Murder visits a seaside mansion in this gothic mystery from the #1 New York Times–bestselling author known as the American Agatha Christie.
 The house called Sunset has been Marcia’s summer home for her entire life. Both of her parents died there, and she and her brother spent their youth exploring its rambling hallways and seaside grounds. They love the old house, but Marcia’s sister-in-law has never taken to it. Juliette loathes the sea, and soon comes to loathe her husband, as well. After they divorce, Juliette pays a final visit to Sunset, demanding alimony. She is there for a few tense days before she disappears. It takes them a week to find her body.
The peace at Sunset has been shattered, and Marcia must work quickly to keep her beloved childhood home from being forever spoiled. Somewhere in the creaky old mansion, a murderer lurks. Will Marcia be accused of the crime? Or will she be the next victim?
