This edition has been fully restored with modern typesetting, custom cover design. Arthur Holly knows a bad gamble when he sees one, and Greg's "business opportunity" looks like trouble from the start: a miserable plug of a horse and a buyer named Willy Dunstan with a deal that sounds too clever to trust. But when Holly witnesses the animal's impossible burst of speed on a rocky track, he is pulled into a scheme powered by a hidden antigravity device disguised as binoculars and circuitry tucked beneath the saddle. What begins as a suspicious half-share offer quickly becomes a racing sensation. With jockey Teddy Wills aboard First Hope, Dunstan's invention turns a hopeless horse into a winner, and the stable's fortunes rise with every race. Yet the success carries a nervous edge, and Teddy senses danger even as the profits mount. When a momentary failure in the antigravity control sends First Hope crashing back to earth, the illusion shatters and the hidden machinery is exposed. An investigation follows, Dunstan is pushed into government work, Teddy escapes to race in Mexico City, and Holly is left to contemplate the thin boundary between brilliant invention and outright fraud.
