I'm reading Wallace Stegner's Angle of Repose in the mornings (when D reads Huck) and have come across references to Huckleberry Finn in that. Stegner's book is based directly on the letters of Mary Hallock Foote, fictionalised as Susan Burling Ward. Susan contributed to the Century magazine in the same issue of February 1885 which contained the final installment of The Aventures of Huckleberry Finn. This morning whilst D was reading about Huck reaching the Ohio River I was reading about Susan meeting and talking to Samuel Clemens (Mark Twain), who was the principal speaker in honour of General Ulysses Grant at a banquet in Chicago.
I think I read about the Stegner book on a blog, but didn't note which blog. So, thank you to whoever it was - I am enjoying this book.
