“A few days ago,” pursued Thorndyke, “ Dr. Jervis and I located, with the aid of this chart, the house to which he had been called. We found that the late tenant had left somewhat hurriedly and that the house was to let; and, as no other kind of investigation was possible, we obtained the keys and made an exploration of the premises.”

Here he gave a brief account of our visit and the conditions that we observed, and was proceeding to furnish a list of the articles that we had found under the grate, when Mr. Winwood started from his chair.
