The Case of Charles Dexter Ward
The "Necronomicon" is mentioned in a number of Lovecraft's short stories and in his novellas "At the Mountains of Madness" and "The Case of Charles Dexter Ward". However, despite frequent references to the book, Lovecraft was very sparing of details about its appearance and contents. He once wrote that "if anyone were to try to write the "Necronomicon", it would disappoint all those who have shuddered at cryptic references to it."
