CASTLE: MISTLETOE & MURDER (2026)

Holiday Mystery • Romantic Crime • Cozy Thriller

The city thatnever sleeps is blanketed in snow—but beneath the twinkling lights of Christmas, a dark truth lurks. When a high-profile socialite is found dead in a luxury penthouse, the investigation quickly escalates into a high-stakes game of secrets, lies, and betrayal.

Castle and Beckett—reunited after months of tension—are thrust back into the world of crime and chaos they once thrived in. But this time, it’s different. The holiday season adds a complicated layer to the case, where every suspect is a smiling face behind which lies an agenda.

With an outsider—Detective Morgan Shaw—gaining more influence and playing the game with a cool detachment, Castle and Beckett find themselves struggling not only against the suspects but also against the brewing storm of their own unresolved feelings. As they dig deeper, they uncover a dangerous connection between the murder and a decades-old scandal that could shatter some of the city’s most respected families.

The cozy, festive backdrop contrasts sharply with the ever-growing tension. Ice-cold smiles and tight-knit communities give way to long-buried grievances and shocking revelations. The closer they get to the truth, the more Beckett and Castle realize they might not be the only ones with secrets to hide.

Can they unravel the mystery before more lives are destroyed—or will their rekindled romance be the next thing to fall apart?

With pulse-pounding action, twists that will leave you gasping for breath, and the fiery chemistry fans have been waiting for, Mistletoe & Murder will keep you on the edge of your seat until the last snowflake falls.

Everyone has something to hide… and the truth could be more dangerous than they ever imagined.
