The Adventure of the Blue Carbuncle
The Adventure of the Blue Carbuncle is a short story that is part of the Sherlock Holmes series by Aurthur Conan Doyle. It was first published in January, 1892.
I didn't find this story to be very interesting, perhaps it's just the time gap. And, while I like the idea of a crime-fighting genius like Holmes, I found a lot of his abductions to be rather far-fetched.
