A wealthy tycoon accused of murder needs Keyes to find the only person who can clear him. Jeff's only clue is that her picture was taken during a thirty minute period at Niagara Falls.

Jeff's latest case is to steal a priceless painting from a Greek billionaire and replace it with a forgery.

Keyes must rescue a kidnapped billionaire, but his mission is endangered by the man's paranoid aversion to germs.

Keyes final assignment is personal: he tries a diamond heist to get revenge on the African ruler who paid for his job with a million dollar rubber check.
