"Solamente nero (internationally released as The Bloodstained Shadow, Bloodstained Shadow and Only Blackness) is a 1978 Italian giallo film directed by Antonio Bido. The film was referred as \"a fine example of a competent giallo, as it contains all of the requisite elements\". Paul Simpson wrote about the film: \"The pacing goes awry, but Bido uses the unusual setting well and the murders are memorably gory.\""@en . . . . .
