"She can't. She knows no more of my real history

than you do; no more than I actually know of hers. Our knowledge of each other began when we started to 'pal' together; it ended when we split, eighteen months ago. But about this letter? What is it? Why do you say that you don't like it?"

"Well, to begin with, I'm afraid it is some trap of hers to decoy you over there, get you into some unknown place——"

"There are no 'unknown places' in Paris so far as I am concerned. I know every hole and corner of it, from the sewers on. I know it as well as I know London, as well as I know Berlin—New York—Vienna—Edinburgh—Rome. You couldn't lose me or trap me in any one of them. Is that the letter in your hand? Good—then read it, please."

Narkom, obeying the request, read:

"To the Superintendent of Police, Scotland Yard,

"Distinguished Monsieur:

"Of your grace and pity, I implore you to listen to the prayer of an unhappy man whose honour, whose reason, whose very life are in deadly peril, not alone of 'The Red Crawl,' but of things he may not even name, dare not commit to writing, lest this letter should go astray. It shall happen, monsieur, that the whole world shall hear with amazement of that most marvellous 'Cleek'—that great reader of riddles and unmasker of evildoers who, in the past year, has made the police department of England the envy of all nations; and it shall happen also that I who dare not appeal to the police of France appeal to the mercy, the humanity, of this great man, as it is my only hope. Monsieur, you have his ear, you have his confidence, you have the means at your command. Ah! ask him, pray him, implore him for the love of God, and the sake of a fellow-man, to come alone to the top floor of the house number 7 of the Rue Toison d'Or, Paris, at nine hours of the night of Friday, the 26th inst., to enter into the darkness and say but the one word 'Cleek' as a signal it is he, and I may come forward and throw myself upon his mercy. Oh, save me, Monsieur Cleek—save me! save me!

"There, that's the lot, and there's no signature," said Narkom, laying down the letter. "What do you make of it, Cleek?"
