Starring James Franciscus, Karl Malden, Pier Paolo Capponi, Catherine Spaak

A blind man (Malden) and his adolescent niece become witnesses to a grisly murder, which precedes a string of related deaths and corporate conspiracy. They team up with a newsman, Carlo (Franciscus), to put an end to the killing. Superb thriller, even if I struggled to follow its plot at times. The final fight upon the roof tops is spectacular, and a certain violent death that involves an elevator shaft is glorious. All the hallmarks of Argento’s best: gory, beautiful color, and a great ’70s score.
