Worsel took great care that the opposing commander was not killed with his minions. The fighting over, the Velantians chained this sole survivor into one of his own racks and stretched him out into immobility. Then, restraining by main strength the terrific urge to put the machine then and there to its fullest ghastly use, Worsel cut his screen, threw a couple of turns of tail around a convenient anchorage, and faced the Boskonian almost nose to nose. Eight weirdly stalked eyes curled out as he drove a probing thought-beam against the monster's shield.

"I could use this—or this—or this," Worsel gloated. As he touched various wheels and levers the chains hummed slightly, sparks flashed, the rigid body twitched. "I am not going to, however—yet. While you are still sane I want to take and I shall take your total knowledge."

And face to face, eye to eye, brain to brain, that silently and motionlessly cataclysmic battle was joined.

As has been said, Worsel had hunted down and had destroyed many Overlords. He had hunted them, however, like vermin. He had destroyed them with duodec bombs and with primary or secondary beams; or, at closest hand, with talons, teeth, and tail. He had not engaged an Overlord mind to mind for over twenty Tellurian years; not since he and Nadreck of Palain VII had captured alive the leaders of those who had been preying upon Helen's matriarchs and warring upon Civilization from their cavern upon Lyrane II. Nor had he ever dueled one mentally to death without powerful support; Kinnison or some other Lensman had always been near by.

But Worsel would need no help. He was not shivering in eagerness now. His body was as still as the solid rock upon which most of it lay; every chamber and every faculty of his mind was concentrated upon battering down or cutting through the Overlords' stubbornly-held shields.

Brighter and brighter glowed the Velantian's Lens, flooding the gloomy cave with pulsating polychromatic light. Alert for any possible trickery, guarding intently against any possibility of riposte or of counterthrust, Worsel leveled bolt after bolt of mental force. He surrounded the monster's mind with a searing, constricting field. He squeezed; relentlessly and with appalling power.

The Overlord was beaten. He, who had never before encountered a foreign mind or a vital force stronger than his own, knew that he was beaten. He knew that at long last he had met that half-fabulous Velantian Lensman with whom not one of his monstrous race could cope. He knew starkly, with the chilling, numbing terror possible only to such a being in such a position, that he was doomed to die the same hideous and long-drawn-out death which he had dealt out to so many others. He did not read into the mind of the bitterly vengeful, the implacably ferocious Velantian any more mercy or any more compunction than was actually there. He knew perfectly that of either there was no slightest trace. Knowing these things with the blackly appalling certainty that was his, he quailed.

There is an old but cogent saying that the brave man dies only once, the coward a thousand times. That Overlord, during that lethal combat, died more times than it is pleasant to contemplate. Nevertheless, he fought. A cornered rat will fight, and the Delgonian was not a rat—not exactly, that is, an ordinary rat. His mind was competent, keen, powerful, and utterly unscrupulous; and he brought to the defense of his beleaguered ego every resource of skill and of trickery and of sheer power at his command—in vain. Deeper and deeper, in spite of everything he could do, the relentless Lensman squeezed and smashed and cut and pried and bored; little by little the Overlord gave mental ground.

"This station is here ... this staff is here ... I am here, then ... to wreak damage ... all possible damage ... to the commerce ... and to the personnel of ... the Galactic Patrol ... and Civilization in every aspect—" the Overlord admitted haltingly as Worsel's pressure became intolerable; but such admissions, however unwillingly made or however revealing in substance, were not enough.

Worsel wanted, and would be satisfied with nothing less than, his enemy's total knowledge. Hence he maintained his assault until, unable longer to withstand the frightful battering, the Overlord's barriers went completely down; until every convolution of his brain and every track of his mind lay open, helplessly exposed to Worsel's poignant scrutiny. Then, scarcely taking time to gloat over his victim, Worsel did scrutinize.
