This was a solid procedural mystery/thriller. Set in London, it follows a Black detective, who is recently back in the field after a not-yet-disclosed traumatic experience, and her trainee partner as they hunt for a copycat serial killer. I enjoyed the intra-team dynamics in this book more than I usually do in crime novels. (Usually I'm more along the lines of: I don't care about your relationships with your colleagues, give me the mystery!) I do think there are some things to be said about how women characters are used in this story to enable/justify/excuse awful decisions by male characters ... but I've found most books in the mystery/thriller genre can offend my feminist sensibilities so I digress. ;)

One thing that I found *very* interesting as a U.S.-based reader was that there were NO GUNS in this book. Again: NO GUNS! So U.K. I honestly felt like I was reading an alternate-reality sci-fi novel at times. How would this investigation have differed if everyone had guns?! The detective even put a "stab vest" on at one point. I was definitely intrigued by this gun-free world of crime.
