CASE 03 / BAKER STREET MYSTERIES
The Blue
Carbuncle.
A jewel worth a fortune. A hat not worth a shilling.
And a goose that brought their worlds together.
Winter in London. A missing stone. An innocent man in custody.
Holmes and Watson follow the trail of a most extraordinary Christmas dinner.
Based on “The Adventure of the Blue Carbuncle” by Arthur Conan Doyle. Original dialogue, illustrations, and documents; the solution follows the original. No knowledge of the story is needed. If you already know the ending, become an assistant to new detectives.
About the adaptation and source
We have retained the central plot and characters. Some information from the final confession appears in earlier files so that players can reconstruct the scheme themselves. The solution and Holmes’s decision remain unchanged. The dialogue is original, not quotations from a modern translation. The English original at Project Gutenberg contains the solution.
