There is no need to believe in headless horseman and ghostly apparitions when steel and chrome can move so mysteriously in the night. In Hammer horror films they lock the doors and close the shutters to protect themselves from the undead; In the 21st century we do the same but to protect ourselves from our fellows.
Maybe the supernatural has updated itself for modern times and instead of the Flying Dutchman and spectral Carriages we have broken bicycles; only we have innoculated ourselves with countless viewings of Nightmare on Elm Street and the Texas Chain Saw Massacre and no longer can recognise the marvellous. Or maybe the manmade horrors of Darfur is more horrifying than anything the spirit world can produce.
Six hours later it has moved down the road under the cloak of darkness. By the next night it will probably be in the river. By coincidence that day I heard Jeremy Hardy on the radio say "Pavements are for pedestrians, roads are for cars and canals are for bicycles"
