Confidence Game By JIM HARMON Illustrated by EPSTEIN [Transcriber's Note: This etext was produced from Galaxy Science Fiction June 1957. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] I admit it: I didn't know if I was coming or going—but I know that if I stuck to the old man, I was a comer ... even if he was a goner! Doc had this solemn human by the throat when I caught up with him. The golden Moon and the silver ship, symbols of greed. "Sure," the man agreed severely, prying a little worriedly at Doc's arthritic fingers that were clamped on his collar. "No argument. I came alongside and carefully started to lever the old man loose, one finger at a time. If a half dozen winos in Seattle hadn't helped me get them loose, Doc and I would have been wanted for the murder of a North American Mountie. It was easier this night and that made me afraid.

"He's my father and very old, as you can see." "'Memory Jump,' you mean. All my great-grandfathers have it. But Great-great-grandmother Lupos, funny thing, is like a schoolgirl. Sharp, you know. I told the human no, thanks, and walked Doc toward the flophouse three doors down. I didn't know what would happen if we didn't. Doc was liable to say something that might nova Sol, for all I knew. Martians approaching the corner were sensing at Doc and me. They weren't men like Doc and me. It had happened a few times right after I first found him, but now it was worse. I tried not to think about it and helped Doc through the fly-specked flophouse doors.
