You know how it is. You’re in the market for a house (or idly speculating on the fantastical day when you’d actually be able to afford one) when your Zillow scrolling tour of some nondescript-looking fixer-upper comes to a horrified halt at the one photo indicating that the previous owners had some . . . secrets. Well, as Aaron Paul noted on his Thursday Late Show appearance from his recently purchased home in Los Feliz, California, when your price range is essentially peak-TV unlimited, the hidden features of your prospective abode escalate from the odd kitchen toilet or Bigfoot sighting to an entire, super-secret, Prohibition-era speakeasy, concealed behind a fake wall and a giant wall safe.
