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...

Episode 4 (January 25, 2024): Judith has invited fashion designer Violet Oliver (Lisa Faulkner) to showcase her latest collection at the chateau, but the fashion show takes an unexpected turn when the event is plunged into darkness and Violet takes a terrifying tumble from the balcony. Against all odds, she survives the fall, and Jean embarks on a mission to discover who tried to push Violet to her death. Elsewhere, Charlie gets a sense of déjà vu when Gloria's boyfriend Cooper visits the antique shop. 

Episode 5 (February 1, 2024): Judith's birthday celebrations take an unexpected turn when Jeremy arranges a surprise dinner at one of Sainte Victoire's finest restaurants, attended by Jean, Dom, and two of her oldest friends, sisters Nancy (Lisa Maxwell) and Delphine (Julie Graham). When Nancy leaves to go to the bathroom during the meal, Jeremy's phone pings with a menacing message revealing Nancy has been tied up and held to ransom! Jean and Dom get the search underway to find out where Nancy has been taken — but can they find her before it's too late?

Dom (Steve Edge), Delphine (Julie Graham), Nancy (Lisa Maxwell) and Jean (Sally Lindsay) sit around a table in a fancy restaurant, decorated with balloons and flowers, and with a balloon arch in the distance. They all have expressions of delight on their faces.

Episode 6 (February 8, 2024): In 1995, Patrick was involved in a card game at La Couronne with gangster Sonny Montario (Sanjeev Kohli) where Sonny won a clue to untold riches hidden somewhere in the village — but when it turned out to be a poem, he became angry and struck out at fellow player Gabriella, who died. Patrick was responsible for identifying Sonny in a police line-up, and when he discovers that Sonny is about to be released from prison and is coming to Sainte Victoire to claim his prize, he's worried that his life is in danger. Jean and Dom set out to decode the poem and find the hidden treasure to save Patrick's life, but while Jean throws herself into the mystery, Dom's distracted by a health worry...
