A child has been taken. Snatched in the dead of night from the safety of the family home. There's no sign of forced entry, no one heard or saw a thing. DI Sean Corrigan investigates. He needs to find four-year-old George Bridgeman before abduction becomes murder. But his ability to see into dark minds, to think like those he hunts, has deserted him just when he needs it most. And then another child vanishes. What kind of monster is Corrigan hunting? And will he work it out in time to save the children?
