Kat and Lock

Kat Frank knows all about loss. A widowed single mother, Kat is a cop who trusts her intuition. Picked to lead a pilot program that has her paired with Lock, an AIDE (Artificially Intelligent Detective Entity)—a hologram that is activated by a device on Kat’s wrist—Kat’s gut reactions about people and motives come up against Lock’s statistical calculations and data analysis that can be devised in seconds. But as the two missing person’s cold cases they are reviewing suddenly become active, Lock is the only one who can help when the case begins to target Kat personally.

DCS Kat Frank knows all about loss. A widowed single mother, Kat is a cop who trusts her instincts. Picked to lead a pilot programme that has her paired with AIDE (Artificial Intelligence Detective Entity) Lock, Kat's instincts come up against Lock's logic. But when the two missing person's cold cases they are reviewing suddenly become active, Lock is the only one who can help Kat when the case gets personal. AI versus human experience. Logic versus instinct. With lives on the line can the pair work together before someone else becomes another statistic?

When the body of a man is found crucified at the top of Mount Judd, DCS Kat Frank and her partner, AIDE (Artificially Intelligent Detecting Entity) Lock, of the Warwickshire Future Policing Unit, have their work cut out for them. Previously only dealing with cold cases, the FPU are thrust into the spotlight as another body is found – also crucified – and it appears as though there is a serial killer on the loose. But why these victims? And who will be next?

When the body of a man is found crucified at the top of a hill in the British midlands, AIDE Lock—the world’s first AI Detective—and Detective Kat Frank are thrust into the spotlight as they are given their first live case. When a second body is found the police issue an extraordinary warning to local males aged between 30 and 40 years old. With the national media and local men in an uproar, Kat and Lock have to combine their instincts and algorithms to catch the killer before they can strike again.

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. And as the stakes rise for the team, so do the tensions brewing within it. 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 about what happened with relentless logic.
