Showing Eden in Winter by Richard North Patterson

Two months after the suspicious and much-publicized death of his father on the island of Martha's Vineyard, it is taking all of Adam Blaine's character to suture the deep wounds - both within his family and himself - torn open by the tragedy. Moreover, as the court inquest into Benjamin Blaine's death continues, it is taking all of Adam's cunning to protect those closest to him from figures who still suspect that Adam's father was murdered by one of his kin. But the sternest test of all is Adam's proximity to Carla Pacelli - his late father's mistress; and a woman who, despite being pivotal to his family's plight, Adam finds himself increasingly drawn to. The closer he gets to this beautiful, mysterious woman, the further Adam feels from his troubles. Yet the closer he also comes to revealing the secrets he's strived to conceal, and condemning the people he's fought so hard to protect.
