Season 1 - Episode Guide

Detective drama set in a 1950s Cambridgeshire village, where local vicar Sidney Chambers (James Norton) develops a sideline in sleuthing - with the initially reluctant help of grumpy DI Geordie Keating (Robson Green). The cleric's first case finds him presiding over the funeral of a solicitor, who is believed to have taken his own life. However, the dead man's mistress has a different theory - and feeling unable to go to the police, she asks Sidney to examine it for her. He uncovers evidence that the suicide was staged, but while he's busy delving into the personal life of the victim, will the vicar miss his own big chance with Amanda Kendall (Morven Christie), the woman he secretly loves?

Poor Sidney. His sister Jen bullies him into attending Amanda's engagement dinner - seeing the love of his life celebrate her betrothal to another man is the last thing the village vicar wants. He sinks a few too many drinks in a bid to make the evening more palatable, but it doesn't work - in fact, nobody at the event seems happy. Tensions rise between Amanda and Jen's old school friends, and then matters erupt when Jen's boyfriend Johnny (Ukweli Roach, Starlings) is accused of stealing Amanda's engagement ring. Later, the unfortunate chap is accused of murdering one of his fellow guests, and evidence at the scene of the crime seems to back up the theory. But Sidney isn't convinced - can he unmask the real killer?

A heartbroken Sidney agrees to help parishioner Isabel prepare for her wedding to Arthur, the new man in town, but the bride's stubborn mother, Daisy, proves to be a big impediment to the occasion as she believes the groom is out to kill her. When Daisy is then found dead, Mrs Maguire calls in Geordie to investigate, and Sidney finds himself dragged into the case - despite vowing to leave police business behind. While the victim seems to have died of natural causes, Arthur and Isabel are pushing for a fast cremation, suggesting the couple have something to hide.

Sidney is woken in the early hours by a fire in the village and, putting his life on the line, races to rescue Marion Taylor from the burning house, much to the relief of her husband Dominic. But there are questions surrounding the blaze - was it really an accident, and why was Marion so reluctant to leave? Normally Sidney would turn to Geordie to help solve a mystery like this, but he finds the detective is far from his usual self. When Dominic is then found stabbed to death, it's Geordie's junior, Atkins, who is sent to head up the case - and he's not exactly a fan of interfering vicars.

Sidney takes Geordie to Johnny Johnson's London jazz club, hoping to leave their worries in Grantchester for the night, but the backstage murder of Johnny's sister Claudette puts paid to that. When Archie, the victim's father and owner of the club, calls in a police officer pal to crack the case, Geordie immediately detects the copper is corrupt, while Sidney makes an important discovery about Claudette that she had kept hidden from all but those closest to her. As every lead seems to come back to Archie's violent past, recriminations within the family begin to play out.

With Amanda and Guy's wedding fast approaching, and his betrayal of Hildegard still fresh in his mind, Sidney is thrown deep into crisis, and the murder of a local cop doesn't help matters as he allows himself to become drawn into another case with Geordie. However, tragedy strikes as the duo close in on the killer, and with Geordie's life hanging in the balance, the clergyman finds himself cut out of the investigation as the police close ranks. But that doesn't stop him enlisting the help of Mrs Maguire and Leonard in a daring mission to gather information on the man who shot his partner.
