Late February and the air is already full of spring, too early; worry caused by mild weather. At the harbour, the asphalt plant shimmers in a misted haze coming off the waters of the Thames estuary. The water is at low ebb, slutch visible, glistening. The sun is bright and the mist has a chilled bite. A sky unclouded, deep tangible blue. The world is unfocused, either fading in or fading out. You imagine things appearing or slipping out of view forever in the mist; a sea-giant made of salt spray and coastal haze. But nothing ever does.
