"They can't do any more to us than they can for running in a plague ship," Ali pointed out. "Either will get us blasted if we happen into the wrong vector now. So--what do we do?" "We find out what the plague really is," Dane said and meant every word of it. "How?" Ali inquired. "Through some of Craig's magic?" Dane was forced to answer with the truth. "I don't know yet--but it's our only chance." Rip rubbed his eyes wearily. "Don't think I'm disagreeing--but just where do we start? We've already combed Frank's quarters and Kosti's--we cleaned out the hydro--" "Those tri-dee shots of the hydro--have you checked them yet?" Dane countered. Without a word Ali arose and left the cabin. He came back with a microfilm roll. Fitting it into the large projector he focused it on the wall and snapped the button. They were looking at the hydro--down the length of space so accurately recorded that it seemed they might walk straight into it. The greenery of the plants was so vivid and alive Dane felt that he could reach out and pluck a leaf. Inch by inch he examined those ranks, looking for something which was not in order, had no right to be there. The long shot of the hydro as it had been merged into a series of sectional groupings. In silence they studied it intently, using all their field lore in an attempt to spot what each one was certain must be there somewhere. But they were all handicapped by their lack of intimate knowledge of the garden. "Wait!" Weeks' voice scaled up. "Left hand corner--there!" His pointing hand broke and shadowed the portion he was calling to their attention. Ali jumped to the projector and made a quick adjustment. Plants four and five times life size glowed green on the wall. What Weeks had caught they all saw now--ragged leaves, stripped stems. "Chewed!" Dane supplied the answer. It was only one species of plant which had been so mangled. Other varieties in the same bank showed no signs of disturbance. But all of that one type had at least one stripped branch and two were virtual skeletons. "A pest!" said Rip. "But Sinbad," Dane began a protest before the memory of the cat's peculiar actions of the past weeks stopped him. Sinbad had slipped up, the hunter who had kept the Queen free of the outré alien life which came aboard from time to time with cargo, had not attacked that which had ravaged the hydro plants. Or if he had done so, he had not, after his usual custom, presented the bodies of the slain to any crew member. "It looks as if we have something at last," Ali observed and someone echoed that with a sigh of heartdeep relief. Chapter XII STRANGE BEHAVIOR OF A HOOBAT "All right, so we think we know a little more," Ali added a moment later. "Just what are we going to do? We can't stay in space forever--there're the small items of fuel and supplies and--" Rip had come to a decision. "We're not going to remain space borne," he stated with the confidence of one who now saw an open road before him.
