Sherlock Holmes. These days he's really popular. And how can you not enjoy the versions out there
when you have this: 
or this: 
But as I my friend told me, if you're going to read anything Sherlock Holmes, you better read The Hound of the Baskervilles.
What surprised me was how entertained I was by reading it. I had no idea that Sir Arthur Conan Doyle (because, yes, you must say his whole name to get that hint of British authority) was so clever with words. This mysterious tale is really well-known and I knew what was going to happen going in, but I didn't realize that I would have such a great literary treat to sink my teeth in to. Told in the perspective of Watson, we get to see reports, journal entries, and firsthand experience. Holmes is eccentric, smart, and just as socially awkward as he is now often seen on screen.
And really, who doesn't like a good old-fashioned ghost story about a hound? You gotta read this book!
