Beau Geste

Beau Geste is a 1924 adventure novel by P. C. Wren. It has been adapted for the screen several times.

Michael "Beau" Geste is the protagonist. The main narrator (among others), by contrast, is his younger brother John. The three Geste brothers of Brandon Abbas are used as a metaphor for the British upper class values of a time gone by, and "the decent thing to do" is, in fact, the leitmotif of the novel.
