gate. Now put yourself in that man's place. On thinking the matter over, it must have occurred to him that it was possible that he had lost the ring in the road after leaving the house. What would he do, then? He would eagerly look out for the evening papers in the hope of seeing it among the articles found. His eye, of course, would light upon this. He would be overjoyed. Why should he fear a trap? There would be no reason in his eyes why the finding of the ring should be connected with the murder. He would come. He will come. You shall see him within an hour?"
"And then?" I asked.
"Oh, you can leave me to deal with him then. Have you any arms?"
"I have my old service revolver and a few cartridges."
"You had better clean it and load it. He will be a desperate man, and though I shall take him unawares, it is as well to be ready for anything."
I went to my bedroom and followed his advice. When I returned with the pistol the table had been cleared, and Holmes was engaged in his favourite occupation of scraping upon his violin.
"The plot thickens," he said, as I entered; "I have just had an answer to my American telegram. My view of the case is the correct one."
"And that is?" I asked eagerly.
"My fiddle would be the better for new strings," he remarked. "Put your pistol in your pocket. When the fellow comes speak to him in an ordinary way. Leave the rest to me. Don't frighten him by looking at him too hard."
"It is eight o'clock now," I said, glancing at my watch.
"Yes. He will probably be here in a few minutes. Open the door slightly. That will do. Now put the key on the inside. Thank you! This is a queer old book I picked up at a stall yesterday—'De Jure inter Gentes'—published in Latin at Liege in the Lowlands, in 1642. Charles' head was still firm on his shoulders when this little brown-backed volume was struck off."
"Who is the printer?"
"Philippe de Croy, whoever he may have been. On the fly-leaf, in very faded ink, is written 'Ex libris Guliolmi Whyte.' I wonder who William Whyte was. Some pragmatical seventeenth century lawyer, I suppose. His writing has a legal twist about it. Here comes our man, I think."
As he spoke there was a sharp ring at the bell. Sherlock Holmes rose softly and moved his chair in the direction of the door. We heard the servant pass along the hall, and the sharp click of the latch as she opened it.
