Looking for extra reasons to tie up in Mystic while cruising this season? In addition to the ghost of Ernie in New London, there’s also the ghost of 7-year-old Ada Clift in Mystic. She was the niece of Capt. Daniel Packer, who erected the Captain Daniel Packer Inne on the Mystic River in 1756. Little Ada died of scarlet fever, right there in the building, and her ghost is known to play in the restaurant’s stairwell. Though guests tend to notice Ada most often, employees say Packer himself still roams around the back rooms, too.
