The Saint in the Sun — Leslie Charteris

Whether in Cannes, Saint-Tropez, Nassau, or Lucerne, the Saint always finds some action to interest him. In these seven stories, Simon faces competition in the jewel-thief business, encounters an unpleasant movie mogul, uncovers a Ponzi scheme that isn't what it seems, deals with sabotage in the world of motor racing, finds a missing body, tangles with the Russians, and rescues an heiress.
