until it is stopped and then alters direction and continues to move again.
Although animated, the cadaver remains otherwise lifeless and oblivious to its surroundings. It is ignorant to its physical limitations. The body is continuing to decay and the lack of a functioning circulatory system is beginning to cause movement problems. Gravity has steadily pulled the body's internal contents downwards. Blood has swollen its already clumsy hands and feet. It's bowels are slowly and involuntarily evacuating. The face, already tinged with the blue-green hue of decay, is otherwise drained of colour.
Until now the body's nervous system has been operating at a massively reduced level, and the corpse is oblivious to changes in its surroundings such as temperature, humidity and light levels. Several hours ago its clothing became snagged and torn after becoming entangled with the wheel of an upturned shopping trolley. The body's once smart black skirt is now just a rag wrapped around its right foot. It has also lost one of its shoes which causes its awkward gait to become even more clumsy and unsteady.
The corpse does not respire, nor does it have any need to eat or drink or seek shelter or protection. There is, however, still some activity in the centre of the brain which facilitates some basic functionality. The eyes and ears operate at a massively reduced level. It can see and hear, although it is presently unable to interpret and understand the information it absorbs. As the rest of the body continues to deteriorate, however, the part of the brain least affected by the infection is beginning to re-establish itself, albeit at a desperately slow rate.
Less than three hundred meters away from the corpse's present location the front of another building has collapsed. Initially damaged by a truck which plunged off an elevated section of road when its driver became infected, the weakened structure has now crumbled and caved in on itself, producing huge amounts of dust and substantial vibrations and noise. Amy Steadman's body, although not understanding what the disturbance is, has instinctively altered direction and is beginning to move towards it.
It is just before eight o'clock in the morning and the building where Amy died has now been in almost total darkness for more than twelve hours. With no electricity, almost all of the visible light comes from the windows in and around the main entrance doors which the body is now moving towards. It does not realise that this is an exit, but it gravitates towards the doors because of the comparative level of brightness there and also the fact that the sound and vibrations from the building collapse emanated from that general direction. Three of the four main doors are blocked. Still drawn to the brightness outside, instead of turning and moving away when it reaches the glass, Amy's body now shuffles clumsily from side to side until it finally reaches the single open door and trips outside.
The body is ignorant to the sudden change in its surroundings. It is noticeably cooler outside and it has been raining steadily for the last two hours. A strong westerly wind is gusting across the front of the building that the corpse has just emerged from, and the sudden strength of the wind is sufficient to knock the comparatively weak body off course. The cloud of dust which was thrown up by the collapse of the second building is steadily being washed down by the rain, causing the entire scene to become covered in a light layer of grey dirt and mud. The noise and vibrations have faded now and there remains no noticeable indication of the previous disturbance. Without any obvious visual or auditory distractions, Amy Steadman's corpse begins to move randomly again, shuffling slowly forward until it can go no further and then turning and moving away.
Several hours have now passed.
The corpse has now moved more than half a mile from the building where it was infected and killed. It has continued to make constant but slow and directionless progress. Its dulled eyes have gradually become accustomed to the light levels outdoors. Additionally the rain has now stopped and the scene has brightened. Previously only able to see clear, obvious movements and stark differences in light levels, the sodden corpse is now able to distinguish a finer level of detail and is aware of more subtle changes around its immediate vicinity. There are other bodies nearby. Amy's cadaver is now able to see their movements from a distance of around ten
