“Then may I recommend that you return there and be on hand in case I should want you? I have no desire to encourage false hopes, but you may rest assured that all that can be done will be done for the safety of Lady Frances. I can say no more for the instant. I will leave you this card so that you may be able to keep in touch with us. Now, Watson, if you will pack your bag I will cable to Mrs. Hudson to make one of her best efforts for two hungry travellers at 7:30 to-morrow.”

A telegram was awaiting us when we reached our Baker Street rooms, which Holmes read with an exclamation of interest and threw across to me. “Jagged or torn,” was the message, and the place of origin, Baden.

“What is this?” I asked.

“It is everything,” Holmes answered. “You may remember my seemingly irrelevant question as to this clerical gentleman’s left ear. You did not answer it.”

“I had left Baden and could not inquire.”

“Exactly. For this reason I sent a duplicate to the manager of the Englischer Hof, whose answer lies here.”

“What does it show?”

“It shows, my dear Watson, that we are dealing with an exceptionally astute and dangerous man. The Rev. Dr. Shlessinger, missionary from South America, is none other than Holy Peters, one of the most unscrupulous rascals that Australia has ever evolved - and for a young country it has turned out some very finished types. His particular specialty is the beguiling of lonely ladies by playing upon their religious feelings, and his so-called wife, an Englishwoman named Fraser, is a worthy helpmate. The nature of his tactics suggested his identity to me, and this physical peculiarity - he was badly bitten in a saloon-fight at Adelaide in ’89 - confirmed my suspicion. This poor lady is in the hands of a most infernal couple, who will stick at nothing, Watson. That she is already dead is a very likely supposition. If not, she is undoubtedly in some sort of confinement and unable to write to Miss Dobney or her other friends. It is always possible that she never reached London, or that she has passed through it, but the former is improbable, as, with their system of registration, it is not easy for foreigners to play tricks with the Continental police; and the latter is also unlikely, as these rogues could not hope to find any other place where it would be as easy to keep a person under restraint. All my instincts tell me that she is in London, but as we have at present no possible means of telling where, we can only take the obvious steps, eat our dinner, and possess our souls in patience. Later in the evening I will stroll down and have a word with friend Lestrade at Scotland Yard.”

But neither the official police nor Holmes’s own small but very efficient organization sufficed to clear away the mystery. Amid the crowded millions of London the three persons we sought were as completely obliterated as if they had never lived. Advertisements were tried, and failed. Clues were followed, and led to nothing. Every criminal resort which Shlessinger might frequent was drawn in vain. His old associates were watched, but they kept clear of him. And then suddenly, after a week of helpless suspense there came a flash of light. A silver-and-brilliant pendant of old Spanish design had been pawned at Bovington’s, in Westminster Road. The pawner was a large, clean-shaven man of clerical appearance. His name and address were demonstrably false. The ear had escaped notice, but the description was surely that of Shlessinger.

Three times had our bearded friend from the Langham called for news - the third time within an hour of this fresh development. His clothes were getting looser on his great body. He seemed to be wilting away in his anxiety. “If you will only give me something to do!” was his constant wail. At last Holmes could oblige him.
