Some hours later Cyril, in his great four-posted bed, lay watching, with wide-open eyes, the fantastic shadows thrown by the dancing firelight on the panelled walls. To woo sleep was evidently not his intention, for from time to time he lighted a wax vesta and consulted the watch he held in his hand. At last the hour seemed to satisfy him, for he got out of bed and made a hasty toilet. Having accomplished this as best he could in the semi-obscurity, he slipped a pistol into his pocket and left his room.
Groping his way through the darkness, he descended the stairs and cautiously traversed the hall. Not a sound did he make. His stockinged feet moved noiselessly over the heavy carpet. At the door of the library he paused a moment and listened intently; then, pistol in hand, he threw open the door. Darkness and silence alone confronted him. Closing the door behind him, he lighted a match and carefully inspected the desk. Having assured himself that no fresh marks had appeared on its polished surface, he blew out the match and ensconced himself as comfortably as the limited space permitted behind the curtains of one of the windows. There he waited patiently for what seemed to him an eternity. He had just begun to fear that his vigil would prove fruitless, when his ear was gladdened by a slight sound. A moment later the light was switched on. Hardly daring to breathe, Cyril peered through the curtains. Valdriguez! Cyril's heart gave a bound of exultation. Had he not guessed that those marks could only have been made by her small, bony fingers?
Clad like a nun in a loose, black garment, which fell in straight, austere folds to her feet; a black shawl, thrown over her head, casting strange shadows on her pale, haggard face, she advanced slowly, almost majestically, into the room. Cyril had to acknowledge that she looked more like a medieval saint than a midnight marauder.
Evidently the woman had no fear of detection, for she never even cast one suspicious glance around her; nor did she appear to feel that there was any necessity for haste, for she lingered for some time near the writing-table, gazing at it, as if it had a fascination for her; but, finally, she turned away with a hopeless sigh and directed her attention to the bookcase. This she proceeded to examine in the most methodical manner. Book after book was taken down, shaken, and the binding carefully scrutinised. Having cleared a shelf, she drew a tape measure from her pocket and rapped and measured the back and sides of the case itself.
