CHAPTER II
Conference
aptain Richard Rennell, of the U. S. Air Service, but temporarily detached to Intelligence, thought that Fredegonde Valmy had never looked so lovely as when he helped her out of the cockpit.
Her dark hair fell in disorder over her flushed cheeks, and her eyes were sparkling with pleasure.
"A thousand thanks, M'sieur Rennell," she said, in her low voice with its slight foreign intonation. "Never have I enjoyed a ride more than to-day. And I shall see you at Mrs. Wansleigh's ball to-night?"
"I hope so—if I'm not wanted at Headquarters," answered Dick, looking at the girl in undisguised admiration.
"Ah, that Headquarters of yours! It claims so much of your time!" she pouted. "But these are times when the Intelligence Service demands much of its men, is it not so?"
"Who told you I was attached to Intelligence?" demanded Dick bluntly.
