Considered one of the most prolific female spies of the 20th century, as a triple agent for 
Communists in China, India, and the Soviet Union, Agnes Smedley was an American journalist and writer well known for her semi-autobiographical work, Daughter of Earth.
Agnes Smedley, author of Daughter of Earth, worked in and wrote about China from 1928 to 1941. These 18 pieces featured in Portraits of Chinese Women in Revolution —all out of print and most unavailable even in public libraries—are based on interviews with revolutionary women. They include descriptions of the massacre of feminists in the Canton commune, of the silk workers of Canton whose solidarity earns them the charge of lesbianism, and of Mother Tsai, a 60-year-old peasant who leads village women in smashing an opium den.
