The doctor was our next goal. He had been called in, had found the woman dying of pure senility, had actually seen her pass away, and had signed the certificate in due form. “I assure you that everything was perfectly normal and there was no room for foul play in the matter,” said he. Nothing in the house had struck him as suspicious save that for people of their class it was remarkable that they should have no servant. So far and no further went the doctor.

Finally we found our way to Scotland Yard. There had been difficulties of procedure in regard to the warrant. Some delay was inevitable. The magistrate’s signature might not be obtained until next morning. If Holmes would call about nine he could go down with Lestrade and see it acted upon. So ended the day, save that near midnight our friend, the sergeant, called to say that he had seen flickering lights here and there in the windows of the great dark house, but that no one had left it and none had entered. We could but pray for patience and wait for the morrow.
