Sylvia Syms

There's a heatwave in St Saviour In The Marshes this week and it's giving Adam (Tom Hollander) some very disturbing nightmares. One of his parishioners (guest star Sylvia Syms) is having sleepless nights for a different reason. She thinks her care home is haunted and wants Adam to perform an exorcism. Nigel, in particular is only too happy to oblige.

This is a slightly disjointed episode, but fans of Jimmy Akingbola from Holby will be very pleased to see him make his first appearance this series as Mick. He's only in one scene, but it's hilarious.

And the other revelation this week is getting to meet Adam's five-year-old god-daughter Enid (Olivia Riley). After just an hour with her and her blessed recorder (you may want ear-plugs) Adam and Alex (Olivia Colman) start to wonder whether having children of their own is such a good idea after all.

Dreaming of being a mother, Alex gets a chance to try out her parenting skills when a friend's daughter, Enid, comes to stay. She's not a charming child: "Shut up, I hate you!" It's all made worse by the fact that London is in the grip of a heatwave and an exhausted Adam is suffering with nightmares. With a storyline involving an elderly parishioner (Sylvia Syms) who's convinced her nursing home bedroom is haunted, an episode that has fun with the more eldritch currents of parish life.
