I usually enjoy Martin Cruz Smith, especially his Arkady Renko series. This book was the exception.
The story takes place in Venice near the end of WW II. Cenzo, a fisherman who seems to be too well educated for his occupation, discovers a girl floating in the lagoon. It seems she's a Jew and is escaping from the SS. The plot was developing too slowly and neither of the characters were interesting to me so I gave up after reading about 60 pages of a 240 page book.
My advice is to give this one a pass.
