As Sherlock heads into its third and final instalment this weekend, fans are left with the worrying possibility that “His Final Vow” may see the Holmes brothers facing off against each other.

The final episode of the season is set to see a case of stolen letters leading Holmes (Benedict Cumberbatch) into “a long conflict with Charles Augustus Magnussen (Lars Mikkelsen), the Napoleon of blackmail, and the one man he truly hates.”

We’ve already caught a glimpse of Magnussen, the man we suspect of almost killing Watson (Martin Freeman), in “The Empty Hearse” and based on the details of the new promo trailer for Sunday’s episode we know he’s a man who turns Sherlock’s stomach.

The BBC’s final press release for the episode earlier this year posed the question “How do you tackle a foe who knows the personal weakness of every person of importance in the Western world?”

We’re guessing that Magnussen may have the goods on Mycroft. Why else would he warn Sherlock “If you go against Magnussen then you’ll find yourself going against me.” Might Mycroft simply have no choice in the matter?

The rather fluffy “The Sign of Three” witnessed Sherlock’s declaration that he would protect and defend John and Mary Watson with everything he has. We get the feeling the real fight has just begun.

Benedict Cumberbatch returns for the last episode of the season as Sherlock Holmes, with Martin Freeman as John Watson, Mark Gatiss as Mycroft, Rupert Graves as Inspector Lestrade, Una Stubbs as Mrs Hudson, Amanda Abbington as Mary Watson, Louise Brealey as Molly Hooper and Lars Mikkelsen as Charles Augustus Magnussen.

Catch it on BBC1, Sunday January 12 at 9 pm.
