Private eye Sam Spade and his partner Miles Archer are approached by Miss Wonderly to follow a man, Floyd Thursby, who allegedly ran off with her younger sister. The two accept the assignment because the money is good, but Spade also implies that the woman looks like trouble, though she projects wholesome innocence.
That night, Detective Tom Polhaus informs Spade that Archer has been shot and killed while tailing Thursby. Even later that night, two officers visit Spade at his apartment and inquire about Spade's whereabouts in the last few hours. Spade asks what the visit is really about. The officers say that Thursby was also killed and that Spade is a suspect, since Thursby likely killed Archer. They have no evidence against Spade at the moment, but tell him that they will be conducting an investigation into the matter.
The next day, Spade gets a visit from Archer's wife, with whom he has been having an affair. The widow asks Spade if he killed Miles so that they could be together. Spade dismisses her and tells her to leave, and coldly orders his secretary Effie to remove all of Archer's belongings from the office. He then goes to a new address left in a note from his client, whose name he learns is Brigid O'Shaughnessy. He also finds out that Brigid never had a sister, and Thursby was her acquaintance who had betrayed her.
