When it comes to discussing detective and thrilling series, there is nothing that beats Sherlock. The show has been around for years now and has managed to steal the attention of the viewers from the get-go. Unlike most of the other shows, this one is a British television series. The only downside to this show is the fact that it has four seasons till now and only 13 episodes in total.

For those who aren’t aware, Sherlock is a popular British detective series based on Sir Arthur Conan Doyal’s novels under the same name. The series is developed and created by Steven Moffat and Mark Gatiss and features Benedict Cumberbatch in the lead role. The show aired between 2010 and 2017 with three four-part seasons and one special episode.

The show is available and produced by BBC and is primarily shot across the UK, especially around areas of Cardiff, Wales, and North Gower Street. You also get a peek into the actual fictitious residence of Sherlock and Watson’s 221B Baker Street.

Sherlock has been well received by the audience across the years, especially due to the enthralling plot, amazing acting, and the overall setting of the show. 

What is the plot of Sherlock?

The plot of Sherlock isn’t very cohesive and a single story. It is broken down into detective Sherlock Holmes solving different cases that come his way. The show follows Sherlock, played by Benedict Cumberbatch, who is a consulting detective solving different case in London.

Not alone in the missions, Sherlock is assisted and helped by his friend and roommate, Watson on the cases that he works in. Watson returned from military services in Afghanistan where he worked with Royal Army Medical Corps. 

Despite how witty and intellectual Sherlock Holmes is, he is constantly being scrutinized by the Metropolitan Police Service Detective Inspector, Greg Lestrade. But, over time, he and his team realize how efficient and far-sighted Holmes is with the cases that he solves. 

With Watson discussing their adventure and their achievements via a blog, Holmes finds himself in the middle of a conversation dealing with the unnecessary media attention that he doesn’t particularly enjoy. 

Although the series takes you along a ride through different cases that are thrown at Holmes ways, the one consistent factors is Holmes trying to bypass his arch-nemesis, Jim Moriarty, with whom he crosses paths more than he’d like to admit or say.

Every single season takes you through the mystery and adventure of solving cases with Sherlock trying to bend rules and making the most out of the situation he finds himself stuck in.
