All seems well and good when young Lucy Graham marries Sir Michael Audley; she has married well and Sir Michael is thoroughly devoted to his new bride. His daughter Alicia, however, sees
through her new stepmother’s girlish ways. Shortly after the wedding, Sir Michael’s nephew, the attractive but lazy barrister Robert Audley, welcomes back to England an old friend of his,
George Talboys. The pair visit the Audley Court, where George disappears in mysterious circumstances. Robert Audley is spurred into action, taking up the case of his missing friend with a
newfound passion and energy. Like the best detective novels, and with some wonderful melodrama, the plot unravels at great pace until the truth is revealed about Lady Audley’s Secret.
