There are three cartoons I'd always watch as a kid for Halloween: "It's the Great Pumpkin, Charlie Brown," "Halloween is Grinch Night," and "The Legend of Sleep Hallow (1949 version)." As much as a cartoon can be, it follows the plotline of the story by Washington Irving. The Headless Horseman was a mysterious and spine-chilling character/creature. I would've never guessed his origin story though if I never read this book. The fact that he's also called the "Galloping Hessian" was a detail that made the character seem less otherworldly and more tangible. While I did find this story dramatic and filled with outdated language, I would recommend reading it during fall, especially in October during Halloween. That would make the experience truly spooky and hair-raising.
