Those classic Christmas ghost stories of old return this year with the three-part Crooked House.

From The League of Gentlemen's Mark Gatiss, the drama revolves around the discovery of a big old knocker and the ghostly connections it has. Each of the three episodes is set at a different time in the knocker's history - the first is in Georgian times, the next is in the 1920s and the final is in the present day.
