Detective Inspector Max Arnold (Adrian Scarborough) is officiallyback on the case withThe Chelsea Detective, which is getting a particularly jolly episode just in time for the holiday season. Fans have been eagerly awaiting the third season of the beloved fan-favorite British mystery series, and that wait is finally almost over. Season 3 ofThe Chelsea Detectivewill be kicking things off with a brand-new Christmas Special, which will see Max Arnold start what could be his most cold-hearted mystery yet.

Picking up where Season 2 left off, the trailer forThe Chelsea DetectiveChristmas Special begins with the famously ambivalent Max Arnold defending his choice in Christmas decor, which includes a rather pathetic-looking Christmas tree. However, the Detective Inspector isn’t able to spend the holidays in his cozy abode, as not even crime sleeps soundly during the season. Max Arnold is brought in to solve a new case that, predictably, involves murder, drugs, and social media bullying. What follows is bound to be a very long night that will see Max attempt to balance his personal life and the holidays with his unbelievable dedication to solving mysteries and stopping crime.
