Ludwig on BBC One: Series 1 recap as brilliant detective comedy returns for second run

It was arguably the best detective drama of 2024
Helen Fear

Ludwig was easily one of our favourite new series of 2024, and series 1 ended on quite the cliffhanger – so here’s a handy recap of series 1 ahead of the new episodes landing.

The brilliantly bonkers detective drama is back in August 2026, with some famous faces joining the line-up. And, this time, John ‘Ludwig’ Taylor won’t be pretending to be his identical twin brother James.

The first series landed on BBC One in October 2024. It introduced highly intelligent, hermit-like puzzler-setter John. But his reclusive life took an interesting turn when his twin disappeared.

In a bid to find out what happened to him, John was forced to pose as his brother, who just happened to be a DCI in the local police force. Drafted in by his pushy sister-in-law Lucy, John reluctantly assumed his brother’s identity as a detective on Cambridge’s major crimes squad.

And that’s when the fun and games began as he slowly began to piece together some clues to his brother’s whereabouts. Here’s a recap of what happened in Ludwig series 1, including that spine-tingling cliffhanger in the finale.

What happened in series 1 of Ludwig on BBC One?

Over six episodes, viewers saw socially awkward John attempt to crack the biggest puzzle of his life – the whereabouts of his missing brother James, a detective in the Cambridge Police. And James had left a trial of breadcrumbs to explain his vanishing to his bewildered wife and son.

Puzzle-setter John reluctantly stepped in to pose as his twin brother James in the hope of finding answers. All while having to deal with actual real life murders as an accidental detective…

Each episode saw John crack another clue as to his twin’s whereabouts. Here’s all the big revelations that you’ll need to be abreast of as series 2 begins.

Ludwig series 1 recap: Who killed Holly Pinder?

In the penultimate episode of Ludwig series 1, police IT technician Holly Pinder called Lucy out of the blue, requesting a meet up to share information. We saw Lucy head to Holly’s place, hoping to find answers to her husband James’ whereabouts.

However, the final episode began with a dead Holly bleeding out on her kitchen floor, and what looked like Lucy holding the bloody knife that killed her.

All evidence pointed to Lucy, the motive being James’ alleged affair with Holly (see below). DI Russell confronted John in an official police interview, asking whether he had ever been sexually involved with Holly. Of course, John couldn’t answer… He didn’t have a Scooby Doo who his brother had been dalliancing with.

Under pressure, John finally revealed the truth to Russell. He explained that he wasn’t James, and therefore couldn’t know for certain whether James and Holly had had an affair.

Of course, Lucy did NOT kill Holly. John quickly deduced who the real killer was. Adam, someone Holly had employed for her ‘real job’ had murdered her. We discovered that Holly sold police secrets, and blackmailed those she had information about.

Adam killed Holly when he realised she was cheating him out of the 50/50 split of profits they’d agreed on.

Did James Taylor and Holly have an affair?

John – and viewers – were shocked when Holly told John they’d enjoyed a frisson at the Christmas party (thinking he was James or so we thought).

A baffled John was left wondering if his twin James had cheated on his wife Lucy. But, no, he hadn’t.

In fact, Holly, despite being techie and not police, was the only person in the building who suspected John was not James. Whispering about their so-called kiss was a test.

When Holly contacted Lucy, she was planning to blackmail her with the knowledge that John wasn’t James.

Ludwig series 1 recap: Who was Roger Sinclair?

Roger Sinclair was a former journalist, blogger and conspiracy theorist. Holly Pinder had sold secrets to him.

We know Sinclair died in mysterious circumstances, and James had been first on the scene. He believed his death had been a professional hit. However, a specialist team was then brought in and James and his partner Matt were taken off the case.

When James later discovered that the crime scene report had been changed to look like a robbery, he flagged it up.

Then the contents of Sinclair’s house also went ‘missing’. Shortly after, Matt left his job and went into hiding, and James disappeared…

What happened to James Taylor?

At the end of Ludwig series 1, John’s twin James was still missing… But we had more of an idea as to why. In the closing minutes of Ludwig series 1, John received a voicemail from his twin brother James, who was in hiding. James explained that he’d left partly because he was unhappy in his marriage.

He told John he was like their father, who had abandoned them when they were children. He had simply left Lucy and their son Henry, having no idea that John would then take his place and try to solve the mystery.

However John realised the truth of the call. James was actually lying, and leaving him a coded message incase they were overheard. He had called himself the bowerbird… This subsequently led John to a book of birds which unlocked his cipher.

John, Lucy and Harry were led to a storage unit where all of Sinclair’s boxes had been stored away. John realised that Sinclair’s conspiracy theories may have had some truth to them – and probably led to his murder. Meanwhile, James watched on from afar…

Ludwig series 1 recap: Did John get found out?

John Taylor DID get found out at the end of Ludwig series 1. He confessed all after Lucy was wrongfully arrested for the murder of Holly Pinder.

However, when the truth came out, it was hard to fault John’s motives. After all, he’d single-handedly solved at least six crimes for the Cambridgeshire Police!

At the end of Ludwig series 1, John joined the force as an official consultant, meaning he no longer had to hide his real identity and pretend to be his brother.

John decided to stay put in Cambridge, to help Lucy and Henry work through Sinclair’s research…

Why isn’t Gerran Howell in Ludwig series 2?

David Mitchell returns to lead the cast as John Taylor, alongside the always brilliant Anna Maxwell Martin as James’ wife Lucy. Dipo Ola will also be back as DCI Russell Carter, with Dylan Hughes as Henry Betts-Taylor, Dorothy Atkinson as DCS Carol Shaw, and Karl Pilkington as DI Matt Neville. Ralph Ineson reprises his role as Chief Constable Ziegler, too.

But fan favourite Gerran Howell won’t be appearing in series 2 of Ludwig. Of course, this is because of his huge success in the States playing Dennis ‘Huckleberry’ Whitaker in The Pitt.

Talking about the David Mitchell crime drama, Gerran said: “Unfortunately I’m not doing series 2 of Ludwig, no. I hope the door is still open, because I really love that show.”

What is the plot of the returning BBC One series?

Series 2 will continue to follow John in his new role as the consultant for the Cambridgeshire Police. It will also concentrate on John’s continued efforts to find his brother James, and uncover the truth behind Roger Sinclair’s death. Undoubtedly, there is a bent copper lurking somewhere in the drama, too…

However, the heart of the show centres around John, and his sister-in-law Lucy. Are we the only ones who detected the possibility of romance between the unlikely pair? Or at least a rare friendship for the isolated loner…

A synopsis for series 2 tells us: “Picking up from where things were left at the end of series 1, master puzzle-setter John ‘Ludwig’ Taylor is now a Crime Scene Consultant working on ‘impossible’ crimes for the Cambridge Police Authority. No longer having to masquerade as his brother, he’s openly more ‘Ludwig’ than ever – brilliant at solving puzzles but hopeless at everything else.”

Of course we know that John’s identical twin brother is still missing. And now that John is an official employee of the station, he’s forbidden from using any police resources to look for James or uncover exactly what he was investigating…
