 			<p>Dane Thorson, Cargo-master-apprentice of the <i epub:type="se:name.vessel.ship">Solar Queen</i>, Galactic Free Trader spacer, Terra registry, stood in the middle of the ship’s cramped bather while Rip Shannon, assistant Astrogator and his senior in the Service of Trade by some four years, applied gobs of highly scented paste to the skin between Dane’s rather prominent shoulder blades. The small cabin was thickly redolent with spicy odors and Rip sniffed appreciatively.</p>
 			<p>“You’re sure going to be about the best smelling Terran who ever set boot on Sargol’s soil,” his soft slur of speech ended in a rich chuckle.</p>

 			<p>Since Mura was in the isolation of ship sick bay the stripping of his cabin was a relatively simple job. But, though Rip and Dane went over it literally by inches, they found nothing unusual⁠—in fact nothing from Sargol except a small twig of the red wood which lay on the steward’s worktable where he had been fashioning something to incorporate in one of his miniature fairy landscapes, to be imprisoned for all time in a plasta-bubble. Dane turned this around in his fingers. Because it was the only link with the perfumed planet he couldn’t help but feel that it had some importance.</p>
 			<p>But Kosti had not shown any interest in the wood. And he, himself, and Weeks had handled it freely <em>before</em> they had tasted Groft’s friendship cup and had no ill effects⁠—so it couldn’t be the wood. Dane put the twig back on the work table and snapped the protecting cover over the delicate tools⁠—never realizing until days later how very close he had been in that moment to the solution of their problem.</p>

To go beyond the shielding walls of the spacer into that riotous green world would sentence them to death as surely as if the Patrol was without, with a flamer trained on their hatch.

 			<p>Oddly enough, in spite of the tension which must have boiled within him, Rip brought them in with a perfect four-fin-point landing⁠—one which, under the circumstances, must win him the respect of master star-star pilots from the Rim. Though Dane doubted whether if they lost, that skill would bring Shannon anything but a long term in the moon mines. The actual jar of their landing contact was mostly absorbed by the webbing of their shock seats and they were on their feet, ready to move almost at once.</p>
 			<p>The next operation had been planned. Dane gave a glance at the screen. Ringed now about the <i epub:type="se:name.vessel.ship">Queen</i> were the buildings of Terraport. Yes, any attempt to attack the ship would endanger too much of the permanent structure of the field itself. Rip had brought them down⁠—not on the rocket-scarred outer landing space⁠—but on the concrete apron between the Assignment Center and the control tower⁠—a smooth strip usually sacred to the parking of officials’ ground scooters. He speculated as to whether any of the latter had been converted to molten metal by the exhausts of the <i epub:type="se:name.vessel.ship">Queen</i>’s descent.</p>

 			<p>“⁠—and so we landed here, sir,” Rip concluded his report in the matter-of-fact tone he might have used in describing a perfectly ordinary voyage, say between Terraport and Luna City, a run of no incident and dull cargo carrying.</p>
 			<p>The crew of the <i epub:type="se:name.vessel.ship">Solar Queen</i>, save for Tau, were assembled in a room somewhere in the vastness of Patrol Headquarters.

 			<p>Although Traders by law and tradition carried no more potent personal weapons⁠—except in times of great crisis⁠—than hand sleep rods, the resultant shot from the latter was just as unpleasant for temporary periods as a more forceful beam⁠—and the threat of it was enough to halt the three men who had come to the foot of the <i epub:type="se:name.vessel.ship">Queen</i>’s ramp and who could see the rod held rather negligently by Ali.

 			<p>But the interruption had disturbed the tenor of trading. The small chief who had so eagerly taken Paft’s place had only two Koros stones to offer and even to Dane’s inexperienced eyes they were inferior in size and color to those the other clan leader had tendered. The Terrans were aware that Koros mining was a dangerous business but they had not known that the stock of available stones was so very small. Within ten minutes the last of the serious bargaining was concluded and the clansmen were drifting away from the burned-over space about the <i epub:type="se:name.vessel.ship">Queen</i>’s standing fins.</p>

All the Salariki were young and the parties babbled together in excitement. It was plain that this hunt, staged upon a large scale, was not only a means of revenge upon a hated enemy but, also, a sporting event of outstanding prestige.</p>
 			<p>Now the grass trees began to show ragged gaps, open spaces between their clumps, until the forest was only scattered groups and the party the Terrans had joined walked along a trail cloaked in knee-high, yellow-red fern growth. Most of the Salariki carried unlit torches, some having four or five bundled together, as if gorp hunting must be done after nightfall. And it <em>was</em> fairly late in the afternoon before they topped a rise of ground and looked out upon one of Sargol’s seas.</p>

 			<p>Inside the red stockade there was a crowded community. The Salariki demanded privacy of a kind, and even the unmarried warriors did not share barracks, but each had a small cubicle of his own. So that the mud brick and timber erections of one of their clan cities resembled nothing so much as the comb cells of a busy beehive. Although Paft’s was considered a large clan, it numbered only about two hundred fighting men and their numerous wives, children and captive servants. Not all of them normally lived at this center, but for the funeral feasting they had assembled⁠—which meant a lot of doubling up and tenting out under makeshift cover between the regular buildings of the town. So that the Terrans were glad to be guided through this crowded maze to the Great Hall which was its heart.</p>
 			<p>As the trading center had been, the hall was a circular enclosure open to the sky above but divided in wheel-spoke fashion with posts of the red wood, each supporting a metal basket filled with inflammable material. Here were no lowly stools or trading tables. One vast circular board, broken only by a gap at the foot, ran completely around the wall. At the end opposite the entrance was the high chair of the chieftain, set on a two-step dais. Though the feast had not yet officially begun, the Terrans saw that the majority of the places were already occupied.</p>

From that point on there was nothing to do but wait out the usual dull time of flight between systems and hope that Steen Wilcox had plotted a course which would cut that flight time to a minimum. But this voyage there was little relaxation once they were in Hyper.

When he had first joined the <i epub:type="se:name.vessel.ship">Queen</i> as a recruit straight out of the training Pool, he had speedily learned that all the ten years of intensive study then behind him had only been an introduction to the amount he still had to absorb before he could take his place as an equal with such a trader as Van Rycke⁠—if he had the stuff which would raise him in time to that exalted level. While he had still had his superior’s favor he had dared to treat him as an instructor, going to him with perplexing problems of stowage or barter. But now he had no desire to intrude upon the Cargo-master, and doggedly wrestled with the microtapes of old records on his own, painfully working out the why and wherefor for any departure from the regular procedure. He had no inkling of his own future status⁠—whether the return to Terra would find him permanently earthed. And he would ask no questions.</p>
