<passage>:
through the darkness like tiny glowing mice, fleeing from something unknown, fleeing outwards and away toward a somewhere that was equally unknown of not-quite-darkness, and scattered throughout infinity and eternity. vast jigsaw puzzle in five dimensions, little clots and patches formed as the bits were snuggled into place here and there. The process was far from complete when Broom regained consciousness. Broom sat up abruptly and looked around him. The room was totally unfamiliar. For a moment, that seemed perfectly understandable. Why shouldn't the room look odd, after he had gone through— What? He rubbed his head and looked around more carefully. It was not just that the room itself was unfamiliar as a whole the effect was greater aware that only the pattern was different, not the details. He sat there on the floor and took stock of himself and his surroundings. some kind. It was some sort of carpeting that covered the floor from wall to wall, but no carpet had ever felt like this. He lifted himself gingerly to his feet. He wasn't hurt, at least. He He recognized, then, the emotion that had made him turn away from the objects on the table and pull his hand away from the unnatural wall. It was fear. Fear? Nonsense! He put his hand out suddenly and slapped the wall with his palm and held it there. There was nothing to be afraid of! He laughed at himself softly. He'd faced death a hundred times during the war without showing fear this was no time to start. What would his men think of him if they saw him getting shaky over the mere touch of a woodlike wall? There was a loud click! in the stillness of the room, and he leaped back from the device. He watched it warily for a moment, but nothing more seemed to be forthcoming. Still, he decided it might be best to let ... something else. What? which direction? Toward the future, obviously Contarini had made it plain that going into the past was impossible. Then could he, Broom, get back to his own time, or was he destined to stay in this—place? would come back, and he could orient himself. Meanwhile, he might as well explore his surroundings a little more. He resolved to keep his hands off anything that wasn't readily identifiable. chair was a heavy curtain which apparently covered a window. He could see a gleam of light coming through the division in the curtains. Broom decided he might as well get a good look at whatever was outside the building he was in. He stepped over, parted the curtains, and— —And gasped! building he was in was so high that it would have projected through the clouds if there had been any clouds. Broom backed away from the window and let the curtain close. He'd had all of that he could take for right now. The inside of the building, his immediate surroundings, looked almost homey after seeing that monstrous, the door that led to the other room. A picture hanging on a nearby wall caught his eye, and he stopped. It was a portrait of a man in unfamiliar, outlandish clothing, but Broom had seen odder clothing in his travels. But the thing that had stopped him was the amazing reality It wasn't, of course it was only a painting. But the lifelike, somber eyes of the man were focused directly on him. Broom decided he didn't like the effect at all, and hurried into the next room. There were several rows of the bulky tables in here, each with its own chair. Broom's footsteps sounded loud in the room, the echoes rebounding from the walls. He stopped and looked down. This floor wasn't covered with the soft carpeting well lit. For the first time, he thought of the possibility that there might be someone else here besides himself. He looked around, wishing that he had a weapon of some kind. Even a knife would have made him feel better. the room behind him, and a deeper, almost inaudible, rushing, rumbling sound that seemed to come from far below. His wish for a weapon came back, stronger than before. The very fact that he had seen no one set his nerves on edge even more than the sight of a known enemy would have done. He was suddenly no longer interested in his surroundings. He felt they might tell him where he was. Carefully, he grasped the handle of the door, twisted it, and pulled. The body experiences, but does not see. Only the soul is capable of knowing eternity." Broom outranked the little Italian, but prison can make brothers of all men. "You think it's possible then, to get out of a place like this, simply by thinking about it?" Broom held back a grin. "Then why, my Venetian friend, have you not left this place long since?" "I try," Contarini had said simply, "but I cannot do it. You wish to know why? It is because I am afraid." "Afraid?" Broom raised an eyebrow. He had seen Contarini on the battlefield, dealing death in hand-to-hand combat, and the Italian hadn't impressed him as a coward. this, I have a great fear. Only a saint can handle such things, and I am no saint." "I hope, my dear Contarini," Broom said dryly, "that you are not under the impression that I friend I'll try it. What's your first lesson?" The memory faded from Broom's mind. Had he really moved through some segment of Eternity to reach this ... this place? Had he— He felt a chill run through him. What was he doing here? How could he Instinctively, he turned and ran back toward the room he had left. If he got back to the place where he had appeared in this world, perhaps—somehow—some force would return him to where he belonged. The door was as he had left it, the porcelain dish still in place. He scooped up the dish in one big hand and ran on into the room, letting the door shut itself behind him. He ran on, through the large room with concentration, trying to bring back a memory that would not come. He did not hear the intruder until the man's voice echoed in the room. Broom's eyes opened, and instantly every muscle and nerve in his hard-trained body tensed for action. There was a man standing in the doorway of the office. He was not a particularly impressive man, in spite of the queer cut of his clothes. He was not as tall as Broom, and he looked soft and overfed. His paunch protruded roundly from the open front of the short coat, and there was a fleshiness about his face that betrayed too much And he looked even more frightened than Broom had been a few minutes before. He was saying something in a language that Broom did not understand, and the tenseness in his voice betrayed his fear. Broom relaxed. He had nothing to fear from this little man. "I won't hurt you," Broom said. "I had no intention of intruding on your property, but all I ask is help." The little man was blinking and backing away, as though he were going to turn and bolt at any moment. Broom laughed. "You have nothing to fear from me, little man. Permit me to introduce myself. I am Richard Broom, known as—" He stopped, and his eyes widened. Total memory flooded over him as he realized fully who he was and where he belonged. And the fear hit him again in a raging flood, sweeping over his mind and Of that there can be no doubt. Why did you return?" Richard Broom sat up on his palette of straw. The scene in the strange building already seemed dreamlike, but the fear was still there. "I couldn't remember," he said softly. "I couldn't remember who I was nor little dizzy—I was pretty shocked, you know. To be honest, I didn't see where he went. I must have fainted. "But I think you can pick him up if you hurry. With that getup on, he He cradled the phone, pulled a handkerchief from his pocket, and dabbed at his damp forehead. He was a very frightened little man, but he knew he'd get over it by morning.
