Una Farfalla Con le Ali Insanguinate - 1971 - 6/10
AKA - Bloodstained Butterfly

While two children play hide n seek, the young woman, stabbed repeatedly, tumbles down the hill.
Police arrive and begin gathering clues about her murder.
A suspect was observed, recognized. There is evidence.
In court, the case is all but open and shut.
Except, the accused has a well prepared, calculating attorney.
Though under the Giallo umbrella, this lacks the garish colors, high style, and general overload.
The first half is police procedural and courthouse drama.
Moreover, the narrative makes sense.
Excellent thriller / mystery with, to me, a dash of Giallo.
