Following his retirement, Girzone embarked on a second career as a full-time writer and speaker. He published his first novel, "Joshua", in 1983, which was the first of a whole series of books which had the premise of Jesus Christ returning to earth and living as an itinerant carpenter. After being rejected by all the publishing houses he had approached, he founded his own publishing company, Richelieu Court Publications, to release the novel. He carried boxes of the book in his trunk of his car, making modest sales at different locales.
