Sherlock Holmes & The Secret Weapon (Dramatised) (Unabridged) - Arthur Conan Doyle
This "book" is just the audio part of the movie, Sherlock Holmes and the Secret Weapon. Half the time, I didn't know what was going on, because there isn't narration or anything like that. If you weren't familiar with the storyline at all (like I basically was), you would be almost completely lost. It's just the movie without anything to watch.
