"Ten minutes before your carriage rattled up I had another weird experience. Explain it if you can--I can't. I was seated at this very table poring over one of those precious manuscripts, which I hide in a place practically inaccessible to anybody except myself, when I became conscious I was not alone. Somebody, I felt certain, had come mysteriously on the scene and was watching me intently. I glanced up suddenly, and found there, at that small casement window which opens on the street, and which is usually guarded by the shutter you now see placed in position, the face of a man. `What do you want?' I cried angrily, and darted across the room to fling the shutter back into position with all the force I could exert. But he was much too swift for me. With incredible rapidity he flung an envelope through the opening and darted off, and the shutter and window slammed together, as I intended, but with an empty bang. The scoundrel had escaped! "Well, by that time I was accustomed to surprises, and so I took up the envelope, which was of a cheap, inferior make, similar to those sold by small stationers in poor districts. It had no address upon it, but it was sealed. I tore it open, and found inside a piece of paper bearing this message." After fumbling behind an ornament on the mantelpiece he produced a slip that had been evidently torn out of some child's exercise book, and upon which was written in feigned handwriting to resemble a schoolboy's: "Your secret is known. At the right moment I shall come to you and claim it for its lawful owner. Meanwhile, breathe not a word to a soul as you value your property and your life." "Of course," added the hunchback, with a shrug of the shoulders, "all this sounds the merest melodrama, and so it may be. But you and I know quite enough of the importance of those manuscripts to understand how many rich and extraordinary personages in England, in Spain, in Mexico have the keenest interest in their contents, their recovery, and their translation. Your Lord Cyril Cuthbertson, for one," shot out Zouche, glancing at the millionaire with eyes full of meaning, yet bright with the springs of his own hidden resentment. The Member of Parliament bit his lip. "Maybe, maybe," he said, but I could see the shot went home and that inwardly he was much perturbed. "Still, you must do your best, that's all. Personally, I should say it is your friend, Lord Fotheringay, who feels he can't trust you, but, really, it is your lookout. Come along, Glynn." And he led the way impatiently down the passage, and, before the dwarf could say another word, he had hurried me out into Tufton Street, which seemed still to be as deserted as the grave. As we stepped out we heard the door close behind us; and, remembering the mysterious letter which Don Jose had instructed me to hand to Lord Cuthbertson in the case of certain eventualities, I resolved on a bold step of my own.
