At last I found the combination and after that it took me only a few seconds to unlock Ptor Fak's shackle. Then a voice behind us spoke.

"What are you doing?" it demanded; "why are you not asleep?"

"How can we sleep with people constantly annoying us?" I asked, hiding the wire beneath me.

"Stand up," said the voice, and as we stood up the shackles fell away from our ankles.

"I thought so," said the voice. Then I saw the piece of wire rise from the ground and disappear. "You are very clever, but I don't think Ptantus will appreciate your cleverness when he hears about this. I shall set a guard to watch you two constantly hereafter."

"Everything is going wrong," I said to Ptor Fak a moment later, after I saw a warrior enter one of the streets, hoping that it was he who had spoken to us and that there were no others around.

"It seems hopeless, doesn't it?" said Ptor Fak.

"No," I snapped, "not while I still live."

The following afternoon Kandus' voice came and sat down beside me. "How goes it?" he asked.

"Terrible," I said.

"How is that?" he asked.

"I can't tell you," I said, "because there is probably a guard standing right here listening to everything that I say."

"There is no one here but us," said Kandus.

"How do you know?" I asked; "your people are as invisible to you as they are to me."

"We learn to sense the presence of others," he explained; "just how, I can't tell you."

"How you do it is immaterial," I said, "as long as you are sure there is no one here listening to us. I will be perfectly frank with you, I succeeded in removing Ptor Fak's shackle and my own. Someone caught me at it and took the piece of wire away from me." I did not tell Kandus that I had broken the wire he had given me in two and that I still had the other half of it in my pocket pouch. There is no use in telling even a friend everything that you know.

"How in the world could you have hoped to escape even if you could remove your shackles?" he asked.

"It was only the first step," I told him. "We really had no plan, but we knew that we certainly could not escape as long as we were shackled."

Kandus laughed. "There is something in that," he said, and then he was silent for a moment. "The girl who was captured with you," he said presently.

"What of her?" I asked.

"Ptanus has given her to Motus," he replies; "it was all done very suddenly. Why, no one seems to know, because Ptantus hasn't any particular love for Motus."
