Giallo alights in greener pastures (Ireland!) but the blood still runs red for this utterly gnarled tale of family secrets and deadly lies. After a young woman’s ghastly slaying, Dublin cop Luigi Pistilli (of Sergio Leone’s Clint Eastwood movies) tries to rattle skeletons in the closet of possibly implicated diplomat Anton Diffring—but much more comes tumbling out as the bodies pile up. With Valentina Cortese (Day for Night) and Dagmar Lassander as mother and daughter.
