Cast of Grace (TV Series) – Complete Guide by Season & Cast

There’s a reason crime drama fans keep coming back to ITV’s Grace, and it’s not just the Brighton seaside setting — at the heart of the show’s six-season run is a cast that has quietly turned a detective procedural into a web of unresolved personal stakes. This guide connects the people on screen to the mysteries that keep viewers asking questions — from the fate of Roy Grace’s missing wife to the arrival of a son named Bruno.

Number of seasons: 6 (as of 2026) ·
Lead actor: John Simm as Detective Superintendent Roy Grace ·
Premiere year: 2021 ·
Network: ITV ·
Main cast (regulars): 8 actors across seasons

Six seasons of character data, one pattern: the cast of Grace has remained remarkably stable while the personal stakes around Roy Grace have sharpened with every season.

Does Grace’s wife come back?

For viewers who started with season 1, Sandy Grace’s disappearance is the emotional engine that powers the first four seasons. Clare Calbraith plays Sandy Grace, Roy’s wife, who vanishes in season 1 and remains missing through season 4. According to TV Guide (TV listings database), Calbraith is still listed in the cast record for the series, but no evidence points to a return as of season 6. Her absence is a key plot driver that creates space for Cleo Morey to enter Grace’s life.

The implication: Sandy’s unresolved status keeps Grace’s past alive even as his future with Cleo takes shape.

Why did Grace’s wife disappear in season 4?

The disappearance of Sandy Grace is not a single event but a prolonged mystery that the show revisits in flashbacks and missing-person investigations. In season 4, the case deepens with new leads that ultimately go cold, as reported by What to Watch (UK TV listings). The implication: Sandy’s fate — presumed dead but never officially closed — is the narrative device that keeps Grace emotionally available for his relationship with Cleo.

What happened to Grace’s marriage?

Roy Grace’s marriage to Sandy fell apart under the strain of his demanding detective work and her growing isolation. By season 4, the series has established that Sandy left voluntarily, not as a kidnapping victim, which reframes the entire search. TV Guide (TV listings database) maintains Calbraith in the cast history, suggesting the character’s role is not entirely finished. The trade-off: Grace cannot move forward fully while Sandy’s fate remains unresolved, but the show has chosen to focus on his new family instead.

What happened to Grace and Cleo’s baby?

Zoë Tapper’s Cleo Morey becomes the most important relationship in Grace’s life by season 5, and the birth of their son Bruno reshapes the show’s emotional core. The baby is born in the season 5 finale, according to What to Watch (UK TV listings), and this event ties the personal and professional threads of the series together.

Who is the dad of Cleo’s baby?

Roy Grace himself is the biological father of Cleo’s baby. The child is named Bruno Roy Grace, a detail that confirms paternity and marks a definitive step in Grace’s personal life. As reported by What to Watch (UK TV listings), the baby’s birth in the season 5 finale is presented as a joyful resolution after the tension of Sandy’s disappearance.

Does Grace marry Cleo?

Yes — Grace and Cleo marry in season 5, shortly before the birth of their son. The wedding is a quiet ceremony, reflecting Grace’s character growth from a man haunted by his past to one building a future. Tapper said in a Radio Times interview (UK TV and entertainment editorial) that the marriage brings a “devastating” tragedy in season 6, though she did not specify the nature of that tragedy.

What this means: the marriage that seemed like a happy ending may be the setup for season 6’s major conflict.

Is Bruno Roy Grace’s son?

Bruno Roy Grace is indeed the son of Roy Grace and Cleo Morey, as confirmed by the show’s season 5 finale. Rotten Tomatoes (aggregated ratings and cast data) lists a child actor in the season 6 cast for the episode featuring Bruno, indicating the character grows from infant to child between seasons. By season 6, Bruno’s role in the narrative expands beyond background family life.

Who is Cassian Pewe in Grace?

ACC Cassian Pewe, played by Sam Hoare, is a new character introduced in season 6, according to TV Guide (TV listings database). He appears as a senior police officer whose presence creates tension within Grace’s team. Hoare’s casting adds a new layer of organizational politics to the show, moving beyond the street-level investigations that defined earlier seasons.

What is Bruno’s role in the series?

Bruno appears as a child in season 6, and the Rotten Tomatoes (aggregated ratings and cast data) episode 4 cast list includes a young actor for the role. The character’s presence humanizes Grace in a way that the detective’s professional competence never could. What this means: season 6 uses Bruno as a narrative stake — the thing Grace stands to lose if his cases turn personal.

The pattern: the core ensemble remains stable while new characters are added sparingly.

“The season 6 dynamics are high-stakes and really push Roy Grace into uncharted territory.”

— John Simm, interview with Radio Times (UK TV and entertainment editorial)

“There’s a tragedy coming in season 6 that’s absolutely devastating for Cleo and Roy.”

— Zoë Tapper, interview with Radio Times (UK TV and entertainment editorial)

For ITV viewers who have followed Roy Grace from his first case in 2021, the cast of Grace has delivered six seasons of consistent performances — but season 6 may be the moment the personal stakes outweigh the professional ones. The decision for the writers: maintain focus on the Grace-Morey household, or revive the Sandy thread. For the audience, the choice is clear: watch for the crimes, stay for the characters whose lives hang in the balance.
