Body of Lies by Jo Callaghan

Body of Lies by Jo Callaghan

The brand-new thriller featuring DCS Kat Frank and AIDE Lock, from the award-winning Sunday Times bestselling author of In the Blink of an Eye.

Human suspicion. AI manipulation.
When truth can be rewritten, who can you trust?

DCS Kat Frank is back at the Future Policing Unit after a devastating loss - and straight into her most disturbing case yet.

On Halloween night, a local MP is found murdered. Beside the body is a taunting message in binary code, aimed directly at Kat:

Catch me if you can.

The victim was a vocal opponent of AI. The motive looks political. But as Kat investigates with her partner, AIDE Lock - the world’s first AI detective - the case spirals into something far more dangerous.

Then a cyberattack takes down the National Grid.

With the country in chaos and lives on the line, Kat and Lock must track a killer who is always one step ahead. But in a world of deepfakes, deception and digital ghosts, instinct is no longer enough.

Kat must decide whether to trust the one thing she still fears most: her AI partner.

Because this time, Lock may not just be solving the case.

He may be changing what it means to be human.

Can Kat stop a killer before the lights go out for good?
