You find a record kept by one of the society's historians pertaining to the "dreadful events" surrounding the closing of an old theatre in Arkham, the Cedar Playhouse. Though there is no explicit mention of The King in Yellow, you believe you are on the right track. The historian's notes are cut short, and there is a faded, handwritten page clipped to the final entry. This matter is too ghastly for the public eye. I am placing the remainder of this record in the hidden library. All further inquiries should be done away from prying eyes, for this is a dangerous matter, and not one to be researched lightly.

As you rummage through a desk drawer, you are startled when you hear a voice behind you. "Excuse me! Can I help you?" You are relived to find the voice belonging to a thin, elderly man wearing wide-rimmed glasses - a member of the Historical Society, no doubt. You explain to him that you are searching for a hidden library somewhere in the manor, though you purposely leave out why. He introduces himself as Mr. Peabody, the Historical Society's curator. "I'll help you find what you are looking for," he explains, "but only if you tell me what this is all about once we get there." You hope it doesn't come to that.

As you study the hidden library, you find a few pieces of information that stand out. As with the recent production, the previous performance of The King in Yellow came to Arkham from overseas, and was performed by a French acting troupe. You don't recognize any of the cast members' names, and of course the actor who played the role of the Stranger is anonymous. However, it seems that a member of the Historical Society has done some of your work for you; there are several old newspaper clippings gathered together along with information about the play. Headlines include: Cedar Playhouse Closes Due To Fire, Experts Baffled Over Freak Floods, and the like. Hidden amongst this information, you also find a strange object - A clasp of onyx with an alien inscription.
