N.44., lo straniero misterioso

Blurb

The Mysterious Stranger is the final novel attempted by the American author Mark Twain. He worked on it periodically from 1897 through 1908. The body of work is a serious social commentary by Twain addressing his ideas of the Moral Sense and the "damned human race".
Twain wrote multiple versions of the story; each is unfinished and involves a supernatural character called "Satan" or "No. 44".
