Darting to the corridor door, Penny jerked it open. No one was in sight. However, at the end of the deserted hall, she saw the elevator cage moving slowly downward.

“I’ll get that fellow yet!” she thought grimly.

Taking the hall at a run, she plunged down the stairway two steps at a time. Breathless but triumphant, she reached the lower corridor just as the cage stopped with a jerk.

Harley Schirr stepped out, closing the grilled door behind him.

“Fancy meeting you here!” said Penny, her eyes flashing. “What were you doing in my father’s office?”

Schirr regarded her coolly. Without answering, he tried to brush past her.

“You were looking for something in Dad’s desk!” Penny accused, blocking the way. “I know how you got in too! Through the hall entrance. You’re such a professional snooper you probably have a skeleton key that unlocks half the doors in the building!”

“I’ve had about enough of your insolence!” Schirr retorted. “There’s no law which says I can’t come to this plant. And speaking of law, I may sue you for libel.”

“What a laugh.”

“You’ll not be laughing in a few days, Miss Parker! Oh, no! I’ve hired a lawyer, and we’re preparing our case. You’ve insulted me, humiliated me in the eyes of my fellow newspapermen, but you’ll have to pay. And pay handsomely!”
