Investigación sobre un ciudadano libre de toda sospecha

A chief of detectives (Gian Maria Volontè), homicide section, kills his mistress (Florinda Bolkan) and deliberately leaves clues to prove his own responsibility for the crime.

I absolutely loved this film. It is part crime thriller, part detective story, and a bit of political corruption. Being Italian and having an Italian sensibility, it reminded me more than a little bit of the giallo film genre. But yet, it was distinct. The giallo is in some ways the precursor to the slasher, and this was not that sort of film -- not gory and the killer is not a masked and gloved man.

What really stands out is the score from Ennio Morricone. He has made many scores over the years and without exception they have been quite good. Is he the best composer of the 20th century? Maybe. And I would daresay this is among his very best, easily in the top three. The score alone makes the film worth watching.
