But they are not alone: soon the ghost of Sherlock Holmes is following the gang around, and it seems he is trying to help them, but is he?

Cultural references

  • This episode is a homage to the Sherlock Holmes stories written by Sir Arthur Conan Doyle in the late 19th Century.
    • Baker Street is a real street in London; Sherlock resided there in the novels.
    • A carbuncle is an old word for "gemstone"; the Blue Carbuncle is reference to The Adventure of The Blue Carbuncle, one of Doyle's short stories that featured Sherlock Holmes. While the mystery wasn't really "unsolved", Holmes refused to turn the culprit into the police which means it would have been officially recorded as such.
    • The Great Detectives Club is most likely a reference to the Diogenes Club. The Diogenes Club was a club ran by Holmes's brother Mycroft, in which members were forbidden from speaking.
