Thus well informed, Nadreck set his speedster into a course toward the planet of Civilization which was Kandron's next objective. He did not hurry; it was no part of his plan to interfere in any way in the horrible program of planet-wide madness and slaughter which Kandron had in mind. It simply did not occur to him to try to save the planet as well as to kill the Onlonian; Nadreck, being Nadreck, took without doubt or question the safest and surest course. Nadreck knew that Kandron would set his vessel into an orbit around the planet, and that he would take a small boat--a flitter--for the one personal visit necessary to establish his lines of communication and control. Vessel and flitter would be alike indetectable, of course; but Nadreck found the one easily enough and knew when the other left its mother-ship. Then, using his lightest, stealthiest spy rays, the Palainian set about the exceedingly delicate business of boarding the Boskonian craft. That undertaking could be made a story in its own right, for Kandron did not leave his ship unguarded. However, merely by thinking about his own safety, Kandron had all unwittingly given away the keys to his supposedly impregnable fortress. While Kandron was wondering whether or not the Lensman was really dead, and especially after he had been convinced that he most probably was, the Onlonian's thoughts had touched fleetingly upon a multitude of closely-related subjects. Would it be safe to abandon some of the more onerous precautions he had always taken, and which had served him so well for so many years? And as he thought of them, each one of his safeguards flashed at least partially into view; and for Nadreck, any significant part was practically as good as the whole. Kandron's protective devices, therefore, did not protect. Projectors, designed to flame out against intruders, remained cold. Ports opened; and as Nadreck touched sundry buttons, various invisible beams, whose breaking would have produced unpleasant results, ceased to exist. In short, Nadreck knew all the answers. If he had not been coldly certain that his information was complete, he would not have acted at all.
