It has been several years since I have read "Next of Kin," but I have recommended it to every reader I know, whether they are fans of science fiction or not. Unless I am mistaken the story was written in 1954, long before manned space travel, and it is obvious by the description of the spacecraft and the perceptions of space travel. This does not in any way detract form the story, but in some way adds a bit to the humor. John Leeming is the main character. He is assigned to a remote area in outer space to act in some type of diplomatic capacity. But he is visited by misfortune and crash-lands on an alien planet which happens to be at war. Leeming finds himself imprisoned and labeled a spy. The story is a slow read until this point (approximately one full third to half of the book), but then the plot takes off into a wildly hilarious sprint that becomes increasingly more ingenious until the finale. Leeming has absolutely nothing at his disposal to aid in escape except for a block of wood and some copper wire that he strips from his prison bed, visual and audible observations from his cell window, and the most important element of all: superstitious and incredibly gullible captors. Leeming sets out on a journey of wit that convinces his jailers that invisible beings are poised to trample them into nothingness at his beckoned call, and that their enemies are "nuts" (a term that takes on a whole new world of meaning once you read the story).
This book is what all science fiction humor should be. The closest I have found are from the stories of Terry Pratchet's "Disk World" and related series', and "The Hitchhiker's Guide to the Galaxy," although "Next of Kin" is far superior to them, at least as a stand-alone story. I HIGHLY recommend this story to any reader! It is thoroughly entertaining!
