Interesting story about Myra Hindley and Ian Brady

It is difficult to determine whether this story is fact or fiction or a combination of both. It includes details, conversations and thoughts that could hardly be found from research.
One thing isn’t hard to believe — that they were both servants of the devil.

I am familiar with the Moors Murders but had not read anything about them in a long time. This was a very good read about two very sadistic serial killers who preyed mostly on children. I highly recommend this book to any true crime fan.

This book vividly describes Britain’s horrible Serial Killing duo of Ian Brady & Myra Hindley (The Moors Murderers-1960’s). It is very well-written in novel form and vividly takes you through their weird courtship to their killing spree. I enjoyed reading it (and got so caught up in it I wanted there to be more!) because the author knows how to write and kept the story and dialog tight and enthralling (this is something I don’t see much anymore so I really enjoy it when I do!). The read has a real British feel to it (as it was a British crime, after all but I like British & Australian writing) and I enjoyed how the story was told in an interesting fiction-type style instead of a simple re-telling that most True Crime fans know. The author did much research on this case and was able to express what was discovered subtly and the let the story unfold as if one was reading a deeply imaginative story instead of a stale listing of facts. This is not easy to do but David Cooper did it quite skillfully. I loved the ending because the book took a very interesting turn and it left me with some questions I immediately wanted to research and talk about with others, but it was late at night and I couldn’t, LOL! It also gave me a genuine creep-out which I more than enjoyed because I didn’t expect it. Read this book to find out more about The Moors Murderers or even a primer on how to write good, tight dialogue (something I personally am not good at so when I see it I like it!). I can see this book getting a NEW “True Crime” reader totally engrossed in the genre. I am still thinking about some of the things presented at the end and will be doing my own research into just what the truth is. This book won’t let you down if you’re a True Crime fan. Enjoy!

I have read about these two before, but nothing like this! It was a very good read, and took you into the mindset of these two very demented evil people!! They had no remorse or feeling for anything that they did! I am glad they got caught and couldn’t bring anymore pain to anyone else’s family! This is a definitely another great addition to any true crime library. Can’t wait to read more of your books!!

I enjoyed reading this book. It is well written and tells the story without fillers. These murderers are totally unfeeling. The devil made them do it because they were the devil’s spawn.
