His Last Vow

Plot

John Watson, whose wife Mary is now visibly pregnant, finds a disheveled Sherlock Holmes in a crack house under the influence of drugs. John attempts to force him to rehabilitate, but Sherlock insists that he was undercover for a case. Mycroft confronts Sherlock about the drug use and realises that Sherlock is investigating Charles Augustus Magnussen, a newspaper owner who blackmails people. Sherlock has been enlisted by Lady Elizabeth Smallwood to negotiate the return of stolen letters written by Smallwood's husband. Mycroft warns Sherlock not to go after Magnussen, which Sherlock dismisses.

John is also shocked to discover that Sherlock is in a relationship with Mary's bridesmaid, Janine. Sherlock tells John that he is dating her because she is Magnussen's personal assistant, and he uses their relationship to assist him with breaking into Magnussen's office in London. Inside, Sherlock and John find an incapacitated Janine, and Sherlock happens upon Mary holding Magnussen at gunpoint. Mary shoots Sherlock, who harnesses all his mental powers to stay conscious. He is taken to hospital. In his mind palace, Sherlock fades away, at the same time in the real world Sherlock dies on the operating table in pre-op preparation. In the mind palace, Moriarty convinces Sherlock that he's letting John down by dying, which convinces the mind palace Sherlock to get up and escape. At this time, in the real world, Sherlock's heart begins to beat again. The surgeons attempt to help revive him, by giving him oxygen. Sherlock wakes up in surgery and mouths "Mary". Mary comes into the hospital and is met by John, who says that Sherlock had survived surgery. Mary visits the exhausted and in critical condition Sherlock and warns him not to denounce her. John nonetheless begins to suspect something after he finds that Sherlock replaced John's chair in the Baker Street flat and left a bottle of Mary's perfume on the table next to it.

Sherlock slips out from the hospital and arranges a meeting with Mary. Using a ruse, Sherlock exposes Mary's secret life as an assassin to John, and all three return to Baker Street to sort it out. She tells them about her past, and that Magnussen has information on her that would put her in jail for the rest of her life. Sherlock deduces that she intentionally shot him in a non-lethal spot and called an ambulance. Sherlock tells John that he observes John's addiction to danger and that John was most probably attracted to Mary because of her hidden past. Mary gives John a memory stick containing information on her, marked with her true initials A. G. R. A., telling him the contents will destroy his love for her. After not viewing the memory stick for a few months, John decides to destroy it without reading it and to love Mary regardless. The couple spend Christmas with the Holmes brothers at their parents' home, where Sherlock takes the opportunity to drug everyone but John so that they can steal Mycroft's laptop. Sherlock takes a confused John to meet Magnussen at his estate, Appledore, which he believes contains Magnussen's blackmail archive. During their confrontation, Magnussen explains his purpose in putting pressure on Mary was to arrive at Mycroft via John and Sherlock. He also reveals that he was behind the kidnapping of John, as seen in "The Empty Hearse".

Sherlock offers to trade Magnussen's information on Mary for the state secrets contained in Mycroft's laptop. However, Magnussen is aware that Sherlock is setting him up in a trap. Magnussen then explains Sherlock's plan to John: security services looking for the laptop using a GPS tracker it contains will raid Appledore and, upon finding the laptop, will have a legal reason to search the blackmail vaults. Magnussen, with considerable glee, reveals that the plan will not work because Appledore's vaults don't physically exist, but are stored in his Mind Palace. By giving Magnussen the laptop, Sherlock and John are now guilty of attempting to sell government secrets and can be imprisoned for high treason, whereas Magnussen remains legally untouchable. When Mycroft and the police arrive, Sherlock shoots Magnussen in the head, having realised that this is the only way to free his friends and everyone else from his power.

Mycroft convinces the government to spare Sherlock a trial and, as an alternative punishment, press him into a highly dangerous mission in Eastern Europe. He is, however, recalled within minutes when TV screens all over Great Britain are hacked to broadcast a loop of a static image of Jim Moriarty asking "Did you miss me?" A post-credits scene shows a very much alive Moriarty asking if the audience missed him as well.

