One of the enigmas of WWII was the fate of the USS Grunion, the submarine carrying a crew of 70 men that vanished without a trace in 1942. Stevens (The Voyage of the Catalpa) charts the Navy career of the subs skipper, Jim Abele, from his 1926 Annapolis graduation through to WWII. With Abele in command, the $6 million Grunion was launched on December 22, 1941, carrying the Navys new top-secret MK 14 torpedoes. Abele, other skippers, and even the Navy itself were unaware of the weapons most dangerous defect: a circular run that caused it to boomerang, striking the very sub that had fired it. When news of its disappearance arrived, the families of the Grunions crew experienced shock, denial, despair, yet in the decades that followed, Abeles sons were unable to unravel the mystery of the subs fate. A scrap of Japanese paper, sold in 1998 for $1 in a Denver antiques shop, was later posted on a military history Web site, eventually leading to the subs location and expeditions to find it at Kiska, Alaska. The families emotional reactions and the tapestry of happenstances involved in the discovery is suspenseful, while Stevenss speculative description of the subs plunge to the ocean floor makes for a chilling conclusion.
