Where is the medium?

Exploration Stage: Santa's Workshop
From: Detective
Description: Don Juan was unnecessarily rude to women. I'm afraid I'll scare Juliette away if I behave in such a manner. Maybe I can soften his influence somehow. Let's ask the medium for advice, maybe she knows something. Martha isn't here, that's strange. But she would never go without leaving some kind of a note for us. Let's look for it.
Completed: Strange, Martha's nowhere to be seen, but she left a note: "Gone to the Red Rose". Does she know how to enter the Cafe? I thought no one knew but you. Let's go!
