“Then without it.” With a quick movement Holmes pushed the fellow to one side and passed into the hall. A door half opened stood immediately before us. We entered. It was the dining-room. On the table, under a half-lit chandelier, the coffin was lying. Holmes turned up the gas and raised the lid. Deep down in the recesses of the coffin lay an emaciated figure. The glare from the lights above beat down upon an aged and withered face. By no possible process of cruelty, starvation, or disease could this wornout wreck be the still beautiful Lady Frances. Holmes’s face showed his amazement, and also his relief.

“Thank God!” he muttered. “It’s someone else.”

“Ah, you’ve blundered badly for once, Mr. Sherlock Holmes,” said Peters, who had followed us into the room.

“Who is this dead woman?”

“Well, if you really must know, she is an old nurse of my wife’s, Rose Spender by name, whom we found in the Brixton Workhouse Infirmary. We brought her round here, called in Dr. Horsom, of 13 Firbank Villas - mind you take the address, Mr. Holmes - and had her carefully tended, as Christian folk should. On the third day she died - certificate says senile decay - but that’s only the doctor’s opinion, and of course you know better. We ordered her funeral to be carried out by Stimson and Co., of the Kennington Road, who will bury her at eight o’clock to-morrow morning. Can you pick any hole in that, Mr. Holmes? You’ve made a silly blunder, and you may as well own up to it. I’d give something for a photograph of your gaping, staring face when you pulled aside that lid expecting to see the Lady Frances Carfax and only found a poor old woman of ninety.”

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.
