Evidently he knew a good deal of Peter Zouche's methods, for I don't think his search lasted ten seconds. All at once his fingers closed over a tiny bag, something like a Catholic scapular, that had been slung around the hunchback's neck. With trembling fingers he tore this open, and disclosed to view the three precious manuscripts, which he instantly seized and packed away in his pocket. Then he made the bag look as natural as he could, and restored it to its position under the old man's singlet. As he rose to his feet again I saw that his face was ghastly white, and his teeth chattered like a man stricken with ague. "My God," he muttered, wiping the great beads of perspiration that had gathered about his temples, "isn't this chase stern--awful? I doubt if even I should have dared to have tried a terrible move like this had I not known that there, at St Bruno's at Hampstead, was the key to these documents awaiting me. But I felt I could not falter now when Camille Velasquon had braved so much in bringing it from Mexico to London for me. But, bah! what cowards we are all of us sometimes." And he reeled, and I am sure he would have fainted had I not instantly caught him myself and pressed the flask to his lips. "Now to be off--to be off," he said wildly a moment later, pushing me aside and staggering towards the exit from the tent. "I feel I can't breathe here now that I have got these documents. Every nerve I have seems standing on end urging me to be off." I turned to look at Doris lying so peacefully in that corner, and then, half distracted, turned to follow him, but as I did so somebody started up and confronted us. It was the Professor Stephen Leopardi! His aspect now was wild and threatening, but we thought merely that the terrible experiences he had been through above the clouds had temporarily disturbed the balance of his senses and that we could soothe him like a child. "You must not go," he panted, his eyes rolling and his fingers clawing the empty air. "You must stay with me, I want you. I have seen you. There is much to explain." "Quite so," I returned lightly, "but just now we are not in a mood for conversation, are we? Wait until our companions recover themselves and my friend and I have had a little fresh air, will you? Then we can all meet and discuss things, but at present--" "At present you would steal from that poor man the most precious things he has," thundered the old fellow, and to our horror he sprang between us and the exit and then pointed to the prostrate form of the hunchback. "Oh! never, never shall you escape like that." And before we realised what he was up to he raised his voice and shrieked: "Help! help! help!" CHAPTER SEVENTEEN. THE MYSTERIES OF ST BRUNO'S.
