The Perfume of the Lady in Black (Italian: Il profumo della signora in nero) is a 1974 giallo film directed by Francesco Barilli.

Accompanied by her boyfriend Roberto, she visits some Afro-Italian friends including Andy, a university professor, who explains that witchcraft, black magic and human sacrifice are all commonplace in Africa.

He also reveals that in his country, there are still cults that target unknowing victims who are driven insane and ultimately killed.

After attending the funeral, Silvia comes home and finds that Francesca's cremated remains have been left in her apartment.

Silvia's hallucinations increase as her younger self convinces her that everyone else is evil and begins to command her to do things while wearing Marta's black dress.

She then arranges Roberto's body with those of Mr. Rossetti and Nicola around a dining table in a mock-up tea party.

Silvia's naked corpse is laid out on a table in a dark chamber in the same abandoned tunnel system seen earlier.

A large group of cultists dressed in blue lab coats—including Roberto, Nicola and Mr. Rossetti, who are all alive—surrounds Silvia's body.
