Midwinter of the Spirit boasts a stellar cast, with Anna Maxwell Martin leading the way as Merrily Watkins, one of just a few woman working as an exorcist and a single mother still reeling from the death of her unfaithful husband in a car crash. 

When two seemingly unconnected deaths shake the countryside, Merrily is called upon to assist the police with their enquiries.

Adapted by BAFTA award-winning screenwriter Stephen Volke (Afterlife and The Awakening), this edgy crime drama is sure to disturb with its supernatural twist!

The three-part drama will air tonight on ITV at 9pm but you can go back to the start with Wine of Angels and follow the entire Merrily Watkins series through Isis audiobooks.
