This was my first book by Elizabeth Haynes but it definitely won't be my last. From the first page I was pulled in and the pacing didn't let up. I loved DCI Louisa "Lou" Smith. She was tough but compassionate and capable but also very human. Plus, anyone who exists primarily on KitKat bars and coffee is pretty great! The mystery itself is intriguing and it was very easy to keep the large cast and all the different threads straight. Haynes mixes in transcripts of reports and witness statements in the story itself which I hadn't come across before. It took me a chapter or two to get used to it but once I did I really enjoyed it. It was a quick way to get the information to the reader without having to have characters discuss it. I also enjoyed that the chapters were divided by day and that the breaks within the chapter were headed with a time code. It gave a sense of urgency to the reading and I really felt caught up within the investigation. I didn't care for Andy Hamilton but I don't think I really was supposed too. I didn't love the sex or romantic relationships between some of the characters where it wasn't related to the murder but that's purely personal. This is the first in a new series and I'm definitely looking forward to seeing more of Lou.
