When the scandalous Lord Blackstone returns to London, fashionable ladies cast inviting glances his way and his friends celebrate his infamous exploits. No one guesses that the lurid tales of his harem and the famous painting of his voluptuous mistress are a cover for an honorable promise and a secret mission to stop a deadly foreign agent.Only one woman remains unmoved by Blackstone's seductive ways. Banking heiress Violet Hammersley believes she has firm control over her passions and her life. That is, until her brother goes missing with a report vital to the British government--and the government puts Blackstone on the case. Now, if Violet wants to find her brother, she must work closely with the man who once broke her heart--without succumbing to the powerful impulse to fall for him again.
