Holmes looked round him with curiosity.

“But do you tell me that you never go out?” he said.

“Now and again I drive down to Sotheby’s or Christie‘s. Otherwise I very seldom leave my room. I am not too strong, and my researches are very absorbing. But you can imagine, Mr. Holmes, what a terrific shock — pleasant but terrific — it was for me when I heard of this unparalleled good fortune. It only needs one more Garrideb to complete the matter, and surely we can find one. I had a brother, but he is dead, and female relatives are disqualified. But there must surely be others in the world. I had heard that you handled strange cases, and that was why I sent to you. Of course, this American gentleman is quite right, and I should have taken his advice first, but I acted for the best.”

“I think you acted very wisely indeed,” said Holmes. “But are you really anxious to acquire an estate in America?”

“Certainly not, sir. Nothing would induce me to leave my collection. But this gentleman has assured me that he will buy me out as soon as we have established our claim. Five million dollars was the sum named. There are a dozen specimens in the market at the present moment which fill gaps in my collection, and which I am unable to purchase for want of a few hundred pounds. Just think what I could do with five million dollars. Why, I have the nucleus of a national collection. I shall be the Hans Sloane of my age.”

His eyes gleamed behind his great spectacles. It was very clear that no pains would be spared by Mr. Nathan Garrideb in finding a namesake.

“I merely called to make your acquaintance, and there is no reason why I should interrupt your studies,” said Holmes. “I prefer to establish personal touch with those with whom I do business. There are few questions I need ask, for I have your very clear narrative in my pocket, and I filled up the blanks when this American gentleman called. I understand that up to this week you were unaware of his existence.”

“That is so. He called last Tuesday.”

“Did he tell you of our interview to-day?”

“Yes, he came straight back to me. He had been very angry.”

“Why should he be angry?”

“He seemed to think it was some reflection on his honour. But he was quite cheerful again when he returned.”

“Did he suggest any course of action?”

“No, sir, he did not.”

“Has he had, or asked for, any money from you?”

“No, sir, never!”

“You see no possible object he has in view?”

“None, except what he states.”

“Did you tell him of our telephone appointment?”

“Yes, sir, I did.”

Holmes was lost in thought. I could see that he was puzzled.

“Have you any articles of great value in your collection?”

“No, sir. I am not a rich man. It is a good collection, but not a very valuable one.”
