After a fruitless private investigation, De Beers still suspects that one of their executives is stealing diamonds and has asked for professional assistance. The characters are ordered to trail the prime suspect, a Mr. Julian de Haan, to see if they detect anything unusual in his movement or behavior. During the mission, the characters travel to the exotic streets of Zanzibar, to the wild savanna on a hunting-safari in Botswana, and to the air-conditioned vibrancy of a newly-renovated luxury casino in Macau, while discovering that more than just diamonds last forever.
