“If we can find the entrance to their lair, we can get soldiers up here, and pen the whole company in, and catch them one by one as they come out,” said Ranni, in a low tone. Pilescu nodded. He heard a sound, and stopped.

“What is it?” whispered Ranni.

“Nothing,” answered Pilescu, after a pause. “I thought I heard something.”

He had! He had heard the fall of a stone dislodged by Jack, who was following them as closely as he dared! The boy stopped when Pilescu stopped, and did not move again until the two men went forward.

In about an hour’s time they were at the old temple. The moon shone in at the ruined entrance. Ranni gave a startled exclamation as he went in, for the moon shone full on the face of the old stone image at the back. It seemed very lifelike!

“Now,” said Ranni, flashing his torch round the cave. “You take a look that side and I’ll take this. Examine every inch of the rock.”

The moon suddenly went behind a big cloud and the world went dark. Jack took the chance of slipping into the cave without the two men seeing him. He thought he could hide behind the images, as the men worked round the cave. He stood behind one near the entrance and watched Ranni and Pilescu examining the rocky wall, trying to find some hidden entrance to another cave beyond.

“I can find nothing,” said Pilescu, in a low voice.

Jack stood behind the statue and watched, hoping that one of the men would discover something. How he wished he could help too — but he was afraid of showing himself in case Ranni was angry again.

He stared at the big squatting statue at the back of the cave. The moon had come out again and was shining full on the image. As Jack watched, a very strange thing began to happen!
