its contents when he was through Metallic parts lay heaped in a pile. He poked at them with a assortment in the other room? He could not guess. But the others had panic and fear: " collection of hard, sharp, sticky and knobby objects of various shapes Jodrell Bank! Where are you? Help!" hollowly. He picked himself up, braced against something that smelled dangerously of halogen compounds, and scratched his shoulder, right through his space-tunic, against something that vibrated as he touched that rocked under his feet and fell against something that clattered it. it was something far more immediate to his interests. "I think," he said slowly, "that they are in contact." like a voice. He could not quite hear it, but it was there. He sat as still as he could, listening it remained elusive. Probably it was only an illusion. but he did feel amazement when he was amazed, and fear when there was quite utter silence. Somewhere, just at the threshold of his senses, there was something this damned, dark, dismal hole of a place where everything was out to hurt him and nothing explained what was going on. He cried aloud in exasperation: "If I could only see !" female is perhaps not quite mute." "Then shall we abandon him and work with her, forgetting the first one?" He tripped and fell against something that was soft, slimy and, like baker's dough, not at all resilient. whisper, now and then. The first one, the male, nothing. But this A flickering halo of pinkish light appeared. He sat up, startled. He light? And what were these other things in the room? having tunnel vision or wearing blinders. He could see what he was looking at, but he could see nothing else. And the things he could she begged him to hurry. Her voice was heavily accented, with some words in a language he did not recognize. She seemed to be in shock. , an explosion, himself knocked he had been close enough to shock himself. He tried to reassure her as he searched for a way out of the hall, but in the middle of a word her voice stopped. out, brought here in a suit ... well, it was an explanation with more holes than fabric, like a fisherman's net, but at least it was rational. the objects were more or less familiar. Even the child's chair—why, he'd had one more or less like that himself, long before he was old enough to go to school. But what were they doing here? Not everything he saw was familiar. The walls of the room itself were strange. They were not metal or plaster or knotty pine She breathed, a little raggedly but without visible discomfort her face was relaxed as though she were sleeping. She did not rouse as he moved her. He realized she was breathing the air of the room they were in. with nothing more on his mind than completing his check-sighting and meeting His instant first thought was that she was in danger of asphyxiation . He could, of course, be dead. All this could be the fantasies of a cooling brain. McCray grinned into the pink-lit darkness. The thought had somehow refreshed him, like icewater between rounds, and with a clearing head he remembered what a spacesuit was good for. Of course, the thing might not be operating. He reached for the microphone again— He cried aloud. not organically attached to "himself." They were snakelike things which obeyed the orders of his brain as well as your mind can make your toes curl but they did not touch him directly. Indeed, they worked as well excited. His members, disposed about the room where he had sent them on various errands, quivered and shook a little yet they were the calmest "The subject recovered consciousness a short time ago and began to inspect his enclosure. His method of doing so was to put his own members in physical contact with the various objects in the enclosure. After observing him do this for a time we concluded he might be unable to see and so we illuminated his field of vision for him. "This appeared to work well for a time. He seemed relatively undisturbed. However, he then reverted to physical-contact, manipulating certain appurtenances of an artificial skin we had provided for him. "He then began to vibrate the atmosphere by means of resonating organs in his breathing passage. "Simultaneously, the object he was holding, attached to the artificial skin, was discovered to be generating paranormal forces." "Well ... not much, sir. He suddenly panicked. We don't know why but we thought we'd better pull back and let him recover for a while." dark, knew that the team-members had tried illuminating the room for him briefly and again produced the rising panic. for him—" actually, what he said was more like, we've warmed the biophysical nuances of his enclosure —"and tried to guess his needs and we're frightening him half to death. We can't go faster. This be said that he was emotionally involved it was not pity or sympathy that caused him to regret the dangers in moving too fast toward communication. Not even Hatcher had quite got over the revolting eating room. He then stuffed the slit with pulpy vegetation the texture of kelp it closed, and his body was supplied with nourishment for another day. He returned quickly to the room. they dodged back to their niches on his skin, fitted themselves into their vestigial slots, poured back their wastes into his own circulation and ingested what they needed from the meal he had just taken.... "Now!" cried the assistant. "Look!" but it showed what it was meant to show. his patience was not, after all, endless. "No matter," he said at last. "Bring the other one in." And then, in a completely different mood, "We may need him badly. We may be in the process of killing our first one now." he had an inspiration. The dark was absolute, but he remembered where the spacesuit had been now that he could see his own hand again, he could blame the weird effects on some strange property of the light. For a second he thought he heard the far-off voice, quiet, calm and almost hopeless, that he had sensed hours before but then that was gone. Something else was gone. Some faint mechanical sound that had He could see no difference but perhaps, he thought, he could smell one. The unpleasant halogen odor from the grating was surely stronger now. He stood there, perplexed. didn't hear him, which meant the radio wasn't transmitting, or—no. That was not it they had heard him, because they were responding. message implied but it was not necessary to "believe," only to act. say, except for one more word: Help." He grinned sourly and released the button. The message was on its way, and it would be hours before he could have a reply. Therefore he had to consider what to do next. He flushed the interior of the suit out with a reckless disregard for the wastage of his air reserve, holding his breath as much as he could, daring only shallow gasps that made him retch and gag. After a long time he could breathe, though his eyes were spilling tears. He could see the fumes in the room now. The heat was building up. Automatically—now that he had put it on and so started its concrete to do he could postpone questioning. Never mind why he had been brought here never mind how. Never mind what he would, or could, do next all those questions could recede into the background of his mind while he swung the ax and battered his way out of this poisoned oven. but flaking out in chips that left a white powdery residue. At this rate, he thought grimly, he would be an hour getting through it. Did he have an hour? it might not keep the gas and heat out, but it would retard them. evidences of use: shelves, boxy contraptions that might have been He tapped half-heartedly at one of the closed cupboards, and was not surprised when it proved as refractory as the door. Undoubtedly he could batter it open, but it was not likely that much would be left of
