Before her death in 2002, Mary Wesley told her biographer Patrick Marnham: 'after I met Eric I never looked at anyone else again. We lived our ups and downs but life was never boring'. Eric Siepmann was her second husband and their correspondence charted their life together (and apart) with unusual candour and spirit.

These remarkable letters, which were inspired by Mary's great love story with Eric, were also the means by which the novelist found her voice. Entrusted to Marnham in two size -5 shoe boxes, this is one of the great surviving post-war correspondences.
