Larry Larkin is a Frogman during the Korean fighting. He is supersensitive to inter-service insult, prone to self accusations concerning his courage and nervously in love with Harriet Hunt, a Red Cross girl. His best friend is Lew Critchell, a member of Larry's Underwater Demolition Team. He is the object of Larry's jealousy over Harriet. When Larry gets a spot promotion to ensign, Lew is his chief problem. Does Lew's constant volunteering mean he is heroic? or a glory grabber? or a potential suicide? Or is Harriet at the bottom of it all? All this is moist, male melodrama that detracts from the real interest this title will hold for readers. Larry, Lew and their UDT unit face everything that a Frogman can encounter -- ""Sneak and peek"" jobs, wham and scram"" raids, sharks, enemy fire above and below water and submarine rescue. These are the scenes that the author does best. His fictional characters fail to come alive or grow up despite the dangers they survive and the loss of life around them.
