Not nearly as good as Goldman's book, but still effective. Steiger played a psycho who had a love/hate relationship with his mother and after her death he began acting out his hatred of mother by killing older women. As nearly all serial killers are younger men than Steiger, I think his part should have gone to Segal instead. This film had a good story, performances, and was fast paced, making for a tense and suspense filled tale.
