Pre-order BODY OF LIES, the brand-new thriller in the Kat and Lock series, coming Spring 2026.

THE TRUTH WILL ALWAYS COME OUT – BUT AT WHAT COST?

Fresh from successfully closing their first live case, the Future Policing Unit are called in to investigate when a headless, handless body is found on a Warwickshire farm. But as they work to identify the victim and their killer, the discovery of a second body begins to spark fears that The Aston Strangler is back.

When DCS Kat Frank is accused of putting the wrong man behind bars all those years ago, AIDE Lock – the world's first AI detective – pursues the truth with relentless logic. But Kat is determined to keep the past buried, and when she becomes the target of a shadowy figure looking for revenge, Lock is torn between his evidence-based algorithms and the judgement of his partner, with explosive results.

When everything hangs in the balance, it will all come down to just how much an AI can learn, and what happens when they do…

Enjoyed this latest Kat & Lock story. i like the use of real W Midlands place names. The narrator seems to have all 'locals' as being from the Black Country, not accurate to the locality, but this area is notoriously difficult for actors (cf the whole Peaky Blinders cast). I was able to guess the main murder mystery outcome but it was interesting. it was mixed with an old case / this time it's personal thing. I like the development of Lock and the slight suspicions/intimations of sentience.

Another good installment

Such.a unique and compelling series that gets better and better with each book. Really makes you think about the potential benefits and dangers of AI in policing and life in general. Can’t wait for the next book

Brilliant police procedural series

This series just keeps getting better and considering how much i loved the first two books that is saying something. This series really should be read in order. Even though the crimes the duo of Kat and Lock and their team solve is completed in each of the books the arc about the AI involvement is essential in what makes this series standout from other police procedural stories. The narrator does a wonderful job.

Fantastic
