Elizabeth’s purist attitude to the shop was at odds with her business partners’ commercial acumen and their desire to run the shop profitably. Tensions between Elizabeth and her partners were high and the shop was not a commercial success. Elizabeth’s disagreements with her business partners, the suicide of her sister Diana in March 1971, as well as the death of her mother in 1973, contributed to a number of serious health problems for Elizabeth. In 1973 she resigned from the company and the shop. She hoped her business partners would change the trading name of the shop but they refused and this caused Elizabeth considerable stress for the rest of her life. Despite her health problems and her excessive workload, Elizabeth was able to publish a new book, ‘English Bread and Yeast Cookery’, in 1977. In the same year Elizabeth was badly injured in a car accident and spent some time recovering in hospital. The book, however, received glowing praise from Jane Grigson in ‘The Times Literary Supplement’, where she suggested that every married couple should be given a copy. ‘The Observer’ remarked that the book was ‘a scathing indictment of the British bread industry’.
