Yet all the evidence pointed that way: her visit to Plattsburg, her taking the Moth to Canada, her conversation with her brother, at the hotel, in which she referred to her business as dangerous and liable to end in disgrace, and finally her interest in Linda's handkerchief a month or so previous.

Surely no one would doubt such evidence as this! But if the police refused to arrest Miss Hulbert, it would be easy enough to send a picture to the Convent for identification. That would prove everything conclusively.

So both girls felt certain, as they stepped into the Arrow, that they had been successful, that they were about to save Mr. Carlton's business. And this fact meant joy to themselves. Now they could plan again on their flight across the Atlantic; now it would surely be safe to put in the order for the Bellanca which Linda had set her heart upon having.

"Let's don't bother to go back by way of Montreal," said Linda, exultantly, as she started the motor and taxied along the frozen field. "Let's head straight for Spring City!"

"But do you know the way?" inquired Louise, as the plane rose into the air.

"Yes, I guess so. I have a map—oh, not the kind Ted makes, but good enough. We'll fly across country, and stop when we get tired."

"But it's getting dark, Linda," objected her companion.

"We can't help that, Lou! It would be getting dark anyway, even if we were headed for Montreal."

"But this is strange country. So many woods, too. A forced landing would be terrible, Linda."

"Who said anything about a forced landing?" laughed the other girl. She felt thrilled and exhilarated; the cold, fresh air against her cheeks whipped them to a lovely color, and her eyes were shining. She was in the mood for adventure tonight. But when she realized that her chum was dubious, she decided to go easy. Perhaps Louise was tired.
