Communing In Darkness
Time was that everybody who was anybody went to seances. Time was that there was a living to made out of being a medium. Some of them were fakes, sure - But some of them were for real, and could put you in touch with the dead. For many rich people, mediums were a necessity. Who else would provide a link with family long gone? In the occult-obsessed 1920s it hit fever pitch, and both the good and the bad mediums thrived in an atmosphere of appreciation. Six people gather around a table. They join hands. The call goes out "Is there anybody there?" Tonight, someone is definitely there. And they want to talk.
PS:
2-3 weitere Szenarien fallen mir auch noch ein, allerdings nicht mehr der Titel oder wo. Eines müsste sofern ich mich Richtig erinnere in einem der Lovecraft County Bände sein, vermutlich Arkham.
