Isabella Dandaneau arrives in London from New Orleans following her wayward cousin, Mignon, who was in search of her inheritance. Mignon and Isabella each inherited half a treasure map. Mignon refuses to work with her cousin; instead, she strikes out on her own only to be murdered at her new lover's house. Isabella wishes to strike an alliance with Mignon's lover and find the missing map. Having survived the War Between the States as a saboteur, Isabella is no stranger to danger.

When Barrett Stanbridge picked up Mignon at the theatre, he was only looking for a brief dalliance with no strings. After a sensual evening, he awakens to discover her bludgeoned to death. As the public clamors for an arrest, the police plan to pick up their only suspect, Barrett. Having been involved in a past messy scandal, which involved murder, Barrett realizes he is the perfect dupe. The alliance Isabella offers is his only solution.

Their partnership leads them into the path of ruthless killers, who will stop at nothing to secure the priceless treasure. Danger heightens the attraction between Isabella and Barrett but each is afraid to trust their feelings. Time is running out as the villains make a bold move, forcing Barrett and Isabella's hand.

Readers who adore strong and bold heroines will be more than satisfied with THE PERFECT DESIRE. Barrett, a secondary character in the first two Perfect novels, demanded a complicated and not-so-innocent woman, and Ms. LaFoy has blessed him with one.
