This book was very easy to follow along and enjoy as a crime novel with a twist. The concept of AI vs traditional policing felt very well executed and unique. I really loved the characterisation of 'AIDE' and DCS Kat and the interactions they had with one another which allowed for an element of humor i wasn't expecting. 

Writing wise i enjoyed the use of interview transcripts and the varied POV to a cold case victim which helped break up the pace of the book and set the 'crime' atmosphere. 

I will say the plot itself did have points which felt a bit predictable (

E.g. the cold cases being connected. That the DCS son would eventually be involved.

this didn't greatly impact the my overall enjoyment and is worth a read.
