Basil of Baker Street

Basil is a detective based on the fictional sleuth Sherlock Holmes and the primary protagonist of The Adventures of Basil the Great Mouse Detective. His main goal is to get Professor Ratigan behind bars and rescue Olivia Flaversham's father, while simultaneously preventing a royal assassination. There are a few differences between Basil in the book series and in the film version, such as mercurial moods in the latter. He also plays the violin rather well in the movie, whereas the book series stated Basil's violin playing was atrocious— instead, Basil played the flute.
