Grantchester cast

James Norton and Robson Green return as the unlikely 1950s crime fighting duo, Vicar Sidney Chambers and Police Inspector Geordie Keating, for the first series, which is based on The Grantchester Mysteries by James Runcie.

Tessa Peake-Jones is back as Sidney’s sharp tongued housekeeper Mrs Maguire who keeps the vicar in check; Morven Christie reprises her role as Sidney’s forbidden lover Amanda and Al Weaver returns as the timid curate Leonard Finch.

Kacey Ainsworth is back as Geordie’s long suffering wife Cathy, Lorne MacFadyen puts his police helmet back on to play DC Phil Wilkinson and Seline Hizli returns as the feisty police secretary Margaret. And of course it wouldn’t be Grantchester without the return of the gorgeous black Labrador Dickens.

In tonight's sixth and final episode of the series, Sidney visits the Archdeacon to discuss his resignation. Sidney has lost his faith in a church that won’t allow him to be married to the woman he loves. With a heavy heart the Archdeacon tells Sidney he must go away and write a resignation letter in order to make it official.

Sidney visits Amanda, revealing his plan. Their moment of joy is cut short when Amanda asks if Sidney has told Mrs Maguire or Leonard… To Sidney’s relief, Leonard seems happy for them, but Mrs Maguire can’t contain her upset.

On his way out of the vicarage the next morning, Sidney spots Mrs Maguire crying, and then encounters Leonard, who is now wondering about his own future, should a less tolerant vicar move in. Sidney feels incredibly guilty but tells Leonard it has to be his decision.

In church, Sidney puts on his dog collar and leads a service, thinking his days within the village are now numbered but when a little boy called Jacob is abducted Sidney finds that the community need him more than ever.


Meanwhile, Mrs Maguire must prepare for her own future whilst struggling to come to terms with Sidney’s imminent departure. Geordie’s behaviour grows increasingly erratic as he struggles to cope with the mess he’s made of his family life, and as Sidney and Geordie move closer to discovering who has kidnapped Jacob, Sidney must choose to move forward with Amanda in London, or be there for his best friend Geordie in his hour of need.

Grantchester airs at 9PM on ITV.
