I stood on the old ferry dock and watched the icy sludge slide by. Patches of white ice slipped through, but mostly it was grey slush, sluggish and heavy looking. The air was sharp and clear, one of the few benefits of the evacuation and reducing temperature, the centuries-old odour of industry and modern life frozen and discarded, leaving a crispness previously only found among the peaks of mountain ranges. On the far bank stood the ruins of Birkenhead, where the riots had been particularly bad and the fires that followed were allowed to rage out of control. It had taken weeks for the conflagration to finally die, leaving behind soot-blackened husks of buildings, grotesque sculptures of melted glass and metal and more dead than anyone ever cared to count.
