That was an expression I'd heard and had taken the trouble to make certain I understood. It seemed to be just the thing in the present case. "I'd like that," Beth said. "Pick me up about nine." Her choice of time could not have been more suitable. I was out of money. There was Mrs. Mara to be paid, and now the cost of the evening's entertainment. Until darkness fell I could do nothing about that. So I went back to my room and read old newspapers I had collected. I had discovered on my first day that those were the best sources of information. Those and the moving pictures. For one who must learn a great deal about a people in a short time there is one infallible way: watch them in their favorite sports and relaxations. The moving pictures and the comic strips had been invaluable. In another few weeks I could have passed anywhere. At eight o'clock it was growing dark. I changed my shirt, put on a sport coat and left the room. Five minutes later I was walking down a quiet street that was lined with fashionable homes. After that it was merely a question of time. I went around the block, found that it was still too light, and went around again, this time slowly. There was only one man on the street on my next time around. I sized him up quickly and decided that he was prosperous. He came on toward me. I managed to be looking the other way. We bumped into each other and he fell. I said, "Sorry" and bent to help him up. My fingers touched his throat in the proper places and he went limp. Within a matter of seconds I had his wallet out of his pocket and extracted several bills. When his eyes flickered again I was just raising him to his feet. "All my fault," I said contritely. "Are you all right?" "Seem to be." He was gruff, but that was all. He didn't know that for a matter of seconds he had been unconscious. At nine o'clock I came up the walk to the Copperd home. This time the security agent was leaning against a tree, lighting a cigarette. I made certain that he saw my face clearly. One upstairs window showed a light, and the faint murmur of voices drifted down. That had to be Copperd's room. Then a porch light flashed on and Beth came out of the door. She was wearing a white dress and the overhead light seemed to create a golden halo above her head. I momentarily forgot about her father. * * * * * How much can a man learn in a few weeks? I had to be so very careful. Historical matters had to be avoided at all costs. Contemporary affairs were fine. Philosophy was best. Philosophy is always the best. Good and evil are present everywhere. They can be discussed in the vaguest terms. We discussed many things in vague terms. And yet there was a sense of intimacy which grew between us. It was hard for me to define, and after a while I gave up trying to discover what it was. I merely enjoyed it.
