【正文】 t looked well on the vidsc reens. The redgolden lion39。s mane of hair framed a face that was youthful, handsome, earnest, intense. His godlike looks, his vibrant personality all were rapidly making a reluctant deity of a very mortal young man. But I tell you, Mr. Warden, and I tell my people that I would not be here now, I would not be wearing this crown, the galaxy would not be at peace today, if it were not for the sacrifices of Lord Derek Sagan. He attempted to correct the great wrongs he had done and, in so doing, gave his life that others might live. He is one of the greatest men I have ever known. I will always honor his memory. Bosk tossed the remainder of the jumpjuice at the vidscreen. Here39。s that for his fuc kin39。 memory. The juice tric kled down the screen, soa ked into the threadbare carpet which covered the floor of the shabby studio apartment. A crisp knock sounded on the door. Lurching to his feet, Bosk went to answer it. On his way, he made a detour to the bottle, poured himself another drink. Reach ing the door, he peeped out the oneway peephole, saw a man dressed in a suit, carrying a briefcase. The man didn39。t look threatening. He didn39。t look anything. He had one of those faces you meet and five minutes later you can39。t recall ever having be en introduced to him before. Bosk was more interested in the briefcase. It is said that Adonians can smell money. Bosk39。s nose twitched. He opened the door. Yeah? he said, looking first at the briefcase, then finally lifting his gaze to meet the stranger39。s. What39。s the deal? I don39。t be lieve it would be wise for us to conduct our business in the hallway, the stranger said. He wasn39。t even breathing hard after the long climb. He smiled in a pleasant and disarming manner. Your neighbors don39。t need to know your affairs, do they? Bosk followed the stranger39。s glance, saw Mrs. Kasper standing in her halfopen door. He glared at her. I heard a knock, she said defensively. Thought it might be for me. She sniffed. Another of your 39。clients39。? Nosy old bitch! Bosk retorted. He opened his own door wider. C39。mon in, then. The stranger entered. Bosk shut the door, took a look out the peephole to ma ke sure Mrs. Kasper had gone back into her apartment. She had a bad habit of loitering in the hall, listening outside closed doors. Sure enough. Bosk flung the door open, nearly knocking Mrs. Kasper down. Care to join us? He leered. Disgusted, she flounced back inside her apartment and slammed her door. Bosk shut his door again, turned around to face his guest. T he stranger was tall, wellbuilt, handsome if you went for older guys with hair graying at the temples, which Bosk did not. T he clothes were expensive but not ostentatious. Snaga Ohme would have approved the choice of colors: muted blues and grays. The face was a ma sk. The lines and wr inkles had been trained to betray nothing of the thoughts within. The eyes were oneway mirrors. Bosk looked in, saw himself reflected back. Having once been close to some of the most powerful people in the galaxy, Bosk recognized and appreciated the quiet air of co ntrol and authority this man exuded, like a fine cologne that never overwhelms, never cloys the senses. I assume that you are the Adonian known as Bosk? The stranger was polite. I39。m an Adonian and my name39。s Bosk. That answer your questions? Not all of them. The stranger continued to be polite. Were you once in the employ of the late Snaga Ohme, former weapons dealer? Bosk swallowed. I wasn39。t in his 39。employ,39。 mister! I was his goddamn friend! His best friend. He trusted me, more39。n anyone. H e trusted me. I knew ... all his secrets. Bosk brushed his hand across his eyes, wiped his nose with his fingers. Adonians are a sensitive race, who have a tendency to get maudlin w hen they39。re drunk. I was his confidant. Me. Not those other fops, those pretty boysfawn39。lng and preening. And the women. They were the worst. But he loved me. He loved me. Bosk drained the glassful of jumpjuice. The stranger nodded. Yes, that is consistent with my information. Snaga Ohme told you all his secrets. He even told you about his project codenamed Negative Waves. Maybe, maybe not. Bosk eyed the stranger warily. You want a drink? No, thank you. Mind if I sit down? Suit yourself. Bosk wandered back to the bottle. The stranger walked across the small room. Bosk watched him out of the corner of his eye. The stranger39。s movements were fluid, controlled. He was in excelle nt physical condition, with a hardmuscled body, good reflexes. Pity he39。s not twenty years younger, Bosk thought. The stranger pulled up a battered metal foldout chairone of the few articles of furniture in the apartment. In front of the chair was a puter. A highly sophisticated and expensive personal puter, it looked considerably out of place in the poverty stricken surroundings. The stranger seated himself in the chair, regarded the puter with admiration. That39。s a fine setup, Bosk. Probably worth the price of this whole apartment building. I39。d sell myself first, Bosk said sullenly. He had sold himself first, but that was beside the point. He hunched bac k down in the recliner. Snaga Ohme gave that puter to me. It39。s one of the best, the fastest in the whole damn galaxy. A photograph of Snaga Ohmebronze, beautiful, as were most Adoniansstood in an honored place beside the crystalline storage lattice. The stranger nodded, smiled in sympathy, placed the briefcase on his knees, and waited for Bosk to resume talking. But Bosk39。s attention had been recaptured by the vidscreen. The king was speakin
