My grandmother Elizabeth (or Gan-Gan as I called her) was a force of nature; she was wonderful. As a child she seemed to me like a visitor from another time or place. Her tiny terraced house in Bideford was full of treasures; hundreds of books, a medusa's head, Peter the Great's ivory letter opener, the caul of her mother tied up in blue ribbon, a tile stolen from the Alhambra, a silk blouse embroidered by nuns, deadly poison, beautiful Pre-Raphaelite artworks, a knife carved from the wood of HMS Victory, Granny Green's pince-nez, and diaries full of stories from a hard life well-lived. After her death in 2010, I helped my father and uncle sort through some of her possessions. I inherited some of her clothes to wear, books to read, a bicycle to ride. But how do you make sense of all the other things that someone leaves behind, the things nobody sees, boxes full of photographs, and bits of string?
