Can we get to know writers through the places they called home? Mark Twain built a Victorian in Hartford, Conn., that was idiosyncratic and distinctive -- flashier than the house of his neighbor Harriet Beecher Stowe, whose fame he was said to envy. Edgar Allen Poe, often struggling financially, moved a lot: He had to leave college because of a lack of funds, but his room there has been preserved. Agatha Christie had a country house perfect for one of her murder mysteries. Take a look at their homes and more.
