Librivox: Dorothy Dale's Camping Days by Penrose, Margaret

Summary: So the parties separated and then Dorothy was free to leave her hiding place. She longed to tell her friends the strange story, but she knew that the finding of Tavia was the one and only thing to be thought of just then. "Are you sure that this is the direction in which the boys went?" asked Nat, with something like a sigh. Dorothy looked over the rough woodland. "No," she said, "there was a swamp, for I distinctly remember that they picked their way through tall grass, and about here the grass is actually dried up." (Extract from Chapter 26)
