The Adventures Of Sherlock Holmes. The Blue Carbuncle.

The Adventures of Sherlock Holmes is the name given to the TV series of Sherlock Holmes adaptations produced by British television company Granada Television between 1984 and 1994, although only the first two series bore that title on screen. The series was broadcast on the ITV network in the UK, and starred Jeremy Brett as the famous detective.

The Blue Carbuncle.
A plumber, John Horner, is arrested just before Christmas and charged with stealing a famous jewel, the Blue Carbuncle, from Lady Morcar. He denies the theft - but he has a criminal record, and all the evidence is against him.

After Holmes's doorman finds the Carbuncle in a Christmas goose, Holmes uses an old hat to track the goose to a poultry dealer, then traps the servant who stole the jewel and framed the plumber.

The Blue Carbuncle has a dark history, and the stone features in the programme's opening credits with turbulent scenes from its past.
