She was a prolific writer of short stories, published as anthologies, and novels, often with a romantic or supernatural theme. She wrote over 30 books on spiritual subjects, such as The Cosmic Christ (1930), and her own personal psychic experiences were documented in Ghosts I Have Seen (1920). Apart from her literary output, she was a gifted amateur artist, embroiderer, and an accomplished pianist; she was also a skilled orator who spoke up for workers' rights.
Life and work
In her teens she assisted her father in his work, and in 1889 moved to London where she had her first novel, And They Two, published, and became involved in humanitarian "rescue work" in the East End. In 1891, she married Clarens Tweedale. In London, she moved in the best social circles, counting among her friends, poet Robert Browning, artist Frederic Leighton, Anne Proctor (mother of Adelaide Proctor) and many others. She also had influential contacts abroad including Marie, Countess of Caithness, Duchess of Medina Pomar (Papal States), who was close to prominent theosophist, Helena Blavatsky. In 1901-1902, her recently published work, Her Grace's Secret was reworked into a play by Arnold Bennett, but it was never produced.  
Claiming to be psychic from a young age, she became involved in spiritualism and theosophy, and was a close associate of Helena Blavatsky. She worked with the mediums Charles Williams and Cecil Husk (1847–1920), and was called as an expert witness when trance medium, Meurig Morris, sued the Daily Mail for libel in April 1932—although the case went against Morris, no fraud or dishonesty on the medium's part was proven.
