Lot 249 reflects the Victorian obsession with everything to do with ancient Egypt. This story was set in 1884, two years after the Anglo-Egyptian war, a conflict which perhaps had an influence on the tone of this story.

The Victorian fear of being randomly garrotted is reflected in the reaction to a mummy attack in Lot 249.

The character of ‘The Friend’ in Gatiss’s adaptation is clearly Sherlock Holmes. If the dialogue doesn’t give it away, his appearance bears unmistakable similarity to Sherlock Holmes in the classic Strand Magazine illustrations by Sidney Paget, particularly this one.

Lot 249 was featured in the 1990 comedy horror anthology Tales from the Darkside. Starring Christian Slater and Steve Buscemi, the scene in which Smith finally confronts Bellingham is on Youtube, and makes quite a watch!
