DRCL midnight children, 6

In search of the Count's lair, Joe arrives in London with the shadow of Jack the Ripper as his only clue. As he hurtles through the cold, cobblestone streets, a colossal hexagon appears before him, seemingly floating above the city. Following in the footsteps of the Count, who lies in a coffin as large as the city itself, Joe doesn't hesitate to enter the mansion of death where he dwells. Pandora's box has been opened. What awaits him inside? Hope, or perhaps the abyss of despair?