Casting

In July 2013, it was announced that Danish actor Lars Mikkelsen would star as the main villain of the third series of Sherlock. Mikkelsen first appeared in a non-speaking cameo appearance at the end of "The Empty Hearse". The portrayal of Magnussen was described by Steven Moffat as "terrifying". Mikkelsen was suggested for the role by producer Sue Vertue and recorded an audition video for the production team in which he urinated in his barn. Mikkelsen was starring in a film set in East London at the time and had picked up a London accent, so he had to "re-Dane-ify" his accent.

Moffat and Vertue's son, Louis Moffat, played a young Sherlock in two scenes and Benedict Cumberbatch's real-life parents, Timothy Carlton and Wanda Ventham, reprised their roles as Sherlock's parents from "The Empty Hearse". Steven Moffat has commented that Sherlock "runs on nepotism".

Writing

Steven Moffat confirmed that the cliffhanger, the return of Moriarty, had been planned as far back as series two, when he discussed the plan for Moriarty's character with actor Andrew Scott. However, he joked that he was as surprised as the viewers to see Moriarty return, noting that it is impossible to fake shooting oneself in the head. Scott appeared in a short post-credits scene talking to the camera, both firsts for the show. Moffat has commented that viewers will have to wait "years" to see the resolution of the cliffhanger.

Gatiss and Moffat had considered adapting the character of Charles Augustus Milverton for some time, considering him to be a "brilliantly realised" villain. Moffat viewed Magnussen as Sherlock's "intellectual mirror" and a "unique baddy", and stated that he fell in love with him. The character of Magnussen was originally conceived as an American retaining the name of Milverton, but Moffat changed both his nationality and name when Mikkelsen was cast. He found the name Magnussen on a website of Danish names, looking for one that resembled Milverton, the name of the original character from Doyle's short story. Gatiss noted that the character is a "fascinating new place to go" due to his differences from Moriarty. When Mikkelsen received the script, he stated that his first impression was that it was "the best script I've ever read". Contrasting Magnussen to Moriarty, Cumberbatch stated that he was "so chilling because of how real he is, how normal he is", and that he is "not driven by a mad, chaotic joker's energy that Moriarty has".

On the introduction of young Sherlock, Moffat noted that it was the logical course to take after the introduction of the Holmes parents: "Once you've got the parents in and you've got the sibling rivalry and stuff, people start to think, 'well what was young Sherlock like?' You just want those things, you want to see those things, it's part of updating it."

Filming

Director Nick Hurran had previously worked with Steven Moffat on several episodes of Doctor Who, including the fiftieth anniversary special.

Filming for "His Last Vow" began on 29 July 2013. Some filming was in Cardiff, and part in Leinster Gardens, where houses 23 and 24 were shown to be mere façades. Scenes set at 'Appledore', Magnussen's house, were filmed at Swinhay House in Gloucestershire, owned by Sir David McMurtry, boss of Renishaw engineering.

The post-credits scene—depicting Moriarty (Andrew Scott) saying "Miss me?" to the camera—was originally longer, but was cut at Gatiss's recommendation to tease the audience.

Broadcast and reception

The last Sherlock episode of series 3, "His Last Vow" was first broadcast on BBC One on Sunday 12 January 2014 between 8:30pm and 10:00pm GMT. Overnight, the episode was watched by 8.77 million viewers, a 31.9% share, which was down from 9.2 million (33.8%) for the opening episode of the series, "The Empty Hearse". However, when final ratings were factored, it increased to 11.38 million, the same as "The Sign of Three", but still down from "The Empty Hearse". The episode was later repeated on the digital channel BBC Three on Friday, 17 January 2014 from 9pm GMT.

The British Board of Film Classification gave the episode a 12 certificate, for "moderate violence, drug references and one use of strong language". The episode was released in the UK on DVD and Blu-ray Disc with the other episodes in the series ("The Empty Hearse" and "The Sign of Three") on 20 January 2014.

