I truly liked this book even with all the science in it, Neil Bradbury wrote it perfectly for the layman. It was actually the science that I really like about it. I knew some but Neil Bradbury explained it in a way that I could understand. You could tell that Neil Bradbury knew his stuff and dare I say enjoyed talking about poisons. I also liked that he wrote about how the poisons were used by the killers. I will be reading more from Neil Bradbury and recommend this to all my science and true crime friends. Thank you Netgalley, St. Martin's Press and Neil Bradbury, Ph.D. for letting me read and review this book.
