His quick mind flashed over the fascinating prospect; but with equal quickness he saw the reason why Grover sat so silent and unimpressed.

A man accused, anxious to return a jewel, would merit help. A man who knew the real taker of the gem and wanted it restored meant possible trouble. He might want them to help him get the gem away from its possessor.

That was not their duty. It was police work.

“Please be more definite,” Grover said.

“I don’t want you to help me ‘steal’ the gem from anybody,” the medical experimenter declared. “I need financial help to buy it.”

“To buy it,” Roger exclaimed. “That would take a lot of money. Would the people in Tibet pay you?”

“They would pay a handsome profit, Roger. But it would not cost such a vast sum as you may think. You see, the one who has it is not aware of its value.”

“That is curious,” remarked Grover.

“What happened was this: I went to the temple with a native priest to see the marvel I had heard of. While we were entering, a figure slipped away out of another door to the sacred crypt. As we approached the great figure of Buddha, I saw a vacant hole in it and realized that the priceless jewel was gone. Terrified at the thought of being caught, suspected or in some way associated with the crime against their holiest treasure and venerated religious symbol, the priest and I hurried away just as other temple attendants discovered the situation.”

Without being certain, the rest of the gem’s history was assumed to be that the thief, terrified, had thrown away his loot. One of his camp staff, an ignorant, though strong pack-carrying youth from an American city, whose way the doctor had paid for his ability to obey orders without trying to improve on them, had found the gem, in a fissure of the great mountain pass they traversed in escaping.
