"And I suppose your father's being involved would explain why you were suspected," added Linda. "You look like him, I believe."

"Yes. To my regret."

"But perhaps it's better as it is," concluded Linda. "Don't you feel so, Ted?"

"Yes, I do. It—will be so much easier for my mother.... But Linda, we mustn't stand here talking. Every minute is precious to you."

"No. I can't go till Dr. Winston comes out with the surgeon's address. He's putting in a long distance call. However, I will go in and change into my flyer's suit, if you don't mind," she added.

Five minutes later she reappeared with the information that Dr. Lineaweaver was in Louisiana—at a small seaport town which Ted instantly located on a map that he gave to Linda.

"I won't even start off with you," the young man said, "because that would mean an extra stop for you. Now—are you sure you are all right—and that you can stay awake?"

"Yes, I'm sure," replied the girl, forcing a smile. "Mrs. Cates has just given me a thermos bottle full of coffee, and a sandwich, to help me!"

A moment later she climbed into the cockpit and started the motor. The Pursuit, whose engine purred with the smooth even whir of one in perfect order, gained speed until it rose into the air. It was Linda's first flight at night.
