The final problem

The Holmes team (meaning Sherlock, Mycroft and John) decides to confront Eurus -the little sister, once for all. The youngest Holmes is supposed to be safely jailed on a secret fortress island. But it soon appears that Eurus is a master of manipulation, and that she has planned this meeting long ago...

The lying detective

John blames Sherlock for Mary's death and refuses to see him. Lost without his friend, Sherlock becomes paranoid and declares that Culverton Smith, a powerful magnate, is a serial killer. Why ? Because he met his daughter, who claims the Smith Company created a drug that can erase a short period of memories, and that her father confessed his crimes before having her taking this drug. Are Sherlock and the young woman both storytellers ?

The 6 Thatchers

Mr Welsborough is having a party for his 50th birthday. He is happy to receive a phone call from his son, travelling in Tibet. But the call is interrupted. One week later, after a car crash, the body of his son is found right in front of the house.

Sent by the police, Sherlock solves the mystery right away. He is more intrigued by the disappearance, in the house, of a bust of Margaret Thatcher. In this strange theft, he sees a hint of what is really obsessing him: Moriarty's inheritance.

But the trail may lead to a troubling discovery about Mary's past.

Christmas episode 2015 - the abominable bride

1895. Dr Watson comes back to London, wounded after the Afghanistan war. Thanks to an old acquaintance, Stamford, he meets a flatmate, Sherlock Holmes. Some times later, after a few novels, a certain notoriety, a marriage and the first domestics with Mrs Watson, comes an odd case :

Emelia Ricoletti kills herself very publicly for her anniversary of marriage. Trouble is, she kills her husband no less publicly a few hours later. 

Dialogues: Johnlock domestics

Holmes the cold rational intellectual versus Watson the passionate fighter. Head & fists, logic & emotion, reasoning & acting.
Friendship stories can be as beautiful and powerful as love stories. Friendship may be a kind of love, in a way.   

That is really a major trump card of the serie: domestics -as Mrs Hudson calls it- between Sherlock and John, the Johnlock couple. As in every couple, it can go from simple teasing to harsh words and long-lasting quarrel. 
These scene are present in each episode, I chose just some of them.

Dialogues: Sherlock's character

Is Sherlock really an autist or does he choose to stay away from "normal people"?
He is often absent-minded, slightly depressed -bored.
In the serie, that gives an opportunity for funny dialogues:

Jeff the cabbie

I have a special tenderness for Jeff the cabbie, the first villain in the show. And a damn good one!

Jeff is a taxi driver (probable tribute to masters of their art, Scorcese & De Niro). He is a guy you would hardly notice. Just the back of an head, as he says. Point is, he notices how people think and act. And if, by ill luck, he notices you, that's not good...

Philip Anderson, the penitent

Sherlock and Philip Anderson have a special relationship, from the beginning. Sherlock usually ignores people, but he dislikes, despises Anderson. His presence makes him nervous. 

3.3 His last vow

In his best man's speech, Sherlock made a last vow: protect John & Mary. Charles Augustus Magnussen, a media mogul and a powerful man, understands very well the interest of this lever on Mycroft's brother.

Magnussen decides to blackmail an MP, and then provokes Sherlock. He chooses to provoke also Mary, who will show her true face.

But first, he will have to face another adversary : John...

2.2 The Hounds of Baskerville

But there is a high-security military base nearby, performing genetic experiments, which could have a responsibility in this mystery.

1.2 - The blind banker

Sherlock is called by an old acquaintance. An intruder came in a high secured bank and painted a mysterious sign on a painting. The bank wants to know how he did it. 
Soon after, the trader working in the office where the intrusion occured, commits "suicide". Or so it seems... He was coming back from a trip in China.

1.3 - The great game

Mycroft ask for his brother's help (sort of) in dealing with an affair of national interest.
While Sherlock affects to refuse, a bomb explodes in Baker street. That's the beginning of a game which will lead to a crucial meeting between Sherlock and his biggest fan...
