Marlowe goes back to the scene of the crime, but when he enters Geiger's house, guess who's there. Carmen. Of course.
Marlowe asks Carmen who killed Geiger, and when he suggests Joe Brody, she reacts strongly and affirms that yes it was Joe. But when Marlowe tries to pry more information from her, she plays dumb and goes back to her usual giggling and flirting.
Marlowe tells her that if she had come to look for the film negatives, they weren't there. Carmen says she wants to leave, but they hear a car coming up the driveway, and she freaks out.
The door swings open, and a man dressed all in gray walks through.
