"I am Silvaris, King of the Fox People," he said swiftly. "On the Flaming Diamond depends our ability to exist. Night is almost upon us again, but unless the diamond can be restored to the paw of the bear, there will be no more night or day."

"But you have it!" Drake protested. "Lardner came here to get it back again...."

"Lardner came by mistake to this valley six months ago," Silvaris said brokenly. "We welcomed him as we welcome all people. He betrayed our trust and stole our life source. We took him to our hearts as Sylvia and I were taken many years ago."

"Then you aren't really of the same race?" Drake's voice was filled with relief.

Silvaris shook his head.

"We are here by our own choice," he went on. "Sylvia and I, lost children, found our way here from a trapper's cabin when we were very young. We never tried to leave. When Lardner stole our precious gem, she and I alone knew the ways of civilization. It was our task to return the stone to its rightful place."

"If that diamond is the solution of this mess," Puffy asked in a puzzled voice, "why don't we clean up the mystery right now?"

"Wait!"

Silvaris went slowly down the long steps to the fox pit. He climbed the steps to the side of the polar bear and his sister's lifeless body. From her armpit, he took a huge gem. As he came toward them, Drake knew it was the Lardner stone, flashing and alive in the semi-darkness.

He pushed it into Drake's hands.
