In September of 1973, a year before his tenure at Dalton ended, Barr published Space Relations.
The book is highly unsettling and depicts the rape of enslaved people, especially teenage girls, and other coercive sex acts for the dual purposes of entertainment and controlled procreation. Barr resigned from his position as headmaster in June 1974 due to disagreements with trustees “over budget priorities and his disciplinarian approach to substance abuse,” according to his obituary in The New York Times.
"Craig ends up enslaved by Lady Morgan and falls in love with her. Though he is set up to be a kind of anti-slavery hero, he does not mind that she is a flamboyant sadist, and even enjoys participating in her demand to sexually assault an enslaved teenager at a clinic used to “breed” enslaved people."
