A. Merritt is the best author ever, for a very good reason. He LIVED his storys. There is evidence that he actually believed he was in the worlds he wrote (you may say insane, but i won't because insanity is relative). that is why there is so much more detail than any other story. i happen to own 4 of his books, this and The Face In The Abyss, as well as 2 others.
