Film Lot No. 249

249 is a supernatural television drama produced by the BBC based on the story "Lot No. 249" by British writer Arthur Conan Doyle, first published in Harper's Magazine in 1892. Adapted and directed by Mark Gatiss, it stars Kit Harington and Freddie Fox and was first broadcast on 24 December 2023 on BBC Two as part of the long-running A Ghost Story for Christmas series.

An Oxford student, Abercrombie Smith, recounts to his friend that his neighbour, Edward Bellingham, is using a revived Egyptian mummy to murder his social and romantic rivals. Following this meeting, Smith returns to his college, confronts Bellingham at gunpoint about his "perversions", and forces him to destroy the mummy and the associated artefacts. However, in the closing moments it is revealed that Bellingham has a second mummy – "Lot No. 250" – which he uses to continue his killing spree.
