Fenestra rattled the handle several times, and threw his body against the panel once or twice. Then she heard footsteps as he walked away.

“That’s only a trick to get me to come out,” thought Penny. “I won’t be stupid enough to fall into his trap. I’ll stay right here.”

Walking to the window, she gazed down. Cars were passing along the street. If she shouted for help someone might hear her. However, to explain her predicament would be rather awkward.

Penny’s gaze fell upon the telephone which had fallen from the desk to the floor. Picking it up, she dialed the number of her own house. Mrs. Weems answered.

“Hello,” said Penny cheerfully, “Dad hasn’t come home yet by any chance?”

“He’s just now driving into the garage,” the housekeeper replied. “I’ll call him.”

A moment later Penny heard her father’s voice at the other end of the wire.

“Dad,” she said, “I’m down at your office, sitting behind some barbed wire entanglements. I wish you’d get a policeman and see what you can do about rescuing me.”

“Is this one of your jokes?” Mr. Parker demanded.

Fearful that her father would hang up the receiver, Penny talked fast and to the point. Mr. Parker assured her he would come without a moment’s delay.
