The Madame Blanc Mysteries Christmas special cast: Every character featured in the crime comedy series and the actors behind them

Christmas and the holiday season of 2025 are lit up as Acorn TV’s The Madame Blanc Mysteries Christmas special is set to offer viewers a longer story told in two episodes, making the festive mystery even more exciting to watch. The Madame Blanc Mysteries Christmas special, led by Sally Lindsay as Jean White, was aired internationally on Acorn TV on November 30 and December 1. The two-part episode was then scheduled to air for the UK viewers on Channel 5 on December 15, and the upcoming second half is set to premiere on December 22. 

The special follows Jean White, an antiques expert and amateur detective, as she attends a glamorous Christmas Eve event at a local museum in the French village of Sainte Victoire. Jean is there to examine a rare antique (an Ormolu box) believed to be valuable. But the celebration quickly turns into a nightmare when Jean discovers that the box hides a “ticking bomb.” The museum is locked down, and everyone inside has 90 minutes before it explodes.

Set in the festive Christmas vibe, Jean and her friends are trapped, and with time running out, she must use her knowledge of antiques and her sharp detective skills to figure out who planted the bomb and why.
