Rough Justice by Claire Youmans

Some people in Salmon Bay, a quiet coastal town near Seattle, have no regrets when Glen Lowry is lost at sea. But four years later, when his sunken fishing boat turns up at the bottom of the harbor, foul play is suspected. Classy, ambitious Chief Deputy Prosecutor Janet Schilling immediately launches a murder investigation which produces several surprising suspects- one of them her own former lover Catherine Adams, now living a reclusive life in a lighthouse on Seal Rock Island. The author, herself an attorney and sailing aficionado, has crafted a facinating page-turner. Filled with the beauty and danger of the sea, and unexpected plot twists, Rough Justice poses an intriguing question: Is murder ever justified?
