The Adventure of the Empty House
Each episode is inspired by one of the literary works of Sir Arthur Conan Doyle. Many of these are direct rewrites of the original stories, such as "The Adventure of the Empty House", "The Adventure of the Speckled Band", "The Five Orange Pips", "The Red-Headed League", and "The Adventure of the Engineer's Thumb" - while others are drastically different from the stories on which they are based.
