Is there a Madame Blanc Mysteries Christmas Special 2025?

Fans of The Madame Blanc Mysteries have good reason to be overjoyed as Acorn TV and Channel 5 have confirmed there WILL be a Christmas Special in 2025.

They announced the news on their official Instagram account. The post read: “It’s beginning to look a lot like Christmas and we have an early gift from Sainte Victoire – a sneak peek at our extra special feature-length Christmas special.”

In addition to four seasons, there have been three Christmas specials so far, going out in 2022, 2023, and 2024. Each one has run for 50 to 60 minutes.

However, the upcoming episode will be feature-length, so we’re expecting it to be around half an hour.

What’s the plot of the festive episode?

The extra-long festive instalment reunites our fan favourites Jean, Dom, Judith and Jeremy.

They attend an exclusive Christmas Eve event at the Musée de Sainte Victoire. But the festive mood turns dark when Jean is authenticating a newly acquired treasure only to discover a ticking bomb hidden inside.

Yikes.

With just 90 minutes until detonation, and the museum sealed shut, this is Jean’s “most perilous challenge yet”. Can she save the day?

Of course she can!
