Lisa Whiting says she has seen the little girl. This was about seven years ago, when Whiting was standing behind Stone's Public House in Ashland, around the time she started working there. She happened to glance up and see a wee ghost looking down from a second-floor window."She's very clear -- crystal-clear," said Whiting, describing the apparition as having long dark hair and wearing a white dress. "It's not like she's hazy. She looks like she's real, like she's standing up there."Apparently she's still around: Last month a customer sitting out on the patio asked who the little girl was in the window. The answer made her bolt from her seat and run inside.A source of reported ghost sightings for decades, Stone's Public House, now a bar and restaurant, was recently the subject of an otherworldly investigation, the results of which will be revealed next month on a new Sci-Fi Channel series, "Ghost Hunters."Aside from the ghosts themselves, the stars of the show are a group of diehard spirit-seekers from the Atlantic Paranormal Society, based in Rhode Island. The group's motto: "We scare them back."They visited Stone's in July and set up an array of equipment straight out of the movie "Ghostbusters," including an electromagnetic field detector and an infrared camera.The investigators won't talk about what they found, but they promise the episode featuring the old Ashland landmark will be worth watching."I'll just say it was a very good show," said Brian Harnois, head of the society's technical department. "It was one of our best investigations so far. It's a little freaky."
