Impoverished Lady Viola and her twin brother David Northcombe find that their fortunes change dramatically when their entrepreneurial father dies unexpectedly, leaving them a vast fortune that will change their lives forever. Returning home to England, still reeling from their dramatic change in circumstances, fate seems to have smiled on them when the handsome, but impoverished, Duke of Glentorran dramatically rescues them from the perils of the sea.
Loyal to his family and friends, the Duke has little left but his pride and his determination to live up to his responsibilities. Eager to be loved for herself and keen to test rumors that the Duke is nothing more than a fortune hunter, Viola begs her brother to keep their inheritance secret.
Amongst the faded glories of the Glentorran Castle estate it seems that love is in the air as David finds himself falling for Meg, the Duke's shy and pretty sister. As they grow closer his loyalties become increasingly divided. Should he keep his newly found wealth a secret from the woman he loves, to please his sister? Or should he risk damaging Viola's budding relationship with the Duke by telling the truth?
