Cut and pasted from the BFI website:
"A Sherlock Holmes-inspired mouse battles the wits of a dastardly professor.
Basil of Baker Street is the mouse equivalent of our own Sherlock Holmes, and his position as the Great Mouse Detective is threatened by the dastardly deeds of the devious Professor Ratigan. What begins as a mystery surrounding the disappearance of a toymaker leads to a deadly threat against the crown itself."
It is showing on 23 July and on 28 July (this is when I am going!).
