The novel Dawn of Reckoning, was first published in London in 1925. In 1932, it was published in New York under the title Rage in Heaven. In 1941, it was adapted in the movie 'A Rage in Heaven', a psychological thriller about the destructive power of jealousy which was directed by W. S. Van.

In this story, Phillip Monrell and his former college roommate Ward Andrews arrive at the Monrell home, where they meet Phillip's mother's secretary Stella Bergen. They are both strongly attracted to her but she ends up marrying the idle Phillip. Phillip is put in charge of the family steel mill, but is not suited for the job. He begins to exhibit signs of mental illness, particularly abnormal jealousy of any competition for his wife's affections. Despite this, he hires Ward to be the chief engineer at the mill. Eventually, Phillip's paranoid suspicion that Ward and Stella love each other drives him to try to kill his rival at work. Ward confronts him and quits. Stella, convinced that her husband is insane, leaves him and meets Ward. Phillip phones them and promises to grant her a divorce if Ward will talk with him in person. Despite Stella's misgivings, Ward agrees to see him. However, Phillip provokes a loud argument and Ward leaves. Afterwards, the madman kills himself, carefully framing Ward for the crime. Ward is arrested, convicted of murder and sentenced to be executed. A frantic Stella is unable to convince anyone of his innocence. The day before the execution, she is visited by Dr. Rameau, a psychiatrist who had been treating Phillip. He is convinced that Phillip committed suicide and that he would have left some message bragging about it. They go to the Monrell mansion and start searching. Mrs. Monrell reveals that her son kept diaries; then, Clark, the butler, recalls that he mailed a package to Paris. They take a flight to France and find the book, which saves Ward from execution.
