The Fifth-Dimension Catapult the story of Tommy Reames' extraordinary rescue of Professor Denham and his daughter-marooned in the fifth dimension. This is the prequel to Leinster's The Fifth-Dimension Tube. Murray Leinster, called the dean of modern science-fiction, was writing amazing super-science adventures in the early twenties before there ever was such a thing. His short stories, novelettes, and serial novels have appeared in most of the major American magazines, both slick and pulp, and many have been reprinted all over the world. He has made a distinguished name for himself in the fields of adventure, historical, western, sea, and suspense stories.
