Who is Gareth Fisher?
Gareth Fisher is the editor of the fictional East Anglia Advertiser, where Lucy works in Series 2. Mark Bonnar plays him, with credited appearances in Episodes 1, 2, 3, 5 and 6. His newsroom becomes a second workplace for the programme, alongside the Cambridge police station. John has a formal consulting role with Carter’s team, while Lucy develops a route into the James investigation through reporting.
David Mitchell’s comments reported by CultBox describe Gareth as a comically hapless newspaper editor. That mix of professional responsibility and comic frustration fits the newspaper’s place in the story. Lucy needs access and introductions, and Gareth is the person she has to persuade. Her urgency meets the demands and limitations of another workplace.
The East Anglia Advertiser gives Lucy more to do than wait for John to bring information home. Her work puts her in contact with people connected to James’s enquiries and makes interviews part of the search. Gareth’s role is important because he sits at the point where her private reason for asking questions meets the newspaper’s public business.

Full story
Show the full story — spoilers
At the end of Series 2, Gareth joins the alliance assembled at the newspaper to investigate Joanne Kemper. The group includes John, Lucy, Henry, Russell Carter, Ethan Cole and Caitlin Sullivan. Their meeting brings the family’s search and the police investigation into one shared effort, with the newsroom becoming a place where their findings can be compared.
TV Guide’s finale account records Gareth pointing out that the group is still missing a victim. He spots a gap in the list they have assembled. The observation changes the question they need to ask next: the deaths they know about may not yet account for the whole pattern James was following.
The finale does not name that additional victim. Gareth’s contribution leaves the alliance with a fresh lead to pursue, alongside the evidence already connected with Kemper. His editor’s perspective is valuable here because he is looking at the shape of the story the others have gathered. He notices the absence that prevents their account from feeling complete.
Kemper is still free after John exposes Ziegler’s staged accusation. James is still missing. The newspaper gathering therefore comes at a difficult point: the group has gained a clearer understanding of the chief constable’s death without securing the result it wanted against the MP. Gareth helps turn their attention towards the next piece of work.
The ending also changes the scale of Lucy’s newspaper role. What began as a way for her to seek access now provides a meeting place for people who want the same answers. Gareth is part of that wider commitment. The police officers, the Taylors and the editor bring different experience to a case that can no longer be carried by John and Lucy alone.

Relationships
Lucy is Gareth’s main connection to the story. She arrives with a strong reason to seek interviews and information, while he has a newspaper to run. Their exchanges give the James investigation another kind of friction: progress depends on persuading an editor as well as solving the next clue. Lucy’s determination keeps the search moving through the newsroom.
John and Carter belong to the police side of the programme, so Gareth offers a useful change of setting and professional outlook. He is not part of the station’s chain of command. The newspaper gives the characters a place to approach the same mystery through reporting, contacts and discussion. Henry’s research adds another strand to the material Lucy is bringing into that workplace.
Continue with John Taylor, Lucy Betts-Taylor, Russell Carter and the James mystery.
About Mark Bonnar
Mark Bonnar gives Gareth a comic role within a story that is often tense for Lucy. The editor’s difficulties make the newsroom lively without removing its importance to her enquiries. His presence also widens the ensemble beyond people who respond to John as a police consultant. Gareth can bring a different emphasis to a conversation because his working day is organised around a newspaper, not the detectives’ latest case.