Critical reception

"His Last Vow" received critical acclaim, with Louisa Mellor of Den of Geek saying that the episode was "as good a finale as Sherlock's ever had", with a very strong plot. Mark Jefferies of The Mirror called the episode "easily the best yet in this run", with a "fascinating" plot. He also praised Mikkelsen as "brilliant". Josh Wilding, also writing for The Mirror, said the episode "was in many ways the best episode of Sherlock yet" and called it "simply one of the greatest TV shows of all-time", giving it 5/5. Caroline Frost of the Huffington Post called it a "fitting finale to the series, with writers and actors all saving their best for last", despite the third series' "patchy" performances. Serana Davies of The Telegraph called the episode "the best of the lot" and gave 4 out of 5 stars, calling Moffat "the superior Sherlock writer". Although her review was mainly positive, she questioned whether the programme had become "a little vain, rather a show-off". Lucy Mangan of The Guardian said the episode was "perfect", and a "ceaseless flow of wit, invention and intelligence", a sentiment echoed by Ellen Jones of The Independent, who stated that it contained "intelligence, humour and obscure fanboy references galore" which "delivered the goods". She went on to state that it is "enough detail in this episode to justifying watching it again and again, once weekly, until series four". Chris Harvey of The Telegraph praised the "beautifully done" conclusion of the episode featuring Moriarty, saying it was "very playful, very neat. And very unexpected". Sandipan Deb, writing in Indian newspaper Mint, was positive about the episode, calling it "the best" episode in the series, and praised its "stunning twists and turns, its thrilling upending of what we have known about the characters for a lifetime, an emotional depth not seen before, and its clever throwaway references to the Canon". Deb also praised the "uber-cool cinematic technique", singling out the moment when Sherlock has been shot and falls to the floor as an "extraordinary leap of the imagination and cinematic bravura". However, it was stated that the writers were "influenced by the zoned-out Holmes films directed by Guy Ritchie".

However, Neela Debnath, also of The Independent, said that the episode was "trying far too hard and is coming across a tad foolish", and consequently "failed to hit new heights". Despite this, she did praise Mikkelsen as Magnussen, calling his performance "sterling". Jeff Jensen of Entertainment Weekly took issue with Sherlock killing Magnussen at the end, instead of outsmarting him, viewing it as out of character: "He [Sherlock] had the smarts to brainstorm more inspired solutions to the problem of Magnusson [sic], and the seasoning to resist a degrading one". An article in the Daily Mail penned by Tom Kelly, claimed that the episode was symptomatic of the BBC's "left-wing bias", arguing the episode's villain, Charles Augustus Magnussen, was portrayed as a capitalist, foreign-born newspaper baron, with similarities to Rupert Murdoch. Media commentator Roy Greenslade contextualised the criticism by suggesting the BBC, rather than Sherlock, is the Daily Mail's "real enemy". The episode angered fans as it had removed the woman who, in Doyle's story, had shot Milverton. After the airing of "His Last Vow", Moffat and Gatiss said in an interview with Empire Cinemas:

Moffat: Also, if you read [The Adventure Of] Charles Augustus Milverton, Dr. Watson in the opening paragraph tells you that he's about to tell you a porkie. He says, 'I even now must be very reticent.' I think what Doyle is hinting at is that Sherlock Holmes and Dr. Watson sat in Baker Street and said, 'Right, we're going to have to go and kill him, aren't we? That's the only way we can do this.' So they break in, kill him, and then Dr. Watson writes up a version of the story that puts the murder [on someone else].

Gatiss: They're hiding in their burglar masks behind the curtain, and this random woman comes and shoots Milverton in the face and then grinds her heel into his face. It's odd, isn't it? So I mean really, it's just an extrapolation of saying, 'Well, he probably did it, I think.'

Moffat: If Sherlock Holmes decided that somebody should die, he would kill them. I don't think he'd have any problem with that.

Gavia Baker-Whitelaw, writing in The Daily Dot, said that the removal of a female character was "An unfortunate occurrence that neatly fits in with Moffat's track record with female characters in both Doctor Who and Sherlock", Baker-Whitelaw goes on to question whether Mary could have killed Mikkelsen, instead of "playing right into the hands of fans who believe Moffat is a misogynist who writes all of his female characters into the same corner", and questions whether Moffat is indeed a misogynist.

Steven Moffat's writing, said Emma Dibdin of Digital Spy, is "a few degrees colder than his colleagues'", which helped the episode go back to the "cerebral, mystery-driven tone some viewers have been left craving". Paul Jones, of the Radio Times, praised Moffat's "grand, filmic episode", whilst Daniel Krupa, writing for IGN, said the episode was a reminder of "just how brilliant Sherlock [...] can be".
