What Mad Universe

Pulp SF magazine editor Keith Winton was answering a letter from a teenage fan when the first moon rocket fell back to Earth and blew him away. But where to? Greenville, New York, looked the same, but Bems (Bug-Eyed Monsters) just like the ones on the cover of Startling Stories walked the streets without attracting undue comment. And when he brought out a half-dollar coin in a drugstore, the cops wanted to shoot him on sight as an Arcturian spy. Wait a minute. Seven-foot purple moon-monsters? Earth at war with Arcturus? General Dwight D. Eisenhower in command of Venus Sector? What mad universe was this? One thing was for sure: Keith Winton had to find out fast - or he'd be good and dead, in this universe or any other.
