“But who do you suppose conceived such a plan?”
“I can’t answer that one,” Penny laughed. “But come on, let’s see if we aren’t approaching the exit.”
Eagerly they moved forward, guided by the streak of light. A minute later Penny who was in the lead, gave a joyous shout.
“We’ve come to the end of it! I can see trees!”
“Thank goodness,” Rosanna sighed in relief. “I was afraid we’d never get out alive.”
Penny parted the bushes which barred the exit and they peered out.
“You were right, Rosanna. We did travel toward the lake. We’re almost in it for that matter!”
The water came within a few yards of the entrance and during a storm the girls imagined that it must flood the lower passageway. Penny noticed a rowboat tied up in a clump of bushes.
“I suppose that’s how our ghost makes his quick get-away,” Penny remarked dryly.
“We might take a ride on the lake,” Rosanna proposed.
