“Snapped it when you weren’t looking. Those newspaper reporters are up to all sorts of tricks. The beacon light is bright, and he had a special camera.”

Linda looked serious.

“This may make trouble for us, Dot,” she said, in a low voice.

The director and his secretary got out of the car and advanced towards the girls just as an airplane loomed into view. Linda stared excitedly at the sky, trying to make out what kind of plane it was. It was not an autogiro.

“There she is!” shouted Mr. Von Goss, and Mr. Sprague took off his hat and waved it violently into the air.

“The secretary’s pretty keen about the false Linda, or I miss my guess,” whispered Dot, in her companion’s ear. “Look how excited he is! How wildly he’s waving!”

The aviatrix, who was just overhead, suddenly banked her plane, and made a turn to the left. Then she nosed her plane higher into the air.

“Doing some stunts for us!” exclaimed Mr. Von Goss. “She’s a great little flier, all right—”

“She’s—she’s going away!” faltered Linda, in deepest disappointment.

“Probably forgotten something,” remarked Leslie Sprague, casually. “I was almost certain, anyhow, that she said three o’clock—not two. She’ll most likely be back at three.”
