Let's just be real for a second. If you’ve spent any time on TikTok or scrolled through specific corners of Twitter lately, you’ve probably seen some convincing posters for A Discovery of Witches Season 4. They look official. They have the right font. They make your heart skip a beat because, honestly, who isn't still a little obsessed with Matthew Clairmont’s brooding energy or Diana’s transition from a hesitant academic to the most powerful weaver in existence? But here is the cold, hard truth: there is no Season 4.
At least, not in the way most people think.
The series, which captured the hearts of supernatural fans globally, was always designed as a trilogy. It followed the structure of Deborah Harkness’s All Souls book series perfectly. Season 1 was A Discovery of Witches. Season 2 was Shadow of Night. Season 3 was The Book of Life. When the credits rolled on that final episode in early 2022, the main arc of Diana Bishop and Matthew de Clermont was officially "wrapped." It’s done. The Covenant was abolished, the Congregation was reformed, and the biological secrets of the Blood Rage and the Weaver DNA were out in the open.
So why are we still talking about this in 2026? Because the "All Souls" universe is way bigger than just three books.
The Confusion Surrounding A Discovery of Witches Season 4
The internet has a funny way of manifesting things that don't exist. You’ve likely seen "leaks" or "announcements" claiming that Sky and AMC have greenlit a fourth installment. Most of this stems from a misunderstanding of how TV spin-offs work. When people search for A Discovery of Witches Season 4, what they are actually looking for—whether they know it or not—is an adaptation of Time's Convert.
Time's Convert is Deborah Harkness’s fourth book in this world. It isn't a direct sequel that continues Diana’s primary struggle; instead, it jumps around in time. It dives deep into Marcus Whitmore’s backstory—specifically his life during the American Revolution—and his attempt to turn Phoebe Taylor into a vampire in the modern day.
Is it a fourth season? Technically, no.
Could it be a new show? Absolutely.

The production companies, Bad Wolf and Sky Productions, have been notoriously quiet about a formal return to this world. However, the appetite is clearly there. The original series was a massive hit for Sky in the UK and a major draw for Sundance Now and AMC+ in the States. Leaving money on the table isn't usually how TV executives operate, but the complexity of bringing back a high-budget period piece during a shifting media landscape is a logistical nightmare.
Why the Story Felt Finished (But Isn't)
If you re-watch the finale of Season 3, it feels incredibly final. The "big bad," Peter Knox, is dealt with. Gerbert of Aurillac is sidelined. The daemons, witches, and vampires are finally allowed to intermingle without the threat of extinction or execution. It's a happy ending. Diana and Matthew are dancing in the hall of Sept-Tours, surrounded by family.
But fans of the books know that the ending of the show left out some massive crumbs.
For one, the twins—Rebecca and Philip—are just babies when the show ends. In the expanded lore, their development is a massive deal. They are "Bright Born," a mixture of all three species' traits. This isn't just a cute plot point; it's a fundamental shift in the supernatural biology of their world. A hypothetical A Discovery of Witches Season 4 or a spin-off would almost certainly have to grapple with the reality of raising children who can literally rewrite the laws of magic while teething.
Then there’s the Gallowglass problem. Steven Cree’s portrayal of the tattooed, leather-jacket-wearing vampire was a fan favorite. His unrequited love for Diana was heartbreaking. In the show, he sort of just... rides off into the sunset. It’s a bit of a letdown. In a potential continuation, Gallowglass is the character everyone wants to see more of. He has centuries of history that the show barely scratched.
The Reality of the "All Souls" TV Expansion
Let’s look at the facts. Deborah Harkness has been busy. She recently released The Black Bird Oracle, which is the fifth book in the series. This book actually picks up with Diana Bishop again, years after the events of The Book of Life.

