last vow

In a corner of London, Watson received an anxious call from a friend, asking him to go to a gathering place for young people to take drugs to find his missing son.Without thinking much, Watson embarked on this unknown journey.However, he never expected that this simple search mission would lead him once again into the complex world of Sherlock.

When Watson stepped into that dark corner, the sight in front of him made him frown.And when he saw that familiar figure, Sherlock, addicted to the world of drugs, his heart sank to the bottom.For a case, Sherlock started taking drugs again, which he had given up long ago, which made his brother Mycroft very angry.But Sherlock insists that he did it to solve the case and that drugs can bring him inspiration.

Watson didn't say much, he just silently took Sherlock back to Baker Street.However, when he opened the door, he was surprised to find that Sherlock had a new girlfriend, and this girlfriend was Jie Lin, the bridesmaid at his wedding.Watson's heart was full of mixed feelings. He didn't know whether the relationship between Sherlock and Jie Lin was for the case, or whether it was true emotion.

In the days that followed, Sherlock and Watson investigated the case together.In order to get closer to his target, Sherlock even pretended to propose and sneaked into Magnuson's office.Watson follows closely behind, and together they explore the truth.However, just when Sherlock discovered that Magnussen was being threatened, the threatener turned around and turned out to be Watson's new wife Mary.Mary used to be a government agent. After getting tired of the life of licking blood with a knife, she chose to live in seclusion and marry Watson.But now, her identity was accidentally revealed by Sherlock. She originally wanted to kill Sherlock, but in the end she only wounded Sherlock out of compassion.

Sherlock used all his knowledge to protect himself and survived despite serious injuries.Watson learned Mary's identity from the sober Sherlock, but he chose to forgive Mary.However, things are not that simple.Mary's information was held by Magnussen and used to threaten the other party.In addition, Magnuson also possesses a lot of secret information, which is used to threaten various countries in the West, and even Mycroft has been threatened.

In order to protect the interests of Mary and the country, Sherlock and Watson found Magnuson again.But Magnussen was an excellent criminal with an excellent memory.Sherlock thought the other party had a secret warehouse to store threatening information, but eventually discovered that the information only existed in Magnuson's memory palace.In order to protect Mary's identity from being discovered, and to protect the interests of Mycroft and the country, Sherlock resolutely shot and killed Magnussen in front of the police, and he was convicted.

In order to protect his younger brother, Mycroft had no choice but to send Sherlock abroad, to Eastern Europe to work as an undercover agent for half a year.Watson and Mary sent Sherlock away, their hearts filled with reluctance and worry.However, just after Sherlock left, Moriarty's video was played on electronic screens across the country.It turns out that Moriarty was not killed in the original fall case, and everything was shrouded in mystery.

In order to expose the truth about Moriarty's survival, Sherlock was recalled to London again by Mycroft.He once again stepped into this city full of mysteries, ready to uncover the final truth.And Watson and Mary will also be by his side, accompanying him through this unknown journey.
