Vultures of Lost Valley

Published in Flying Aces, November 1936.
"Down upon the flood-lit Washington Airport came a sleek Douglas transport. And from it ran a strangely-costumed girl wielding a glittering dagger in spirited attempts to protect herself from the burly men who sought to stop her. Only the lightning decision of a tall, well-built man in a car on the driveway saved her. That man was Richard Knight. And this surprising incident was destined to send him upon the most startling adventure of his career - an adventure which, wholly unknown to him, had begun more than half a century before he was born."
