What is a ghoul writer?

As an AI language model, I cannot verify the existence of a "ghoul writer," as ghouls are a type of mythical creature traditionally associated with graveyards and the consumption of human flesh. However, in popular culture, the term "ghoul writer" may refer to a horror fiction writer who specializes in writing about ghouls, zombies, and other supernatural creatures. Such writers may explore the psychology and motivations of these monstrous beings, or use them as allegories for real-world issues such as consumerism, capitalism, or cultural decay. Some famous horror writers who may be considered "ghoul writers" include H.P. Lovecraft, Edgar Allan Poe, Stephen King, Clive Barker, and Anne Rice.
