John Nettles as DCI Tom Barnaby

an English detective drama based on the books of author Caroline Graham. He is married to Joyce and has a daughter called Cully. When Tom retires, his cousin John Barnaby moves into Midsomer with his wife Sarah and dog Sykes. A senior member of Causton CID, Barnaby formerly worked for MI6. A patient, tolerant man, Barnaby's style of investigation is methodical and fair. Barnaby is a sagacious and perceptive individual, able to recognise seemingly obscure clues. Barnaby's social life revolves around his wife Joyce and his daughter Cully, who often provide a personal connection with the crimes that he is investigating. Barnaby's parents are both deceased by the episode "Blue Herrings". In his last appearance, "Fit for Murder", we learn that his father died on his birthday, at Barnaby's current age. When Barnaby announces his retirement, his family and colleagues are shocked and Joyce and Cully find this is weird. His wife once proposed that they moved out of Causton, but he was only put off and recalled some of the murders that had taken place in the various villages she suggested.
