The biggest mystery of all, however, concerns Hammett Unwritten itself.   In Gordon McAlpine’s afterword, he admits to the 2012 discovery of the manuscript and the falcon in the Lillian Hellman collection at the University of Texas, Austin.  Subsequently, he recognizes the author’s name, Owen Fitzstephan, as a character in Hammett’s novel, The Dain Curse.  Fitzstephan not only resembles Hammett physically but is that novel’s own evil mastermind.
