The Strange Case of Dr. Jekyll and Mr. Hyde

Pop culture had long ago given me the gist of this story but reading the original classic was an entirely different experience. A very well-paced and well-written piece of horror fiction. I especially enjoyed that the viewpoint comes from a third-party - Doctor Jekyll's lawyer - who is sleuthing around trying to get to the bottom of this 'Mr. Hyde' business. What he discovers will haunt him for the rest of his life.
