Deep Red 4K 1975

During a lecture at a congress of parapsychologists, a woman who was giving a lecture and guessing the names of those in the audience and what they had in their pockets, went into a seizure, claiming that there was death in the audience, that she was seeing a horrible murder in a villa, that she was hearing a children's song. And that same night she is brutally stabbed to death with a huge cleaver by a man in a trenchcoat whom the jazz pianist saw. Unwittingly, the pianist is drawn into the story and begins his own investigation.
