the tanker driver's face. The middle-aged man's face was pressed hard against the shattered glass of his side window, frozen in an expression of terrified agony. Dark red blood dribbled freely down his chin, contrasting starkly with the rest of his blanched white face. The executive's car ploughed into Sonya at speed, sending her flying back in her seat and then lurching forward awkwardly. Consumed by a sudden wave of nauseating pain as her distended belly and her baby were momentarily crushed again, she briefly lost consciousness.
In the few minutes that Sonya was unconscious the world around her changed almost beyond all recognition. She slowly woke and cautiously half-opened her eyes. Slumped heavily forward with her face pressed hard against the steering wheel she pushed herself upright, struggling for a moment with the weight of her unborn child. Her own safety was of no concern as, for a few seconds longer, she remained still and closed her eyes again, running her hands over her tender belly until she was sure she had felt the reassuring movements of the baby inside. Her split-second feelings of relief and elation were immediately forgotten when she lifted her head again and looked around.
Apart from the occasional hissing jet of steam rising up into the morning air and smoke and flame from numerous burning vehicles, the world was completely silent and still. Nothing moved. Where she had expected to hear voices and cries for help there was nothing.
Sonya instinctively tried to open the door to get out of her wrecked car. Another crashed car to her right, however, had wedged it shut and she was unable to force it open any more than just a couple of centimetres. The van which had collided with her on the other side prevented her from opening the passenger door. The sunroof seemed the only safe escape route. Suddenly freezing cold and shaking with shock and nervous fear she turned the key in the ignition far enough for her to be able to use the electrics of her disabled car. She lifted a trembling hand and operated the control which opened the sunroof. The sudden, jerking noise sounded disproportionately loud in the oppressively silent vacuum of the grey morning. The tinted window above her slid open before stopping with a heavy thud. Slowly lifting herself up onto her clumsy, unsteady feet she guided her head and shoulders out through the restrictive rectangular opening. She cautiously stood upright on her seat and waited for a moment and wriggled her toes, water retention having swollen her tired feet and ankles. She lifted her arms out of the car and then eased and squeezed her pregnant stomach through the rubber-lined gap. Her arms weak and heavy with nerves, she put the palms of her hands flat on the roof of the car and pushed herself up and out. A few seconds of grunting and straining and she had moved far enough to be able to sit on top of her wrecked vehicle. For a while she just sat there in stunned disbelief and surveyed the silent devastation around her. The carnage seemed endless and without any apparent reason.
The motorway around her was dead in both directions. Whatever had happened had worked its way back along the wide road towards the city. Sonya carefully shuffled around so that she was looking back towards the collection of tall, imposing buildings which she had driven through little more than three-quarters of an hour earlier. For as far as she could see both ahead and behind her the traffic on the motorway was motionless. She deliberately tried not to look too closely at any of the wrecked vehicles although it was hard not to stare. Their drivers were dead. Some remained sat in their seats, frozen and lifeless. Some were burning. Others appeared to have suffered a more violent and inexplicable fate. Many twisted and bloodied corpses lay on the ground in the random gaps between the wrecks of their cars, tankers, lorries, bikes and vans.
A cold autumnal wind gusted along the
