She returned to the street and shivered as a chill gust of wind cut through her thin clothes. The quickest way to Soho would mean turning left and heading back to the main road where she could pick up a bus. Which would be what they were expecting her to do. So she turned right and walked briskly towards the end of the street. From her earlier reconnaissance, Carol knew she could cut through the warren of back streets to a short alley between some shops that would bring her out on the other side of Stoke Newington, from where she could catch a train. They wouldn’t be expecting that, she reckoned.

At the corner, she quickened her pace to a trot, hoping to make the next corner before whoever was on her tail could catch up with her. She crossed into the next street, pulling the kagoule out of her bag as she went. Her next turning was almost upon her, and she swung quickly into a gateway, pulling the kagoule over her head and jamming the baseball cap over her blonde hair. Then she walked back into the street, this time adopting a slow, swaggering walk, as if she had all the time in the world.

When she reached the junction, she glanced over her shoulder. Nobody in sight apart from an elderly man clutching a supermarket carrier bag and shuffling down the opposite side of the street. Which meant nothing, she knew. She couldn’t allow herself to act as if she’d shaken off her pursuit.

Now the entrance to the alley was in sight. It was a narrow passage between high brick walls, easy to miss if you didn’t know it was there. With the adrenaline surge of relief, Carol turned into its gloomy mouth.

She was about a third of the way down when she realized she’d made a bad mistake. Heading towards her were two young men. There wasn’t quite enough room for them to walk side by side, but they were so close together she couldn’t possibly pass them. They looked like thugs; but these days, most men in their late teens and early twenties did. Carol found herself wondering, idiotically, when exactly it had become fashionable for respectable lads to look like potential muggers. This pair fit the identikit mould perfectly. Heads shaved to stubble, waterproof Nike jackets over football shirts, chinos and Doc Martens. There was nothing to distinguish them from thousands of others. Maybe that’s the point, she thought as they approached inexorably.
