after the contemporary "Rose" and far-future "The End of the World". The episode also reintroduces the TARDIS' habit of taking the Doctor to the wrong places, something that had not yet happened in the revived series. Davies felt that it was important for an episode to be set in Cardiff as that is where the new series is produced, and wanted the story to be set in Victorian times and feature Charles Dickens. Davies' original brief also included "fake mediums", and Gatiss originally set it in a "spiritualist hotel", which had fake mediums (such as a character named Mrs Plumchute) on the lower floors and Mr Sneed on the top, though he was unaware he was a true medium. However, Gwyneth became a more popular character with the production team, and she took on much of the medium role. Gatiss was also more interested in possession and zombies. Mrs Sneed was another character that was cut out of the episode; Gatiss believed she was unnecessary as Gwyneth was the "heart" of the story. The working titles for this story included "The Crippingwell Horror" and "The Angels of Crippingwell". The original draft was grimmer, including details about the previous death of Gwyneth's younger brother, but in subsequent drafts the story became more of a "romp". Gatiss stated that the name "Gelth" simply popped into his head. Gatiss was encouraged to personify the Gelth, which he originally questioned because he felt that monsters whispering "Doctor" was a cliché; producer Phil Collinson remarked that perhaps it was a cliché because it worked well. The Rift was added into the plot to simplify the Gelth's origins. Gatiss originally resisted having Dickens star in the episode, as traditionally the Doctor only mentioned meeting historical figures, but he eventually warmed to the idea. As A Christmas Carol fan, Gatiss wanted to set the episode at Christmas. He later realised that Dickens' journey in the episode mirrored that of Ebenezer Scrooge. In one scene, Gatiss wanted the knocker on a door behind Dickens to briefly show the Gelth's face in reference to A Christmas Carol, but this visual effect was not done. The episode originally began in the TARDIS, as Gatiss wanted the first glimpse of 1860 to be through Rose's eyes. While this changed, Gatiss still wanted to show how great travelling in time is. It was scripted that snow would blow into the TARDIS when
