"I'll take you straight home," Penny promised. "I don't suppose I need to mention it, but I think we shouldn't tell anyone about what we discovered tonight. At least not until the police have been notified."
"Of course not," Susan agreed instantly. "Why don't you have your father make the report for us?"
"I'd like to handle it that way, if you don't mind," Penny said eagerly.
"Then let's leave it that way. Aside from Mr. Nichols we'll not tell a soul about our discovery tonight."
A few minutes later the girls took leave of each other. Penny continued alone toward her own home.
Turning a corner in one of the outlying neighborhood business sections, she noticed a girl in blue hurrying along the street. Recognizing Betty Davis, Penny halted her roadster at the curbing.
The girl did not notice for she had paused to stare into the window of a café. A group of young men could be seen within, laughing and talking.
It was not the type of place frequented by women, and Penny was astonished when the girl started to open the door. But with her hand on the knob, Betty Davis seemed to reconsider, for she turned and walked rapidly away.
Penny drew alongside in her roadster.
"Going my way?" she asked cheerfully. "I'll be glad to give you a lift."
