Lady Ambition's Dilemma - The Scott-De Quincy Mysteries, #3

A dynasty is at stake. It seemed like a straightforward request-and Helena is used to her sister Blanche making demands on her time and fortune. But the most ambitious of her sisters reveals a dilemma that may wipe out the title she holds. When tragedy strikes, Helena must reprise her role as the Investigating Lady to save a nephew she doesn't even like. And what about her own future? The return of a hero from the past awakens old emotions and suggests new possibilities, while the revelation of the full extent of Armand Fortier's family secret poses a challenge Fortier himself thinks insurmountable.
Where will Cupid's arrows land? Join Helena as she contends with a potential scandal that's even bigger than the last one, gains new allies and an enemy with a most convincing argument, and learns a secret that may change the course of history.
