I should have said that I also went last night to see Charlotte Verity’s exhibition in Purdy Hicks, which has left the backstreets of Southwark for a smart new gallery nearly opposite South Kensington tube.   Seeing the pictures in a very crowded room was nearly the worst way of appreciating the quiet and meditative qualities of her pictures of plants and branches in the winter sun, but I have at least been able to enjoy the book which has been produced alongside the exhibition with short tribute essays by Paul Hills and Edmund de Waal and a longer interview.
