Alphy and Geordie keep an eye on rising tensions as a controversial figure is invited to speak at the university. When a murder is committed, however, they disagree on how to approach the case.

There’s no shortage of murder, mystery, and mayhem in the seemingly quiet 1950s Cambridgeshire village of Grantchester—and police detective Geordie Keating (Robson Green) and the resident vicar (played by James Norton, Tom Brittney, and Rishi Nair, respectively) are always on the case. There’s a real warmth to this period crime drama, set in a picturesque location with central characters who’ve formed their own version of a family.

In Season 10, Alphy’s really found a home in Grantchester. In Geordie too, he’s found a best friend and his intellectual equal. Love proves more elusive, until a case throws him in the path of a romance. But before he can let anyone else in, he must confront truths about himself. Geordie, meanwhile, wrestles with his expectations for his own son and Cathy takes steps to better her career with the help of Mrs. Chapman.
