"Her theory was a very wild one," he laughed. "Personally, I do not entertain it for one moment. The medical opinion that he died from a sudden but natural cause is undoubtedly correct," he said, replacing his dead cigar between his lips, as, slowly striking a vesta, he re-lit it. Then he added, "Her anxiety to avenge Dudley's death certainly seems to bear out your suspicion that they were lovers." "Then you entirely agree with me?" I cried. "In a measure only," he answered, his voice suddenly harsh and cold. "I have no suspicion that she ever reciprocated his affection, although in seeking to learn the truth of your friend's tragic end she must have had some very strong motive." "Another fact I also discovered was a trifle curious," I observed, after we had strolled along the deserted Terrace from end to end, discussing the details of Dudley's death, and the manner in which it had affected her. "What was it?" he inquired, glancing towards me. "I found that she was in the habit of visiting every day a pretty Russian girl with whom I was acquainted." "Before marriage?" he asked, raising his eyebrows meaningly. "Yes," I answered. "She was a refugee, and I had been enabled to render her father a service some time before; therefore we had become friends. I had lost sight of her for a long time, and when I again met her I discovered that she had not only been an intimate friend of poor Dudley, but that Ella visited her frequently on her bicycle when she was supposed by her mother to be riding in the Park." "Was there anything remarkable in that fact?" he inquired, with a half-amused air, nevertheless regarding me with undue keenness, I thought. "Nothing, except that the little Russian, who, having lost her father, was living a lonely life in a rather large house in Kensington, warned me against Ella, telling me she was my enemy. She, however, left without fulfilling her promise to reveal the details." "Your enemy!" he cried, laughing jocosely. "She was evidently jealous of your attentions to her, my boy. A Russian, too! She was a Nihilist, I suppose, or some interestingly romantic person of that sort, eh? Surely you didn't heed what she said, did you?" "Of course not," I replied, with a forced laugh. "I loved Ella too well; so I married her." "And you now regret it," he added abruptly. Without replying I walked on by his side, smoking furiously. My object in seeking him had been to learn what I could of Ella's past, but no mysterious incident had, to his knowledge, occurred. Her family were well-known in Yorkshire, respected throughout the county, and no breath of scandal had ever besmirched the fair fame of either Robert Laing's widow or his daughter. Beck, their intimate friend, concealed nothing from me, but frankly discussed my hopes and fears, expressing his heartfelt sympathy that I should have thus mysteriously lost my well-beloved, and offering me all the assistance that lay in his power.
