 Why did Sauer and Flock yell so much?
She was in a detachment of three unfortunates like herself, convoyed by an irritable guard, climbing the steel steps toward Block O from the floor below, when she heard the yelling. "Owoo-o-o," screamed Sauer from one end of the cell block and "Yow-w-w!" shrieked Flock at the other. 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. "What do you want, Sauer?" called Flock from his own cell. The crazy yowling of the hard-timers, Sauer and Flock, was getting under her skin.
