I Spy, How to be a Private Investigator by Daniel Ribacoff
on CD 5 discs
This is a great book to learn some details about privacy and how to defend yourself against snoops and also to get information when you need it.
Without going into great detail, you’ll get the feel and experience of being a PI by listening to this book on CD. He has some great insights and I suggest it is worth finding at your library or buying a copy.
This is a great book especially as an audio book.
