“I should have told you we would be protected,” Peter said from behind them.

“If this is protection,” Judy retorted, “I’d rather be thrown to the lions. Where did that voice come from? It even startled Blackberry. There he goes, up to the top of the statue to explore!”

“I doubt if he will find anything. The voice you heard was probably that of the chief deputy, and I believe it came from inside the vault. He and his rangers are determined to find out who set that fire, if it was set, and how it happened that the mansion was so conveniently emptied just before the blaze. I knew they’d be there,” Peter explained. “They’re on the lookout for the thieves—”

“But you said there weren’t any thieves,” Judy reminded him.

Again the magician and Peter exchanged glances.

“That remains to be seen. Anyway, the magician believes something strange is going on here, and he is in a position to know.”

“How can he know?” gasped Judy, and added, laughing, “Has he mystical knowledge from the mysterious East?”

But Peter was serious when he said, “Our plans went wrong somewhere. They may have been too obvious. At any rate, we know the police are somewhere in the vicinity. It should be perfectly safe to explore.”

“Do you think this mystical knowledge of yours will help us find the cave?” asked Judy. “I’m like Blackberry. I prefer to look in high places. I think I’ll climb up on top of the vault and see what’s there.”

“Blackberry sure looks as if he’s trying to show you something,” agreed Peter. “Be careful, though. It may be slippery.”
