This book was so well written that at times I found myself wondering if this was a simple murder mystery or something supernatual. Once again the history lesson was well done and it was spooky enough to have me on the edge of my seat. The ending was a bit predictable when it is revealed who the bad guy is, but I didn't put two and two together until the final chapters. There wasn't a lot of further character development for Maura or Jane during this book, instead the plot specifically focused on the murders and the mysterious club that believed in angels and demons and ancient Egyptian gods and goddesses.
