Titles in this set: 1. In The Blink of An Eye 2. Leave No Trace Description: In The Blink of An Eye In the UK, someone is reported missing every 90 seconds. Just gone. Vanished. In the blink of an eye. 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 (Artificially Intelligent 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? Leave No Trace 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.
