‘There is a variable delicate friction between the interests of wives, husbands and children, and between human beings and nature,’ Penelope Fitzgerald wrote in a piece about her friend Stevie Smith, published in the LRB in 1981. ‘One might say between the seaside and the sea.’ She would know. The years of Fitzgerald’s life that she drew on for The Bookshop (1978) and Offshore (1979) combined complicated family dynamics with precarious physical circumstances, waving/drowning halfway between the shoreline and the water.
