While the specific city is not mentioned, the novel's atmosphere suggests a typical North American suburb. Tree-lined streets, manicured lawns, and well-maintained homes paint a picture of upper-middle-class domesticity. This seemingly idyllic environment serves as a stark contrast to the dark events that transpire, highlighting the notion that danger can lurk behind even the most pristine surfaces.

Key scenes unfold within the protagonists' homes, particularly during the fateful dinner party next door. The claustrophobic interior settings—from living rooms to bedrooms— become charged with suspicion and secrets as the investigation progresses. This interplay between public and private spaces underscores the theme of appearances versus reality that runs throughout the novel.
