About this listen

FROM THE AUTHOR OF THE SUNDAY TIMES BESTSELLER IN THE BLINK OF AN EYE
Winner of the Theakston Old Peculier Crime Novel of the Year 2024
Winner of the Crime Writers’ Association ILP John Creasey (New Blood) Dagger 2024

One detective driven by instinct, the other by logic.
It will take both to find a killer who knows the true meaning of fear . . .

When the body of a man is found crucified at the top of Mount Judd, DCS Kat Frank and AIDE Lock – the world’s first AI detective – are thrust into the spotlight with their first live case.

But when they discover another man dead – also crucified – it appears that the killer is only just getting started. When the Future Policing Unit issues an extraordinary warning to local men to avoid drinking in pubs, being out alone late at night and going home with strangers, they face a hostile media frenzy. Whilst they desperately search for connections between the victims, time is running out for them to join the dots and prevent another death.

And if Kat and Lock know anything, it’s that killers rarely stop – until they are made to.

Very well read.

Loved it

The characterisation of main characters: DCI kat and AI Locke was believable. The concept of AI being introduced into the police force - the writer made this possibility real rather than sci fi by mixing fast big data availability and human responses.
