She holds a Bachelor's in International Media and Entertainment Management, as well as an MA and Ph.D. in Creative Writing. There is little she loves more than discussing her favorite TV shows with fellow fans. One day, she hopes to publish an original fantasy novel.

The perfect British detective crossover officially arrives this holiday season. The Brits have been producing incredible detective and crime dramas for decades, adapting books and characters from renowned genre authors like Agatha Christie, Arthur Conan Doyle, Colin Dexter, Ann Cleeves, Caroline Graham, and many more, while also creating plenty of exciting, gripping original murder mysteries like Silent Witness, Death in Paradise, and Luther.

Recently, the BBC and BritBox have co-produced one of the best and most acclaimed original new detective dramas. British comic legend David Mitchell stars as master puzzle setter and amateur investigator John "Ludwig" Taylor in Ludwig, as he and his sister-in-law Lucy (Anna Maxwell Martin) devise a scheme for John to take his missing twin brother James' place as a detective in the Cambridgeshire police. The show's pilot was the biggest BBC comedy launch since 2018, while the full first season was one of the best-performing scripted series of the 2020s, attracting nearly 10 million viewers in a month.

Season 2 recently premiered on BBC One and BBC iPlayer in the UK and will arrive on BritBox in the US and Canada on October 13. Mark Brotherhood's show has also already been renewed for a third, six-episode season, and filming is currently underway. The good news doesn't stop there, however. On Wednesday, September 2, the BBC and BritBox announced that Ludwig will also return for its first-ever Christmas special later this year, featuring one of the most beloved TV detectives of all time.

Sir David Suchet, who portrayed Agatha Christie's iconic Belgian sleuth Hercule Poirot on ITV's Poirot for over 20 years, will attend Ludwig's festivities. Rather than helping John solve the case, however, Suchet joins the story as a murder suspect, as John, Lucy, and Lucy's son, Henry (Dylan Hughes), spend the holidays at a remote hotel in Yorkshire. It's the ultimate Agatha Christie-like setup, as a power cut creates a locked-room murder mystery. The killer probably didn't bank on John Taylor's presence, however. If anyone can solve a puzzling mystery like that, it's him.

Ludwig Is The Perfect Agatha Christie Homage

Even without David Suchet's exciting guest star role in the upcoming Christmas special, Ludwig is already the perfect Agatha Christie homage. Each episode features a new, perplexing mystery, influenced by many of Christie's trademark tropes and story structures, including, of course, the holiday episode's upcoming locked-door case. Christie's influence is all over Ludwig, but rather than feeling derivative, Mark Brotherhood's concept justifies its existence with Mitchell's fantastic leading character and season 1's clever (and hilarious) Parent Trap-esque premise.

Christie also loved a good amateur detective. While the fabulous Miss Marple is undoubtedly her most famous amateur investigator, characters like Tommy and Tuppence Beresford (soon to be the stars of their very own new series, BritBox's Tommy & Tuppence), Seven Dials' Bundle Brent, and other one-off sleuths like The Man in the Brown Suit's Anne Beddingfeld or The Sittaford Mystery's Emily Trefusis are also compelling examples of civilians who happen to become embroiled in murder and spy investigations (and prove to be very good at it).

John "Ludwig" Taylor is a fantastic amateur detective, one who has both a deep personal connection to the mystery that got him involved in crime-solving in the first place and a unique knack for sussing out the truth, even without the police's help. Mitchell plays the part with his natural comedic sensibilities but never forgets John's underlying anxiety and his genuine, if unvoiced, love for his family. Ludwig, like all of Agatha Christie's best stories, is the perfect blend of great character writing and exciting, twisty mysteries.

Ludwig Deserves To Be One Of The BBC's Most Successful Modern Detectives

Ludwig's popularity isn't all that surprising, and it certainly deserves to be one of the BBC's most successful modern detective dramas. The show is the perfect blend of serious crime and wonderful, laugh-out-loud comedy, as its fish-out-of-water premise forces John to partake in all sorts of schemes and situations far removed from the comfort of his cluttered living room. There's a great running gag of John being unable to properly drive or park his brother's posh, vintage car.

What the show does so cleverly is combine both a "case of the week" structure, as viewers are used to in similarly light-hearted, cozy crime dramas, with an overarching, complex conspiracy plot, as Lucy and John try to find out what happened to John's twin brother. While John is the show's star, he and Lucy are essentially a sneaky double act; she's the one who convinced him to come to Cambridge in the first place, setting the entire story in motion. Maxwell Martin is on top form, effortlessly charming, clever, and understandably worried about her husband.

Watching Ludwig is a genuine joy; the BBC's decision to renew the show is exciting. This is one of the first new non-adaptation shows in years with the potential to run just as long as shows like Death in Paradise, Midsomer Murders, and, of course, Agatha Christie's Poirot. Even if John and Lucy do find James soon, there will always be more cases to solve. First, though, let's see what happens in season 2 and during the upcoming holiday season.

Ludwig season 2 premieres on BritBox Tuesday, October 13, with new episodes dropping weekly. The Christmas special will arrive in December.
