’s “Gold Bug.” You had to go at night to a place where a lonely road crossed the Erie Railroad tracks in the Hackensack meadows, and mark the spot where the shadow of a telegraph pole (cast by an arc light) fell on a stone wall. This you must climb and walk so many paces north, turn and go so many feet west, and then north again. You then came to a white stone, from which you laid your course through more latitude and longitude until you were right over the spot. The police of Hoboken did as directed, and after tacking round and round the field, found the dynamite. Of course, the union said the whole thing was a plant, and that Guthrie had put the dynamite in the field himself at the instigation of his employers, but before the case came to trial both dynamiters pleaded guilty and went to Sing Sing. One of them turned out to be an ex-convict, a burglar. I often wonder where Guthrie is now. He certainly cared little for his life. Perhaps he is down in Venezuela or Mexico. He could never be aught than a soldier of fortune. But for a long time the employers thought that Guthrie was a detective sent by the unions to compromise them in the very dynamiting they were trying to stop!

I once had a particularly dangerous and unfortunate case where a private client was being blackmailed by a half-crazy ruffian who had never seen him, but had selected him arbitrarily, as a person likely to give up money. The blackmailer was a German Socialist, who was out of employment—a man of desperate character. He had made up his mind that the world owed him a living, and he had decided that the easiest way to get it was to make some more prosperous person give him a thousand dollars under threat of being exposed as an enemy of society.

The charge was so absurd as to be almost ludicrous, but had my client caused the blackmailer’s arrest the matter would have been the subject of endless newspaper notoriety and comment. It was therefore thought wise to make use of other means, and I procured the assistance of a young German-American of my acquaintance, who, in the guise of a vaudeville artist seeking a job, went to the blackmailer’s boarding-house and pretended to be looking for an actor friend with a name not unlike that of the criminal.

After two or three visits he managed to scrape an acquaintance with the blackmailer and thereafter spent much time with him. Both were out of work, both were Germans, and both liked beer. My friend had just enough money to satisfy this latter craving. In a month or so they were intimate friends and used to go fishing together down the bay. At last, after many months, the criminal disclosed to the detective his plan of blackmailing my client, and suggested that as two heads were better than one they had better make it a joint venture. The detective pretended to balk at the idea at first, but was finally persuaded, and at the other’s request undertook the delivery of the blackmailing letters to my client! Inside of three weeks he had in his possession enough evidence in the criminal’s own handwriting to send him to prison for the rest of his life. When at last the detective disclosed his identity the blackmailer at first refused to believe him, and then literally rolled on the floor in his agony and fear at discovering how he had been hoodwinked. The next day he disappeared and has not been heard of since, but his letters are in my vault, ready to be used if he again puts in an appearance.
