question:  Which mystical element didn't Judy claim to encounter?
context: An Unsolved Mystery “Tell Judy about it,” begged Lois. I met you when the whole valley below the big Roulsville dam was threatened by flood and you solved that—” “That,” declared Judy, “was my brother Horace, not me. Maybe you were mistaken about a thing or two before the flood, but what about the haunted house you moved into? You were the one who tracked down the ghosts in the attic and the cellar and goodness knows where all. There was one I used to call the spirit of the fountain, but what she was or how she spoke to me is more than I know. They left me a lot of unsolved mysteries along with this house. Her thoughts were what had made it so hard, she confessed now as she reviewed everything that had happened. Every summer Dr. Bolton and his wife relived it. And every summer Judy went to stay with her grandmother Smeed, who scolded and fussed and tried to pretend she wasn’t glad to have her. In another year she would have outgrown her childish resentment of her parents’ vacation or be grown up enough to ask them to let her have a vacation of her own. In another year she would be summering among the beautiful Thousand Islands and solving a mystery to be known as the Ghost Parade . She had no idea so many thrilling adventures awaited her. As Judy wiped it away she noticed that it had fallen on a picture of a fountain. The thrill of walking up to the door of the palatial Farringdon-Pett mansion was still ahead of her. On the lawn a fountain still caught and held rainbows like those she was to see on her honeymoon at Niagara Falls. She and Lorraine had listened to this much of what Judy was telling them without interruption. It was in the center of a deep, circular pool with steps leading up to it. I wasn’t thinking of anybody but me, Judy Bolton, and what I wanted.
