He had time to run over in his mind a dozen little speculations of who she was, ere she stirred; and at last, as if with change of purpose, he saw, or fancied that he saw, the door beginning slowly to close. Whether this was a mere trick of his excited imagination or not, a sudden gesture of impatience on his part threw down one of the cushions of the sofa. A slight shriek so slight as to be barely heard broke from the female, and she banged the door to. Norwood reached it with a spring; but although, as he wrenched it open, he could yet hear the rustling of a woman's dress in the passage, the sharp sound of a door hastily shut and locked defied all thought of pursuit, and he stood pondering over what had happened, and almost doubtful of its reality. “At least, the fair visitor belongs to the family; that much I may rely upon,” said he, as he lighted a candle to explore the locality a little closer. The corridor, however, abruptly stopped at a small door, which was locked on the inside; but to what portion of the house it led he could not even conjecture. He was not a very unlikely man to trace the clew of such an adventure as this seemed to be. It was one of those incidents with which his course of life had made him somewhat conversant; and few were better able to fill up from conjecture every blank of such a history. Nor was he one to shrink from any suspicion, no matter how repugnant to every thought of honor, nor how improbable to every mind less imbued with vice than his own. For a moment or two, however, he almost doubted whether the whole might not have been a dream, so sudden, so brief, so trackless did it all appear. This doubt, was, however, quickly resolved, as his eyes fell upon the floor, where a small fragment of a lace dress lay, as it was caught and torn off in the closing door. Norwood took it up, and sat down to examine it with attention. “Point d'Alencon,” said he, “bespeaks no vulgar wearer; and such is this! Who could have thought of George Onslow playing Lothario! But this comes of Italy. And now to find her out.” He ran over to himself half a dozen names, in which were nearly as many nationalities, but some doubt accompanied each. “No matter,” thought he, “the secret will keep.” He suddenly remembered, at the instant, that he had promised an acquaintance to pass some days with him in the Maremma, shooting; and, not sorry to have so good a reason for a few days' absence, he arose and set out towards his hotel, having first carefully placed within his pocketbook the little fragment of lace, a clew to a mystery he was resolved to explore hereafter.
