Book excerpt: A Martini Club search begins, almost casually with a marital dispute between a beautiful woman and her wandering husband. The quarrel evolves into sweeping questions about stolen art, undercover agents, religious conundrums, Fibonacci sequences, politics, and—of course—billionaires with billions to spend. Colorful locations, energetic personalities, and a chimpanzee named Chappie. All play a part in discovering the real object of the search: a find that bids fair to change how we think about our history, or faith, and our lives.
