**AGATHA CHRISTIE’S MARPLE: A CHRISTMAS MYSTERY (2025)** follows the ever-sharp Miss Jane Marple as she becomes entangled in a chilling holiday puzzle that unfolds during a supposed season of warmth and joy. The film begins with Miss Marple being invited to the grand Winterleigh Estate to spend Christmas with an old acquaintance, Lady Constance Whitmore, a woman known for her extravagant celebrations and a family legacy clouded by rumors. Upon arrival, Miss Marple senses tension hidden behind the holiday decorations and polite greetings, as the Whitmore family members seem distant and strangely affected by the past. Their unease hints that Christmas at Winterleigh is not filled with peace but rather haunted by a long-buried secret.
The festive atmosphere quickly shatters when Lady Constance announces a shocking revelation about changing her will, leaving the majority of her fortune to a beneficiary unknown to the family. Before any further explanation, the lights go out during a sudden snowstorm, and when they return, Lady Constance is found dead beside the towering Christmas tree, seemingly from a fall. Yet Miss Marple immediately notices inconsistencies—a glass ornament shattered near her hand, footprints in the snow near the terrace door, and a ribbon from the tree tightly caught in her clothing. She suspects foul play behind what everyone hopes to label a tragic accident.
As the storm intensifies, the mansion becomes sealed off from the outside world, turning the holiday gathering into a tense masquerade of fear and accusations. Miss Marple quietly observes the family and guests: the resentful nephew who relied on the inheritance, the estranged daughter harboring a silent rage, the charming but suspicious estate manager, and a visiting priest with unclear intentions. Every smile conceals motives, and every alibi presents cracks. The mystery deepens when Miss Marple discovers old letters hinting at a scandal involving a lost child and a betrayal covered up decades earlier.
With her gentle demeanor masking her sharp intellect, Miss Marple pieces together the clues—the silent glances, the misplaced gifts, and the symbolic ornaments that reveal more than just festive cheer. As tensions escalate and the snowstorm isolates them further, she gathers everyone in the candlelit dining hall to reveal the truth. The murderer acted not out of greed, but revenge born from a lifetime of secrecy and abandonment, tied to the very person Lady Constance intended to help through her will.
The film concludes with Miss Marple reflecting on the fragile balance between justice and forgiveness, especially during a season meant for redemption. As the authorities finally arrive and the snow begins to melt, Miss Marple departs quietly, leaving the fractured family to confront the consequences of their long-hidden truths embraced beneath the glow of Christmas lights.
