The Houseguest: a Novel Reprint edition

Chuck Burgoyne is no ordinary houseguest. The Graveses (father Doug; wife Audrey; son Bobby; and daughter-in-law Lydia) have gotten used to his polite manners and gourmet breakfasts. But one morning at the Graveses' summer home, Chuck fails to appear.
When Chuck finally does surface, he is no longer sweet and charming, but rather has become aggressive and arrogant, abusing each family member in turn. Each family member that is, except the fellow outsider, Lydia. Once Chuck rescues her from the dangerous undertow of the ocean, Lydia can't help but feel obligated to him, even after his uninvited advances to her while she's half asleep. Slowly it becomes apparent to the family that Chuck isn't anyone's guest but rather a perfect stranger who wormed his way into their home. Yet the Graveses are so concerned with not offending him by being impolite that they willingly accept the abuse he freely dishes out. In private, however, they all scheme for his undoing. But will anyone muster up the courage?
An eerie and clever novel, The Houseguest introduces one of Berger's most dangerous and compelling villains.
