It is always nice to have seasonal themes and in this episode Christmas is alive and well in the streets of very late 19th century London. And at 221 1/2 Baker Street, Holmes is investigating, rather coyly, why a value gem has appeared in the guts of a Christmas goose.
The gem has been stolen from a wealthy widow and it is believed that a local plumber is the bandit. He has already been arrested and placed in jail. But with the stolen gem turning up in such as odd place, Holmes will investigate this case leaving no goose uncooked.
The story is wonderfully written and takes us, as viewers, into many different places as we track the goose's previous path along with Holmes and Dr Watson. But it will be an advertisement that will close this mystery and set the holiday season back into motion. Another fine episode as we close out the first season. Good watch.
