ITV viewers are preparing for the return of one of the network’s most compelling detectives as DSI Roy Grace steps back into the spotlight for a brand-new instalment of gripping investigations, haunting personal struggles, and dark twists that continue to define his turbulent career. Since first appearing on screens in 2021, the committed and quietly tormented investigator has become a standout figure in modern British crime drama, capturing the attention of millions with his razor-sharp instincts and unflinching pursuit of truth.
From the outset, Roy Grace was never portrayed as a conventional detective. Viewers were introduced to a man who was highly capable, fiercely dedicated, yet emotionally wounded. His professional successes stood in stark contrast to the deeply personal anguish that followed him into every case. The disappearance of his wife, a tragedy that occurred years before audiences first met him, continues to cast a long, chilling shadow over his life. Despite being known for cracking some of Brighton’s most brutal and perplexing crimes, Grace has been unable to solve the one mystery that matters most to him: what happened to the woman he loved.
The emotional weight of that unresolved trauma has always distinguished Grace from other on-screen investigators. Though respected by colleagues for his persistence and intuition, his inner turmoil frequently threatens to overwhelm him. It is this very conflict—between the detective who brings order to chaos and the man who cannot find answers in his own life—that has kept audiences invested and eager for his next chapter.
Now, as ITV prepares to launch the fourth series of the acclaimed drama, fans will soon see the veteran investigator once again stepping into the line of duty. The new series is scheduled to debut on Sunday 1st September at 8pm on ITV and ITVX, promising another run of suspense, danger, and emotional depth. Alongside his loyal and long-term partner, Detective Sergeant Glenn Branson—portrayed by Richie Campbell—Grace is expected to face a fresh set of disturbing cases that will test both his professional abilities and personal resilience.
Branson’s significance in Grace’s life cannot be overstated. More than a colleague, he has become a stabilising force—someone who recognises the detective’s pain but also respects the boundaries Grace keeps tightly in place. Their partnership has matured noticeably over the previous series, evolving into a dynamic built not only on trust, but on mutual understanding born from weathering trauma and conflict together. As the stakes rise in the upcoming episodes, Branson’s role as both ally and sounding board will be more crucial than ever.
ITV insiders have hinted that the new series takes a darker turn, not simply in the crimes the pair investigate but in the emotional terrain Grace must navigate. While the detective has long pushed himself into work as a coping mechanism, there are growing suggestions that the façade is beginning to crack. The longer his wife’s disappearance remains unsolved, the more he struggles to compartmentalise the emotional fallout. And yet, even as his personal life remains frozen in uncertainty, villains across Brighton continue their relentless march, forcing Grace to confront horrors both new and familiar.
The cases lined up for the new series are expected to be some of the most complex yet. Viewers can anticipate storylines involving chilling twists, morally ambiguous suspects, and investigations that blur the line between justice and revenge. Early whispers suggest that the emotional and psychological intensity will be heightened, placing Grace at the centre of conflicts that challenge his methods, his relationships, and perhaps even his future within the police force.
ITV has demonstrated tremendous confidence in the drama’s direction, particularly with John Simm’s commanding portrayal of Grace at the helm. His nuanced performance—balancing grit with vulnerability—has been key to the show’s success and its steady growth in popularity. Fans have praised Simm for delivering a character who feels both heroic and human, capable of extraordinary deductive prowess yet deeply scarred by the unresolved wounds of his past.
As anticipation builds for the September premiere, audiences are left wondering whether this could be the series in which Grace finally uncovers new leads about his wife’s disappearance. While the network remains tight-lipped on spoilers, teasers indicate that personal revelations may intertwine with professional challenges more closely than ever before.
One thing is certain: as the clock counts down to the return of Brighton’s most troubled detective, ITV is gearing up to deliver another emotionally charged, tension-filled journey into the mind of a man who solves everyone’s mysteries but his own.
