Frank Montgomery and his family love their life in the placid suburb of Lake View. Members of the seven households on Horseshoe Drive form an extended family. Like any family, they occasionally play practical jokes on each other. But the harmless pranks suddenly turn ugly, even obscene.

Frank digs deep into his neighbors' lives and discovers that motives for the murder abound. Secrets reveals a dark side of suburbia. It's enough to make you wonder about your neighbors. Who are they really? What are they up to? Are you watching them? Are they watching you?
