Polite published her second book Sister X and the Victims of Foul Play, about the investigation into the death of a black nightclub dancer in Paris, in 1975.
[citation needed] Polite joined the University at Buffalo in 1971, where she taught creative writing, African American history and literature until her retirement in 2000.
She became tenured and served on committees, as well as chairing the American Studies Department for a short while.
[citation needed] Her classroom assignments often centered on books such as The African Origin of Civilization by Cheikh Anta Diop, Stolen Legacy by George G.M.
In her tenure at the university, she only used two teaching assistants (John Ransom and Kyle Phoenix (née Brian Kyle Doyle) both later published authors), feeling that their personal abilities, writing interests and knowledge were sufficient for her classroom needs.
