The Snack Thief by Andrea Camilleri

In the third book in Andrea Camilleri's Inspector Montalbano series, the urbane and perceptive Sicilian detective exposes a viper's nest of government corruption and international intrigue in a compelling new case. When an elderly man is stabbed to death in an elevator and a crewman on an Italian fishing trawler is machine-gunned by a Tunisian patrol boat off Sicily's coast, only Montalbano suspects the link between the two incidents. His investigation leads to the beautiful Karima, an impoverished housecleaner and sometime prostitute, whose young son steals other schoolchildren's midmorning snacks. But Karima disappears, and the young snack thief's life as well as Montalbano's is on the line . . .
