It is a perfect summer day in London’s up-market Brockwell Park. Yet, behind the elegant facade of one house, a man and his wife have been taken prisoner in their own home and their young son has disappeared. But the final horror of their terrifying ordeal is still to be revealed. Called in to investigate, Jack Caffery tries desperately to make sense of the meager clues found at the crime scene. But the echoes of a devastating disappearance in his own past make it impossible for him to view the crime objectively. And as Jack digs deeper, as the disturbing parallels between past and present mount, the real nightmares begin.
