<passage>:
His name was Liam O'Leary and there was something stinking in his nostrils. It was the smell of trouble. He hadn't found what the trouble its inmates as the Jug—and if he hadn't been able to detect the scent of trouble brewing a cell-block away, he would never have survived to reach his captaincy. The girl lifted her head angrily and took a step forward. The block guard, Sodaro, growled warningly: "Watch it, auntie!" O'Leary shook his head. "Let her talk, Sodaro." It said in the Civil Service Guide to Prison Administration : "Detainees will be permitted to speak in their own behalf in disciplinary proceedings." And O'Leary was a man who lived by the book. offense. Look at the rap sheet. Yesterday she pulled the same thing in the mess hall." He shook his head reprovingly at the prisoner. "The warned her then that next time she'd get the Greensleeves for sure." Inmate Bradley seemed to be on the verge of tears. She said tautly: "I don't care. I don't care!" O'Leary stopped her. "That's enough! Three days in Block O!" It was the only thing to do—for her own sake as much as for his. He had managed, by strength of will, not to hear that she had omitted violate the Categoried Class laws. Don't waste your time with her, Cap'n. She's a figger-lover!" Captain O'Leary took a long drink of water from the fountain marked enforcement of a demonstrable fact. "Evening, Cap'n." A bleary old inmate orderly stood up straight and touched his cap as O'Leary passed by. "Evening." O'Leary noted, with the part of his mind that always noted those things, that the orderly had been leaning on his broom until he'd noticed the captain coming by. Of course, there wasn't much to next hour, languidly poking a piece of fluff out of the air filter on the prison jeep. Lazy, sure. Undependable, certainly. But he kept the cars going—and, O'Leary thought approvingly, when his sentence was up And punishment is what you get. Block O in Estates-General Correctional Institution was the disciplinary block, and because of the green straitjackets its irritable guard, climbing the steel steps toward Block O from the floor company." He laughed coarsely and abandoned his charges to the Block O guards. The outside guard said sourly: "A woman, for God's sake. Now O'Leary long. III "I smell trouble," said O'Leary to the warden. "Trouble? Trouble?" Warden Schluckebier clutched his throat and his little round eyes looked terrified—as perhaps they should have. Warden trouble?" O'Leary shrugged. "Different things. You know Lafon, from Block A? This afternoon, he was playing ball with the laundry orderlies in the yard." The warden, faintly relieved, faintly annoyed, scolded: "O'Leary, what did you want to worry me for? There's nothing wrong with playing ball in the yard. That's what recreation periods are for." don't mix it isn't natural. And there are other things." O'Leary hesitated, frowning. How could you explain to the warden that it didn't smell told Bradley to mop up in wipe talk and Bradley didn't understand. Now Mathias wouldn't—" The warden raised his hand. "Please, O'Leary, don't bother me about that kind of stuff." He sighed heavily and rubbed his eyes. He poured himself a cup of steaming black coffee from a brewpot, reached in a desk drawer for something, hesitated, glanced at O'Leary, then dropped a pale blue tablet into the cup. He drank it down eagerly, ignoring the scalding heat. He leaned back, looking suddenly happier and much more assured. "O'Leary, you're a guard captain, right? And I'm your warden. You have your job, keeping the inmates in line, and I have mine. Now your job is just as important as my job," he said piously. " ." O'Leary snapped erect, abruptly angry. Pass! What the devil way was that for the warden to talk to him? "Excuse the expression, O'Leary," the warden said anxiously. "I mean, after all, 'Specialization is the goal of civilization,' right?" He was a great man for platitudes, was Warden Schluckebier. " . You see?" And he folded his hands and smiled like a civil-service Buddha. O'Leary choked back his temper. "Warden, I'm telling you that there's trouble coming up. I smell the signs." "Handle it, then!" snapped the warden, irritated at last. "But suppose it's too big to handle. Suppose—" "It isn't," the warden said positively. "Don't borrow trouble with all your supposing, O'Leary." He sipped the remains of his coffee, made a wry face, poured a fresh cup and, with an elaborate show of not noticing what he was doing, dropped three of the pale blue tablets into He sat beaming into space, waiting for the jolt to take effect. "Well, then," he said at last. "You just remember what I've told you tonight, O'Leary, and we'll get along fine. 'Specialization is the—' Oh, curse the thing." His phone was ringing. The warden picked it up irritably. That was the trouble with those pale blue tablets, thought O'Leary they gave you a lift, but they put you on edge. "Hello," barked the warden, not even glancing at the viewscreen. "What the devil do you want? Don't you know I'm—What? You did Whatever he saw on it, it did not reassure him. His eyes opened like clamshells in a steamer. "O'Leary," he said faintly, "my mistake." And he hung up—more or less by accident the handset dropped from his underprivileged clerk, she told herself, conscience-stricken. Across the hall, the guard was saying irritably: "What the hell's the matter with you?" He opened the door of the cell with an get all the way around Block O and the inmates complained like crazy if he didn't make sure they all got the most possible free time. He was and the blister against his abdomen, where the shiv had been hidden during other rest periods, felt like raw acid. "All right," whispered Flock, "just walk out the door and you won't get hurt. Unless the other screw makes trouble, you won't get hurt, so tell him not to, you hear?" He didn't let go. And he didn't stop. IV It was Flock on the phone to the warden—Flock with his eyes still voice was a cheerful bray, though the serpent eyes were cold and hating. "Warden, you got to get a medic in here. My boy Flock, he hurt himself real bad and he needs a doctor." He gestured playfully at the guards with the shiv. "I tell you, Warden. I got this knife and I got your guards here. Enough said? So get a medic in here quick, you hear?" And he snapped the connection. O'Leary said: "Warden, I told you I smelled trouble!" The warden lifted his head, glared, started feebly to speak, hesitated, and picked up the long-distance phone. He said sadly to the prison
