Loveliest of Friends by G. Sheila Donisthorpe

From the back cover: 'The World Condemned Their Love. When this book first appeared in England, it created a sensation and was favorably compared to The Well of Loneliness. It is the powerful and bitter story of Audrey and Kim and the perverse yet compelling attraction that drew them together. The strange theme of this novel has seldom before been treated with such delicacy and deep understanding.'
