The Madame Blanc Mysteries Season 4

Acorn TV officially releases its trailer for The Madame Blanc Mysteries Season 4, plus new photos, including the promised (threatened?) 75-year-old hotties on jet skis.

After a very long wait, Acorn TV finally announces the arrival of The Madame Blanc Mysteries for Season 4, just as summer hits its peak.

Much like co-production partner, Acorn TV, which rebranded in the spring of 20204 on the back of Harry Wild, Channel 5 is rolling out a rebrand as Madame Blanc returns.

The Madame Blanc Mysteries Season 4 announces the new additions for 2025, including a favorite from PBS' Ridley Road.

Acorn TV and Channel 5 confirm that cozy crime favorite The Madame Blanc Mysteries will return for a fourth season, and filming is getting underway in France.
