At sight of Ur Jan and me standing side by side, The Rat went ashen grey. He started to turn, as though to run; but evidently he thought better of it, for he immediately faced us again, and stood staring at us as though fascinated.

As we approached him, he affected a silly grin. "Well, Vandor," he said, "this is a surprise. I am glad to see you."

"Yes, you must be," I replied. "What are you doing here?"

"I came to see Fal Sivas."

"Did you expect to find him here?" demanded Ur Jan.

"Yes," replied Rapas.

"Then why were you sneaking in on your tiptoes?" inquired the assassin. "You are lying, Rapas. You knew that Fal Sivas was not here. If you had thought that he was here, you would not have had the nerve to come, for you knew that he knew that you were in my employ."

Ur Jan stepped forward quickly and grasped Rapas by the throat. "Listen, you rat," he growled; "you know where Fal Sivas is. Tell me, or I'll wring your neck."

The fellow commenced to grovel and whine, "Don't, don't; you are hurting me," he cried. "You will kill me."

"At least you have told the truth for once," growled the assassin. "Quick now; out with it. Where is Fal Sivas?"

"If I tell you, will you promise not to kill me?" asked The Rat.

"We will promise you that and more," I said; "Tel us where Fal Sivas is, and I'll give you your weight in treasure."

"Speak up," said Ur Jan, giving the fellow a shake.

"Fal Sivas is in the house of Gar Nal," whispered Rapas, "but don't tell him that I told you; don't tell him that I told you or he will kill me horribly."

I did not dare turn Rapas loose for fear he would betray us, and furthermore he promised to gain entrance to Gar Nal's for us and lead us to the room where we would find Fal Sivas.

I could not imagine what Fal Sivas was doing in the house of Gar Nal, unless he had gone there in Gar Nal's absence in an attempt to steal some of his secrets; nor did I bother to question Rapas about it, as it did not seem of any great importance to me. It was enough that Fal Sivas was there, and that I should find him.

It was half after the eighth zode, or around midnight earth-time, that we reached Gar Nal's. Rapas admitted us and led us to the third level of the house, up narrow ramps at the rear of the building where we met no one. We moved silently without speaking, and at last our guide halted before a door.

"He is in there," he whispered.

"Open the door," I said.

He tried it, but it was locked. Ur Jan pushed him aside, and then hurled his great bulk against the door. With a loud splintering of wood, it burst in. I leaped across the threshold; and there, seated at a table, I saw Fal Sivas and Gar Nal—Gar Nal, the man whom I had thought to be imprisoned in the city of Ombra on the nearer moon.
