Derues said to a man who was looking at a picture in the Palais de Justice: "Why study copies of Nature when you can look at such a remarkable original as I?" A judge once told the present writer that he did not go often to the theatre because none of the dramas which he saw on the stage, seemed to him equal in intensity to those of real life which came before him in the course of his duties. The saying that truth is stranger than fiction applies more forcibly to crime than to anything else. But the ordinary man and woman prefer to take their crime romanticised, as it is administered to them in novel or play. The true stories told in this book represent the raw material from which works of art have been and may be yet created. The murder of Mr. Arden of Faversham inspired an Elizabethan tragedy attributed by some critics to Shakespeare. The Peltzer trial helped to inspire Paul Bourget's remarkable novel, "Andre Cornelis." To Italian crime we owe Shelley's "Cenci" and Browning's "The Ring and the Book." Mrs. Manning was the original of the maid Hortense in "Bleak House." Jonathan Wild, Eugene Aram, Deacon Brodie, Thomas Griffiths Wainewright have all been made the heroes of books or plays of varying merit. But it is not only in its stories that crime has served to inspire romance. In the investigation of crime, especially on the broader lines of Continental procedure, we can track to the source the springs of conduct and character, and come near to solving as far as is humanly possible the mystery of human motive. There is always and must be in every crime a terra incognita which, unless we could enter into the very soul of a man, we cannot hope to reach. Thus far may we go, no farther. It is rarely indeed that a man lays bare his whole soul, and even when he does we can never be quite sure that he is telling us all the truth, that he is not keeping back some vital secret. It is no doubt better so, and that it should be left to the writer of imagination to picture for us a man's inmost soul. The study of crime will help him to that end. It will help us also in the ethical appreciation of good and evil in individual conduct, about which our notions have been somewhat obscured by too narrow a definition of what constitutes crime. These themes, touched on but lightly and imperfectly in these pages, are rich in human interest. And so it is hardly a matter for surprise that the poet and the philosopher sat up late one night talking about murders. The Life of Charles Peace
