In book 3 of the series Tom Swift Jr adventures, Tom the boy inventor, uses his fantastic jetmarine, a submarine with an Atom-powered jet propulsion system. Hey, it was the fifties, skill with fisticuffs, and much authorial convenience to catch a group of dastardly pirates who hijack vessels with an airplane-mounted pseudo-scientific knock-out gun.
This book is in great shape with no rips, writing or tears. The original dust jacket shows wear.
