Murder, kidnapping and the theft of an ancient Mayan statue, both 500 years ago and today, and diving in cenotes on the Mayan Riviera all come into play in this Mike Scott adventure. Speaking at his alma mater, Mike Scott learns that the death of a friend 25 years before might not have been an accident. That discovery, and the revelation of who was behind the murder, sends Mike on a hunt to find a missing Mayan statue that contains the "heart of the Maya" before a lunatic drug dealer with delusions of grandeur kills a friend and corrupts the Mayan people.
