But Margaret had become sufficiently adept to hold a part of herself aloof from Sasso's influence, and she saved him.

"Behind you!" she hissed. "It's Victor! Kill!" There was surprise and genuine fear in her voice. She had not expected Victor to come after Eldon.

Eldon abandoned all pretense and whirled.

Under other circumstances he might have enjoyed the disconcerted look that over-spread Victor's narrow face. Victor, a few feet away, carried a dagger which he had obviously expected to plunge into Eldon's unprotected back without resistance, as Highness Sin had ordered. Sin's vague suspicions had been enough to order Eldon's death.

"The blast rod! Shoot him!" Margaret whispered urgently, and then she was tumbling aside to avoid the searing backfire of the weapon.

But the moment for which Eldon waited had not yet arrived.

Victor struck out. Eldon sidestepped. And then he fell, tripped by a loop of the cable attached to his wrist. Victor gave a hoarse cry of triumph and moved in. Eldon felt the slashing pain of a flesh wound.

"The blast rod, you fool!" Margaret cried.

But Eldon made no attempt to draw the power weapon. As he regained his feet he snatched a short, heavy sword from the belt of a subordinate officer who was so immersed in the Observance that he was only just becoming aware of the disturbance.

A frightened expression twisted Victor's mouth as he saw his adversary no longer empty-handed, but he knew by the vengeful gleam in Eldon's single eye that this time one of them must surely die. He still held the advantage, for the Force of Sasso confused Eldon's thoughts with alien impressions, interfered with his muscular coordination, drained his strength. And the cable attached to his wrist hindered his movements.
