Then while he was still smiling at the thought, comedy changed swiftly and without warning to tragedy.
As the visitor entered the antechamber and the seal closed behind it Conway saw something that was a little like a crocodile with horn-tipped tentacles and a lot like nothing he had ever seen before. He saw the being shrink away from the figures hurrying to meet it, then suddenly dart toward the PVSJ-who was, Conway was to remember later, both the nearest and the smallest. Everybody seemed to be shouting at once then, so much so that Conway’s and presumably everyone else’s Translators went into an ear-piercing squeal of oscillation through sheer overload.
Faced by the teeth and hard-tipped tentacles of the charging visitor the Illensan PVSJ, no doubt thinking of the flimsiness of the envelope which held its life-saving chlorine around it, fled back into the intercorridor lock for the safety of its own section. The visitor, its way suddenly blocked by a Tralthan booming unheard reassurances at it, turned suddenly and scuttled for the same airlock.
All such locks were fitted with rapid action controls in case of emergency, controls which caused one door to open and the other to shut simultaneously instead of waiting for the chamber to be evacuated and refilled with the required atmosphere. The PVSJ, with the berserk visitor close behind it and its suit already torn by the SRTT’s teeth so that it was in imminent danger of dying from oxygen poisoning, rightly considered his case to be an emergency and activated the rapid-action controls. It was perhaps too frightened to notice that the visitor was not completely into the lock, and that when the inner door opened the outer one would neatly cut the visitor in two…
There was so much shouting and confusion around the lock that Conway did not see who the quick-thinking person was who saved the visitor’s life by pressing yet another emergency button, the one which caused both doors to open together. This action kept the SRTT from being cut in two, but there was now a direct opening into the PVSJ section from which billowed thick, yellow clouds of chlorine gas. Before Conway could react, contamination detectors in the corridor walls touched off the alarm siren and simultaneously closed the air-tight doors in the immediate vicinity, and they were all neatly trapped.
For a wild moment Conway fought the urge to run to the air-tight doors and beat on them with his fists. Then he thought of plunging through that poisonous fog to another intersection lock which was on the other side of it. But he could see a maintenance man and one of the DBLF caterpillars in it already, both so overcome with chlorine that Conway doubted if they could live long enough to put on the suits. Could he, he wondered sickly, get over there? The lock chamber also contained helmets good for ten minutes or so-that was demanded by the safety regulations-but to do it he would have to hold his breath for at least three minutes and keep his eyes jammed shut, because if he got a single whiff of that gas or it got at his eyes he would be helplessly disabled. But how could he pass that heaving, struggling mass of Tralthan legs and tentacles spread across the corridor floor while groping about with his eyes shut…
The fear-filled chaos of his thoughts was interrupted by Prilicla, who said, “Chlorine is lethal to my species. Please excuse me.
Prilicla was doing something peculiar to itself. The long, many jointed legs were waving and jerking about as though performing some weird ritual dance and two of the four manipulatory appendages-whose possession was the reason for its species’ fame as surgeons-were doing complicated things with what looked like rolls of transparent plastic sheeting. Conway did not see exactly how it happened but suddenly his GLNO assistant was swathed in a loose, transparent cover through which protruded its six legs and two manipulators-its body, wings and other two members, which were busily engaged in spraying sealing solution on the
leg openings, were completely covered by it. The loose covering bellied out and became taut, proving that it was air-tight.
