Basil and the Lost Colony (The Great Mouse Detective, Bk. 5)

An arrow with strange markings is the clue that sends Basil of Baker Street, the Sherlock Holmes of the mouse world, scurrying off to Switzerland in search of the Lost Colony. There is the meeting with Inspector Cherbou of the Paris policemice; there is the rescue of the Faversham sisters; and then Basil leads thirty-two mice on an expedition up a towering mountain.

And what of the mysterious shaggy mouse, the lovely mouse soprano Relda, or Professor Ratigan, sinister ruler of the mouse underworld?

The Case of the Lost Colony is clearly the most extraordinary exploit of this extraordinary detective!
