Saigon (Killmaster novel)

Claire La Farge, widow of a French intelligence officer, lives in a large rice and tea plantation in North Vietnam.

She sends her trusted servant, Saito, to Saigon to place an advert in the personal column of the Times of Vietnam hoping to contact former colleagues of her husband who can decode the message.

Agent Nick Carter, in Saigon posing as a WHO medical observer, answers the ad on a hunch and learns of Dupre's involvement.

Dupre's daughter, Antoinette (Toni), has become a heroin addict under the influence of Lin Tong – a Chinese communist spy interested in finding out the truth about her father.

Carter heads for the La Farge plantation accompanied by Saito while Lin Tong contacts his communist guerilla allies to be on the lookout for a western agent.
