Winter 1963: two children have disappeared in Manchester; the murderous careers of Myra Hindley and Ian Brady have begun. On a freezing day in December, another child goes missing: 13-year-old Alison Carter vanishes from the isolated Derbyshire hamlet of Scardale. For the young George Bennett it is the beginning of his most difficult and harrowing case: a murder with no body, an investigation with more dead ends and closed faces than he'd have found in the inner city; an outcome that reverberates down the years.

Decades later he tells his story to journalist Catherine Heathcote, but just when her book is poised for publication, Bennett tries to pull the plug. He has new information that he will not divulge, and that threatens the very foundation of his existence. Catherine is forced to reinvestigate the past, with results that turn the world upside down.

A taut psychological thriller that explores, exposes and explodes the border between reality and illusion in a multilayered narrative that turns expectations on their head and reminds us that what we know is what we do not know...
