“You boys must rest on those rugs on that rocky couch there,” said Ranni, speaking to Mike and Jack. “I will hold Paul in my arms to warm him. Pilescu will keep watch for the robbers in case they come back.”

Mike and Jack flung themselves on to the strange resting-place at the back of the platform, and pulled the fur rugs over them. They were asleep in half a second. The two Baronians were sleepy too, but Pilescu was on guard and did not dare even to close his eyes.

Ranni fell asleep holding Paul. Only big Pilescu was awake. He felt his eyes closing. He had switched off his torch, for he did not want the robbers to see any light, if they came back. It was difficult to keep awake in the dark, when he was so tired!

His head nodded. He stood up at once. He knew it would be impossible not to sleep if he remained seated. He began to walk up and down the platform, like a lion in a cage. That kept him awake. He was not likely to fall asleep on his feet.

He paced steadily for two hours. Then he stiffened and listened. He could hear voices! They echoed up from the tunnel below. It must be the returning robbers!

“They have managed to get their raft to the side and land, and have turned back to come after us!” thought Pilescu. “What are we to do? They will be on us before we can escape. How I wish I had a gun with me!”

But the robbers had taken away all the weapons carried by the Baronians. Neither Ranni nor Pilescu had anything to defend themselves with, except their bare hands. Well, they could make good use of those!

The voices came nearer. Pilescu woke Ranni and whispered the news to him. Ranni put the sleeping Paul into the recess at the back, with the other boys. He did not wake.

“We will cover ourselves with our cloaks and sit with our backs to the wall, on either side of the recess,” whispered Ranni. “It is just possible that the robbers may not see us, and may not guess that we are resting here. They would think that we were going ahead as fast as we could.”

They could not hear any voices now. They guessed that the robbers were very near. They carried no torch but were coming along the ledge they knew so well, in complete darkness.
