Whitman Chambers (1896-1968) was an American author known for his work in pulp fiction, particularly crime and mystery novels. Writing during the mid-20th century, Chambers created fast-paced, gritty stories often featuring hardboiled detectives, complex moral dilemmas, and seedy urban settings. His novels, such as The Night of Evil and Invasion*, exemplify the noir style that was popular during the era. Chambers also worked as a screenwriter in Hollywood, contributing to several film adaptations of his works and other crime dramas. His writing reflects the dark, suspenseful atmosphere of early American crime fiction.
