Causton's resident pathologist. Bullard goes about his work with a professional skill and a cheery personality. He is a good friend of Tom Barnaby's and has been a regular throughout the series (save for a brief spell, when his place was taken by Dr. Dan Peterson played by Toby Jones). In later episodes, Bullard has often played a greater role in the plot, even making a sterling appearance in the Midsomer Worthy Choir in "Death in Chorus". In one episode, he admits to the "accidental" death of his wife while on tour at a slaughter house. At the end of "The Oblong Murders", Bullard tells Barnaby that he's going to take some time off to do some fishing with his sister in a holiday in Ireland. He has not returned.
