Alexander, Doris, Eugene O'Neill's Creative Struggle: The Decisive Decade, 1924—1933, Pennsylvania State University Press, 1992, pp. 103—28.

Floyd, Virginia, The Plays of Eugene O'Neill: A New Assessment, Ungar, 1987, pp. 334—52.

Floyd traces the growth of the play from O'Neill's early notes and scenarios, and analyzes it act by act. She argues that the plot is weak, and the strength of the play lies in the characterization.

Mannheim, Michael, Eugene O'Neill's New Language of Kinship, Syracuse University Press, 1982, pp. 60—71.

Mannheim emphasizes the autobiographical elements in the play, which represent O'Neill's attempts to escape the pain associated with the deaths of many close to him, and his discovery of his mother's drug addiction.
