The series of novels by American academic and crime-writer Donna Leon, featuring Commissario Brunetti in Venice are easy reads.

I got hooked on them while traveling in Italy. I could listen to one audio book a day!

Read the first 5 starting with Death at La Fenice.

Ended up reading 11 more:

• Waters of the Eternal Youth 
• Friends in High Places
• Transient Desires 
• A Sea of Troubles 
• Wilful Behaviour 
• Uniform Justice
• Bad Guy Wins
• Willful Behavior
• Through a Glass Darkly
• A Question of Belief 
• Give Unto Others

Recommended.
