As a "humor" book, it's a well-written and timeless one. you can still feel close to characters nearly 130 years after it's been published.
And if that's not enough for you, there's an Audiobook version read by Hugh Laurie. He's done an absolutely brilliant job portraying the characters and he deserves to be praised for it. I enjoyed every minute of listening to this audiobook and strongly recommend it to anyone have an interest in this genre.
