Terence Sellers (1952–2016), also known as Mistress Angel Stern, was a New York-based writer and dominatrix involved in the New York Downtown Arts Scene.
Sellers kept daily journals, maintained correspondence with friends, family and colleagues, wrote short stories and worked on several manuscripts.
While her work as a professional dominatrix and her fascination with violence, self-punishment, the occult, and psychoanalysis shaped much of her writing, her literary influences include Baudelaire, Dostoevsky, and the French surrealists.
Sellers' novel The Correct Sadist: The Memoirs of Angel Stern is written as a collection of short "case studies" relating to themes of sexual dominance and submission, bondage and discipline, and fetishism.
Originally published by iKoo-Buchverlg in Berlin in 1981 as Der korrekte Sadismus, Sellers self-published the work in English under Vitriol Publications in 1983.
