'One of the most hardened female villains whose devices and desires have ever blackened fiction' The Athenaeum reviewer of Armadale (1866) was only one of many contemporary critics horrified by Lydia Gwilt, the bigamist, husband-poisoner and laudanum addict whose intrigues spur the plot of this most sensational of Victorian 'sensation novels'. When Miss Gwilt flings herself from the first class deck of a Thames steamer her attempted suicide sets off events that lead to Allan Armadale inheriting Thorpe Ambrose in Norfolk, to romantic rivalries, espionage, counter-espionage and greedy plans for murder.
