Leave No Trace by Jo Callaghan

I had been waiting quite some time to be able to read ‘Leave No Trace’ by Jo Callaghan, as I was a big fan of ‘In the Blink of an Eye‘, which I read towards the end of last year. I wanted to find out more DCS Kat Franks and her team, and where in Warwickshire the next book would be set.

This was just as engaging as the last book. This time, there is a serial killer who appears to be targeting men in the local area of Nuneaton. DCS Franks and her team are in a race against time to try and bring the killer to justice before they strike again. Working alongside Locke, again, we follow their investigation and we consider the question, who is the better detective – human or AI? And there is quite an interesting moment with DNA, where a machine may not have the reaction that a person would, and does this lead to an important clue being missed? Yet there is another brilliant moment where AI can do something that a human would never be able to do and it does, again, raise questions about the pros and cons of AI.

I did have an idea who did it, but at the same moment as DCS Franks and her team. So, I do not think that is a bad thing as it meant that I had followed the same clues and come to the same conclusions as the experts, so as an armchair detective I will take that. There are, of course, some chilling moments, especially the chapters told from the perspective of the murderer, but this is a police procedural book, so we are following them as they solve the crime. And, fantastically. at the end of the book we are left with a bit of a ‘cliffhanger’ as we see where the next story may take us.

Returning to this book was like rejoining a group of friends and becoming in invested in the next stage of their story. Each one of them has a tale that you are a little invested in and feel you are checking in with them all, making sure that they are all OK, and things are working out with them all. There are also some tense moments that will keep you reading, as you have to know how things are going to turn out.

So, yet again, I am left ready to read the next book, and I can’t wait to see where the next case will take us, and how DCS Franks and her team are doing.

In the Blink of an Eye by Jo Callaghan

This is a book that (no surprise) I have been meaning to read for ages. And when it was recommended by a number of people I admire, I knew I had to pick it up and give it a read.

Now, there are so many reasons that I loved this book. Firstly, I found it fascinating that it was about bringing AI into police work. How would removing human emotion impact police work? Would it bring more efficiency to the process? There is so much to unpack here, as there were moments of admin that the AI was certainly pretty efficient at – being able to watch hours of CCTV for example. But it is true that sometimes the human touch and a little emotion is not a hindrance but a help. As well as this, there was the intrigue of how DCS Frank works with the AIDE (Locke); how he becomes almost human when she needs someone to speak to or share ideas with. Although that does come with its own dangers – as she soon finds out…

Alongside this, there was the brilliant crime thriller element of the book. Someone goes missing every 90 seconds, one could say ‘in the blink of an eye’, and it becomes DCS Franks job to decide which cases about missing people the team should return to and hopefully solve for their families. When she spots the connection, it brings it all a little close to home – but there are no spoilers here, so you will have to read the book if you want to know how.

And, finally, I know the area that this book is set in very well. There is something rather fun about reading about an area you know in a good book. Especially when there are even some quite niche references like that hardware store on the high street… I would quite like DCS Kat Franks’ cottage, too, but I think that is an actual work of fiction (or has been moved from one end of the town the other).

Overall, Jo Callaghan has crafted fantastic characters in a fantastic crime thriller. And I am now rather excited to read ‘Leave No Trace’, because this is a world I would like to enter again. This book deserves all the accolades it has received, and I am already recommending it to all the crime/thriller fans I know.
