"It was an accident," said Rapas. "I was not ready."

"I am sorry," I told him; "go and recover your weapon."

He got it and came back, and this time he lunged at me viciously. There would have been no mere scratch that time if his thrust had succeeded. He would have spitted me straight through the heart. I parried and stepped in, and again his sword hurtled through the air and clanked against the opposite wall.

Fal Sivas laughed uproariously. Rapas was furious. "That is enough," said the former. "I am satisfied. Sheath your swords."

I knew that I had made an enemy of Rapas; but that did not concern me greatly, since being forewarned I could always be watchful of him. Anyway, I had never trusted him.

"You are prepared to enter my service at once?" asked Fal Sivas.

"I am in your service now," I replied.

He smiled. "I think you are going to make me a good man. Rapas wants to go away for a while to attend to business of his own. While he is away, you will remain here as my bodyguard. When he returns, I may still find use for you in one way or another. The fact that you are unknown in Zodanga may make you very valuable to me." He turned to Rapas. "You may go now, Rapas," he said, "and while you are away, you might take some lessons in swordsmanship."

When Pal Sivas said that, he grinned; but Rapas did not. He looked very sour, and he did not say good-bye to me as he left the room.

"I am afraid that you offended his dignity," said Fal Sivas after the door had closed behind the assassin.

"I shall lose no sleep over it," I replied, "and anyway it was not my fault. It was his."

"What do you mean?" demanded Fal Sivas.

"Rapas is not a good swordsman."

"He is considered an excellent one," Fal Sivas assured me.

"I imagine that as a killer he is more adept with the dagger and poison."

"And how about you?" he asked.

"Naturally, as a fighting man, I prefer the sword," I replied.

Fal Sivas shrugged. "That is a matter of small concern to me," he said. "If you prefer to kill my enemies with a sword, use a sword. All I ask is that you kill them."

"You have many enemies?" I asked.

"There are many who would like to see me put out of the way," he replied. "I am an inventor, and there are those who would steal my inventions. Many of these I have had to destroy. Their people suspect me and seek revenge; but there is one who, above all others, seeks to destroy me. He also is an inventor, and he has employed an agent of the assassins' guild to make away with me.

"This guild is headed by Ur Jan, and he personally has threatened my life because I have employed another than a member of his guild to do my killing."
