HMA Destroyer Jackal had borne plenty of trouble - in the way of shot, bombs and torpedoes. But all that was from the outside. Now she was threatened insidiously from the inside. The new officer, lean and hard and handsome, met Lieutenant Hurst's wife; in Matheson's words: Used to be a model. Pretty as a picture and a top-flight bitch. Storm Warning! For Hurst was the ship's asdic specialist officer, a man of grave importance; a man who could not afford the worry of what was happening between the new officer and his wife..neither could the ship.
