Arguing that the 1964 edition of Eugene O''Neill''s unfinished play More Stately Mansions, prepared after the playwright''s death, was missing a substantial amount of material that O''Neill intended for inclusion, Martha Bower here presents an entirely new edition of the play with this material--dialogue, character description, an entire scene, the epilogue, and large parts of other scenes--restored. Published to coincide with the centennial of O''Neill''s birth, it will stand as an important contribution to O''Neill scholarship.
