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!
