A tough police inspector (Paul Naschy) tries to find the killer who is stalking the streets of Milan, leaving a fake dragonfly on each body. As the inquiry drags on, his wife (Erika Blanc) does some sleuthing, too. Overall the movie, originally titled Una libélula para cada muerto, is rather dull, albeit watchable.

  Mildly recommended at best. Otto judiciously thinks this movie is OK, but not great.

Movie 347 for 2021.
