But he learned nothing by this. Perhaps there was a quiet, paternal manner visible at times on Sir Denton's part, but on Nurse Elisia's nothing but an intense look and a display of eagerness to grasp fully his instructions in regard to some dying creature whose life they were trying to save. Nothing more; and her bearing was the same to him, always calm and distant. If ever she was eager, it was in respect to a patient, and, his wishes carried out, she was either watching at some bedside or gliding patiently about the ward to smooth and turn a hot pillow here, gently move an aching head or injured limb there; and after many months Neil Elthorne found, to the disturbance of his mental balance, that he was constantly thinking of Nurse Elisia, while, save in connection with her duties and his instructions, she apparently never gave him a thought. All these memories came back to Neil Elthorne as he sat that night by his father's couch. They troubled and annoyed him, and he moved feverishly from time to time in his chair. "It is absurd," he said to himself. "One would think I was some romantic boy, ready to be attracted by the first beautiful face I see-- Yes; she is beautiful, after all, and that simple white cap and plain black dress only enhance instead of hiding it. And she is a lady, I am sure. But what does it mean? A nurse; devoting herself to all those repulsive cases as if she were seeking by self-denial and punishment to make a kind of atonement for something which has gone before. What can have gone before? Who is she? Why is she there?" His questioning thoughts became so unbearable that he rose from his seat, thrust off the soft slippers he was wearing, and began to pace the room.
