Just finished reading "Devil's Puzzle" by Leilac Leamas, a thrilling mix of romance and intense erotica set across Italy, Spain, and Portugal. A particularly unique scene in Paris caught my attention, where the protagonist infiltrates an elite, secretive club, which turns out to resemble a high-end swinger's club as part of an espionage plot. The book portrays all its locations with striking realism. After googling, I found that all mentioned places realistically exist as described, except for this specific club. I'm planning a trip to Paris in June and am keen on discovering if this club is real. The idea of exploring such a unique setting firsthand is intriguing. I've looked into Castel Events and Killing Kittens, but neither seems to match the book's depiction. Does anyone know if this club actually exists or can suggest anything similar?
