Mark Gatiss’ adaptation of the Arthur Conan Doyle short story comes to BBC Two this Christmas, starring Kit Harington and Freddie Fox.

It's 1881. Old College, Oxford plays host to three very different young academics: Abercrombie Smith (Kit Harington), a model of Victorian manhood, clean of limb and sound of mind; Monkhouse Lee (Colin Ryan), a delicate and unworldly student from Siam; and the strange and exotic Edward Bellingham (Freddie Fox), whose arcane research into Ancient Egypt is the talk of the campus. Could Bellingham’s unnatural experiments bring the breath of life to the horrifying bag of bones tagged Lot No. 249?

An end-of-Empire chiller, Lot No. 249 stars Kit Harington, Freddie Fox, Colin Ryan, John Heffernan, James Swanton, Jonathan Rigby and Andrew Horton.

Watch A Ghost Story for Christmas: Lot No. 249 on BBC Two and BBC iPlayer from 24 December at 10pm
