"The fellow is in the employ of Hadron of Hastor," shouted Sil Vagis. "He speaks nothing but lies. I attacked them when they came, but there were many and they overpowered me. This fellow was not present."

"Let me see thy head," I said to the slave, and when he had come and knelt before me I saw a great red welt the length of one side of his head above the ear, just such a welt as a glancing blow from the flat side of a long sword might have made. "Here," I said to Tor Hatan, pointing to the great welt, "is the proof of a slave's loyalty and courage. Let us see the wounds received by a noble of Helium who by his own testimony engaged in single-handed combat against great odds. Surely in such an encounter he must have received at least a single scratch."

"Unless he is as marvelous a swordsman as the great John Carter himself," said the dwar of the palace guard with a thinly veiled sneer.

"It is all a plot," cried Sil Vagis. "Do you take the word of a slave, Tor Hatan, against that of a noble of Helium?"

"I rely on the testimony of my eyes and my senses," replied the odwar, and he turned his back upon Sil Vagis and again addressed the slave. "Didst thou recognize any of those who abducted Sanoma Tora," he demanded, "or note their harness or their metal?"

"I got no good look at the face of any of them, but I did see the harness and the metal of him whom I tried to drag from the flier."

"Was it the metal of Hastor?" asked Tor Hatan.

"By my first ancestor, it was not," replied the slave emphatically; "nor was it the metal of any other city of the Empire of Helium. The design and the insignia were unknown to me, and yet there was a certain familiarity about them that tantalizes me. I feel that I have seen them before, but when and where I cannot recall. In the service of my jed I fought invaders from many lands and it may be that upon some of these I saw similar metal many years ago."

"Are you satisfied, Tor Hatan," I demanded, "that the aspersions cast upon me by Sil Vagis are without foundation?"

"Yes, Hadron of Hastor," replied the odwar.
