From the Master of Cosmic Horror ... Supernatural Horror in Literature, H.P. Lovecraft's "master's thesis," is a tour de force of literary analysis, tracing the origins of the horror genre back to its inception and beyond. In it, Lovecraft follows the development of horror-lit down through the centuries--from Horace Walpole, through Mary Wollstonecraft and Bram Stoker, to Algernon Blackwood and Arthur Machen, and on into his own time.
