In the murder of Mr. Briggs by the German, Franz Müller, detection was greatly facilitated by the publicity given to the facts of the crime. The hat found in the railway carriage where the deed had been done was a chief clue. It bore the maker's name inside the cover, and very soon a cabman who had read this in the newspaper came forward to say he had bought that very hat at that very maker's for a man named Müller. Müller had been a lodger of his, and had given his little daughter a jeweller's cardboard box, bearing the name of "Death, Cheapside." Already this Mr. Death had produced the murdered man's gold chain, saying he had given another in exchange for it to a man supposed to be a German. There could be no doubt now that Müller was the murderer. His movements were easily traced. He had gone across the Atlantic in a sailing ship, and was easily forestalled by the detectives in a fast Atlantic liner, which also carried the jeweller and the cabman. Where identity is clear the publication of the _signalement_, if possible of the likeness, has reduced capture to a certainty; it is a mere question then of time and money. Lefroy, the murderer of Mr. Gold, was caught through the publicity given to his portrait, which had appeared in the columns of the _Daily Telegraph_. Some eminent but highly cautious police officers nevertheless deprecate the interference of the Press, and have said that the premature or injudicious disclosure of facts obtained in the progress of investigation has led to the escape of criminals. It is to be feared that there is an increasing distrust of the official methods of detection, and the Press is more and more inclined to institute a pursuit of its own when mysterious cases continue unsolved. We may yet see this system, which has sometimes been employed by energetic reporters in Paris, more largely adopted here. Without entering into the pro's and con's of such competition, it is but right to admit that the Press, with its powerful influence, its ramifications endless and widespread, has already done great service to justice in following up crime. So convinced are the London police authorities of the value of a public organ for police purposes, that they publish a newspaper of their own, the admirably managed _Police Gazette_, which is an improved form of a journal started in 1828. This gazette, which is circulated gratis to all police forces in the United Kingdom, gives full particulars of crimes and of persons "wanted," with rough but often life-like woodcut portraits and sketches that help capture. Ireland has a similar organ, the Dublin _Hue and Cry_; and some of the chief constables of counties send out police reports that are highly useful at times. Through these various channels news travels quickly to all parts, puts all interested on the alert, and makes them active in running down their prey. IV.--THE IMPORTANCE OF SMALL CLUES.
