THE PLACE: Seawings, a beautiful Art Deco home overlooking the sweep of the bay in Midtown-on-Sea.

THE CRIME: The gilded Holden family - Piper and Gray and their two teenage children, Riva and Artie - has vanished from the house without a trace.

THE DETECTIVE: DS Saul Anguish, brilliant but with a dark past, treads the narrow line between light and shade.

One late autumn morning, Piper’s best friend arrives at Seawings to discover an eerie scene – the kettle is still warm, all the family’s phones are charging on the worktop, the cars are in the garage. But the house is deserted.

In fifteen-year-old Riva Holden’s bedroom, scrawled across the mirror in blood, are three words:

Make
Them
Stop.

What happens next?
