DI Barton Books in Order

The Recommended Reading Order for DI Barton

If you want to experience Ross Greenwood’s gripping police procedural series the way it was intended, you should read the DI Barton books in publication order. Because the books follow the ongoing personal and professional life of Detective Inspector John Barton, his family, and his team at the Peterborough Major Crimes Unit, reading them out of order will spoil key character developments, relationship arcs, and career changes.

The series begins with The Snow Killer (2019), which introduces DI John Barton as a refreshingly grounded family man—a stark contrast to the standard trope of the self-destructive, brooding detective. From there, each book raises the stakes, building on the relationships of the recurring cast while presenting a standalone, self-contained mystery. Below is the complete reading path for the series.

Chronological Order and Caveats

The chronological order of the DI Barton series matches the publication order exactly. The books progress linearly from 2019 through the mid-2020s, mirroring the passage of time in real life. While each novel features a self-contained crime that is resolved by the final page, the underlying subplots—such as Barton’s transition to a desk job and his eventual return to the field in The Village Killer—are highly dependent on continuity.

For instance, starting with The Village Killer will spoil the status of Barton's team and reveal major shifts in his career that occur at the end of the first six books. To fully appreciate the emotional weight of Barton's journey and his relationships with his colleagues and family, start with the debut novel.

The Peterborough Setting: A Character of Its Own

One of the most praised aspects of the DI Barton series is its vivid setting. Ross Greenwood is a Peterborough native and uses his intimate knowledge of the city to ground the stories. Locations such as Netherton, Oundle Road, the quiet village of Castor, and even the local prison, HMP Peterborough, are described with realistic detail. This authentic sense of place makes the city feel alive, acting as a gritty backdrop that reflects the themes of the novels. Many fans have even visited Peterborough to walk the same streets DI Barton patrols.

Ross Greenwood's Real-Life Inspiration

Before becoming a full-time novelist, Ross Greenwood worked for four years as a prison officer at HMP Peterborough. This real-world experience inside the prison system heavily influences the DI Barton books. Greenwood's background allows him to write police procedures and criminal psychology with a level of realism and empathy rarely seen in the genre. Instead of focusing solely on shock value, his novels explore the complex motivations of criminals, the flaws of the justice system, and the heavy toll that police work takes on individuals and their families. This perspective is also highlighted in his standalone thriller Prisoner (2021), which is based directly on his time as a prison guard.

Beyond DI Barton: The Norfolk Murders Connection

Fans of DI Barton looking for more of Ross Greenwood's writing should explore the Norfolk Murders series (also known as the DS Ashley Knight series). Beginning with Death on Cromer Beach, this series follows Detective Inspector Ashley Knight and her team solving cases across the rural landscapes of Norfolk. While both series exist in the same region of England and share a similar gritty procedural tone, they operate as distinct storylines. John Barton and Ashley Knight do not meet or cross paths, allowing readers to enjoy the Norfolk Murders as a separate, companion experience without needing to coordinate reading orders between the two series.
