"Who are you? Why do you conceal who you are?" Colter, who had as he talked been dreamily staring at the river, sprang quickly back to an attitude of attention. Every motion he made, every slightest movement of hand or eyelash or the corners of lips, was under a remorseless observation, that of a genius for reading human beings. "Who are you?" The question was repeated very quietly, but now it had the note of inexorable authority. It was asked on behalf of Sard, whose trusting face and figure made it on Shipman's lips, stern, uncompromising. Colter, his face flushing, rose. The man had changed in a deadly sort of way. His head from which he had removed the cap sunk suddenly forward as if his face could not look into that old enigma "Who am I?" The hair, swept back in its curious boy-like wave, was of vital copper under which Shipman noted a very few gray hairs which seemed curiously premature for the face opposite. The white skin, slightly freckled, had a youthful, good modeling; the face bones made it of pure English build. Shipman, puzzled, tried to analyze the curious look of sorrow and patient suffering on it. His gaze went to one or two very small scars as of smallpox. _One or two very small scars, as of smallpox!_ The lawyer stared at the white teeth showing under a mustached lip set to a gaunt look of bravery and mental struggle. "I beg your pardon," said the other, "I had forgotten--forgotten myself. You treated me like a friend, and I went along easily. Things came easily--I was remembering," Colter sat up, his hands working at his belt. "Things came to me, but," he shook his head, "you ask who I am." The man turned the old mask of suffering on his interlocutor and shook his head. If the thing was acting, it was prodigious acting. Shipman told himself that such acting had gotten Sard's soul away from her. It should not, however, have her entire! That face with its strange look of sorrow suddenly maddened the lawyer. He straightened. This mask must be torn off. This charlatan must be shown up. Now an old vulpine habit of the court-room came on the legal face.
