Cast of Silent Witness: Full Cast List Across 29 Seasons

Silent Witness has been running since 1996, but it took a real character study to keep audiences hooked across nearly three decades. The show’s secret? Building around a core team that fans actually care about — then knowing exactly when to bring in fresh faces. By season 28, a pair of new arrivals shifted the team’s dynamics in ways viewers are still talking about.

Seasons Aired: 29 · Lead Actress: Emilia Fox as Dr. Nikki Alexander · Lead Actor: David Caves as Jack Hodgson · Original Lead: Amanda Burton as Sam Ryan · Notable Past Cast: William Gaminara, Tom Ward

The following table consolidates the key factual milestones across the show’s long run.

Who is the cast of The New Silent Witness?

The phrase “new Silent Witness” usually signals one thing: someone is catching up after a multi-season gap. The current core ensemble has been in place since 2025, when season 28 brought two significant permanent additions to the Lyell Centre team.

Current main cast

• Emilia Fox — Dr. Nikki Alexander, forensic pathologist (Cosmopolitan entertainment coverage)
• David Caves — Jack Hodgson, forensics expert (Cosmopolitan entertainment coverage)
• Francesca Mills — Kit Brookes, crime scene analyst (ScreenRant cast guide)
• Maggie Steed — Professor Harriet Maven, head of the Lyell Centre (ScreenRant cast guide)

Recurring characters

Beyond the four principals, recurring faces differ by season. Season 28 featured Sean Pertwee as DI John Flynn and Zoe Telford as Chief Superintendent Jane De Freitas (What to Watch season guide). Season 29 adds Zita Sattar as DCI Jilly Bashir for the opening two episodes (Cosmopolitan entertainment coverage).

What’s notable is the staying power of the two longest-serving leads — Fox and Caves together account for over three decades of screen time in the series.

Who is in Silent Witness season 28?

Season 28 aired starting January 6, 2025, and consisted of five two-part stories across ten episodes — a structure that allowed each new character room to develop rather than appearing in a single episode (Rotten Tomatoes official listing).

Returning stars

Emilia Fox and David Caves continued as the series’ emotional anchor. Their partnership, now entering its thirteenth year for Caves, has become the show’s most consistent through-line since the exit of earlier leads like Amanda Burton and William Gaminara.

New additions

Maggie Steed’s Professor Harriet Maven arrived as the new head of the Lyell Centre, bringing a different leadership energy than her predecessors. Francesca Mills debuted as Kit Brookes, described as enthusiastic and quick on her feet since her introduction (Wikipedia overview).

Francesca Mills herself said upon joining: “I’m thrilled to be joining such a long-running, much-loved series as Silent Witness and I really look forward to being a part of the stellar cast” (What to Watch season guide).

Several season 27 characters did not return — Velvy, Gabriel, and Cara were absent in season 28, marking one of the more noticeable roster resets in recent years (What to Watch season guide).

The implication: this kind of roster reset is rare for Silent Witness, making the season 28 additions particularly significant for the show’s long-term direction.

Who is in series 29 of Silent Witness?

Series 29 keeps the core cast unchanged while introducing a notable location shift — the team moves from the Lyell Centre to Birmingham’s Sir William Bowman Centre of Excellence (Cosmopolitan entertainment coverage).

Full cast list

The returning main ensemble for season 29 includes Emilia Fox, David Caves, Francesca Mills, and Maggie Steed (Cosmopolitan entertainment coverage).

Episode 1 specifics

Episode 1 sees the team settling into the new Birmingham facility, with Zita Sattar appearing as DCI Jilly Bashir for the first two episodes. Later episodes feature Gerrard Kearns as DC Jono Magath (episodes 5-6), Philip Cumbus as Richard Mazar, and Nathan Wright as Steve Gantry (Cosmopolitan entertainment coverage).

No major cast changes were reported between season 28 and season 29 beyond the location shift and new guest stars (Radio Times season preview).

The pattern: the Birmingham relocation signals a new chapter for the Lyell team while preserving the core cast that viewers have followed for over a decade.

Who are the new characters in Silent Witness Season 28?

Season 28 marked the most significant injection of new blood since some of the original ensemble departed. Two additions stood out for their potential to reshape team dynamics over subsequent seasons.

Key new roles

Professor Harriet Maven (Maggie Steed) arrived as the Lyell Centre’s new head, a position that carries narrative weight given the show’s focus on institutional leadership within forensic science. Kit Brookes (Francesca Mills) joined as a crime scene analyst, bringing a different energy to the investigative team.

Guest appearances

Beyond the new permanent additions, season 28 featured notable guest stars including Sean Pertwee (DI John Flynn), Lorcan Cranitch (Colin McGrath), Zoe Telford (Chief Superintendent Jane De Freitas), and Tamzin Outhwaite (Sally) (What to Watch season guide). Sarah Kameela Impey appeared as Tina Steadman (episodes 3-4) and Zaqi Ismail played Harry Singh (Digital Spy episode guide).

The catch: guest stars in season 28 were largely episodic, meaning only the permanent additions of Harriet Maven and Kit Brookes represent lasting changes to the show’s cast structure.

Who is the new character in Silent Witness?

Viewers returning after a hiatus typically ask about Kit Brookes first — she’s the most visible newcomer, introduced in season 28 as a crime scene analyst who brings fresh enthusiasm to the team.

Recent season newcomers

Francesca Mills’ Kit Brookes has the longest runway ahead, currently embedded in the core ensemble for both seasons 28 and 29. Her character description — “enthusiastic and quick” — suggests a younger perspective on forensic work that contrasts with the seasoned approach of Fox’s Dr. Alexander and Caves’ Jack Hodgson (Wikipedia overview).

Past changes

The show has cycled through several “new” characters over its run. William Gaminara’s Leo Dalton and Tom Ward’s Harry Cunningham were long-serving members who eventually departed. The pattern has been consistent: new additions stay for multiple seasons before cycling out, making each permanent arrival significant for the show’s long-term shape.

What this means: Kit Brookes represents the most recent permanent addition, and her multi-season presence suggests the show is investing in her as a long-term character rather than a short-term guest.

What the cast and fans say

“I’m thrilled to be joining such a long-running, much-loved series as Silent Witness and I really look forward to being a part of the stellar cast.”

— Francesca Mills, actor (Kit Brookes), What to Watch season guide

“Viewers will witness Kit becoming more established in her role, feeling secure in her ability to tackle complex cases.”

— Francesca Mills on her character’s development in season 29, Radio Times season preview

“The BBC drama has sustained 29 seasons partly by balancing consistency with periodic refreshes.”

— BBC media coverage analysis

For fans deciding whether to catch up or continue watching, the current cast structure offers something rare in long-running TV: a core duo (Fox and Caves) who have grown with their characters for over a decade, surrounded by new energy that genuinely changes team dynamics rather than just adding guest faces. Kit Brookes’ development across seasons 28 and 29 will be the key storyline to watch for newcomers evaluating where to start.
