Detective Comics #1072

Kelley Jones Cardstock Variant Cover

Batman arrives at the new Orgham grounds (which used to be the ruins of Arkham Asylum) to investigate what the Orghams have been hiding directly underneath the land that ties Gotham to the family centuries back...including the existence of Batman. Then, in the backup, Gordon investigates the reason Sorrow can't be near Batman...and they find out the difficult way.
