Bigamy, child abandonment, deception, theft, murder, and insanity all take part in Mary Elizabeth Braddon's novel. Her over-the-top drama was one of the most popular novels of the mid-1800s and provides an interesting portrayal of both class and gender issues as they intersect within the domestic sphere.

Lady Audley's Secret was one of the first and most successful sensation novels of the late 19th century. A young gentleman of leisure, Robert Audley, is spurred into action when his friend George Talboys goes missing from Audley Court. As an amateur detective, Robert travels the length and breadth of the country, only to discover that the answer to the mystery lies in the true identity of his uncle's wife, Lady Audley. True to its genre, the novel brings danger home to the private sphere of the country house and questions the unassailable boundaries of class. It is also a strident feminine criticism of the times, though debate still rages as to whether Braddon tidies her questions away too neatly at the end of the novel.

When beautiful young Lucy Graham accepts the hand of Sir Michael Audley, her fortune and her future look secure. But Lady Audley's past is shrouded in mystery, and Sir Michael's nephew Robert has vague forebodings. When Robert's good friend George Talboys suddenly disappears, he is determined to find him, and to unearth the truth. His quest reveals a tangled story of lies and deception, crime and intrigue, whose sensational twists turn the conventional picture of Victorian womanhood on its head. Can Robert's darkest suspicions really be true?
