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. But Kosti had not shown any interest in the wood. And he, himself, and Weeks had handled it freely _before_ they had tasted Graft'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. After two hours of shifting every one of the steward's belongings, of crawling on hands and knees about the deck and climbing to inspect perfectly bare walls, they had found exactly nothing. Rip sat down on the end of the denuded bunk. "There's the hydro--Frank spent a lot of time in there--and the storeroom," he told the places off on his fingers. "The galley and the mess cabin." Those had been the extent of Mura's world. They could search the storeroom, the galley and the mess cabin--but to interfere with the hydro would endanger their air supply. It was for that very reason that they now looked at each other in startled surmise. "The perfect place to plant something!" Dane spoke first. Rip's teeth caught his underlip. The hydro--something planted there could not be routed out unless they made a landing on a port field and had the whole section stripped. "Devilish--" Rip's mobile lips drew tight. "But how could they do it?" Dane didn't see how it could have been done either. No one but the Queen's own crew had been on board the ship during their entire stay on Sargol, except for the young Salarik. Could that cub have brought something? But he and Mura had been with the youngster every minute that he had been in the hydro. To the best of Dane's memory the cub had touched nothing and had been there only for a few moments. That had been before the feast also-- Rip got to his feet. "We can't strip the hydro in space," he pointed out the obvious quietly. Dane had the answer. "Then we've got to earth!" "You heard that warn-off. If we try it--" "What about an Emergency station?" Rip stood very still, his big hands locked about the buckle of his arms belt. Then, without another word, he went out of the cabin and at a pounding pace up the ladder, bound for the Captain's cabin and the records Jellico kept there. It was such a slim chance--but it was better than none at all.
