I really enjoyed this giallo despite its lack of the more traditional motifs of black gloved killers and stylized mayhem. The Designated Victim leans heavily into character drama. Our hero wants out of his loveless marriage and gradually becomes involved with a rich thrill seeker who will gladly kill his wife in order to experience that last kick. One thing leads to another and the story quickly becomes one of a man falsely accused who is being goaded by the killer into doing their bidding. The tension and stakes are high to the very end and there is a nice philosophical undertone to whole thing.
