"We have him! We have him!" he cried.

He was incoherent in his agitation. Holmes soothed him with a few words and thrust him into an armchair.

"Come, now, give us the order of events," said he.

"She came only an hour ago. It was the wife, this time, but the pendant she brought was the fellow of the other. She is a tall, pale woman, with ferret eyes."

"That is the lady," said Holmes.

"She left the office and I followed her. She walked up the Kennington Road, and I kept behind her. Presently she went into a shop. Mr.

Holmes, it was an undertaker's."

My companion started. "Well?" he asked in that vibrant voice which told of the fiery soul behind the cold gray face.

"She was talking to the woman behind the counter. I entered as well.

'It is late,' I heard her say, or words to that effect. The woman was excusing herself. 'It should be there before now,' she answered. 'It took longer, being out of the ordinary.' They both stopped and looked at me, so I asked some questions and then left the shop."

"You did excellently well. What happened next?"

"The woman came out, but I had hid myself in a doorway. Her suspicions had been aroused, I think, for she looked round her. Then she called a cab and got in. I was lucky enough to get another and so to follow her. She got down at last at No. 36, Poultney Square, Brixton. I drove past, left my cab at the corner of the square, and watched the house."

"Did you see anyone?"

"The windows were all in darkness save one on the lower floor. The blind was down, and I could not see in. I was standing there, wondering what I should do next, when a covered van drove up with two men in it. They descended, took something out of the van, and carried it up the steps to the hall door. Mr. Holmes, it was a coffin."

"Ah!"

"For an instant I was on the point of rushing in. The door had been opened to admit the men and their burden. It was the woman who had opened it. But as I stood there she caught a glimpse of me, and I think that she recognized me. I saw her start, and she hastily closed the door. I remembered my promise to you, and here I am."

"You have done excellent work," said Holmes, scribbling a few words upon a half-sheet of paper. "We can do nothing legal without a warrant, and you can serve the cause best by taking this note down to the authorities and getting one. There may be some difficulty, but I should think that the sale of the jewellery should be sufficient.

Lestrade will see to all details."

"But they may murder her in the meanwhile. What could the coffin mean, and for whom could it be but for her?"

"We will do all that can be done, Mr. Green. Not a moment will be lost. Leave it in our hands. Now Watson," he added as our client hurried away, "he will set the regular forces on the move. We are, as usual, the irregulars, and we must take our own line of action. The situation strikes me as so desperate that the most extreme measures are justified. Not a moment is to be lost in getting to Poultney Square.

"Let us try to reconstruct the situation," said he as we drove swiftly past the Houses of Parliament and over Westminster Bridge. "These villains have coaxed this unhappy lady to London, after first alienating her from her faithful maid. If she has written any letters they have been intercepted. Through some confederate they have engaged a furnished house. Once inside it, they have made her a prisoner, and they have become possessed of the valuable jewellery which has been their object from the first. Already they have begun to sell part of it, which seems safe enough to them, since they have no reason to think that anyone is interested in the lady's fate. When she is released she will, of course, denounce them. Therefore, she must not be released.

But they cannot keep her under lock and key forever. So murder is their only solution."

"That seems very clear."

"Now we will take another line of reasoning. When you follow two separate chains of thought, Watson, you will find some point of intersection which should approximate to the truth. We will start now, not from the lady but from the coffin and argue backward. That incident proves, I fear, beyond all doubt that the lady is dead. It points also to an orthodox burial with proper accompaniment of medical certificate and official sanction. Had the lady been obviously murdered, they would have buried her in a hole in the back garden. But here all is open and regular. What does this mean? Surely that they have done her to death in some way which has deceived the doctor and simulated a natural end--poisoning, perhaps. And yet how strange that they should ever let a doctor approach her unless he were a confederate, which is hardly a credible proposition."

"Could they have forged a medical certificate?"

"Dangerous, Watson, very dangerous. No, I hardly see them doing that.

Pull up, cabby! This is evidently the undertaker's, for we have just pa.s.sed the p.a.w.nbroker's. Would you go in, Watson? Your appearance inspires confidence. Ask what hour the Poultney Square funeral takes place to-morrow."

The woman in the shop answered me without hesitation that it was to be at eight o'clock in the morning. "You see, Watson, no mystery; everything above-board! In some way the legal forms have undoubtedly been complied with, and they think that they have little to fear.

Well, there's nothing for it now but a direct frontal attack. Are you armed?"

"My stick!"

"Well, well, we shall be strong enough. 'Thrice is he armed who hath his quarrel just.' We simply can't afford to wait for the police or to keep within the four corners of the law. You can drive off, cabby.

Now, Watson, we'll just take our luck together, as we have occasionally in the past."

He had rung loudly at the door of a great dark house in the centre of Poultney Square. It was opened immediately, and the figure of a tall woman was outlined against the dim-lit hall.

"Well, what do you want?" she asked sharply, peering at us through the darkness.

"I want to speak to Dr. Shlessinger," said Holmes.

"There is no such person here," she answered, and tried to close the door, but Holmes had jammed it with his foot.

"Well, I want to see the man who lives here, whatever he may call himself," said Holmes firmly.

She hesitated. Then she threw open the door. "Well, come in!" said she. "My husband is not afraid to face any man in the world." She closed the door behind us and showed us into a sitting-room on the right side of the hall, turning up the gas as she left us. "Mr. Peters will be with you in an instant," she said.

Her words were literally true, for we had hardly time to look around the dusty and moth-eaten apartment in which we found ourselves before the door opened and a big, clean-shaven bald-headed man stepped lightly into the room. He had a large red face, with pendulous cheeks, and a general air of superficial benevolence which was marred by a cruel, vicious mouth.

"There is surely some mistake here, gentlemen," he said in an unctuous, make-everything-easy voice. "I fancy that you have been misdirected.

Possibly if you tried farther down the street--"

"That will do; we have no time to waste," said my companion firmly.

"You are Henry Peters, of Adelaide, late the Rev. Dr. Shlessinger, of Baden and South America. I am as sure of that as that my own name is Sherlock Holmes."

Peters, as I will now call him, started and stared hard at his formidable pursuer. "I guess your name does not frighten me, Mr.

Holmes," said he coolly. "When a man's conscience is easy you can't rattle him. What is your business in my house?"

"I want to know what you have done with the Lady Frances Carfax, whom you brought away with you from Baden."

"I'd be very glad if you could tell me where that lady may be," Peters answered coolly. "I've a bill against her for nearly a hundred pounds, and nothing to show for it but a couple of trumpery pendants that the dealer would hardly look at. She attached herself to Mrs.

Peters and me at Baden--it is a fact that I was using another name at the time--and she stuck on to us until we came to London. I paid her bill and her ticket. Once in London, she gave us the slip, and, as I say, left these out-of-date jewels to pay her bills. You find her, Mr.

Holmes, and I'm your debtor."

"I MEAN to find her," said Sherlock Holmes. "I'm going through this house till I do find her."

"Where is your warrant?"

Holmes half drew a revolver from his pocket. "This will have to serve till a better one comes."

"Why, you're a common burglar."

"So you might describe me," said Holmes cheerfully. "My companion is also a dangerous ruffian. And together we are going through your house."

Our opponent opened the door.

"Fetch a policeman, Annie!" said he. There was a whisk of feminine skirts down the pa.s.sage, and the hall door was opened and shut.
