Delitti e profumi (also known as Crimes and Perfume) is a 1988 Italian giallo film directed by Vittorio De Sisti, based on a story entitled Scarlet by Bonadies and De Fornari, both of whom also worked on the screenplay.
After receiving some perfume as a gift from a mysterious admirer, Barbara is burnt to death when she walks under some warm halogen spotlights.
In order to discover what killed Barbara, Eddy decides to investigate together with Inspector Turroni.
Afterwards, a prostitute named Portia is murdered in a similar way and Eddy discovers the cause of their deaths... the perfume sent to each victim by the killer contains a highly flammable substance (benzopyrene-15).
The criminal is apparently getting revenge for a terrible accident that happened that summer at the camp.
