On Halloween night, four households gather for a party in the tiny Yorkshire village of Black Gale. Three hours in, they head outside, onto the darkened moors, to play a drunken game of hide and seek. None of them return. There\'s no trail, no evidence and no answers. An entire village has just vanished. With the police investigation dead in the water, the families of the disappeared ask missing persons investigator David Raker to find out what happened. But nothing can prepare him for the truth.
