This special illustrated and annotated edition of August Derleth's complete Mythos stories (aside from the Lovecraft collaborations) makes available for the first time all of the author's solo writings on the subject. It includes as well the three 1931 Mythos tales ("Lair of the Star Spawn", "Spawn of the Maelstrom", and "The Horror from the Depths") which Derleth wrote jointly with his Sauk City boyhood friend Mark Schorer. Along with "The House in the Oaks" left unfinished by Robert E. Howard, completed and published by Derleth in 1971, the year of his own death.
