Charles Piper has had three fraud investigation books published in the past few years. All three provide his insight and knowledge obtained through decades of experience conducting investigations. The Investigator and Fraud Fighter Guidebook is actually used as the textbook to train students of private investigation! All three of these books incorporate "The Piper Method of Conducting Thorough and Complete Investigations" and include testimonials from some of the most respected and experienced fraud fighters and investigators in the USA.
Piper also wrote a book about getting the most out of Major League Baseball's Spring Training. (All teams train in Arizona or Florida before the regular season starts.) It's full of color photos and useful tips on where, when and how to get autographs, catch free baseballs and photo ops with the players.
