A Marriage in Strain
An unhappy household
Miles Archer and Iva Archer have a troubled marriage, and Iva has sought a divorce. Her dissatisfaction gives the police a plausible motive to investigate.

The Secret Affair

Hidden intimacy
Iva has been involved with Sam Spade, her husband’s business partner. Their relationship is not a public matter until the murder draws attention to it.

A direct accusation

Jealousy at the Door

Jealousy at the Door
A confrontation interrupted
Iva waits outside Spade’s building and sees him with Brigid O’Shaughnessy. She demands to know who the other woman is and asks to come inside.
A boundary imposed
Spade refuses, even as Iva protests that their affair gave her a claim on him. The episode shows him distancing himself from a relationship he helped create.

At the office, Effie Perine tells Spade that Iva is waiting to see him. Spade accepts the news with a visible shiver.
