French police on a training mission in Paris’ vast underground network of sewers, tunnels and catacombs stumbled upon an underground lair, complete with a cinema, a fully stocked bar, and a lounge. The entire place was wired for electricity and telephones. When police returned a couple days later with utility employees to trace the power and phone lines, they discovered the place had been cleaned out and the power lines cut; the whole place was abandoned. A note was found lying in the middle of the floor: “Do not,” it said, “try to find us.”
Ooh, they stumbled on some sort of secret society, a la The Da Vinci Code or something. The poor Rosicrucians had to go find a new playhouse.
