Having no idea exactly how reliable the information in this book is, it was a reasonably fun read and shows some of the insider tricks that a Privatre Investigator can use to obtain information, and locate Missing Persons. How successfult such tactics are, bears some evidential efforts, but nonetheless, they seem realistic and believable. This book was a much better read than a similar book I tried, in that it was well laid out and the information well organised. It was concise, didn't ramble with too much irrelevant junk and got right to the point...which is what you want from this sort of book. I found myself laughing at many gags, wondering how real they were, but still impressed by their gravitas. So, all in all, I am glad I read this book. What I learned could indeed help me in my career.
