The First Rule of the Cabaret

Exploration Stage: Shooting Star Cabaret
From: Sophia
Description: Dearie, let's pick a symbolic item for each rule of the Cabaret. The first rule says: "Bring flowers to the Cabaret, not weapons!" A visitor once interrupted my performance witha gunshot. When he left the Cabaret, he disappeared, and I received an apology note and a gun in some roses. Let's find it!
Completed: Sugar, this gun in roses will be an excellent symbol for the first rule of the Cabaret. I hope no one else dares bring weapons to this place.
