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. Jack wet his lips. "Mary isn't going with you, Professor," he said. "Quiet, Barr," Kesserich ordered absently. "Mary, it is necessary that you and I leave the island at once. Please come." "But Mary isn't coming," Jack repeated. Kesserich looked at him for the first time. "I'm grateful to you for the unusual sense of loyalty--or whatever motive it may have been--that led you to follow me out here tonight. And of course I'm profoundly grateful to you for saving Mary's life. But I must ask you not to interfere further in a matter which you can't possibly understand." He turned to Mary. "I know how shocked and frightened you must feel. Living two lives and then having to face two deaths--it must be more terrible than anyone can realize. I expected this meeting to take place under very different circumstances. I wanted to explain everything to you very naturally and gently, like the messages I've sent you every day of your second life. Unfortunately, that can't be. "You and I must leave the island right now." Mary stared at him, then turned wonderingly toward Jack, who felt his heart begin to pound warmly. "You still don't understand what I'm trying to tell you, Professor," he said, boldly now. "Mary is not going with you. You've deceived her all her life. You've taken a fantastic amount of pains to bring her up under the delusion that she is Mary Alice Pope, who died in--" "She _is_ Mary Alice Pope," Kesserich thundered at him. He advanced toward them swiftly. "Mary darling, you're confused, but you must realize who you are and who I am and the relationship between us." "Keep away," Jack warned, swinging Mary half behind him. "Mary doesn't love you. She can't marry you, at any rate. How could she, when you're her father?" "Barr!" "Keep off!" Jack shot out the flat of his hand and Kesserich went staggering backward. "I've talked with your wife--your wife on the mainland. She told me the whole thing." * * * * *
