Lady Audley's Secret follows Robert Audley through his detective-like work in trying to uncover what happened to his friend George Talboys and who his uncle's wife, Lucy Audley, really is. During his search, Robert has to deal with lies, deceit, and even an attempt to kill him. Although the novel's content of bigamy and attempted murder was considered fairly immoral at the time of publication, it was extremely successful. It has been in print ever since its first publication.
