SYNOPSIS:

DCS Kat Frank and AIDE Lock return in the provocative new thriller from the author of In the Blink of an Eye.

‘A smart, agile, immaculately plotted and moving thriller that is unswervingly gripping and scary, and at the same time beautifully tender and humane’ NICCI FRENCH 
‘Chilled me to the bone and I couldn’t turn the pages fast enough. Callaghan writes with such intelligence; interspersing humour with moments of utter heartbreak’ NIKKI SMITH
 
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, AIDE Lock – the world’s first AI Detective – and DCS Kat Frank are thrust into the spotlight as they are given their first live case.
 
But with the discovery of another man’s body – also crucified – it appears that their killer is only just getting started. With the police warning local men to be vigilant, the Future Policing Unit is thrust into a hostile media frenzy as they desperately search for connections between the victims. But time is running out for them to join the dots and prevent another death.
 
For if Kat and Lock know anything, it’s that killers rarely stop – until they are made to.

MY REVIEW:

DCS Kat Frank and AIDE Lock are back thrust into the spotlight when they finally get to investigate their first live case in the second instalment of this gripping crime series. The pair are called to an unusual crime scene where a man has been found crucified at the top of Mount Judd. And when the body of a second man is found crucified it seems that their killer is just beginning. Local men are warned to stay vigilant as the Future Policing Unit face a race against the clock to find and stop the culprit before they kill again. 

Compelling, tense and surprising, I couldn’t put this one down. This time around the duo find themselves embroiled in a case that makes national headlines, putting them under even greater pressure. While the first book focused more on the sci-fi aspect of an AI detective, this time around there is less sci-fi and more crime, allowing Jo Callaghan to showcase herself as a crime writer to watch. I enjoyed the darker tone she took this time around and this is exactly the kind of twisted thriller that sings to me. After enjoying the audiobook last time I decided to listen again and loved it. I particularly enjoyed how the killer’s pov is told in an echoey way that is so eerie it sent chills down my spine every time I heard it. Even just thinking about it is making me shiver. 

I loved being back with the Future Policing Unit. Kat and Lock are a unique and fascinating detective team and I loved their banter and camaraderie, which has grown since their rocky start in the first book. But it is only their second case and they are still learning how to work together, something that can be tricky when one of them is driven by instinct and the other by logic. I like how well they balance each other out; one’s weaknesses being the other’s strengths, and how they both were learning to be better officers by including some of each other’s methods. I also really liked that Lock is no longer treated as a perfect detective. We see some of his limitations and flaws, which kind of humanises the AI detective a little. It certainly made me warm to him more this time around. 

Riveting, pacy, and filled with nerve-shredding tension, Leave No Trace is an action-packed thriller that will keep you on your toes. Now I just have to wait impatiently for book three.
