Will is pursued by the tornado of the Dark and prepares for the final battle. He flies with Merriman on the great white horse to where Herne the ancient hunter is waiting. Herne summons his hounds – a pack of huge white animals ghostly in the half-light. Listen on headphones for 3D immersive sound. #TheDarkIsRising
