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.
My thoughts: Another absolutely brilliant case for Kat, Lock and the team. Now more established after the successful conclusion of their last big case, and their unit is able to command more resources supposedly, but it still comes down to the key group of Kat, Lock, the professor and Kat’s two detectives, Debbie and Hassan.
The team are searching for a killer who’s leaving men in open, but remote spaces, crucified. They’re sending a message, but to who?
It’s the first live case the team has been given, and the press are very intrigued, cue an awkward press conference. One reporter in particular seems to be ahead of the team, knowing facts about the case almost too quickly.
Lock is definitely developing a personality, even using sarcasm and humour, so the learning part of his programming is working, but curiously he seems to be wrestling with something.
Kat is also learning, learning how to be alone, now that her son Cam is at uni. She keeps buying food no one eats, and is struggling with the empty house and the quiet.
But the case gives her something to focus on for now, as the body count increases. And her new friendship with the pathologist, means she has at least one person to talk to apart from Lock.
It’s winter, and the killer is utilising the cold to help them finish off their victims, as snow sets in and one of the team falls into the killer’s clutches, can the others save them before they too succumb?
More gripping, clever and deeply interesting stuff. Lock grapples with the concept of humanity, the team are locked in a desperate race against time, the ideas that this series has, the thoughts I keep having while reading it, so, so good. Hooked.
