.. Raoul

Yeah, the kitchen is for personnel only. Maybe you should get rid of Raoul for a while so you can do your things in the kitchen.

Follow him for a while. Do you notice one thing he will do periodically?

He is visiting the pantry quite often. Pantry, that has doors.

You should lock Raoul into the pantry. Close the doors when he is in.

Lock him in with your trusty tool. ( Use the scythe on the pantry doors when they are closed and Raoul is in the pantry. )

And Glottis comes and drinks all the wine! How can he drink so much?

Now that the cask is empty...

You can use it to get into the wine cellar elevator.

Now, just find Charlie's money suitcase.
