"Tom!" Taking her cheek away from mine, Lucy looked me in the face. "Fell out?" "Yes." "While the train was moving?" I nodded. "How awful! She might have been hurt! What did you do?" "That's where my folly began. I did nothing." She continued to stare at me, evidently not comprehending. My task was getting more and more difficult. After all, I almost wished that I had not begun it. "It was all so sudden, and I was so bewildered that I lost my head." "Then don't you know what became of her?" "I did not know till the evening papers appeared. She was killed." "Killed!" Lucy's arms were still about my neck. I felt them give a convulsive twitch. "What did you do when you knew she was killed?" "Went with MacCulloch to dine. You see, it seems that the body was found on the line. They appear to have jumped to the conclusion that there has been murder done. It struck me that if I went and told my story the odds were that I should be arrested as her murderer. I had not the courage to face the situation, and so by way of a compromise I went with MacCulloch to dine." Lucy removed her arms from about my neck. She put her hand to her forehead as if perplexed. "Tell me, plainly, just what happened. How did she fall out? Was there a scuffle?" "In a sense there was. To prevent my leaving the carriage she took me by the shoulder. In trying to maintain her hold she got her back to the open door. She must have stepped backwards before either of us realised how near to the open door she really was, because, before I had the faintest suspicion of what had happened or was about to happen, she had disappeared." There was silence. I did not feel equal to meeting Lucy's eyes, but I felt they were on my face. At last she spoke. "I see. No wonder I saw that something had happened. No wonder that you found it difficult to tell me what it was." Rising to her feet, she went to the fireplace. Leaning her elbow on the mantelshelf, she stood in such a position that her face was turned away from me. "Is there any probability of their being able to connect the affair with you?" "Given certain conditions, there is an absolute certainty. To my shame be it said, that is really the reason why I went with MacCulloch to dine." Then I told her about the fellow who had been in the adjoining compartment. How he had forced himself upon me at Victoria; how he claimed to have overheard all that had taken place; how he had arrived at his own conclusions; how he had levied on me blackmail. Lucy listened quietly, putting a question now and then, but never looking at me all the time. "And am I to understand that this person believes that you committed murder, and is prepared to go into the witness-box and swear it?" It was not only the question, it was, more than anything, the way in which she asked it, which made me shiver. "The fellow is a scoundrel."
