Dear Sirs;

As an older (much) reader of Twain's writings, I find much food-for-thought
in his works and must say that his (???) Mysterious Stranger is one of my
favorite head-ache works.

Why should I be cautious about it? Why should I be sceptical about its
authorship? Its origin and form? Its intent and literary ranking?

Why---why---why?

Please advise.

Thank you,

Tom Smith.
