Kerr, planted before her, with his head dropped, looked, looked, looked, as if he gave silence leave to answer for him what it would. It answered with a hundred echoes ringing up to her from long corridors of conjecture, half-articulated words breathing of how extraordinary the answer must be that he did not dare to make. He looked her up and down carefully, impersonally, with that air he had of regarding a rare specimen, thoughtfully; as if he weighed such ephemeral substance as chance. "What will you take for it?" he said at last. She was silent. With a sick distrust it came to her that it was the very worst thing he could have said after that speaking silence. She stepped away from him. "This thing is not for sale." He stared at her with amazement; then threw back his head and laughed as if something had amused him above all tragedy. "You are an extraordinary creature," he said, "but really I must have it. I can't explain the why of it; only give the sapphire to me, and you'll never be sorry for having done that for me. Whatever happens, you may be sure I won't talk. Even if the thing comes out, you shan't be mixed up in it." He had come near her again, and the point of his long forefinger rested on her arm. She was motionless, overwhelmed with pure terror, with despair. He was smiling, but there was a desperate something about him, stronger than the common desire of possession, terrifying in its intensity. She looked behind her. The thick glass of the window was there, a glimpse of the empty street and the figure of a woman in a blowing green veil turning the corner. "Why not give it to me now," he urged, "since, of course, you can't keep it? I could have it now in spite of you." Everything in her sprang up in antagonism to meet him. "I know what you are," she cried, "but you shan't have it. You have no more right to it than I. You can't get it away from me, and I shan't give it to you." He had grown suddenly paler; his eyes were dancing, fastened upon her breast. His long hands closed and opened. She looked down, arrested at the sight of her hand clenched just where her breath was shortest, over the sapphire's hiding-place.
