The Mulatto is published as a book. The play is, with its depiction of the pariah and sexuality to be found within the tension between the social spheres, from lower to upper levels, a dramatic counterpart to the novel O.T.
Swedish translation of O.T. is published under N.H. Thomson's Bibliothek af Den Nyaste Litteraturen (Stockholm).
