Once she was known as La Mariposa, Vienna's most seductive-and most dangerous-spy. Then betrayal sent Lucia Booth back to England, and a life of anonymity. Until the one man she never thought she'd see again shows up at her "gentlemen's club". But has virile spymaster Ronan St. Simon come for her secret-or for her? Part of Bronwyn Scott's Ladies of Impropriety series. Look for A Lady Risks All and A Lady Dares from Harlequin Historical.
