Vincent knows he's not the most charming of the Moretti brothers. He prefers brooding to flirting, reading to talking, and he sure as hell isn't about to give into his mother's insistence that he 'settle down with a nice girl.' Luckily, Vincent's gig as one of the NYPD's top homicide detectives keeps him busy. As does his long-time partner, Jill Henley-a tough-as-nails cop with the face of an angel and smart mouth that makes Vincent crazy in all the worst ways.After six years of working the homicide beat with the tight-lipped Vincent Moretti, Jill figure she knows him better than anyone. Which is not at all. But when their most recent case points to a potential serial-killer situation, the higher-ups send them on a rare undercover mission to a place no NYPD officer dares go: the Upper Eastside. Now the bureau's most antagonistic set of partners is posing as Mr. and Mrs. Brooks of Park Avenue. Spending 24/7 in the suspect's territory brings them closer and closer to their killer ... and closer to each other. Soon Vincent and Jill are playing good cop/bad cop in and out of bed, and Jill's falling hard. But can she convince Vincent to give her a shot as partner in life, as well as at the bureau?
