"What are his symptoms?" asked Thorndyke.
"Oh, he thinks he is being followed about and watched, and he has delusions; sees himself in the glass with the wrong face, and that sort of thing, you know."
"You are not highly circumstantial," Thorndyke remarked.
Mr. Brodribb looked at me with a genial smile.
"What a glutton for facts this fellow is, Jervis. But you're right, Thorndyke; I'm vague. However, Fred will be here presently. We travel down together, and I took the liberty of asking him to call for me. We'll get him to tell you about his delusions, if you don't mind. He's not shy about them. And meanwhile I'll give you a few preliminary facts. The trouble began about a year ago. He was in a railway accident, and that knocked him all to pieces. Then he went for a voyage to recruit, and the ship broke her propeller-shaft in a storm and became helpless. That didn't improve the state of his nerves. Then he went down the Mediterranean, and after a month or two, back he came, no better than when he started. But here he is, I expect."
He went over to the door and admitted a tall, frail young man whom Thorndyke welcomed with quiet geniality, and settled in a chair by the fire. I looked curiously at our visitor. He was a typical neurotic—slender, fragile, eager. Wide-open blue eyes with broad pupils, in which I could plainly see the characteristic "hippus"—that incessant change of size that marks the unstable nervous equilibrium—parted lips, and wandering taper fingers, were as the stigmata of his disorder. He was of the stuff out of which prophets and devotees, martyrs, reformers, and third-rate poets are made.
"I have been telling Dr. Thorndyke about these nervous troubles of yours," said Mr. Brodribb presently. "I hope you don't mind. He is an old friend, you know, and he is very much interested."
"It is very good of him," said Calverley. Then he flushed deeply, and added: "But they are not really nervous, you know. They can't be merely subjective."
"You think they can't be?" said Thorndyke.
"No, I am sure they are not." He flushed again like a girl, and looked earnestly at Thorndyke with his big, dreamy eyes. "But you doctors," he said, "are so dreadfully sceptical of all spiritual phenomena. You are such materialists."
"Yes," said Mr. Brodribb; "the doctors are not hot on the supernatural, and that's the fact."
"Supposing you tell us about your experiences," said Thorndyke persuasively. "Give us a chance to believe, if we can't explain away."
Calverley reflected for a few moments; then, looking earnestly at Thorndyke, he said:
"Very well; if it won't bore you, I will. It is a curious story."
"I have told Dr. Thorndyke about your voyage and your trip down the Mediterranean," said Mr. Brodribb.
"Then," said Calverley, "I will begin with the events that are actually connected with these strange visitations. The first of these occurred in Marseilles. I was in a curio-shop there, looking over some Algerian and Moorish tilings, when my attention was attracted by a sort of charm or pendant that hung in a glass case. It was not particularly beautiful, but its appearance was quaint and curious, and took my fancy. It consisted of an oblong block of ebony in which was set a single pear-shaped pearl more than three-quarters of an inch long. The sides of the ebony block were lacquered—probably to conceal a joint—and bore a number of Chinese characters, and at the top was a little gold image with a hole through it, presumably for a string to suspend it by. Excepting for the pearl, the whole thing was uncommonly like one of those ornamental tablets of Chinese ink.
"Now, I had taken a fancy to the thing, and I can afford to indulge my fancies in moderation. The man wanted five pounds for it; he assured me that the pearl was a genuine one of fine quality, and obviously did not believe it himself. To me, however, it looked like a real pearl, and I determined to take the risk; so I paid the money, and he bowed me out with a smile—I may almost say a grin—of satisfaction. He would not have been so well pleased if he had followed me to a jeweller's to whom I took it for an expert opinion; for the jeweller pronounced the pearl to be undoubtedly genuine, and worth anything up to a thousand pounds.
"A day or two later, I happened to show my new purchase to some men whom I knew, who had dropped in at Marseilles in their yacht. They were highly amused at my having bought the thing, and when I told them what I had paid for it, they positively howled with derision.
"'Why, you silly guffin,' said one of them, a man named Halliwell, 'I could have had it ten days ago for half a sovereign, or probably five shillings. I wish now I had bought it; then I could have sold it to you.'
"It seemed that a sailor had been hawking the pendant round the harbour, and had been on board the yacht with it.
"'Deuced anxious the beggar was to get rid of it, too,' said Halliwell, grinning at the recollection. 'Swore it was a genuine pearl of priceless value, and was willing to deprive himself of it for the trifling sum of half a jimmy. But we'd heard that sort of thing before. However, the curio-man seems to have speculated on the chance of meeting with a greenhorn, and he seems to have pulled it off. Lucky curio man!'
"I listened patiently to their gibes, and when they had talked themselves out I told them about the jeweller. They were most frightfully sick; and when we had taken the pendant to a dealer in gems who happened to be staying in the town, and he had offered me five hundred pounds for it, their language wasn't fit for a divinity students' debating club. Naturally the story got noised abroad, and when I left, it was the talk of the place. The general opinion was that the sailor, who was traced to a tea-ship that had put into the harbour, had stolen it from some Chinese passenger; and no less than seventeen different Chinamen came forward to claim it as their stolen property.
"Soon after this I returned to England, and, as my nerves were still in a very shaky state, I came to live with my cousin Alfred, who has a large house at Weybridge. At this time he had a friend staying with him, a certain Captain Raggerton, and the two men appeared to be on very intimate terms. I did not take to Raggerton at all. He was a good-looking man, pleasant in his manners, and remarkably plausible. But the fact is—I am speaking in strict confidence, of course—he was a bad egg. He had been in the Guards, and I don't quite know why he left; but I do know that he played bridge and baccarat pretty heavily at several clubs, and that he had a reputation for being a rather uncomfortably lucky player. He did a good deal at the race-meetings, too, and was in general such an obvious undesirable that I could never understand my cousin's intimacy with him, though I must say that Alfred's habits had changed somewhat for the worse since I had left England.
"The fame of my purchase seems to have preceded me, for when, one day, I produced the pendant to show them, I found that they knew all about it. Raggerton had heard the story from a naval man, and I gathered vaguely that he had heard something that I had not, and that he did not care to tell me; for when my cousin and he talked about the pearl, which they did pretty often, certain significant looks passed between them, and certain veiled references were made which I could not fail to notice.
"One day I happened to be telling them of a curious incident that occurred on my way home. I had travelled to England on one of Holt's big China boats, not liking the crowd and bustle of the regular passenger-lines. Now, one afternoon, when we had been at sea a couple of days, I took a book down to my berth, intending to have a quiet read till tea-time. Soon, however, I dropped off into a doze, and must have remained asleep for over an hour. I awoke suddenly, and as I opened my eyes, I perceived that the door of the state-room was half-open, and a well-dressed Chinaman, in native costume, was looking in at me. He closed the door immediately, and I remained for a few moments paralyzed by the start that he had given me. Then I leaped from my bunk, opened the door, and looked out. But the
