Death in Paradise Christmas Special 2025: Sun, Mystery and Family Drama

26 December 2025 Television

The Return of Festive Crime on Saint Marie

The Death in Paradise Christmas special 2025 will air on BBC One on Sunday, December 28, bringing viewers back to the sun-soaked Caribbean island for another dose of seasonal murder mystery. This year’s festive instalment continues the tradition of blending crime-solving with holiday cheer, as Don Gilet returns as Detective Inspector Mervin Wilson to connect with his newly discovered brother.

A Complex Case and Personal Drama

The plot centres on a challenging investigation as DI Mervin Wilson and the team must solve one of their most challenging cases yet when a man is found shot dead after a raucous office Christmas party. However, Mervin’s focus is divided. Mervin’s anxiously waiting to hear back from his newly discovered brother, which prevents him from embracing Saint Marie’s Christmas celebrations. This emotional subplot stems from the series 14 finale, where Selwyn dropped the bombshell on Mervin that he’s spoken to Solomon, and that Solomon is Mervin’s brother.

Star-Studded Guest Cast

The Christmas special boasts an impressive lineup of guest stars. Josie Lawrence plays Marjorie Dodds, Kate Ashfield will play Helen Dugdale, and Pearl Mackie is heading to Saint Marie as Karen Hickson. The regular cast returns, with Shantol Jackson as Detective Sergeant Naomi Thomas, Elizabeth Bourgine as Catherine Bordey, Ginny Holder as Officer Darlene Curtis and Shaquille Ali-Yebuah as the newly promoted Officer Seb Rose.

Why This Episode Matters

This Christmas special represents a significant moment for the long-running series, now heading into its 15th season. The episode explores DI Wilson’s character development as he navigates both professional challenges and personal revelations. For fans in the UK seeking festive television that combines tropical escapism with classic whodunit storytelling, this special offers the perfect blend. It will also be made available to watch on BBC iPlayer, ensuring viewers can enjoy this festive treat at their convenience throughout the holiday season.
