The Earl sends Richard and Door in search of the Angelus, which could provide the key to the mystery of who murdered Door's family. Their search brings Richard back into London Above, where he meets a familiar face, even if no one there recognizes his.

Earl's Court erupts into total chaos at the presence of the Marquis, and he tells Door he'll meet back up with her at the next floating market. Door and Richard reach Islington via a piece of art showing at an exhibit Richard's fiance, Jessica, helped organize, narrowly escaping the clutches of Croup and Vandemar. After meeting with Old Bailey, de Carabas seeks out the two assassins.
