The Madame Blanc Mysteries season 3 is back on our screens!

On May 23, 2023, it was confirmed that The Madame Blanc Mysteries had been recommissioned for a third full season. We've been looking forward to seeing Jean White try to solve another set of mysteries and murders in Sainte Victoire ever since.

Creator and star Sally Lindsay said of the show's renewal: "I am truly humbled by the love for our show and can't wait to give you lots more adventures".

Our first episode saw Jean investigating the death of a scientist who uncovered a rare treasure during a scuba dive, whilst the second saw her investigating the death of a gangster-turned-petty thief, a case which ended up being connected to the last-ever duel to take place in Sainte Victoire!

Here's what we know about the new season right now.

The international release date on Acorn TV is yet to be confirmed; we'll update this page with more information as soon as we know it.

The Madame Blanc Mysteries season 3 episode guide

Episode 1 (January 5, 2024): While a group of marine biologists are diving near Sainte Victoire, one of them, Gary, discovers a rare coin and pockets it. However, his good fortune is short-lived when he suffers a cardiac arrest in the water and dies. After showing Jean the treasure, Caron enlists her help to investigate what happened to Gary — were the scientists really checking the seabed for minerals, or did they have an ulterior motive? To help crack the case, Jean gets Dom to pose as a numismatist — an expert who authenticates coins for commercial purposes. Meanwhile, Gloria is fed up with her Uncle Trevor's antics and asks him to leave. He seeks refuge at the chateau with Judith and Jeremy, but quickly wears out his welcome there too...

Episode 2 (January 11, 2024): Early one morning in Sainte Victoire, Gloria's dog Douglas discovers a lifeless body with a fencing foil protruding from his chest, and in possession of an extremely rare, diamond-encrusted cufflink. Jean thinks the foil could be a 19th-century épée de combat and keenly scrutinises it for clues. The victim turns out to be George Allaire, a former big-time gangster now more known for petty thievery — and the case is connected to the last-ever duel to take place in Sainte Victoire. Meanwhile, Dom makes a surprising discovery about local bar La Couronne...

Episode 3 (January 18, 2024): When a woman is shot at the bus stop across the road from La Couronne, Caron is surprised to see her holding a shopping bag from Jean and Charlie's shop. The victim, Belinda, recently bought a Dickens first edition from Charlie, and was the nanny to a single father's young daughter. When a rare books specialist who previously owned the Dickens that Belinda bought comes forward, will she be able to shed some light on Belinda's tragic death? Meanwhile, Dom's Uncle Patrick returns to Sainte Victoire, and may be just the man that Judith and Jeremy need...
