And through it all, the Wall Street battle went on against the undiscoverable and powerful enemy who had launched what Francis and Bascom could not avoid acknowledging was a catastrophic, war-to-the-death raid on his fortune.

“If only we can avoid throwing Tampico Petroleum into the whirlpool,” Bascom prayed.

“I look to Tampico Petroleum to save me,” Francis replied. “When every security I can lay hand to has been engulfed, then, throwing in Tampico Petroleum will be like the eruption of a new army upon a losing field.”

“And suppose your unknown foe is powerful enough to swallow down that final, splendid asset and clamor for more?” Bascom queried.

Francis shrugged his shoulders.

“Then I shall be broke. But my father went broke half a dozen times before he won out. Also was he born broke. I should worry about a little thing like that.”

For a time, in the Solano hacienda, events had been moving slowly. In fact, following upon the rescue of Leoncia by Henry along his dynamite-sown trail, there had been no events. Not even had Yi Poon appeared with a perfectly fresh and entirely brand new secret to sell. Nothing had happened, save that Leoncia drooped and was apathetic, that neither Enrico nor Henry, her full brother, nor her Solano brothers who were not her brothers at all, could cheer her.

But, while Leoncia drooped, Henry and the tall sons of Enrico worried and perplexed themselves about the treasure in the Valley of the Lost Souls, into which Torres was even then dynamiting his way. One thing they did know, namely, that the Torres’ expedition had sent Augustino and Vicente back to San Antonio to get two more mule-loads of dynamite.

It was Henry, after conferring with Enrico and obtaining his permission, who broached the matter to Leoncia.

“Sweet sister,” had been his way, “we’re going to go up and see what the scoundrel Torres and his gang are doing. We do know, thanks to you, their objective. The dynamite is to blow an entrance into the Valley. We know where the Lady Who Dreams sank her treasure when her house burned. Torres does not know this. The idea is that we can follow them into the Valley, when they have drained the Maya caves, and have as good a chance, if not a better chance than they in getting possession of that marvelous chest of gems. And the very tip of the point is that we’d like to take you along on the expedition. I fancy, if we managed to get the treasure ourselves, that you wouldn’t mind repeating that journey down the subterranean river.”
