“I’m not sure anything is right about all this mystery,” was the answer, “but this is a chance we mustn’t miss. Come on.”
“But where are we going?” Belle queried.
“I can’t tell, but I think to the cave,” Cora answered. “Don’t be afraid. There’s no danger.”
Hardly had she spoken than a noise sounded behind them.
“Oh! what’s that?” cried Belle, rushing forward.
“It sounded like a door closing,” said Hazel.
She flashed her light back on the way they had come, and as she did so she cried:
“It was the door. It has swung shut, girls! We’re trapped!”
