<passage>:
I 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 was yet, but he would. That was his business. He was a captain of 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. disciplinary block help straighten her out? He rubbed his ear and looked past her at the line of prisoners on the rap detail, waiting for him to judge their cases. 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 Captain O'Leary took a long drink of water from the fountain marked yard, wondering about her. She'd had every advantage—decent Civil Service parents, a good education, everything a girl could wish for. If anything, she had had a better environment than O'Leary himself, and 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 sweep—the spray machines and sweeperdozers had been over the cobblestones of the yard twice already that day. But it was an inmate's job to keep busy. And it was a guard captain's job to notice when they Conan, now—he was a big buck greaser and he would be there for the 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 in another year or so, he would go back to his life with his status Block O in Estates-General Correctional Institution was the irritable guard, climbing the steel steps toward Block O from the floor The inside guard muttered: "Wipe rats! They're getting on my nerves." 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 tanglefoot electronic fields that swamped the floor of the block corridor and of each individual cell. While the fields were on, you could ignore the prisoners—they simply could not move fast enough, against the electronic drag of the field, to do any harm. But it was a rule that, even in Block O, you didn't leave the tangler fields on all the time—only when the cell doors had to be opened or a prisoner's restraining garment removed. 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? What 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 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 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 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 Greensleeves. Ten minutes out of every two hours, even the worst case had to be allowed to take his hands out of the restraining garment. "Rest period" it was called—in the rule book. The inmates had a less 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 let the stinking wipe take care of his own troubles. He only had ten minutes to 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 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 streaming tears, Flock with Sauer standing right behind him, menacing the two bound deck guards. 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 and yawned and worried. An alert! The older kids fussed and complained and their mothers shut them up. No, there wasn't any alert scheduled
