"Yes, I'm the inventor," the tanned young man in the dusty overalls answered rather contemptuously: "What did you take me for? ... A French medical student having a joy-ride, or a commis voyageur?"

"Can't say. Never thought! ... Fact is—my wife had frightened me horribly. When your machine bore down on her—posted right in the middle of the gravel—I was scared stiff—give you my honour!—you might have sunk a brace of Dreadnoughts in the palms of my hands!"

Franky made this absurd statement with so sincere an air, and clinched it so effectually by displaying a lovely silk-cambric handkerchief in a state of soppy limpness, that the abrased inventor nearly laughed.

But his thick, silvery, fair eyebrows settled into a straight line across his tanned forehead. He said with a directness that seemed to belong to his lean, keen, hatchet-faced type:

"Drop in on us there," he urged, "as soon as you've found out. Come and dine with us in any case.... No!—we're engaged to-night, but come and lunch at two sharp to-morrow, and tell us all about your hoverer over a bottle of Bubbly. Suite 10, Second Floor. Name of Norwater. Stick this away to remind you," he ended, tendering his card.

"You're awfully good. But at the same time I hardly——"

The voice broke off. A glance at the proffered pasteboard had dyed the inventor flaming scarlet from the collar of his dusty gabardine to the edges of his goggled cap. He dropped the card quietly upon the gravel, and said, looking Franky straight between the eyes:
