Sherlock Goes Back To The Future Past

It's finally been confirmed - the Sherlock special will be set in Victorian London. After a disappointing series three (in my opinion) I had all but given up on the show, but it appears they know exactly how to drag me back into the fold. Now I'm like a child again, waiting for Santa to pay a visit (only this time, instead of presents I just want him to bring me the Christmas special).
Roll on Christmas (only 282 days to go).
