What to expect from the Death in Paradise Christmas special 

In the upcoming episode, the Honoré Police team get to work after a shocking murder takes place. The synopsis reads: "The office Christmas party of a lifetime takes a dark turn when four co-workers wake up to find a stranger dead in the pool of their Caribbean villa. DI Mervin Wilson and the team identify the murder weapon, but they’re left baffled when they find that it was locked in a drawer when the murder took place... thousands of miles away from the crime scene, in Swindon! Stuck in Saint Marie, the team calls on the help of a familiar face to crack the case. Meanwhile, Mervin’s anxiously waiting to hear back from his newly discovered brother, which prevents him from embracing Saint Marie's Christmas celebrations. Can Mervin resolve his family situation and get into the festive spirit – for the sake of his team and the island?"
