Screams heard coming from an upstairs window at the historic Black House on W. Main Street might have frightened some people Saturday, but others were enthralled by the scene unfolding. The screams were part of a play, “Murder Mystery at the Black House,” held as a way to raise money for upkeep and routine maintenance of the house.Black House representative Jeanette Lowery said there was a large turnout for their mystery performance held Saturday. She said over 200 adults and several children toured the house and interacted with characters.“Everyone seemed to enjoy it,” said Lowery.
