Charles Augustus Milverton: a name that fans of the canon would recognize immediately.

I don't remember if Sherlock's ambidexterity is also in the canon.

In the books, Milverton was a master blackmailer, and in their investigation, Holmes and Watson break into Milverton's house to steal the blackmail materials. Then they witness justice dispensed as one of the blackmail victims shoots Milverton dead, and also stomps on Milverton's face.

Eeeeeewwwwww.

All these facts were adapted into this episode's storyline, which makes this episode one of the few in this series with noticeable ties to the canon. You'd also think that this was a Rob Doherty-penned screenplay (it isn't), but it is nevertheless well-written.
