Had no one been about to see the murder, this genial old gentleman would have gone home to his little supper-party and played the host to perfection. His "persecutor" settled with, he would probably have lived a quiet and gentle life for the remainder of his days. The "stress" being removed he might have become sane, and in his sanity he would have forgotten all about the murder he had committed.

The lunatic at large may commit murder at any time, or he may go to the end of his days without doing the slightest harm to anyone. The merest accident may stir the smouldering fire to flame. The unfortunate barmaid who was discovered murdered in a railway carriage at Waterloo Station with a bloodstained pestle was, it is believed, the victim of her resemblance to another young woman.

The theory of this crime, which still remains a mystery, is that the victim was killed by a young man who had been jilted by a girl to whom he was devotedly attached. The disappointment in love affected the man's brain. One night he entered a railway carriage, and, finding himself seated opposite the living image of the woman who had broken his heart, roused to madness by the sight of that face, he fiercely attacked the unfortunate young woman who was alone with him. Why, if the murder was not planned, he had a pestle with him, need not be argued. Whoever the murderer was he could not have calculated at the time he armed himself with a weapon that he would find himself alone with his victim in a railway carriage. The police suspected various persons at first, but later on obtained evidence which pointed strongly in the direction I have indicated. But this evidence was not sufficient to justify the suspected person being brought to trial.

Lunatics at large are not always unpleasant people; some of them are exceedingly amiable. Their amiability is, however, apt to be embarrassing. A popular tragedian who, on certain occasions, was in the habit of having wreaths handed to him across the footlights, once told me of a painful experience. An elderly lady who admired him exceedingly, determined to make him a few wreaths herself and present them to him in private life. She found out where he lived, and watched his front door. As he came out into the street she would step forward with a smile and slip a home-made wreath over his head. The tragedian didn't want to hurt the poor old lady's feelings by flinging it away, so he took it off and walked to the corner of the street with it in his hand, and then hailed a cab and drove to the theatre.

After that the old lady waylaid him almost every week, and wanted to cover him with flowers. She did succeed one day in slipping a chain of wild flowers about his neck. The great actor became nervous. He couldn't ask the police to protect him against an amiable old lady, and he didn't care to denounce her as a lunatic for considering him worthy of wreaths and garlands. Fortunately for his peace of mind the persecution suddenly ceased. What became of the old lady he never knew.

There was a dear old lady once who made me very unhappy. She lived close to me in Regent's Park, and every day she called at my house and left a few daisies or buttercups, or a handful of simple flowers. That was very nice, but when she began to stand in front of my door and make little speeches about me, scattering floral offerings on my doorstep, and putting buttercups and daisies into my letter-box, I began to feel uncomfortable. One day she went into a flower-shop in Baker Street and ordered garlands of flowers to be sent up and twined about my railings. Fortunately the lady at the flower-shop saw that the dear old soul was not right in her mind, and didn't execute the order. Some weeks after I heard that the old lady had been taken away to an asylum.

This was an agreeable form of madness; much more agreeable than the form insanity took with a young man for whom—believing the tale he told me to be true—I bought a cornet. He assured me that he could earn his living with it, and keep his poor old father and mother out of the workhouse. He came outside my house every night late—sometimes at one and two in the morning—and played that comet. And he played it very badly.

It was only after I had put someone on to follow the comet-player to his home that I discovered that he was in perfectly good circumstances—independent circumstances, in fact—but imagined that he was poor and earning his living as a street musician. He had been in a lunatic asylum for eighteen months, and had only left it a fortnight when he came to me.

Some years ago a madman took a fancy to me, with a much more painful result. He wrote me the most extraordinary letters, to which at first I replied, but I very soon discovered that my correspondent was a violent lunatic, and I ceased to acknowledge his effusions. This made no difference. They poured in upon me as freely as ever.

One day he wrote to me and enclosed the ticket of a travelling bag which he had left at Charing Cross. "I shall commit suicide to-night," he said in the letter; "I have left you my jewellery and all my securities. You will find them in the bag at Charing Cross. I enclose you the ticket for it."
