In this gripping psychological thriller, a new family moves onto Hogarth Street and shows their neighbors that sometimes the most perfect families are hiding the most terrible secrets.

Everybody wants to live on Hogarth Street, the pretty, tree-lined avenue with its white houses. The new family, the Wests, are a perfect fit. Katherine and John seem so in love and their gorgeous five-year-old twins race screeching around their beautiful emerald-green lawn.

But today, they won't invite you in when you knock, they brush away offers to babysit and the children haven't been seen.

Every family has secrets, and on the hottest day of the year, the truth is about to come out. As a tragedy unfolds behind closed doors, the dawn chorus is split by the wail of sirens. And one by one the families who tried so hard to welcome the Wests begin to realize: Hogarth Street will never be the same again.
