New York Times bestselling author B. A. Paris captivated psychological thriller readers everywhere with Behind Closed Doors. Now she invites you into another heart-pounding home full of secrets, in The Guest. Iris and Gabriel seem to have it all: a beautiful country home, a daughter taking a gap year in Greece, and their good friends from Paris, Laure and Pierre, always up for a holiday weekend away. But when a young man has a tragic accident in a nearby quarry, Gabriel is the one to find him and hear his final words, leaving Gabriel with a guilty burden. As Iris tries to help ease her husband's trauma, they acquire an unexpected house guest. Their friend Laure has seemingly moved in, her marriage in crisis after her husband Pierre's shocking reveal that he has had a child with another woman. At first happy to help their friend, Iris and Gabriel insist Laure stay as long as she needs. But Laure soon makes herself too much at home: wearing Iris's clothes, following her everywhere she goes, and asking questions about the now-closed quarry and the recent tragedy. Meanwhile, Pierre is refusing to answer Gabriel's calls. The only respite for Iris and Gabriel from the increasingly tense atmosphere in their own home comes in the form of new neighbors-a couple new to town and expecting their first child. But with them comes their gardener, Joseph, who has a checkered past. With fractured relationships and secrets piling up around them, can Iris and Gabriel's marriage survive?
