Part 3 of the terrifying supernatural crime thriller

A terrible, malignant power grows in strength on the Clarkson property. At nightfall the assault begins, trapping innocents alongside hardened criminals. A beast stalks them; a "Familiar", a monster capable of inhuman savagery, a creature of darkness that kills with pleasure and without remorse. But an unknown force prevents it from entering the house where the gang have taken refuge. For tonight, at least, the survivors have reached an uneasy truce. But the peace could explode at any second and leave more bodies in the wake - that is, if they're not all dead before dawn.
