** spoiler alert ** 
 It took me a while to read this book. I kept having to put it down for several reasons: 1. I was super busy with work which meant that I kept 2. Trying to read it at night and falling asleep. And 3. It was super creepy and a little unnerving, so that was another blow to my "read it at night before bed" plan. It was similar to the first two Cormoran Strike novels in that Rowling gives you a few suspects, and you know one of them is the killer, but she writes it in such a way that it's difficult if not impossible, to figure out which it is. That's what I love about the series though, trying to piece it all together because you know the killer is one of the options. The main killer in this book definitely haunted my thoughts at times and was overall very creepy. Some of the murders were graphic, adding to the "can't read this before bed" aspect. The connections with the Blue Oyster Cult songs only added to the creep factor. The end of the novel was a bit of a cliff hanger about Robin and Cormoran's future. Typical! Guess I'll have to wait for the next one to come out!!
