If a list could be prepared of the people against whom some lunatic at large has sworn to be revenged for a grievance which exists solely in the imagination of the aggressor, it would be a very alarming document. It would show the world that a large number of men and women who are dangerously insane are living unrestrained lives, mixing with their fellow-citizens without let or hindrance, and only waiting for the opportunity to attack a supposed enemy. Many of these people are looked upon by their acquaintances merely as cranks. After the Beck case I received hundreds of letters from people with a grievance; a large number of them were well written, and the addresses at the head of them showed that the writers were in a good position. In some of these letters there was a threat of what would happen if the "persecutor" was not compelled by the Press to abandon his course of conduct. Some of them contained an unmistakable hint that murder might be the result if the persecution were not stopped or the wrong redressed. And all these people, absolutely insane, were free from any sort of guardianship or control. Three of them called upon me. One came late at night. He rushed in directly the door was opened and walked into my study, the door of which was open, before the astonished servant could interfere. I saw at once what I had to deal with, and I listened with the greatest attention to the story my visitor had to tell. As he told it he worked himself up into a frenzy. His features became convulsed, and he struck my writing-table again and again with his clenched fist. I only got rid of him at last by recommending him to a firm of solicitors, who would take his case up and see that his enemy--a near relative--was legally restrained from conspiring with an oculist to put his eyes out. Only once before have I conversed with a man who declaimed with such insane violence against an imagined enemy. I felt safer then, for the interview took place at Broadmoor, and two stalwart keepers stood by while the poor maniac foamed and raved. A year after my visit to the Broadmoor patient--a gentleman whose case had excited a good deal of interest--there was a movement to obtain his release. His friends thought he was cured, and that it was quite safe for him to be restored to his family. Fortunately the authorities took a different view.
