Tolkien, Middle-earth, & Evil

How did evil enter into Middle-earth and does the original wickedness linger into the last year of the Third Age, the one-year period the action in The Lord of the Rings takes place? I take a look at those questions. However, the podcast's main focus is on Tolkien's masterpiece., therefore this is an overview. I have a blog with associated posts for each episode and or chapter. Some chapters will get extra TLC in the form of two episodes and a single post. Feel free to comment or ask questions on the blog.
