I stumbled upon two old Mark Twain books recently at a thrift store here in Florida and I bought them both despite the fact that one appeared to have writing in one of the front pages. I finally read the writing when I got home, it read: "The Mysterious Stranger is one of my favorites as it discloses the mystic element (in? sp) my father's nature. Sincerely Yours, Clara Clemens Gabrilowitsch. 3. October 1938." There is also a newspaper article attached to the front page written by Malcom W. Bingay with a question and answer about the book. Among other things, Bingay writes, "If any set of Mark Twain is advertised as "complete" and does not contain "The Mysterious Stranger," then the publisher ought to be prosecuted, put in solitary confinement for the rest of his life and have one toe nail pulled out every year just to keep him miserable." The book itself is not in excellent condition.
