Holmes’s expression was as impassive as ever under the jeers of his antagonist, but his clenched hands betrayed his acute annoyance.

“I am going through your house,” said he.

“Are you, though!” cried Peters as a woman’s voice and heavy steps sounded in the passage. “We’ll soon see about that. This way, officers, if you please. These men have forced their way into my house, and I cannot get rid of them. Help me to put them out.”

A sergeant and a constable stood in the doorway. Holmes drew his card from his case.

“This is my name and address. This is my friend, Dr. Watson.”

“Bless you, sir, we know you very well,” said the sergeant, “but you can’t stay here without a warrant.”

“Of course not. I quite understand that.”

“Arrest him!” cried Peters.

“We know where to lay our hands on this gentleman if he is wanted,” said the sergeant majestically, “but you’ll have to go, Mr. Holmes.”

“Yes, Watson, we shall have to go.”

A minute later we were in the street once more. Holmes was as cool as ever, but I was hot with anger and humiliation. The sergeant had followed us.

“Sorry, Mr. Holmes, but that’s the law.”

“Exactly, Sergeant, you could not do otherwise.”

“I expect there was good reason for your presence there. If there is anything I can do —”

“It’s a missing lady, Sergeant, and we think she is in that house. I expect a warrant presently.”

“Then I’ll keep my eye on the parties, Mr. Holmes. If anything comes along, I will surely let you know.”

It was only nine o’clock, and we were off full cry upon the trail at once. First we drove to Brixton Workhouse Infirmary, where we found that it was indeed the truth that a charitable couple had called-some days before, that they had claimed an imbecile old woman as a former servant, and that they had obtained permission to take her away with them. No surprise was expressed at the news that she had since died.

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 farther 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.
