Reluctantly, Penny raised the window glass. Before she could drive on, another car pulled up not far from the tower. The driver, a man in an overcoat, swung open the door as if to alight. However, observing Penny’s car parked close by, he seemed to change his mind. Keeping his head lowered so that his face was shadowed, he drove away.
“Who was that man?” Penny demanded suspiciously.
“I’m afraid I neglected to inquire,” Louise retorted. “So careless of me!”
“Whoever he was, he intended to enter the tower! When he saw us here, he became nervous and drove away!”
“Oh, Penny, you’re the limit.”
“Maybe I am, but I know what I think. The striking of the clock was a signal for some sort of meeting at the tower!”
“A board of directors confab perhaps?” teased Louise.
“Listen!” said Penny, ignoring the jibes. “I want to park the car on a side street, and then come back here afoot. Something is up and I mean to find out about it!”
“Oh, Penny,” Louise sighed. “If I don’t get home Mother never will allow me to go anywhere with you again. Don’t you realize what time it is?”
“Thirteen o’clock!” Penny chuckled. “It may never be that again, so I must strike while the clock strikes, so to speak. How about it?”
