“Not a dungeon,” he explained. “They have some cells down under the ground but he is in a sort of chamber, a good, big room.”

“Why isn’t he allowed to be in a house?” Nicky demanded.

“Huamachaco, the high priest, is to blame for that,” Bill said. “Cliff’s pa heard in some way that there was a secret pass or some way to get out of the valley and he tried to find it; they caught him and brought him back and then he tamed the eaglet and when they discovered that it was missing and found some torn scraps of paper which he had tried to destroy after he had spoiled the letter he had started on them, Huamachaco, who isn’t any man’s dummy, decided to have the white man watched.”

It was because the chief priest was so clever that Bill feared to take the least chance of upsetting their plans.

Challcuchima, who had become very much attached to Cliff and to his chums, in a respectful awed way, came to visit them while they discussed their plans.

“Holy Chasca,” he said to Cliff in quichua dialect at which Cliff was only fairly proficient, covering up his deficiency by saying very little. “As successor to the Inca rule I have been shown the mysteries of the secret ways beneath the city. Among our hidden treasure is a statue which is like you and yet not like you. My father, the Inca, has permitted me to show it to you that you may say if it is truly your image and if it should be set in the Temple of the Stars.”

Cliff consulted Bill with his eyes and Bill, with a very tiny wink and nod, bade him go. The chums, not invited, looked downcast as Cliff walked across the gardens of gold and silver with his young guide; but Bill soothed them by telling them what he had seen underground.

Cliff was to see far more than was permitted to the eyes of his supposed scholarly servant.

Taking him to the Inca, who greeted him with a mixed respect and good feeling, Challcuchima led Cliff through a tapestried and hidden opening in the private rooms of the palace; then they went down many steps; Cliff had brought a flashlight, an implement which caused Challcuchima much awe and wonder when he was allowed to operate it. Mostly, they used torches as they traversed long passages, twisted around sharp bends, slipped through cross-cuts.

Finally the two came to a huge chamber cut out of the rock. Servants, carrying torches, held their lights high and Cliff had to suppress his tendency to gasp. He had never seen a sight to compare with that which met his eyes.
