Penny hastily climbed out of the cab, making an offhand apology for her presence.

"Okay Miss," the truck driver said, "seein' as you're a gal. But if you had been a man, I would have taken a fall out of ya. It's a crime that a man can't go for help without having some strange sister cuddle down in his cab."

The trucker's loud, gruff voice had attracted the attention of the man in the parked automobile. He stepped from his car and came toward the couple.

"What's the idea of abusing a helpless young girl?" he asked.

Penny recognized the voice, and resisted an impulse to turn her head. She knew that the newcomer was Hanley Cron. He had come to call upon Mrs. Dillon. That was plain. She must not let him discover that she was watching the house. Quickly, before either of the men were aware of her intention, she darted behind the truck and fled down the street.

A Puzzling Letter

Rounding the corner at the end of the street, Penny paused to catch her breath. It had been foolish to run away. She realized that now. But she had acted impulsively, without thinking.

She thought hopefully that Hanley Cron might not have recognized her. She was certain he had not seen her face.
