The shipyard murders

"The year is 1943. Japan has attacked Pearl Harbor and America is entangled in a violent war. Inspired by women factory workers, especially Rosie the Riveter, Helen Brooks--a divorced, single mother from California--finds work as a welder at the Oregon Shipbuilding Corporation. When a murdered man mysteriously falls from the ship, Helen catches sight of her friend, Charlotte, fleeing the scene, and Helen is immediately named a witness. Refusing to believe that Charlotte would kill anyone, Helen sets out to prove her innocence and uncover the real killer"--P. [4] of cover.
