was Marmite. After India Wills was back again at the Royal Free Hospital in London from 1938 until her retirement in 1947. During the Second World War she was a full-time pathologist in the Emergency Medical Service. Work in the pathology department was disrupted for a few days in July 1944 (and a number of people were killed) when the hospital suffered a direct hit from a V1 flying bomb. By the end of the war, she was in charge of pathology at the Royal Free Hospital and had established the first haematology department there.

There were a further two papers in the 1920s before she started her work in India. Four reports of her field and laboratory studies in India were published in the Indian Journal of Medical Research in 1930 and 1931. After her return to England, there were a number
