Howard Phillips Lovecraft (1890-1937), the famous American writer, is revealed as a particularly interesting and avid letter writer. In this "work" of his, not as well-known as his short stories and novellas, the reader can discern his unique personality and extensive knowledge. The recipients of his letters are his relatives or figures from the world of literature and art such as Clark Ashton Smith, Howard, Derleth, etc. His knowledge of ancient Greek mythology and language is particularly impressive, the influence of which is evident in his writings. His letters may constitute the most complete biography that could have been written for such an important, controversial, and dark figure as H. P. Lovecraft, who was destined with his work to be counted among the distinguished horror writers.
