Queen of Diamonds - The House of Cards Trilogy, #3

All of London knows the story of the vanished Lady Charlotte Endicott and the handsome reward that will accompany her safe return. Scores of blond-haired, blue-eyed impostors have tried their luck at Jack Endicott's casino claiming to be the girl, only to be turned away-but Queenie Dennis just might be the one. Fate takes a turn when she returns to London posing as a dressmaker fresh from France. Queenie quickly becomes the talk of the town, catching the eye of the handsome Lord Harkness.
As her love for him grows, Queenie's lies begin to catch up with her. Will Harkness call her bluff, or does love hold the winning hand?
