When practising what you preach is easier said than done ... Professor Maxie Reddick has her reasons for being sceptical of traditional policing methods, but, in between her criminology lecturing job and her Criminal Thoughts podcast, she stays firmly on the side lines of the crime solving world. Then a young woman is brutally attacked, and suddenly it's essential that Maxie turns her words into actions; this is no longer an academic exercise - this is somebody's life. But as she delves deeper, the case takes a sickening turn, which leads Maxie to the horrifying realisation that the attack might not have been a one-off. It seems there's a depraved individual out there seeking revenge, and they'll stop at nothing to get it ... little by little ... one by one.
