Rosemary Sample, whose plane did not go out until the following morning, was there to see them off. So too, quite dried out from the previous night’s adventure, was Willie VanGeldt.

Florence found herself thrilled to the very tips of her toes. As a blue and gold plane with three motors thundering glided away, then with a roar of thunder rose in air, as a small yellow one followed it into the sky, she counted the moments that remained before the number of her own plane should be called and she, walking with all the care-free indifference of the much air-traveled lady (which she was not at all), should march to the three iron steps leading to the plane and climb on board.

“You may think it strange,” Danby was saying to Jeanne, “that we should go to so much trouble to catch one industrial spy, and a lady at that.”

“But no!” Jeanne exclaimed. “Lady spies, they are the most clever and most difficult of all. The great and terrible war proved that.”

“Yes,” Danby agreed. “And in this peace-time war of industry, when great secrets are being guarded, secrets that might win or lose another great war—which, please God, there may never be—the ladies bear watching, I assure you.

“And there are secrets,—” his tone became animated. “Chemical secrets that have made work for thousands, secret processes for heat-treating steel that have revolutionized an entire industry.”

“And secrets that give us better and more beautiful dresses. Ah!” Jeanne laughed a merry laugh. “This is the most wonderful secret of all. For where there is color there is beauty. Beauty brings happiness. Life must be beautiful. So—o, my good friend—” She put forth a slender hand—“I wish you luck! May you and my good friend Florence catch those so very wicked spies and may they be shot at sunrise!

“And now,” her tone changed, “I must say adieu, for see! There is your silver ship wheeling into position. Do not be surprised if some day you see my own little dragon fly coming to light on the top of your flag pole or the landing field nearby.

“And now, Florence!” She gave her good pal a merry poke. “Shoulders up, eyes smiling, the good and jaunty air. Tell the world that this is nothing new. And bon voyage to you both. I shall be seeing you. And I shall be watching, always watching for that dark lady, the most terrible spy.”

Smiling, Florence touched her lips to Jeanne’s fair brow, then putting on her very best air of indifference, which was very good indeed, marched to her plane, climbed the steps, then sank into a soft low seat to let forth a sigh that was half relief and half deep abiding joy.
