Character Role Analysis
Brigid
Brigid is a tricky character to assign a single role to because she's Spade's romantic interest, but she also turns out to be Archer's murderer. So she could also be seen as another major antagonist in the novel, especially considering how she lies a lot more than Gutman ever does. We discuss Brigid's double-sided nature in great detail in the "Character Analysis" section, so take a gander over there to read more about her.
