That answer is typical of the public attitude towards lunatics at large. Unless they have killed or attempted to kill it is nobody's business to have them, in the interests of public safety, certified as insane.

We shudder at Caliban when we see him on the stage, and we tremble for Miranda. But there are dozens of Calibans in London, and they are free to roam where they like night and day.

Come down this court with me. Here is a monster deaf and dumb and deformed. Look at the hideous grimaces he makes, listen to the horrible sounds he utters. He is eight and twenty, and has lived in this court for ten years with his mother and father. #

The children tease him. Occasionally they irritate him to such an extent that with a series of wild howls he rushes at them. Then they run away, and presently an aged woman will come out of her home in the court and coax Caliban into a good humour, and lead him indoors. The aged woman is Caliban's mother—she cannot be always looking after him, because she has to make cardboard boxes for a living.

Some day there will be a terrible crime committed in that court, or Caliban will wander away to do his deed, and there will be a shocking story in the newspapers. Then everyone will wonder why Caliban was not put in an asylum where he could be properly guarded and restrained. He is a monster, likely to commit a brutal crime at any moment. But as he has not, so far, done anything criminal, no one thinks it worth while to limit the bounds of his freedom.

Some of the mysterious crimes which baffle the police, because they can find no "motive" to give them a clue, are the deeds of homicidal maniacs at large. The crimes are often committed without provocation. The victim is unknown to them. The opportunity of killing occurs, and it is eagerly seized. Then the maniac, if he has escaped observation, goes quietly home, and thinks no more of his deed. In some cases he has no further knowledge of it.

I spent an afternoon in his private apartment at Broadmoor some time ago with a highly-cultured gentleman who left his chambers late one night, went out on to the Embankment, sat down on a seat on which a tramp was sleeping, and deliberately murdered the tramp. He shot him with a revolver. People hearing the shot ran up, and the murderer was arrested. But if he had throttled the man or stabbed him he would have gone quietly home again, and the murder would have remained a mystery.

When the prisoner was questioned the next day he had no recollection of what had occurred. He couldn't understand why he was detained. This unfortunate gentleman had a large circle of friends and acquaintances, many of whom had been his guests at the pleasant little dinner-parties he used to give in his luxurious chambers. None of them had the slightest suspicion that he was insane.

Nor would anyone suspect it who conversed with him to-day at Broadmoor. As a matter of fact, he is perfectly sane until midnight. But at midnight his entire nature changes, and he has to be approached with the greatest caution. From midnight till the break of day he is a maniac with a desire to kill. After that he is an amiable and cultured gentleman with whom it is a pleasure to associate.

One of the most charming men I ever met, a man so benevolent in appearance, so gentle in manner, that it seems to me even now impossible to think of him as a murderer, waited with a revolver night after night to kill a young fellow against whom he had an imaginary grievance. He succeeded at last. He shot his "enemy" dead at the corner of a street, and then walked quietly away. When he was seized he explained that he had only performed an act of justice, and he requested his captors to release him. He was anxious to get home at once, as he had friends coming to supper.
