He subsequently worked as a reporter and wrote short stories, historical fiction, and novels for adults and adolescents.

He also wrote the script for the film An Ancient Tale: When the Sun Was a God and the historical series Royal Dreams, which he later published in book form.

He also wrote belletristic biographies, among them I, Michel de Montaigne (1978); The Clown, a Great Man (1998), a comprehensive sketch of the character and activities of Tadeusz Boy-Zelenski; and My Friend the King (2003), about Stanisław August Poniatowski.
