Headquarters of the Cellar Door Society

The Cellar Door Society was an organization of detectives in a holodeck program. Zero described them as "purveyors of puzzling puzzles, amateur sleuthing, and milquetoast mysteries." The Society was headquartered in a lighthouse.

The program involved the player(s) solving a mystery, which was revealed on a wax-sealed letter slipped through the Society headquarters' mail slot at the stroke of midnight on a grandfather clock. Once it was solved, the program ended and the arch would appear. Mysteries featured in the program included "The Case of the Biting Ghost", "The Case of the Lost Skeleton Key," and "The Case of the Phony Pharaoh".

Zero was fond of spending their recreational time on the USS Protostar in the Cellar Door Society program. In 2384, under the influence of the living construct, Hologram Janeway used elements of the program to trap the Protostar crew on the holodeck. (PRO: "Ghost in the Machine")
