His work includes Infamous, Detectorists, Mr Bates vs The Post Office, the voice of Dobby in Harry Potter and an Olivier-winning performance in The Play What I Wrote.
Dr Michael Rycroft

Dr Kam Karimore

Dr Fleur Perkins

Her many recognisable roles include Doctor Who, EastEnders, Outlander, Bergerac and pub landlady Mae in Ted Lasso.
Regular doctors and temporary colleagues
The sequence includes Bullard, the early temporary colleagues Peterson and Rycroft, and the later regular pathologists Wilding, Karimore and Perkins. A permanent handover and a one-case substitute are different kinds of change. The table gives each named doctor a place in the sequence without turning a brief appearance into a long appointment.
The medical team also follows a different rhythm from the sergeants. A new police partner need not arrive with a new pathologist, and a doctor may span more than one investigating partnership. The comments below are a spoiler-light reading of the existing character descriptions and named episode connections. Compare the first case and a later one before deciding which working relationship you enjoy most.
The pathologists and their cases
Dr George Bullard — Barry Jackson
George Bullard is the original long-serving medical colleague, played by Barry Jackson. He belongs to Tom Barnaby’s professional world and continues briefly into John Barnaby’s early period. The character material describes an unflappable doctor with a dry wit and a long friendship with Tom. That gives the medical scenes a different kind of familiarity from the changing inspector-and-sergeant partnerships.
Bullard’s broad span includes exceptions: some cases use a locum or guest pathologist, and some refer to medical findings without showing him on screen. A long run therefore should not be read as an identical appearance in every episode between the endpoints. Start with the linked first case, then compare a later investigation to see how the established relationship operates alongside different police partners. The character page brings selected Bullard cases together.
Dr Dan Peterson — Toby Jones
Dan Peterson, played by Toby Jones, covers a short early spell during Bullard’s absence. The episode data identifies Strangler’s Wood, Dead Man’s Eleven, Death of a Stranger and Judgement Day as his cases. They sit among the early Tom Barnaby investigations rather than forming a permanent change to the medical team. That explains why a viewer moving through the early series can encounter another doctor before returning to Bullard.
The existing description gives Peterson a brisk, precise manner in the forensic work. Compare the four linked stories if you want to follow the whole short run. A locum’s first and last appearance answers a different question from the beginning and end of a long-term appointment. The table keeps him in the overall order, while his own character page gives the more focused route through those particular cases.
Dr Michael Rycroft — Michael Bertenshaw
Michael Rycroft is the guest pathologist in The Electric Vendetta, played by Michael Bertenshaw. This is a single-case entry in the early medical chronology, during an absence by Bullard. Including him prevents an apparently complete list of the regular doctors from overlooking the named colleague attached to this investigation. His first and last entries coincide because the same story supplies both endpoints.
Use the episode page for his cast context and the other people in that investigation. A one-off doctor should be understood through the particular credit rather than given a larger fictional biography without evidence. If you are comparing the early medical scenes, place this appearance alongside Peterson’s short locum run and Bullard’s continuing role. The contrast helps separate a temporary colleague from a longer change in the programme’s regular team.
Dr Kate Wilding — Tamzin Malleson
Kate Wilding, played by Tamzin Malleson, is Bullard’s regular successor in the John Barnaby period. Her run occupies Series 14–17. The character material describes an assured, no-nonsense professional with a more informal chemistry around John’s team. That combination keeps the medical findings authoritative while giving the exchanges a different character from Bullard’s long familiarity with Tom.
Wilding’s arrival and the changes among the sergeants are separate parts of the chronology. Compare her cases with the relevant police partnerships rather than assuming every team member changes at the same series boundary. Her character page links the selected episodes and her actor page keeps the performer’s wider credits distinct from the fictional doctor. Those two routes are useful for readers arriving through either a character name or Tamzin Malleson’s name.
Dr Kam Karimore — Manjinder Virk
Kam Karimore is played by Manjinder Virk and belongs to Series 18–19. Her period crosses the transition from Charlie Nelson to Jamie Winter. That makes her a useful point of continuity when comparing those two versions of John Barnaby’s team. The existing character material describes her as highly capable and forthright, bringing a direct style to the forensic exchanges.
For a short viewing route, begin with her first case in the table and follow the surrounding series order. Then compare the police partner before and after Winter’s arrival. The medical colleague can remain familiar while another working relationship changes. Karimore’s character profile and the linked episode pages keep those combinations visible, with the actors’ pages available when your interest is in the performers rather than the order of the fictional team.
Dr Fleur Perkins — Annette Badland
Fleur Perkins is played by Annette Badland and takes over as the regular pathologist from Series 20. The Ghost of Causton Abbey is the character’s introduction. The existing profile pairs forensic certainty with dry humour and a conspicuous lack of patience for Midsomer nonsense. That description is the starting point for our reading of the role; the linked cases let you compare the exchanges for yourself.
Perkins’s run belongs to John Barnaby and Jamie Winter’s established partnership. The latest case shown in the table is a boundary of the episodes listed here, not an announced farewell. Keep that distinction when comparing an older guide with newer cases. If you are starting with this team, follow her introduction and then continue through the series index, using the individual episode pages for cast, places and the sealed solution when you are ready.
Following the whole Causton team
For a complete team comparison, use the sergeants in order beside this list. The episode-order guide gives the viewing sequence, and the character hub connects the family members as well as the police and medical colleagues. The German equivalent is the Gerichtsmediziner guide.
When searching for a particular doctor, retain the character name, actor and original episode title together. This avoids confusing a performer’s different guest role with a recurring medical character. It also gives you a precise place to restart a viewing run: one named case, one team combination and a clear link to what follows.
