<passage>:
Mercury, he was selling his guns into the weirdest of all his exploits—gambling his life against the soft touch of a woman's lips. She bent her head in acknowledgment so that her bronze red hair fell down about her face. There was perspiration on her upper lip and temples. Her crimson mouth wore a fixed smile. Her eyes were frightened. The man, who had accompanied the singer on the piano, sat at the foot the singer but kept his pale, immature face bent over the keys, while his fingers lightly, automatically picked out the tune. Sweat trickled down the back of his neck, plastered his white coat to his back. Without looking up, he said: "Have you spotted him?" His voice was pitched to reach the singer alone. The girl, with an almost imperceptible gesture, shook her head. The night was very hot stiffened. "Here he is," she said to the pianist without moving her lips. The pianist swung around on his stool, lifted his black eyes to the "Go on," said the pianist in a flat voice. The red-head shivered. Stepping from the stage she picked her way "you have come. I did not think you would be in time." Her hands were clenched in her lap. The knuckles were white. The man said nothing. she had used his name. "You have the reputation of being unpredictable. I don't trust you, but since...." She stopped as the waiter placed glasses on the table and deftly poured compelling note. His eyes, light blue and amused, were pale against his brown face. The girl drew in her breath. The girl started, glanced at the pianist, said with a shiver: "We can't locate Karfial Hodes. Don't look at me that way, Jaro. You frighten me. I'm telling the truth. We can't find him. That's why we called you. "No," the girl replied. "But we think he's here in the city." "Why? What makes you think that?" "He was seen," she began, then stopped with a gasp. The lights had gone out. It was as unexpected as a shot in the back. One moment the garden was he could sense it. An exclamation was suddenly choked off as if a hand had been clamped over the girl's mouth. "Red!" said Jaro in a low voice. There was no answer. "Red!" he repeated, louder. He wondered who was putting up the ten thousand Earth notes? Who stood to lose most in case of a revolution? The answer seemed obvious enough. Who, but Albert Peet. Peet controlled the Latonka trade for which there was a tremendous demand throughout the Universe. And what had happened to the girl. Had the rebels abducted her. If so, he suspected that they had caught a tartar. The Red Witch had the reputation of being able to take care of herself. He beckoned a waiter, paid his bill. As the Mercurian started to leave, a thought struck Jaro. These yellow-eyed Mercurians could see as well in the dark as any alley-prowling cat. For centuries they had lived Jaro shrugged, dismissed the waiter. He had not expected to get much information from the waiter, but he was not a man to overlook any possibility. If the girl had been abducted, only Mercurians could have engineered it in the dark either side: buildings with walls four feet thick to keep out the heat of the sun. Beneath his feet, he knew, stretched a labyrinth of rooms and passages. Somewhere in those rat-runs was Karfial Hodes, the revolutionist, and the girl. following him. They were never visible, but to his trained ears there came stealthy, revealing noises: the brush of cloth against the baked earth walls, the sly shuffle of a step. He ducked down a bisecting But as soon as he emerged he was conscious again of the followers. In the dense, humid night, he was like a blind man trying to elude the cat-eyed Mercurians. interest. He had, he supposed, killed rather a lot of men. He had fought in was little doubt but that he had killed quite a number of men. But this business of hunting a man through the rat-runs beneath the city was out of his line. Furthermore, there was something phony about the entire set up. speculation. He swung his bare feet over the edge of the bed, stood up and ground out his cigarette. Before he could reach the door the rapping came again. matter. I preferred to remain behind the scenes, but the disappearance of Miss Mikail has—ah—forced my hand." He paused. Jaro still said nothing. Miss Mikail must be the red-headed singer, whom at different times he had known under a dozen different aliases. He doubted that even she remembered her right name. "Miss Mikail made you a proposition?" Albert Peet's voice was tight. "Why, no. As it happened she was abducted before I had the chance." Mr. Peet licked his lips. "But you will, surely you will. Unless "Perhaps. I have a large interest in the Latonka trade. It is—ah—lucrative." Jaro Moynahan lit a cigarette, sat down on the edge of the bed. "Why Jaro laughed. "How did you know Red had been kidnapped?" "We have a very efficient information system. I had the report of Miss Mikail's abduction fifteen minutes after the fact." Jaro raised his eyebrows. "Perhaps then you know where she is?" Mr. Peet shook his head. "No. Karfial Hodes' men abducted her." A second rapping at the door caused them to exchange glances. Jaro went Moynahan he froze. "What're you sneaking around here for?" Jaro settled himself warily, his light blue eyes flicking over the youth. "Let's get this straight," he said mildly. "I've known your kind before. Frankly, ever since I saw you I've had to repress a desire to step on you as I might a spider." anyone called a doctor? Where's Miss Webb? Miss Webb! Oh, Miss Webb! right. She had straight black hair which hung not quite to her shoulders, and dark brown eyes, and enough of everything else to absorb Jaro's attention. "Oh!" exclaimed Miss Webb as she caught sight of the blood staining the carpet. "Call a doctor, Miss Webb." Miss Webb raised an eyebrow, went to the visoscreen. In a moment she Miss Webb's eyes grew round as marbles. "I wouldn't touch one of those nasty little contraptions for all the Latonka on Mercury." the first grog shop you come to." Miss Webb raised her eyebrows. "What's this? A new technique?" There's something I must know. It's important." He cleared his throat. "Don't you find the heat rather uncomfortable, Miss Webb. But perhaps you've become accustomed to it." "Goodbye, Miss Webb," said Mr. Peet firmly. first basement grog shop he turned in. His eyes swept the chamber, then " said Jaro coming up behind her and poking a long brown finger in the small of her back. Miss Webb uttered a shriek, jerked so violently that her hat tilted over one eye. She regarded him balefully from beneath the brim. "Never a dull moment," she gritted. Still grinning, Jaro sat down. "I'm Jaro Moynahan, Miss Webb. I think Jaro's order. "All right," Jaro smiled, but his pale blue eyes probed the girl thoughtfully. "I'll have to confide certain facts which might be dangerous for you to know. Are you game, Miss Webb?" "Since we're going to be so chummy," she replied "It's not true," Joan flared. "It's all a pack of lies invented by the Latonka Trust. I know." "But I should think rumors like that would run down the Latonka stock."
