Im guessing the HellFire Club? Which I just read Fox is developing as a series out of, http://www.slashfilm.com/x-men-hellfire-club-premiere/

They even have comic book covers for advertisement (I assume) that look like old Marvel covers from the 80s!.

Marvel should try and get that copyright nailed down. Now that Department H has its been mentioned in Agents of Shield. You cant have sex clubs or whatever using the same name. crazy.

If you google images: Department H....you get some "Interesting" images.
