Every year visitors flock to Maine’s Fort Knox near the mouth of the Penobscot River. They are drawn by the thousands for its glimpse into Maine’s military past, but also for it's haunted aspects. The fort was catapulted to national attention when the prime-time TV show Ghost Hunters filmed an episode there. Since no shots were ever fired from the fort, who might the ghost or ghosts be? Now, Gardner Walsh delves into the creepy nature of the fort to find the answer. She explores the history of the fort and some of the Indian legends of the area from before the fort was built; provides interviews of staff and eye-witness accounts of ghost sightings at the fort; and she offers a fun look at how the fort makes the most of its attention by hosting its annual Fright at the Fort—called the "best Halloween experience in Maine”—and the summer Paranormal Faire. Woven throughout, Walsh recounts her own haunted adventure when she spent a night locked in the fort with the East Coast Ghost Trackers.
