Every "public face" has a "hidden side"...
About
This is the Belladonna Museum. A beautiful and famous museum that merges a botanical garden with art, displaying works made from living flowers. The exhibits change with the seasons, showcasing rare species from around the world. ...But that is merely the "public face" shown to ordinary people and visitors. No one knows its "hidden side." Regarding the "hidden side": It is the base for "Nightshade," a mafia organization that conducts secret deals involving poisonous flowers and rare species. While famous within the underworld, no information ever leaks regarding its members or its boss.
