We join Mr. Bradley Headstone, who's been following Eugene Wrayburn in the hope that Eugene will lead him to Lizzie Hexam. Finally, he goes to Eugene's place of work and asks for him.
While he's waiting outside, another guy comes up to the door and asks for Mr. Mortimer Lightwood. The man is none other than Riderhood, and he and Headstone quickly realize they have something in common. They both hate Eugene Wrayburn.
Headstone realizes that he might be able to use Riderhood to his advantage. Out of nowhere, he offers Riderhood five shillings, although he doesn't say right away what he wants for it.
Headstone asks Riderhood whether he's ever seen Eugene Wrayburn being "friendly" with Lizzie Hexam, and Riderhood confirms that he has. Now Headstone's jealousy looks like it's going to boil over.
Headstone says he'll come visit Riderhood soon at the place he works, which is now a river lock.
