In 1900, von Puttkamer published her first book of poetry under the pen-name Marie-Madeleine, titled Auf Kypros, which was a collection of lesbian-themed erotic verses. Auf Kypros became a best-seller throughout the German Empire, particularly in high society circles. At the time, her work was seen as contrary to societal standards on morality and was even considered pornographic. Throughout the next fourteen years, von Puttkamer published 28 more books, including poetry, short stories, plays and novels. By 1910, her writings were not only centered on lesbian erotic love but also on the use of morphine. By the end of her life, von Puttkamer had written over 46 works.
