 What do Lois and Lorraine have in common?
An Unsolved Mystery “Tell Judy about it,” begged Lois. We’re both Farringdon-Petts and should be loyal to each other. “You’re right, Lorraine,” announced Judy, coming in to serve dessert to the two friends she had invited for lunch at Peter’s suggestion. 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. “I know now that keeping that promise not to talk about the dam was a great big mistake and could have cost lives. 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. You’ve been chasing ghosts ever since I met you, and not one of them did you fail to explain in some sensible, logical fashion.” They left me a lot of unsolved mysteries along with this house. She wasn’t in the mood for digging up old mysteries, but Lois and Lorraine insisted. It all began, she finally told them, the summer before they met. And so it was that he spent the summer Judy was remembering in Farringdon where the Farringdon-Petts had their turreted mansion, while she had to suffer the heat and loneliness of Dry Brook Hollow. Her thoughts were what had made it so hard, she confessed now as she reviewed everything that had happened. Your grandmother never throws anything away. She had seen her father’s tired eyes and had realized that a busy doctor needed a vacation much more than a schoolgirl who had too little to do. 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 . “A whole parade of ghosts,” Lois would be telling her, “and you solved everything.” 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.
