“Where is the station thought to be located, Dad?”
“Oh, it moves nightly. The fellow obviously has a portable broadcasting outfit.”
“But isn’t the general locality known?”
Mr. Parker smiled as he knocked ashes from his cigar.
“Authorities seem to think that it may be somewhere near here. Sunset Beach has countless caves, you know.”
“Really?” The information excited Penny. “You never told me that before, Dad. And I suspect that you’re keeping a lot of other secrets from me too!”
“Sunset Beach’s caves are no secret. They’re part of the tourist attraction.”
“All the same you never mentioned them, Dad. I thought it was odd that you chose this place for a vacation. Now I’m beginning to catch on.”
Mr. Parker pretended not to understand.
“Isn’t it true that you came here to do a bit of investigation work?” Penny pursued the subject relentlessly.
