The Mysterious Stranger

by Mark Twain

*The Mysterious Stranger* is a novel attempted by the American author Mark Twain. He worked on it intermittently from 1897 through 1908. Twain wrote multiple versions of the story; each involves a supernatural character called "Satan" or "No. 44". All the versions remained unfinished (with the exception of the last one, No. 44, *the Mysterious Stranger).*
