Twenty-three-year-old Katy Speed has always been fascinated by the house across the street. The woman who lives there, Gloria, is the most glamorous neighbour on the avenue, owning a fashionable dress shop in Bexhill-on-Sea. But who is the woman who arrives in the black car most Saturdays while Gloria is at work? Sometimes she brings women to the house, and other times the women come with children.
Then one night, the house burns down. In the wreckage, the bodies of Gloria and her daughter are found. Katy is sure the unexplained strangers must be responsible, until her father is arrested and charged with murder.
Surely the police have arrested the wrong person? Is the rest of the street safe. Can Katy find the truth before it’s too late?
