Uma Borboleta com as Asas Ensanguentadas

While walking through a park in a rainy day, the young Françoise Pigaut (Carole André) is stabbed to death by man wearing raincoat and hat. Inspector Berardi (Silvano Tranquilli) is assigned to investigate the case and soon the TV anchor Alessandro Marchi (Giancarlo Sbragia) becomes the prime suspect. His daughter Sarah Marchi (Wendi D'Olive) was Françoise's best friend and their common friend Giorgio (Helmut Berger) had a crush on Françoise. Alessandro's friend and attorney Giulio Cordaro (Günther Stoll) defends him in the court but Alessandro is found guilty and sent to prison. When two other women are murdered and it is found that Alessandro's wife Maria Marchi (Evelyn Stewart) is the lover of Giulio, the defense asks for mistrial and Alessandro has another trial. Who might be the killer?

"Una farfalla con le ali insanguinate", a.k.a. "The Bloodstained Butterfly", is a crime story with a great twist in the end. The suspenseful screenplay begins with the presentation of several characters and is confused, and the slow pace is tiresome. But the story is good, and the unexpected conclusion surprises the viewer. My vote is seven.

Title (Brazil): "Uma Borboleta com as Asas Ensanguentadas" ("A Butterfly with the Bloodstained Wings")
