She is known for her novels about Burma, particularly A Marriage in Burmah, and for a controversy surrounding the authorship of For Love of the King, a play that she claimed had been written by the Irish playwright Oscar Wilde.
In 1893, she married Prince Chan-Toon, a Burmese barrister and nephew of a hereditary king of Arakan.
[5] In October 1921, Hutchinson's Magazine published an undiscovered play, For Love of the King, allegedly by Oscar Wilde.
The manuscript was offered to Methuen by Wodehouse Pearse along with a letter from Wilde (written in November 1894) stating that he was sending her the fairy play "for the love of the king" for her "own amusement".
During the trial, Wodehouse Pearse could not be found to testify (she was later discovered in prison serving a sentence for theft).
