I've always been fascinated by stories of undercover work, and this book fits the bill. Mark has a way with words, and you are sucked into this tale that cracks along. Starting his undercover work in the post-Mr Asia era, we are taken into a world of drugs, violence & crime. It's also an interesting look into what policing was like in the late 70s & early 80s, from attitudes and just how things operated. Now working as an international fraud investigator, I found these stories to be equally as fascinating. Dealing with millions of dollars, various countries & international fraudsters makes for interesting reading – I bet there's many more stories that didn't make it into this book!
