Drunken Tramp.
There is a scene where the protagonist is driving to the home of Mrs. Buttle. There is a brief moment where we see a drunken bum, but he's like a giant in comparison to the car. I didn't really understand what was supposed to be happening in this scene. Is it suggesting that the bum is hallucinating this whole thing?
