Inspector Franz Bulon (Sir John Mills) is a veteran Hamburg police detective in charge of a drugs investigation, but is finding it hard to break the case, his mind is elsewhere
on his beautiful young wife Lisa (Luciana Paluzzi) that is, a former criminal herself, though never convicted, a fact that Bulon's colleagues never let him forget, Bulon's problem is that he suspects Lisa of cheating on him a fact he can't quite prove, until one day he thinks he has caught her out and sets about hiring a local killer Max Lindt,(Robert Hoffman) the man behind the killings of witnesses in his drugs investigation, to kill his wife in return for him hiding the evidence building against him.
A Black Veil for Lisa deviates from normal giallo practice by telling us who the killer is, much like Luigi Cozzi's The Killer must kill again. The story is driven by the man (Bulov) who hires the killer to do his dirty work, as a result, Dallamano replaces the lack of mystery with some decent character development, Mills is excellent and portrays well Bulov's obsessiveness with his wife's cheating, which ultimately leads to his own self destruction.
