It Takes a Spy... (Secrets and Seduction #1) by Sheridan Jeane

This story is a comedy and farce. The heroine educates her fiance on her priorities after he has been accused of stealing her family jewels. She helps him escape the runners and then helps him solve the mystery of who stole the jewels. Their are parts that are really funny and in Regency, England can you imagine a nineteen and fifteen year old girl running around London with her fiance. Its a good story if you read it with the idea of a farce.
