I've given two papers on the subject, one at Elmira and the other at ASA. The strongest arguments are contained in the letters from Susy to Louise Brownell. Some of the letters are to be found in Charles Neider's Introduction to "Papa," and photocopies of Susy's letters to Louise are in the Mark Twain Papers. The originals are in the library of Hamilton College. There is no question but that it was a passionate relationship, a love relationship--but I am cautious about the language I use to describe it. Does it explain Susy's sudden removal from Bryn Mawr? My guess is yes--the school year was not complete and there was no other reason that I am aware of that would have required Susy to withdraw before the year was over. From mutual friends we also know that Louise had asked Susy to live with her the following year at Bryn Mawr. There's more to be said on this subject, which I intend to do one day soon....
