Olo I too am kinda confused on this. Everything was easy up until the lockbox part.
I spoke with the drunk guy and he gave me the layout of the room. I waited till morning and followed her into her room, she tells the guard to leave, and she says it it's uncomfortable and then walks onto the balcony and mentions the wine.
I did all manner of things from /look to /inspect lockbox. It says "There's nothing that indicates there's anything of interest inside." And /take necklace results in "There's nothing of interest for you."
other MUD commands like /pry, /open, /insert [while holding a lock pick in my cursor] do not seem to get any feedback.
