THURSDAY

Simmons, regional manager for a chain of high street discount stores, slipped his change into his pocket then neatly folded his newspaper in half and tucked it under his arm. He quickly glanced at his watch before leaving the shop and rejoining the faceless mass of shoppers and office workers crowding the city centre pavements outside. He checked through his diary in his head as he walked. Weekly sales meeting at ten, business review with Jack Staynes at eleven, lunch with a supplier at one-thirty...

He stopped walking when he saw her. At first she was just another face on the street, nondescript and unimposing and as irrelevant to him as the rest of them were. But there was something different about this particular woman, something which made him feel uneasy. In a split-second she was gone again, swallowed up by the crowds. He looked round for her anxiously, desperate to find her amongst the constantly weaving mass of figures which scurried busily around him. There she was. Through a momentary gap in the bodies he could see her coming towards him. No more than five feet tall, hunched forward and wearing a faded red raincoat. Her wiry grey-white hair was held in place under a clear plastic rain-hood and she stared ahead through the thick lenses of her wide rimmed glasses. She had to be eighty if she was a day he thought as he looked into her wrinkled, liver-spotted face, so why was she such a threat? He had to act quickly before she disappeared again. He couldn't risk losing her. For the first time he made direct eye contact with her and he knew immediately that he had to do it. He had no choice. He had to do it and he had to do it right now.

Dropping his newspaper, briefcase and umbrella Simmons pushed his way through the crowd then reached out and grabbed hold of her by the wide lapels of her raincoat. Before she could react to what was happening he spun her round through almost a complete turn and threw her back towards the building he'd just left. Her frail body was light and she virtually flew across the footpath, her feet barely touching the ground before she smashed up against the thick safety-glass shop window and bounced back into the street. Stunned with pain and surprise she lay face down on the cold, rain-soaked pavement, too shocked to move. Simmons pushed his way back towards her, barging through a small crowd of concerned shoppers who had stopped to help. Ignoring their angry protests he dragged her to her feet and shoved her towards the shop window again, her head whipping back on her shoulders as she clattered against the glass for the second time.

'What the hell are you doing, you idiot?!' an appalled bystander yelled, grabbing hold of Simmons' coat sleeve and pulling him back. Simmons twisted and squirmed free from the man's grip. He tripped and landed on his hands and knees in the gutter. She was still on her feet just ahead of him. He could see her through the legs of the other people crowding around her.

Oblivious to the howls and screams of protest ringing in his ears, Simmons quickly stood up, pausing only to pick up his umbrella from the edge of the footpath and to push his wire-framed glasses back up the bridge of his nose. Holding the umbrella out in front of him like a bayonet rifle he ran at the woman again.

'Please...' she begged as he sunk the sharp metal tip of the umbrella deep into her gut and then yanked it out again. She slumped back against the window, clutching the wound as the stunned and disbelieving crowd quickly engulfed Simmons. Through the confusion he watched as her legs gave way and she collapsed heavily to the ground, blood oozing out of the deep hole in her side.

'Maniac,' someone spat in his ear. Simmons span around and stared at the owner of the voice. Jesus Christ, another one! This one was just like the old woman. And there's another, and another... and they were all around him now. He stared helplessly into the sea of angry faces which surrounded him. They were all the same. Every last one of them had suddenly become a threat to him. He knew there were too many of them but he had to fight. In desperation he screwed his hand into a fist and swung it into the nearest face. As a teenage boy recoiled from the sudden impact and dropped to the ground a horde of uniformed figures weaved through the crowd and wrestled Simmons to the ground.
