“What’s the matter?” she asked in surprise.
“Oh, Doris,” Kitty whispered tensely. “I was just on my way to find you! I think I’ve discovered the source of those strange sounds that have been disturbing us at night!”

“What are you talking about, Kitty?”
“Come, I’ll show you. Follow me and don’t make any noise.”
