"He's dead, yes, the ancient Druid is dead . . . . Conrad must have surprised him and killed him . . . . The ancient Druid is dead."

Vorski remained undecided for a while, ready to fall upon the lifeless body and to stab it in his turn. But he dared no more touch it now that it was dead than when it was alive; and all that he had the courage to do was to run and wrench the dagger from the wound.

"Ah," he cried, "you scoundrel, you've got what you deserve! And Conrad is a champion. I shan't forget you, Conrad, be sure of that."

"Where can Conrad be?"

"In the hall of the God-Stone. Ah, Otto, I'm itching to get back to the woman whom the ancient Druid put there and to settle her hash too!"

"Then you believe that she's a live woman?" chuckled Otto.

"And very much alive at that . . . like the ancient Druid! That wizard was only a fake, with a few tricks of his own, perhaps, but no real power. There's the proof!"

"A fake, if you like," the accomplice objected. "But, all the same, he showed you by his signals the way to enter these caves. Now what was his object in that? And what was he doing here? Did he really know the secret of the God-Stone, the way to get possession of it and exactly where it is?"

"You're right. It's all so many riddles," said Vorski, who preferred not to examine the details of the adventure too closely. "But it's so many riddles which'll answer themselves and which I'm not troubling about for the moment, because it's no longer that creepy individual who's putting them to me."

For the third time they went through the narrow communicating passage. Vorski entered the great hall like a conqueror, with his head high and a confident glance. There was no longer any obstacle, no longer any enemy to overcome. Whether the God-Stone was suspended between the stones of the ceiling, or whether the God-Stone was elsewhere, he was sure to discover it. There remained the mysterious woman who looked like Véronique, but who could not be Véronique and whose real identity he was about to unmask.
