Outside of the Asylum (A Hitchhikers Guide to the Galaxy Tribute)

You've hitchhiked across the galaxy to Earth to hire Detective Dirk Gently for a case, but he's been locked in an asylum by Wonko the Sane. Dirk is waiting for you by the front door, but it will be up to you to get it open. This room is an homage to Douglas Adams and his Hitchhiker's Guide to the Galaxy series (as well a reference or two to his Dirk Gently series). No outside knowledge is required, but it will likely be more enjoyable for those who know the references. I don't believe anything in here is a spoiler. It's not really the kind of book you can spoil.
