New investigation Comissioner Caffery, still tormented by the tragic loss of his younger brother. In this story, he investigates the owners of a small dog he collected: the neck of the animal escaped, was a note "Save us." The shadow of a manic hangs over the fate of a hostage family (owners of that bitch). We tossed false leads in false leads, the author forcing us to turn the pages of his book to know what happened because it is with a real sense of suspense that Mo Hayder has developed this new plot. And we enjoy meeting Caffery, as if the fate of the latter we mattered.
