In post-WWII Laos, Vietnamese communists secretly commence to infiltrate the kingdom. They are countered by four dedicated Lao 'moles' who try to thwart these aims. Gurkha Colonel Jason Rance is unwittingly dragged into a confrontation between one of the Lao moles and a Thai spy and the mole gives him a ring as a reward for saving his life. During his appointment in Laos as military attach , Rance becomes a target of the KGB and of the Vietnamese communists, and is sought by the remaining three Lao moles because of the ring in his possession. Rance's two Lao language instructors are nieces of the Lao king and London hopes that, by stealth, Rance might, through them, persuade the king delay his coronation no further in an effort to prevent the spread of communism southwards. Can the new military attach manage to do the seemingly impossible? Based on historical fact and the author's personal experience, Operation Stealth is the fourth in a series of books involving Gurkha military units that may be read in any order and includes Operation Black Rose, Operation Janus, Operation Blind Spot and Operation Four Rings. The author, JP Cross, a much revered retired Gurkha colonel, draws on real characters and events he witnessed across various theatres of war.
