When night falls, fear spreads...

The Lake District: a wild landscape, rife with stories. Detectives Zoe Barnes and Sam Taylor are called to investigate the disappearance of two children.

But they quickly realise they have been drawn into a complex and unnerving case that hides a much darker intent: as they dig deeper, whispers grow of a community hiding a deadly secret - and talk of witches, the like of which hasn't been heard since the seventeenth century, is spreading.

Zoe and Sam will have to work fast to save lives; but in this atmosphere of fear and mistrust, can they even rely on each other?
