The Perfect Sister

I love the kind of us-and-them stories set in places like the Hamptons, and the latest by DeCarolis (The Guilty Husband, Deadly Little Lies) is packed with twists. Alex and Maddie Walker are sisters who look so alike and are so close in age that people think they’re twins. Their mother referred to them that way, a glimpse of love amid her boozy, selfish ways. Now Mom’s long gone, and the sisters, who are now in their twenties, are distant after an argument that followed her funeral. But when Alex doesn’t hear from Maddie, who has been in the Hamptons for the summer, she heads to that tony town to get to the bottom of things. What she finds is very strange—Maddie had been living at one of the swankiest houses in the area, Blackwell Manor. Alex stays with the Blackwells herself, keeping a safe distance from their rich but miserable lives—until things take a turn when another young woman goes missing. As Alex becomes a thorn in the police’s side, she uncovers secrets about the present and the distant past. Dark sexual themes feature amid the absorbing suburban suspense that’s told from multiple, tantalizing viewpoints.
