Wonderful series. Beautiful scenery and architecture in Rome and Venice. The black and white makes it perfect. Great plot but it took me until the third episode to really become intrigued. The acting on all parts is wonderful and the opening song by Roy Orbison is one that brings back memories of my high school days. Could have had a bit more of Italian songs but one sung by the lady is perfect. The coon cat at the apartment is beautiful and makes this even more enjoyable. I would recommend it, especially to those who appreciate a great thriller.
