“Now to see the fun!” chuckled Penny.

The keeper had appeared on the platform and was gazing down upon the visitor. He called something to the woman that Penny could not hear. But to her amazement, Mrs. Deline started up the iron stairway.

Penny waited expectantly. She was certain that the keeper of the light would order Mrs. Deline away. Instead, he greeted her with a hearty handshake as if they were old friends. They entered the lighthouse tower room together, and the heavy door closed behind them.

“Well, if that isn’t strange!” Penny muttered. “I wasn’t permitted to set foot inside the lighthouse, but in goes Mrs. Deline without a single question asked!”

Her curiosity aroused, the girl decided to wait and watch. Twenty minutes elapsed. During that time Mrs. Deline did not reappear. Penny grew tired of her vigil.

“Have a nice trip, Lou?”
