You're now back in London. Walk off

You're now back in London. Walk off the docks and towards the "Mangled Mermaid." It's a one way path to the establishment. You cannot get in through the front door, so walk around the right side of the building. You'll hear a bit of dialogue between a lady and a guy. After the talk, go around the back and enter. Walk up the stairs to activate a short cut scene.
