when they came to the autopsy there wasn't a trace of poison of any kind. Of course the police wanted to know all about the people at Number 20, and here again, so I have heard from private sources, one or two other very curious points came out. It appears that the occupants of the house were a Mr. and Mrs. Charles Herbert; he was said to be a landed proprietor, though it struck most people that Paul Street was not exactly the place to look for county gentry. As for Mrs. Herbert, nobody seemed to know who or what she was, and, between ourselves, I fancy the divers after her history found themselves in rather strange waters. Of course they both denied knowing anything about the deceased, and in default of any evidence against them they were discharged. But some very odd things came out about them. Though it was between five and six in the morning when the dead man was removed, a large crowd had collected, and several of the neighbours ran to see what was going on. They were pretty free with their comments, by all accounts, and from these it appeared that Number 20 was in very bad odour in Paul Street. The detectives tried to trace down these rumours to some solid foundation of fact, but could not get hold of anything. People shook their heads and raised their eyebrows and thought the Herberts rather "queer," "would rather not be seen going into their house," and so on, but there was nothing tangible. The authorities were morally certain that the man met his death in some way or another in the house and was thrown out by the kitchen door, but they couldn't prove it, and the absence of any indications of violence or poisoning left them helpless. An odd case, wasn't it? But curiously enough, there's something more that I haven't told you. I happened to know one of the doctors who was consulted as to the cause of death, and some time after the inquest I met him, and asked him about it. "Do you really mean to tell me," I said, "that you were baffled by the case, that you actually don't know what the man died of?" "Pardon me," he replied, "I know perfectly well what caused death. Blank died of fright, of sheer, awful terror; I never saw features so hideously contorted in the entire course of my practice, and I have seen the faces of a whole host of dead." The doctor was usually a cool customer enough, and a certain vehemence in his manner struck me, but I couldn't get anything more out of him. I suppose the Treasury didn't see their way to prosecuting the Herberts for frightening a man to death; at any rate, nothing was done, and the case dropped out of men's minds. Do you happen to know anything of Herbert?' 'Well,' replied Villiers, 'he was an old college friend of mine.' 'You don't say so? Have you ever seen his wife?' 'No, I haven't. I have lost sight of Herbert for many years.'
