"Queex," the Cargo-apprentice kept his voice to a half whisper, "it got loose and chased something out of the Old Man's cabin down here."
"Queex-!" Ali began and then shut his mouth, moving noiselessly up to join Dane.
The short corridor ended at the hydro entrance. And Dane had been right, there they found the Hoobat, crouched at the closed panel, its claws clicking against the metal as it picked away useless at the portal which would not admit it.
"Whatever it's after must be in there," Dane said softly.
And the hydro, stripped of its luxuriance of plant life, occupied now by the tanks of green scum, would not afford too many hiding places. They had only to let Queex in and keep watch.
As they came up the Hoobat flattened to the floor and shrilled its war cry, spitting at their boots and then flashing claws against the stout metal enforced hide. However, though it was prepared to fight them, it showed no signs of wishing to retreat, and for that Dane was thankful. He quickly pressed the release and tugged open the panel.
At the first crack of its opening Queex turned with one of those bursts of astounding speed and clawed for admittance, its protest against the men forgotten. And it squeezed through a space Dane would have thought too narrow to accommodate its bloated body. Both men slipped around the door behind it and closed the panel tight.
The air was not as fresh as it had been when the plants were there. And the vats which had taken the places of the banked greenery were certainly nothing to look at. Queex humped itself into a clod of blue, immovable, halfway down the aisle.
Dane tried to subdue his breathing, to listen. The Hoobat's actions certainly argued that the alien thing had taken refuge here, though how it had gotten through-? But if it were in the hydro it was well hidden.
He had just begun to wonder how long they must wait when Queex again went into action. Its clawed front legs upraised, it brought the pinchers deliberately together and sawed one across the other, producing a rasping sound which was almost a vibration in the air. Back and forth, back and forth, moved the claws. Watching them produced almost a hypnotic effect, and the reason for such a maneuver was totally beyond the human watchers.
But Queex knew what it was doing all right, Ali's fingers closed on Dane's arm in a pincher grip as painful as if he had been equipped with the horny armament of the Hoobat.
Something, a flitting shadow, had rounded one vat and was that much closer to the industrious fiddler on the floor. By some weird magic of its own the Hoobat was calling its prey to it.
Scrape, scrape-the unmusical performance continued with monotonous regularity. Again the shadow flashed-one vat closer. The Hoobat now presented the appearance of one charmed by its own art-sunk in a lethargy of weird music making.
At last the enchanted came into full view, though lingering at the round side of a container, very apparently longing to flee again, but under some compulsion to approach its enchanter. Dane blinked, not quite sure that his eyes were not playing tricks on him. He had seen the almost transparent globe "bogies" of Limbo, had been fascinated by the weird and ugly pictures in Captain Jellico's collection of tri-dee prints. But this creature was as impossible in its way as the horrific blue thing dragging it out of concealment.
It walked erect on two threads of legs, with four knobby joints easily detected. A bulging abdomen sheathed in the horny substance of a beetle's shell ended in a sharp point. Two pairs of small legs, folded close to the much smaller upper portion of its body, were equipped with thorn shack terminations. The head, which constantly turned back and forth on the armor plated shoulders, was long and narrow and split for half its length by a mouth above which were deep pits which must harbor eyes, though actual organs were not visible to the watching men. It was a palish gray in color-which surprised Dane a little. His memory of the few seconds he had seen it on the Captain's desk had suggested that it was much darker. And erect as it was, it stood about eighteen inches high.
With head turning rapidly, it still hesitated by the side of the vat, so nearly the color of the metal that unless it moved it was difficult to distinguish. As far as Dane could see the Hoobat was paying it no attention. Queex might be lost in a happy dream, the result of its own fiddling. Nor did the rhythm of that scraping vary.
The nightmare thing made the last foot in a rush of speed which reduced it to a blur, coming to a halt before the Hoobat. Its front legs whipped out to strike at its enemy. But Queex was no longer dreaming. This was the moment the Hoobat had been awaiting. One of the sawing claws opened and closed, separating the head of the lurker from its body. And before either of the men could interfere Queex had dismembered the prey with dispatch.
"Look there!" Dane pointed.
The Hoobat held close the body of the stranger and where the ashy corpse came into contact with Queex's blue feathered skin it was slowly changing hue-as if some of the color of its hunter had rubbed off it.
"Chameleon!" Ali went down on one knee the better to view the grisly feast now in progress. "Watch out!" he added sharply as Dane came to join him.
One of the thin upper limbs lay where Queex had discarded it. And from the needle tip was oozing some colorless drops of fluid. Poison?
Dane looked around for something which he could use to pick up the still jerking appendage. But before he could find anything Queex had appropriated it. And in the end they had to allow the Hoobat its victim in its entirety. But once Queex had consumed its prey it lapsed into its usual hunched immobility. Dane went for the cage and working gingerly he and Ali got the creature back in captivity. But all the evidence now left were some smears on the floor of the hydro, smears which Ali blotted up for future research in the lab.
An hour later the four who now comprised the crew of the Queen gathered in the mess for a conference. Queex was in its cage on the table before them, asleep after all its untoward activity.
"There must be more than just one," Weeks said. "But how are we going to hunt them down? With Sinbad?"
Dane shook his head. Once the Hoobat had been caged and the more prominent evidence of the battle scraped from the floor, he had brought the cat into the hydro and forced him to sniff at the site of the engagement. The result was that Sinbad had gone raving mad and Dane's hands were now covered with claw tears which ran viciously deep. It was plain that the ship's cat was having none of the intruders, alive or dead. He had fled to Dane's cabin where he had taken refuge on the bunk and snarled wild eyed when anyone looked in from the corridor.
"Queex has to do it," Rip said. "But will it hunt unless it is hungry?"
He surveyed the now comatose creature skeptically. They had never seen the Captain's pet eat anything except some pellets which Jellico kept in his desk, and they were aware that the intervals between such feedings were quite lengthy. If they had to wait the usual time for Queex to feel hunger pangs once more, they might have to wait a long time.
"We should catch one alive," Ali remarked thoughtfully. "If we could get Queex to fiddle it out to where we could net it-"
Weeks nodded eagerly. "A small net like those the Salariki use. Drop it over the thing-"
While Queex still drowsed in its cage, Weeks went to work with fine cord. Holding the color changing abilities of the enemy in mind they could not tell how many of the creatures might be roaming the ship. It could only be proved where they weren't by where Sinbad would consent to stay. So they made plans which included both the cat and the Hoobat.
Sinbad, much against his will, was buckled into an improvised harness by which he could be controlled without the handler losing too much valuable skin.
And then the hunt started at the top of the ship, proceeding downward section by section. Sinbad raised no protest in the control cabin, nor in the private cabins of the officers' thereabouts. If they could interpret his reactions the center section was free of the invaders. So with Dane in control of the cat and Ali carrying the caged Hoobat, they descended once more to the level which housed the hydro galley, steward's quarters and ship's sick bay.
