When an elderly man is stabbed to death in an elevator & a crewman on an Italian fishing trawler is machine-gunned by a Tunisian patrol boat off Sicily`s coast, only Inspector Montalbano suspects a link between the two incidents. His investigation leads to the beautiful Karima, an impoverished house cleaner & sometime prostitute, whose young son steals other school children`s mid-morning snacks. But Karima disappears, & the young snack thief`s life as well as Montalbano`s is endangered when the inspector exposes a viper`s nest of government corruption & international intrigue.
