A stranger. A child. A liar who will stop at nothing…

When six-year-old Marcus is taken from outside his house on Halloween, there is only one witness: a frightened teen determined to keep himself hidden.

After an anonymous tip off, Detective Imogen Grey is called out to an expensive Exeter street, caught up in the buzz of the holiday. But when the police visit Marcus's house, his parents claim everything is fine. Imogen is sure there is more to the family than meets the eye. But just how much more, she could never have imagined…

What has happened to little Marcus? And will he ever come home?

Smart, shocking and twisty – perfect for fans of Cara Hunter, TM Logan and Karin Slaughter.
