If you love crime dramas that keep you guessing long after the final scene, Unforgotten deserves a place on your watchlist. The acclaimed ITV series combines haunting cold cases, complex characters and devastating secrets, creating a detective thriller that is as emotionally powerful as it is mysterious.
For the first four seasons, Nicola Walker starred as DCI Cassie Stuart, a thoughtful and determined detective who specialises in investigating murders that have remained unsolved for years. Working alongside DI Sunny Khan, played by Sanjeev Bhaskar, she revisits cases that others might have considered impossible to solve.
Each season begins with a disturbing discovery, often involving human remains that have been hidden for decades. What follows is a painstaking investigation into the victim’s identity, relationships and final days, gradually exposing the secrets of people whose lives have continued long after the original crime.
But Unforgotten is not simply about finding a killer. Its greatest strength lies in examining how a single act of violence can affect families, relationships and entire communities for generations. Suspects are rarely straightforward villains, and the truth often reveals painful compromises, buried guilt and consequences nobody can escape.
Walker brings remarkable emotional depth to Cassie, a detective whose compassion frequently makes it difficult to separate her professional responsibilities from her personal feelings. Her partnership with Bhaskar provides the series with warmth and understated humour, balancing the grim subject matter without undermining its seriousness.
One of the show’s most memorable qualities is its willingness to challenge viewers’ assumptions. As new evidence emerges, seemingly ordinary people become entangled in the investigation, and early theories can collapse in an instant. The suspense comes not just from discovering who committed the crime, but understanding why it happened and what the truth will mean for everyone involved.
After Walker’s character departed at the end of the fourth series, Sinéad Keenan joined the drama as DCI Jessica James, bringing a new dynamic to the investigative team. The series continued to explore emotionally complex cases while preserving the thoughtful storytelling that made it stand out.
With six seasons already released and a seventh in production, Unforgotten has established itself as one of British television’s most compelling crime dramas. The upcoming seventh season is expected to arrive in early 2027, with Sunny and Jess investigating another disturbing cold case.
For viewers who enjoy intelligent mysteries with powerful performances and unexpected revelations, this is a series that rewards patience and close attention.
Because in Unforgotten, the most unsettling question is not simply who committed the crime — but what happens when a long-buried truth finally comes back to destroy the lives built around it?
