第 1 季，第 6 集: With Amanda and Guy’s wedding fast approaching, and his betrayal of Hildegard still fresh in his mind, Sidney is thrown deep into crisis. With even those closest to Sidney struggling to get through to him, is he truly cut out for life as the vicar of Grantchester? The murder of a local policeman doesn’t help matters, as Sidney allows himself to be sucked back into another investigation rather than putting his house in order. However, tragedy strikes as Geordie and Sidney close in on the killer. With Geordie’s life hanging in the balance, and the killer still on the loose, the police close ranks, cutting Sidney out of the investigation. Believing that the police are on the wrong track, Sidney asks Mrs Maguire and Leonard if they will undertake a daring mission to help him gather much needed information about the killer.
