Robson Green and Tom Brittney return to investigate more crime in the Cambridgeshire village of Grantchester. It\'s 1958, and Reverend Will Davenport heads off with the vicarage family to a holiday camp for a well-deserved break. But disaster is never far away as camp owner Roy Reeves is found dead one morning, causing a reluctant Geordie to get involved when he sees the local police botching the crime scene. Soon, Will and Geordie suspect a possible poisoning.
