Priceless: How I Went Undercover to Rescue the World's Stolen Treasures by Robert K. Wittman and John Shiffman. John Shiffman is a Landon grad, so I can offer this testimony: If this book is as good as the parties he had in his basement circa 1983, it’s bound to be worth reading. One Amazon reviewer writes: "Priceless has just about everything you'd want in a book, with appeal to all sorts of readers. In light of the recent art heist in Paris, this is timely and fascinating. Wittman's exploits do indeed read like a crime thriller, keeping the pages turning in a breathless fashion."
