Winter sun. Just past the lunar equinox. Slack tides. I walk along the Thames path into town to buy On Grammatology by Jacques Derrida. Lost the previous copy.
In front of the old Billingsgate fish market I clamber down on to the foreshore. Combing through the pebblebricks, gravel, shells, bones, pieces of clay pipe, fossils, plastic detritus and ceramic bits-and-pieces.
Notice a distinctive drift of cobalt blue Willow Pattern shards. Squat, sift and see a fragment with an image. I pick-it-up to inspect. In China there's a man on a river foreshore. I'm in a Borges story.
