Plot Summary: Warning: wikipedia contains spoilers

In 1906 Chester Gillette was convicted of killing his ex-girlfriend, Grace Brown, at Big Moose Lake in the Adirondacks in upstate New York. The murder trial drew international attention as Brown's love letters to Gillette were read in court. Theodore Dreiser saved newspaper clippings about the case for some 15 years before writing his novel. Clyde Griffiths was based on Chester Gillette, right down to the same initials.

Clyde's downfall begins when he takes a job as a bell-boy at a local hotel. The boys he meets are much more liberal than he, and they introduce Clyde to the world of alcohol and prostitution. Clyde enjoys his new lifestyle, and does everything in his power to win the affections of the flirtatious Hortense Briggs. But Clyde's life is forever changed when a stolen car he is travelling in with friend's kills a young child. Clyde is forced to flee Kansas City, and after a brief stay in Chicago, he reestablishes himself at the collar factory of his uncle in Lycurgus, New York.

Although Clyde vows not to give in to women in the way that caused his Kansas City downfall, he quickly succumbs to the charms of Roberta Alden, a poor girl working under him at the factory. While Clyde initially feels fulfilled by Roberta, his ambition forces him to realize that he could never marry her. He dreams of the aristocratic Sondra Finchley, the daughter of a wealthy Lycurgus man, and a family friend of his uncle's. As developments between him and Sondra begin to look promising , Roberta discovers that she is pregnant.

Trying unsuccessfully to secure an abortion of the child, Clyde procrastinates the decision while his relationship with Sondra continues to mature. As he realizes that he has a wonderful opportunity to marry into such an aristocratic family, Clyde hatches a diabolic scheme to drown Roberta in a manner that seems accidental.

Despite initial doubts, Clyde carries through with his plan, drowning Roberta in the Finger Lakes region of New York. The case is relatively simple for the local authorities, and Clyde is found guilty and sentenced to death. The jailhouse scenes and the correspondence between Clyde and his mother stand out as an exemplar of pathos in modern literature.
