Mistress

When a blackmailer threatens her Aunt Zoe, Iphiginia knows she can ferret out the villain. A 26-year-old vixen with the intellect to match her beauty, Iphiginia descends on London society as the dazzling mistress of the missing Earl of Masters—another supposed victim of the blackmailer. But when the missing earl suddenly reappears at a ball, Iphiginia is caught in her own clever lie.
