London, 1812. The slaughter of eight young prostitues in a house of refuge near Covent Garden leaves only one survivor-and on witness: Hero Jarvis, reform-minded daughter of the Prince Regent's cousin, Lord Jarvis. When Jarvis quashes any official inquiry that might reveal his daughter's involvement, Hero launches an investigation of her own and turns to Sebastian St. Cyr, Viscount Devlin, for help.
