Career source: BIFA profile ↗Toby Jones’s Midsomer roles
Toby Jones plays the locum pathologist Dan Peterson in four early Tom Barnaby investigations. The role list connects Strangler’s Wood, Dead Man’s Eleven, Death of a Stranger and Judgement Day. These are appearances by one medical character, unlike the unrelated guest parts taken by some returning Midsomer actors. The distinction matters when counting roles: four credited episodes do not mean four different fictional doctors.
Peterson supplies a temporary forensic presence during George Bullard’s absence. The dedicated character guide explains that place in the medical team, while this performer page keeps the episode credits beside Jones’s wider career. For a rewatch, follow the four cases in series order and compare the doctor’s brisk professional exchanges with the established Tom-and-Troy partnership. This is the Casebook’s suggested viewing route, without adding a private biography or an invented departure for the character. The cast sources below support the particular appearances, and the episode links open the rest of the cast, filming places and spoiler-controlled case information.
