skirts a little, she strode past Jack and Mary. Martin Kesserich followed her. In passing, he said, "Thanks, Barr." It occurred to Jack that Kesserich made no more question of his appearance on the island than of his presence in the laboratory. Like Mrs. Kesserich, the great biologist took him for granted. Kesserich stopped a few feet short of Hani and Hilda. Without shrinking from him, the sisters drew closer together. They looked like two gaunt hawks. "But you waited eighteen years," he said. "You could have killed her at any time, yet you chose to throw away so much of your lives just to have this moment." "How do you know we didn't like waiting eighteen years?" Hani answered him. "Why shouldn't we want to make as strong an impression on you as anyone? And as for throwing our lives away, that was your doing. Oh, Martin, you'll never know anything about how your sisters feel!" He raised his hands baffledly. "Even assuming that you hate me—" at the word "hate" both Hani and Hilda laughed softly—"and that you were prepared to strike at both my love and my work, still, that you should have waited...." Hani and Hilda said nothing. Kesserich shrugged. "Very well," he said in a voice that had lost all its tension. "You've wasted a third of a lifetime looking forward to an irrational revenge. And you've failed. That should be sufficient punishment." Very slowly, he turned around and for the first time looked at Mary. His face was clearly revealed by the twin beams from the stalled car. Jack grew cold. He fought against accepting the feelings of wonder, of poignant triumph, of love, of renewed youth he saw entering the face in the headlights. But most of all he fought against the sense that Martin Kesserich was successfully drawing them all back into the past, to 1933 and another accident. There was a distant hoot and Jack shook. For a moment he had thought it a railway whistle and not a ship's horn. The biologist said tenderly, "Come, Mary." Jack's trembling arm tightened a trifle on Mary's waist. He could feel her trembling. "Come, Mary," Kesserich repeated. Still she didn't reply.
