She held a little electric lantern, much like his own, in her left hand, while with the other she turned over the leaves of a bundle of papers. An open drawer in the writing-table betrayed whence they had been taken; and she was so entirely engrossed in what she was about that the detective felt little fear of being noticed by her, concealed as he was in the outer darkness. He saw that she was short and slight, with a beautiful little head set gracefully upon her upright slender figure. Her expression was proud and self-contained, but the large dark eyes that glowed beneath long black lashes were in themselves striking evidence of a passionate nature sternly repressed, and an eloquent contradiction to the firm, tightly compressed lips. Here, thought Gimblet, was a nature which might pursue its object with cold and calculating tenacity, and then at the last moment let the prize slip through its fingers at some sudden call upon the emotions. For the time being her thoughts were evidently fixed upon her present purpose, to the exclusion of all considerations such as might have been expected to obtrude themselves upon the mind of a young girl engaged in a nocturnal raid. The dark solitude, the lateness of the hour, the surreptitious manner of her entry into the room, all these, which might well have occasioned some degree of nervousness in the coolest of housebreakers, appeared to produce, in her, nothing of the sort. As calmly as if she were sitting by her own bedside, she examined the documents in Lord Ashiel's bureau, sorting and folding the contents of one drawer after another as if it were the most commonplace thing in the world to go over other people's private papers in the dead of night. And what was she looking for? Gimblet felt no doubt on that subject. This could surely be no other than Julia, the adopted daughter of Countess Romaninov, whom Lord Ashiel had for so long supposed to be his daughter. In some way or other she must have discovered the problematic relationship, and now she was hunting for proof of her birth, or perhaps for the will which should deprive her of her inheritance. It was even possible that the dead peer had been mistaken, and that Julia was indeed his daughter and not unaware of the fact. But what was she doing here, and where did she come from? Surely Juliet had told him that all the guests had left the castle. Gimblet had never seen her before; but, as he watched her slow deliberate movements and quick intelligent eyes, he had an odd feeling that they were already acquainted. She reminded him of some one; how, he couldn't say. Perhaps it was the features, perhaps merely the expression, but if they had never previously met, at least he must have seen some one she resembled. Rack his brains as he might, he could not remember who it was. He put the thought aside. Sooner or later the recollection would come to him.
