He had turned once more to his work, but Johnny had not forgotten. Something within him had been stirred to the depths. He had heard the call of the wilderness, had felt the challenge of the impossible.

In time, having sought out his partner of many adventures, “Panther Eye,” or “Pant” as he was called, he had gone in search of the owner of the red lure. He had found him to be a rich business man.

At first this capitalist, Roderick Grayson, had merely laughed at the proposition which the two boys made—that they be given a try at the red lure. In time he had come to take them more seriously.

At last he had made them a proposition.

“I’m tired of having you about,” he growled good-naturedly. “I’ll give you a chance. You go to Belize, the Capitol of Honduras. That’s a city of twelve thousand. Plenty of men and boats there. I’ll instruct my agent there to furnish you with motor boats and pay for thirty men. You may have them a hundred days, not a day more. At the end of that time you must show me a profit from your expedition or you lose this concession. Is that plain? And satisfactory?”

“Quite.”

“Then good-bye.”

The rich man had bowed them out, and that is how it happened that on this particular night Johnny was far up the Rio Hondo.

“And now this!” Johnny said to himself. “A bolt out of the blue! An apparent attempt at my life. My men vanish. What is to be the end of it all?”

Suddenly he realized that he was alone in the dark; that perils lurked in every corner of the jungle.
