"From Tardos Mors to John Carter, Kaor!" he said. "The jeddak requests your immediate presence in the Hall of Jeddaks in the imperial palace in Greater Helium."

"At once," I replied.

"May I fly you over, sir?" he asked. "I came in a two-seater."

"Thanks," I replied. "I'll join you at the hangar in a moment." He saluted and left us.

"Who was he?" asked Dejah Thoris. "I don't recall ever having seen him before."

"Probably one of the new officers from Zor, whom Tardos Mors has commissioned in the Jeddak's Guard. It was a gesture of his, made to assure Zor that he has the utmost confidence in the loyalty of that city and as a measure for healing old wounds."

Zor, which lies about three hundred eighty miles southeast of Helium, is one of the most recent conquests of Helium and had given us a great deal of trouble in the past because of treasonable acts instigated by a branch of its royal family led by one Multis Par, a prince. About five years before the events I am about to narrate occurred, this Multis Par had disappeared; and since then Zor had given us no trouble. No one knew what had become of the man, and it was supposed that he had either taken the last, long voyage down the river Iss to the Lost Sea of Korus in the Valley Dor or had been captured and murdered by members of some horde of savage Green men. Nor did anyone appear to care-just so he never returned to Zor, where he was thoroughly hated for his arrogance and cruelty.

"I hope that my revered grandfather does not keep you long," said Dejah Thoris. "We are having a few guests for dinner tonight, and I do not wish you to be late."

"A few!" I said. "How many? Two hundred or three hundred?"

"Don't be impossible," she said, laughing, "Really, only a few."
