The Bloodstained Butterfly.
A young french girl is brutally stabbed to death in the park and a man is seen running away from the scene of the crime wearing a beige raincoat. later the chap is arrested and convicted of the crime but more killings then follow.
This is a rather serious giallo directed by Duccio Tessari who was more famous for his westerns. it is extremely well made and intriguing but does lack the flamboyant style of your Argento and Fulci's and has very few murders and gore. and is a film that is more towards the police procedures and courtroom drama, but fortunately doesn't dwell too long on the legal side.
Acting is very good, with Helmut Berger playing the rather disturbed pianist boyfriend of the murdered french girl, and Evelyn Stewart from Case of the Scorpion's Tail in the role of a adultress wife.
As we all giallos though it keeps you entertained throughout and is a very worth while mystery. soundtrack is also very nice as well and mixes some classical into it too. a solid 78 out of 100.
