The story takes place in the seemingly idyllic, upper-class community of Eastlake, which the book likens to "living in a goldfish bowl" because everyone knows everyone else's business. When security scanners are installed in a local self-service shop to catch petty shoplifters, the effort inadvertently uncovers dark secrets about the residents. The protagonist, Steve Manson, who runs a magazine exposing the corruption of the rich and powerful, becomes entangled in the situation when his wife is caught shoplifting. The scandal rapidly escalates into blackmail and murder, forcing Manson to confront a web of deceit. The novel is known for its twists and suspenseful, unexpected ending.
