Friends of the Dusk by Phil Rickman

4.0

Merrily continues to annoy her superiors. There's a new bishop in charge and he doesn't believe in the deliverance (exocism) practice. Merrily's love life isn't closer to being sorted, and her daughter is having challenges in her own love life, and figuring out her career.
Merrily is asked to intervene for a family living in an old house with a mysterious past. The current occupants are a Muslim family and their non-Muslim in-laws. There seems to be a powerful and negative presence in the house.
The house and its surroundings are tied to a centuries-old story of an evil figure. There used to be a village and a castle. The village has all but disappeared and the castle is in ruins. Merrily and her fellow exorcist, the Welsh vicar, Huw, are in pursuit of the history, while Merrily avoids her bishop who wants to get rid of her.

Another decent chapter in the Merrily Watkins series.
