Grantchester is a British TV series starring Robson Green, Tessa Peake-Jones, and Al Weaver.

A Cambridgeshire clergyman finds himself investigating a series of mysterious wrongdoings in his small village of Grantchester.

In Series 3, Episode 3, a murder suspect is identified because he has 'form', ie he was in Borstal as a teenager because of stealing. However, as the show progresses it is clear this was man was not the culprit.

In Series 5, Episode 3, the murder victim is a young man who was in care as a child. He is a movie enthusiast, pretending he's American and a former scriptwriter with connections in Hollywood. He is killed by a young woman who finds out he can't help her become famous.

In Series 6, Episode 2, the head of a local adoption agency is killed and the ethics of adoption is questioned.

Series 8 opens with the murder of a young man who was orphaned as a child and taken in by another family. This is a “cuckoo in the next” story.

The series initially featured Sydney Chambers (James Norton) as the vicar. Next was William Devenport (Tom Brittney) and from Season 9, it has been Alphy Kottaram (Rishi Nair).

In series 10 it is revealed (from Episode 5) that Alphy Kottaram was a foundling and was raised in the Bithah Foundling Home. The man who runs the Foundling Home – which is closing - Stuart Potts (Paul Copley) is pleased to have him back and calls him Alpheus.

In that same episode, one of the children, Joshua, falls down the stairs and dies.

*Spoiler Alert* - it is one of the other children in the Home who is responsible for Joshua’s death.

Discussion about what happened when Alphy was born and whether he should try to locate his mother is ongoing for the rest of the series.
