An extraordinary woman living in extraordinary times, Lady Frances Ffolkes is an Edwardian era suffragette who has an uncanny ability to attract danger and romance. When Major Colcombe, a family friend and war veteran, dies under mysterious circumstances, the good Lady discovers that he was working on a manuscript, about South Africa's bloody Boer War, that reportedly revealed a scandalous mistake that cost many innocent lives.
Lady Frances Ffolkes is incensed when she finds out that her dear friends Gwendolyn and Thomasina have been subject to vicious threats. Promising to uncover their attacker, she travels with them to Kestrel's Eyrie, the fabled estate belonging to Gwen's family. But soon Frances faces an even greater problem, when Gwen's father, a powerful diplomat, is stabbed to death with his prized ruby dagger.
