Book excerpt: A unique memoir in which a young adventurer from colonial Rhodesia charms his way around the world, sleeping in stately homes and public toilets, smuggling drugs across several borders, and losing a $50 million fortune to the CIA, before settling into a stellar banking career. Looking back on a life well lived as he faces terminal illness, he swears that the key to his success was his grueling training as a Buddhist monk in a snowbound Japanese monastery.
