Sue-Ann Bradley looked carefully at the floor and paid them no attention. The outside guard pulled the switch that turned on the 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. Sue-Ann walked bravely forward through the opened gate--and fell flat on her face. It was her first experience of a tanglefoot field. It was like walking through molasses. The guard guffawed and lifted her up by one shoulder. "Take it easy, auntie. Come on, get in your cell." He steered her in the right direction and pointed to a greensleeved straitjacket on the cell cot. "Put that on. Being as you're a lady, we won't tie it up, but the rules say you got to wear it and the rules--Hey. She's crying!" He shook his head, marveling. It was the first time he had ever seen a prisoner cry in the Greensleeves. However, he was wrong. Sue-Ann's shoulders were shaking, but not from tears. Sue-Ann Bradley had got a good look at Sauer and at Flock as she passed them by and she was fighting off an almost uncontrollable urge to retch. * * * * * Sauer and Flock were what are called prison wolves. They were laborers--"wipes," for short--or, at any rate, they had been once. They had spent so much time in prisons that it was sometimes hard even for them to remember what they really were, outside. Sauer was a big, grinning redhead with eyes like a water moccasin. Flock was a lithe five-footer with the build of a water moccasin--and the sad, stupid eyes of a calf. Sauer stopped yelling for a moment. "Hey, Flock!" "What do you want, Sauer?" called Flock from his own cell. "We got a lady with us! Maybe we ought to cut out this yelling so as not to disturb the lady!" He screeched with howling, maniacal laughter. "Anyway, if we don't cut this out, they'll get us in trouble, Flock!" "Oh, you think so?" shrieked Flock. "Jeez, I wish you hadn't said that, Sauer. You got me scared! I'm so scared, I'm gonna have to yell!" The howling started all over again. The inside guard finished putting the new prisoners away and turned off the tangler field once more. He licked his lips. "Say, you want to take a turn in here for a while?" "Uh-uh." The outside guard shook his head. "You're yellow," the inside guard said moodily. "Ah, I don't know why I don't quit this lousy job. Hey, you! Pipe down or I'll come in and beat your head off!" "Ee-ee-ee!" screamed Sauer in a shrill falsetto. "I'm scared!" Then he grinned at the guard, all but his water-moccasin eyes. "Don't you know you can't hurt a wipe by hitting him on the head, Boss?" "Shut _up_!" yelled the inside guard.
