Holmes and Watson face their greatest challenge yet in the series finale…

Last week we met Sherlock’s dastardly sister, Eurus, and the episode’s shocking climax left us with a lot of questions.

Why has she been dressing up as so many meddlesome characters? What does she want from her brother? Has she really just shot John Watson?

With no preview available for this finale, we’re on tenterhooks. Here’s hoping there’s a huge showdown between the three Holmes siblings – and it goes without saying that we’re rooting for John.

They wouldn’t kill him off… would they? Let’s hope this is a belting end to a top-notch series!
