Out in rural Adams County, there are quite a few abandoned houses. Thought that this site deserved a cache. You do not need to approach the house itself. You are seeking a micro. Permission has been granted to seek here--however, use stealth at this location due to its deserted character, since you may appear suspicious to local drivers.
The title of the cache is in reference to a Sherlock Holmes short story, "The Empty House." In it, Holmes reappears in London three years after faking his death at the Reichenbach Falls, during which struggle his arch-enemy Moriarty was killed. He is then able to capture Moriarty's lieutenant, Moran, when the shooter arrives at an empty house across from 221B Baker Street. It has been most recently referenced in the BBC Sherlock series as "The Empty Hearse," in which Holmes also returns to London.
