An authoritative, collated version of the Mansfield script charts the evolution of his play through its Boston, New York, and London productions. Biographical information is presented for Mansfield, Thomas Russell Sullivan, who worked with Mansfield to adapt the novel into a play, and Stevenson. Special attention is given to American theater and popular entertainment during the late nineteenth century, and to the Jack the Ripper murders, which led to the closing of Mansfield’s London production. Appendices include competing scripts staged by Daniel Bandmann and H.B. Irving, as well as reviews of the various productions, transcripts of Mansfield interviews, and excerpts from early biographies of Richard Mansfield.
