Everyone knows that the Mystery of the Missing Twins could never have been solved by an ordinary detective. But Basil, of course, was far from ordinary. Famous in the world of mice as Sherlock Holmes is in the world of people, Basil listened often and long at the feet of the great Mr. Holmes.

It's a rattling good mystery with a harrowing trip to Mousecliffe-on-the-Sea, a strange meal at the Grey-mouse Inne, a secretive boarding of the yacht Victoria, and an exciting encounter with the Terrible Three.
