Beau Geste is an adventure novel by British writer P. C. Wren, which details the adventures of three English brothers who enlist separately in the French Foreign Legion following the theft of a valuable jewel from the country house of a relative. Published in 1924, the novel is set in the period before World War I. It has been adapted for the screen several times. Plot summary Michael "Beau" Geste is the protagonist. The main narrator is his younger brother John. The three Geste brothers are portrayed as behaving according to the English upper-class values of a time gone by. The Geste siblings are orphans and have been brought up by their aunt Lady Patricia at Brandon Abbas. The rest of Beau's band are mainly Isobel and Claudia (possibly the illegitimate daughter of Lady Patricia) and Lady Patricia's relative Augustus (the caddish nephew of the absent Sir Hector Brandon).

The commander at Fort Zinderneuf (after the death of two more senior officers) is the sadistic Sergeant Major Lejaune, who drives his abused subordinates to the verge of mutiny. An attack by Tuaregs prevents mutiny and mass desertion (only the Geste brothers and a few loyalists are against the plot). Throughout the book, Beau's behaviour is true to France and the Legion, and he dies at his post. Digby, Hank and Buddy arrive with a relief column from Tokotu that reaches Fort Zinderneuf too late. Together with John (the
