Hatto was supposedly a virtuoso pianist, whose talent was discovered only very late in her life, when she was already in her seventies. She was notable for being able to masterfully play a wide variety of works, including compositions by Beethoven, Mozart, Chopin, Liszt, and Rachmaninoff. But it turned out that her husband had been taking recordings of other pianists and claiming they were recordings of Joyce. Singer tries to understand what motivated Hatto's husband to do this. It's a good article. Definitely worth a read.
