The Bloodstained Shadow.
A young schoolgirl is viscously murdered and the killer is never caught.
Moving forward several years, professor Stefano goes to visit his brother Paulo a priest who lives on an island near Venice, and gets caught up in a series of brutal murders.
and also befriends Sandra(Stefania Cassini from Suspiria) who is an artist that he previously met earlier on the train.
This i found was a very entertaining giallo from 88Films. It has lots of suspense and twists and turns with various sub plots involving psychics and a pedo chap. bags of atmos in the misty Venetian alley ways and a great Goblin like score. Yes, it is a bit slow in parts and quite long in it's running time. but the murders when they come are quite nasty and well done, especially the
old ladys head being pushed into the fire.
so i award 80.7 out of 100 for this enjoyable giallo.
