Roquentin starts back toward the library, passing a man in a cape that he has seen twice earlier today. As Roquentin passes, the man in the cape starts smiling, and Roquentin stops to observe. The man stands up and starts to walk toward a little girl, who stares back at him without surprise as he starts to take hold of his cloak. Suddenly, though, the man sees Roquentin, and the girl runs away. Roquentin only warns the man that “a great menace weighs over the city” and leaves. Back at the reading room, the Corsican guard ushers reluctant patrons out of the library at closing time. Roquentin is loath to go outside, but when he does, he finds that it’s raining and the fog is gone.
The man in the cape seems like just another relatively insignificant part of Roquentin’s surroundings, until he isn’t. In reality, Bouville (and by extension, the world) is full of people who are troubled or unstable, like both Roquentin and the man in the cape. Roquentin notes pedophilia and sexual violence as if part of the landscape of Bouville several times, and this is one of those instances: the man in the cape intends to flash the little girl. The little girl’s initially challenging gaze might be read in two different ways: first, it might suggest that she’s so young and innocent that she has no idea what the man intends to do. It could also suggest (in Roquentin’s subjective understanding) she’s a tiny bit complicit in his bad behavior. Given the sympathy toward sex offenders that Roquentin demonstrates throughout parts of the remainder of the novel, both interpretations seem possible. The menace that Roquentin refers to is similarly ambiguous, but it might well refer to the fog that still lingers over the city. Speaking in such a veiled way, Roquentin seems just as crazy as the flasher, suggesting their shared nonconformity.
