Christmas Time
The body had turned purple by the time it was found after the holiday, not actually rotten, but not very pleasant. No one seemed to know who the person was, he was just another of the numerous homeless who lived (and died) on the streets. Few people took any notice of them at the best of times and in the holiday season most people found their presence worrying; best to pretend they did not exist or that someone else was going to look after them. The death rate had a yearly peak in mid winter, especially in a cold winter, but outside the official almanacs it was a matter of no interest. In a selfish world who really cared about others who had a simply yearn for a warm bed and a good meal? The eventual result of the death was an overwhelming apathy that was quickly forgotten.
