This describes the boomerang effect of a secret mission which captured almost intact a Japanese destroyer, and after refitting by the Seabees used it to spy on the Japanese operations in the Gilbert Islands just before the U. S. invasion of the Makin Atoll in 1943. It is so accurate in description of operations that no fiction book could have been made under the censorship at that time. This review is from a Seabee who served in the Pacific from 1943 to 1945, C.F.Rasmussen
