this already happened, I already did all this part, but after going to the second floor of the tavern I went to see Audrey for the first time, after that it says that I have to deal with the spy and find her room in the tavern, But when I go In the tavern I don't see an option to go to a room, I get stuck in that part without knowing what to do
Which version of the game are you playing? In Previously versions, while completing this quest, you could accidentally leave the second floor of the tavern before finding the room.
But in the new version, this should have been fixed.
You needed to click on all the doors on the second floor of the tavern: read 2 dialogues, watch the scene with Lillian, and then you would automatically start a dialogue that would take you to the Spy's room.
Try loading an earlier save, or, unfortunately, start a new game.
