The protagonist of this work, described as "happy and dauntless and sanguine" has constructed a edifice girdled by a "strong and lofty wall".  That edifice in this story houses an ebony clock so loud that the orchestra stops when it sounds, and at the striking of midnight enters a mysterious guest with bloodspots on his face and wearing a funeral shroud.   The story ends in the black and red room with everyone dying, including the host of the party.  For 10 points, name this short story by Edgar Allen Poe about Prince Prospero and the titular colorful disease.
