That planet, being inhabited by near-human beings, was warm, brightly sun-lit, and had an atmosphere rich in oxygen. Nadreck detested it, since his ideal of a planet was precisely the opposite. Fortunately, however, he would not have to land upon it until after Kandron's arrival—possibly not then—and the fact that his proposed quarry was, like himself, a frigid-blooded poison-breather, made the task of detection a simple one.

Nadreck set his indetectable speedster into a circular orbit around the planet, far enough out to be comfortable, and sent out course after course of delicate, extremely sensitive screen. Precision of pattern-analysis was, of course, needless. The probability was that all legitimate movement of personnel to and from the planet would be composed of warm-blooded oxygen-breathers; that any visitor not so classified would be Kandron. Any frigid-blooded visitor had at least to be investigated, hence his analytical screens had to be capable only of differentiating between two types of beings as far apart as the galactic poles in practically every respect. Nadreck knew that no supervision would be necessary to perform such an open-and-shut separation as that; he would have nothing more to do until his electronic announcers should warn him of Kandron's approach—or until the passage of time should inform him that the Onlonian was not coming to this particular planet.

Being a mathematician, Nadreck knew that any datum secured by extrapolation is of doubtful value. He thus knew that the actual probability of Kandron's coming was less, by some indeterminable amount, than the mathematical one. Nevertheless, having done all that he could do, he waited with the monstrous, unhuman patience known only to such races as his.

Day by day, week by week, the speedster circled the planet and its big, hot sun; and as it circled, the lone voyager studied. He analyzed more data more precisely; he drew deeper and deeper upon his store of knowledge to determine what steps next to take in the event that this attempt should end, as so many previous ones had ended, in failure.

Kinnison, the author, toiled manfully at his epic of space whenever he was under any sort of observation, and enough at other times to avert any suspicion. Indeed, he worked as much as Sybly Whyte, an advertisedly temperamental writer, had ever worked. Besides interviewing the high and the low, and taking notes everywhere, he attended authors' teas, at which he cursed his characters fluently and bitterly for their failure to co-operate with him. With short-haired women and long-haired men he bemoaned the perversity of a public which compelled them to prostitute the real genius of which each was the unique possessor. He sympathized particularly with a fat woman writer of whodunits, whose extremely unrealistic yet amazingly popular Gray Lensman hero had lived through ten full-length novels and twenty million copies.

Even though her real field was the drama, she wasn't writing the kind of detective tripe that most of these crank-turners ground out, she confided to Kinnison. She had known lots of Gray Lensmen very intimately, and her stories were drawn from real life in every particular!

Thus Kinnison remained in character; and thus he was enabled to work completely unnoticed at his real job of finding out what was going on, how the Boskonians were operating to ruin Radelix as they had ruined Antigan IV.

His first care was to investigate the planet's president. That took doing, but he did it. He examined that mind line by line and channel by channel, with no results whatever. No scars, no sign of tampering. Calling in assistance, he searched the president's past even more rigidly than Fossten had searched that of Traska Gannel. Still no soap. Everything checked, even to widely distributed boyhood pictures. Boring from within, then, was out. His first hypothesis was wrong; this invasion and this sabotage were being done from without. How?

Those first leaflets were followed by others, each batch more vitriolic in tone than the preceding one. Apparently they came from empty stratosphere; at least, no ships were to be detected in the neighborhood after any shower of the hand-bills had appeared. But that was not surprising. With its inertialess drive any spaceship could have been parsecs away before the papers touched atmosphere. Or they could have been bombed in from almost any distance. Or, as Kinnison thought most reasonable, they could have been simply dumped out of the mouth of a hyperspatial tube. In any event the method was immaterial. The results only were important; and those results, the Lensman discovered, were entirely disproportionate to the ostensible causes. The subversive literature had some effect, of course, but essentially it must be a blind. No possible tonnage of anonymous printing could cause that much sheer demoralization.
