"Don't believe everything you hear."

It was Tom Cameron's handwriting—and Ruth knew that the message was meant for her eye and her eye only!

CHAPTER XII

AUNT ABELARD

Of course nothing just like this ever happened save in a fairy story—or in real life. The paper without address, but meant only for Ruth Fielding, had fallen from the aeroplane. She had seen it fall at her feet and could not be mistaken.

Who the two men in the French Nieuport were she could not know. Masked and hooded as they were, she could distinguish the features of neither the pilot nor the man who had dropped the paper bomb. But—she was sure of this—they were somehow in communication with Tom Cameron.

And Tom Cameron was supposed to have gone across the lines to the Germans, or—as Ruth believed—had been captured by them. Yet, if he was a captive, how had he been able to send her this message?

Again, how did he know she was worried about him? He must have reason to suspect that a story was being circulated regarding his unfaithfulness.

Who were those two flying men? Were they German spies? Had Tom been a prisoner in the hands of the Huns, would spies have brought this word from him to her?
