Macchie solari (1975), or Sun Spots, is a
  giallo that has been 
  variously called Autopsy, The Magician, Sun Spots, Tarot, Tension and The 
  Victim. The title this time around is Autopsy, which is a heinous bit of 
  exploitation which, when coupled with a specially edited trailer, would lead 
  you to believe this is a horror film having to do with re-animated corpses on 
  a killing spree. While the opening scene features an autopsy and several 
  suicides, the morgue and what goes on there are only tangential to the plot.
  
  Mimsy Farmer plays an intern in forensic pathology. She's working on a 
  method to distinguish real suicides from murders made to look like suicides. 
  She has a busy night, due to a large number of suicides, which reporters try 
  to blame on increased sun spot activity, hence the original Italian title. She 
  begins to hallucinate that the corpses are coming back to life. 
  Definitely time to go home. 
  In her building she runs into her upstairs neighbor. Imagine her surprise 
  the next day when the woman turns up at the morgue. Not only that, but she 
  strongly suspects the neighbor's death to be a murder made to look like 
  suicide. Together with a flaky father, her father's ex girlfriend, a priest 
  and her own photographer boyfriend, she tries to unravel the mystery.
  Like most gialli, the scriptwriters don't include enough real clues to 
  allow viewers to solve the mystery, but once the solution to the puzzle has 
  been revealed, all the pieces fit. The new region one release marks the first 
  time this film has been available uncut in North America, and there is a lot 
  of nudity to savor in a very nice transfer, backed by a musical score from the 
  omnipresent Ennio Morricone. You have a choice of Italian with English 
  subtitles or dubbed English,
  
          
          
          
          
          
          
                If you are not familiar with our grading system, you need to 
                read the 
          explanation, because the grading is not linear. For example, by 
                our definition, a 
                C is solid and a C+ is a VERY good movie. There are very few Bs 
                and As. Based on our descriptive system, this film is a:
                
                C
                A solid, competent giallo.
