Lady de Winter (Karin Field) is one of the main antagonists of erotic horror "Les dèmons" (1973), directed by Jesùs Franco.
She is a sadistic and cruel noblewoman who in the past had had an old witch condemned to the stake.
She will be killed with a supernatural "kiss of death" (through cunnilingus) by thr witch's daughter Margaret (Britt Nichols) while making love with her; her body turns into a skeleton after her death.