This changes the "Season 4" conversation entirely.
If the producers wanted to bring back Teresa Palmer and Matthew Goode, they now have actual source material that continues Diana and Matthew's story. The Black Bird Oracle dives into Diana's darker family history and the higher powers of the witch world. It's grittier. It's more mature. It moves away from the "forbidden love" tropes of the first three seasons and into something much more cerebral and ancient.
So, could we see a revival?
- Contractual Hurdles: Matthew Goode and Teresa Palmer are busy. Palmer has been working on various projects in Australia, and Goode is... well, he’s Matthew Goode. Getting them back together requires a massive budget and a gap in their schedules that didn't exist two years ago.
- Production Rights: Bad Wolf, the production company, was acquired by Sony Pictures Television. This kind of corporate movement often puts "on the fence" projects into a state of limbo while the new bosses figure out what’s profitable.
- The "Spin-off" Strategy: Instead of a direct A Discovery of Witches Season 4, the industry rumor mill suggests a limited series format. Think of it like how The Walking Dead branched off into smaller, character-focused shows. A "Gallowglass" prequel or a "Marcus and Phoebe" miniseries is much more likely than a full-blown fourth season of the flagship show.
What Most People Get Wrong About the Ending
People often think the "Book of Life" was just a MacGuffin. It wasn't. By the end of the series, Diana is the Book of Life. The information is literally written into her skin and soul.
This creates a bit of a narrative problem for a Season 4. How do you create stakes when your protagonist is essentially a living god? This is why the show ended where it did. To keep the tension high, you'd have to introduce a threat so massive it makes Peter Knox look like a toddler with a wand.
Harkness did this in her later books by introducing the idea of "The Higher Powers" and deeper secrets within the de Clermont family that even Baldwin didn't know about. Honestly, the show barely touched the political infighting of the vampire world. There are thousands of years of grudges that haven't been explored.

The Role of the Fandom in a Potential Revival
Don't underestimate the "Netflix Effect." Even though the show started on Sky and AMC, its move to various streaming platforms has given it a second life. New viewers are discovering the series every day. This "long-tail" viewership is exactly what streamers look for when deciding what to reboot.
If you want more content, the best thing you can do isn't looking for fake trailers on YouTube. It’s supporting the official releases. The sales of The Black Bird Oracle are a direct metric that TV executives use to gauge interest in a continuation.
Final Verdict on Season 4
Is it coming? Not this year. Probably not next year either.
But is the world of A Discovery of Witches dead? Hardly. With the publication of new books and the ongoing demand for "Adult Fantasy" (that isn't just grimdark like Game of Thrones), the probability of a return to Sept-Tours is higher now than it was when the show ended.
Just don't call it Season 4. It will likely be a new series title, a "rebranding" that allows the creators to bring in new cast members while keeping the original stars for recurring roles or cameos.
What You Can Do Right Now
If you're feeling that void that only a 1,500-year-old vampire and a historian witch can fill, here is your roadmap:
- Read Time's Convert: It bridges the gap between the original trilogy and the new era. It gives you the Marcus backstory you didn't know you needed.
- Pick up The Black Bird Oracle: This is the actual "what happens next" for Diana and Matthew. It’s the closest thing you will get to a Season 4 script.
- Watch the "All Souls Con" panels: There are plenty of interviews with the cast and Deborah Harkness where they discuss the "unfilmed" parts of the lore.
- Ignore the Fan-Made Trailers: If you see a trailer on YouTube that uses clips from The Offer or Hacksaw Ridge to make it look like Matthew and Diana are back, it's fake. Save yourself the heartbreak.
The magic hasn't left the building; it’s just waiting for the right moment to manifest again. Keep an eye on official announcements from Sky TV or Deborah Harkness’s verified social media channels. Anything else is just smoke and mirrors.
Next Steps for Fans: To stay truly updated, follow the production company Bad Wolf on social media. They are the gatekeepers of the visual "All Souls" world. Additionally, checking the UK Production Weekly listings can often tip you off to "working titles" that might secretly be the return to this universe long before a public press release.
