NEW HORROR

Lot No. 249 Christmas Eve, 10pm, BBC2

A spine-chilling tale of terror has become a staple of the TV schedules at Christmas and this year's offering has all the qualities needed for edge-of-the-seat thrills.

Lot No. 249 is a short horror story by Arthur Conan Doyle, adapted by Sherlock's Mark Gatiss and starring Game of Thrones' Kit Harington and Slow Horses' Freddie Fox.

It revolves around three very different young academics at Oxford in 1881 - the unworldly Monkhouse Lee (Colin Ryan), manly Abercrombie Smith (Harington) and a strange and exotic scholar of Eastern languages, Edward Bellingham (Fox).
