question:  Why did Lois decide to turn the car around?
context: “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. “Before I met you,” Judy said, thinking back, “there were plenty of them I couldn’t explain. It all began, she finally told them, the summer before they met. 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. 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.” 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. If anyone had told the freckled-faced, pigtailed girl that she would one day marry Peter Dobbs, she would have laughed in their faces. And she went on to tell them how, the very next day, her grandparents had taken her to a fountain exactly like the one in the picture. It was in the center of a deep, circular pool with steps leading up to it. Dora Scott had been her best friend in Roulsville, but she had moved away.
