This is one of the many books that Donna Leon has written which takes place in Venice and features Commissario Guido Brunetti. They are all very entertaining.

The story begins when two injured young American girls are dumped off outside a hospital. They cannot remember what had happened to them and who left them outside the hospital, and that is the beginning of the mystery.
It turns out to have a very dark beginning which involves many people and brings to light something that has been going on for a long time. He and his second-in-command, Claudia Giffoni, follow many clues and go into dark places to solve this crime. It is one of the many books that Leon has written, and an entertaining read.
