The novel is about The Hon. Bertie Cecil or Beauty of the Brigades. In financial distress because of his own profligacy and the loss of an important horse-race on which he has bet extensively, and falsely accused of forgery, but unable to defend himself against the charge without injuring the "honour" of a lady and also exposing his younger brother (the real culprit), Cecil fakes his own death and exiles himself to Algeria where he joins the Chasseurs d''Afrique, a regiment comprising soldiers from various countries, rather like the French Foreign Legion. After Cecil''s great childhood friend and the friend''s beautiful sister show up in Africa, and after a series of melodramatic self-sacrifices by Cecil and by the young girl Cigarette, a "child of the Army" who sacrifices her life saving Cecil from a firing squad, the main conflicts are resolved and the surviving characters return to England to fortune, title, and love.
