Keeley Hawes is set to join the second season of a hit ITV crime series. She will portray a paediatric surgeon who becomes the focus of an investigation led by Detective Sergeant Annie Cassidy, played by Eve Myles.

The 31 million streams that cemented ITVX's record-breaking hit

The first season of the crime drama featuring DS Annie Cassidy became an immediate cultural phenomenon, according to the source. The series launched on ITVX and achieved 31 million streams, a figure that eclipsed all previous streaming records on the platform. This massive viewership suggests a growing appetite for high-tension police procedurals that blend character depth with fast-paced plotting.

Viewers have already labeled the series as "gripping" and one of the standout dramas of 2026. The success of the first season was driven by the performance of Eve Myles and the writing of George Kay, who crafted a story centered on the disappearance of a school headmaster's wife. This foundation has set a high bar for the second season as it moves into new territory.

Why paediatric surgeon Ruth Manning is the next target in Bristol

In the upcoming season , Keeley Hawes joins the cast as Ruth Manning,a devoted and pre-eminent paediatric surgeon. According to the official synopsis, Ruth Manning works at Bristol's Makeway Hospital, where she is highly respected for her commitment to her patients. However, this professional prestige becomes a shield for a darker narrative.

The plot will see DS Annie Cassidy, played by Eve Myles, place Ruth Manning in her crosshairs. The investigation will explore whether the surgeon has been hiding the truth about a series of historical crimes,potentially justifying her silence for the "greater good" of her patients. This dynamic introduces a moral complexity to the show, pitting the legal pursuit of truth against the perceived ethics of medical care.

The influence of Detective Julie Mackay and Robert Murphy on the series

The series is not merely a work of fiction but is deeply rooted in real-world investigative experience. As reported in the source, the show is inspired by the professional careers of Robert Murphy, an ITV Crime Correspondent, and Julie Mackay, who served as a Detective Sergeant for the Gloucestershire Police. This connection to actual police work provides the series with an authenticity that resonates with audienes who crave realism in their crime dramas.

This trend of blending fictional narratives with the blueprints of real-life investigators has become a staple of modern prestige television. By drawing from the complex cases handled by Robert Murphy in the West of England, writer George Kay ensures that the obstacles faced by DS Annie Cassidy feel grounded in the actual challenges of British law enforcement.

The missing release date for the upcoming Bristol filming schedule

While the excitement for the return of DS Annie Cassidy is high, several key details remain unconfirmed. ITV has yet to announce a specific release date for season two, though it has been confirmed that filming will take place in Bristol next year.
