Basil of Baker Street

SHERLOCK HOLMES OF THE MOUSE WORLD!
Basil—famous sleuth of mousedom—lived in the cellar of Sherlock Holmes' house. A devoted admirer of the great detective, he had learned his craft by listening at the feet of Holmes himself.

The Mystery of the Missing Twins was one of the strangest cases in Basil's career. He had only a few crumbs of clues with which to find solutions to such baffling questions as: Who had masterminded the plot? Where were the twins, Angela and Agatha, being kept?

Then came the sinister kidnappers' note signed by the Terrible Three. Basil knew he had not a moment to waste—the twins must be found at all costs!
