He inspected Onlo thoroughly, he cautioned his officers repeatedly and insistently to keep alert against every conceivable emergency while he was so unavoidably absent. Then he departed, with a fleet of vessels manned by hand-picked crews, to a long-prepared and hitherto secret retreat. From that safe place he watched, through the eyes and the instruments of his skilled observers, everything that occurred. Thrale fell, and Onlo. The Patrol triumphed. Then, knowing the full measure of the disaster and accepting it with the grim passivity so characteristic of his breed, Kandron broadcast certain signals and one of his--and Alcon's--superiors got in touch with him. He reported concisely. They conferred. He was given orders which were to keep him busy for over twenty Tellurian years. He knew now that Onlo had been invaded, tracelessly, by some feat of mentality beyond comprehension and almost beyond belief. He knew that Onlo had fallen without any of its defenders having energized a single one of their gigantic engines of war. The fall of Thrale, and the manner of that fall's accomplishment, were plain enough. Human stuff. The work, undoubtedly, of human Lensmen; perhaps the work of the human Lensman who was so frequently associated with Star A Star. But Onlo! Kandron himself had set those snares along those intricately zigzagged communications lines; he knew their capabilities. Kandron himself had installed Onlo's blocking and shielding screens; he knew their might. He knew, since no other path existed leading to Thrale, that those lines had been followed and those screens had been penetrated, and all without setting off a single alarm. Those things had actually happened. Hence Kandron set his stupendous mind to the task of envisaging what the being must be, mentally, who could do them; what the mind of this Star A Star--it could have been no one else--must in actuality be. He succeeded. He deduced Nadreck of Palain VII, practically _in toto_; and for the Star A Star thus envisaged he set traps throughout both galaxies. They might or might not kill him. Killing him immediately, however, was not really of the essence; that matter could wait until he could give it his personal attention. The important thing was to see to it that Star A Star could never, by any possible chance, discover a true lead to any high Boskonian. Sneeringly, gloatingly, Kandron issued orders; then flung himself with all his zeal and ability into the task of reorganizing the shattered fragments of the Boskonian Empire into a force capable of wrecking Civilization.
