"The Bells of Saint John" is the sixth episode of the seventh series of the British science fiction television programme Doctor Who.

Finding a third version in present-day London, he soon becomes involved in saving her and the rest of Earth from Miss Kizlet (Celia Imrie) and her employer, the Great Intelligence, as they use the world's Wi-Fi to upload people to a datacloud via robots known as Servers, casually referred to as Spoonheads.

[2] The Doctor has retreated to a monastery in Cumbria in 1207 to contemplate the mystery of Clara Oswald, a woman he had met twice previously but who died both times.

Arriving in present-day London, the Doctor finds Clara's mind being "uploaded" via a mobile robotic server disguised as a young girl using the Wi-Fi.

The Doctor encounters people inside the café under the control of Miss Kizlet, who explains that living human minds are being fed to her client.

Writer Steven Moffat described the premise as the traditional 'Doctor Who' thing of taking something omnipresent in your life and making it sinister, if something did get in the Wi-Fi, we'd be kind of screwed.

'[7] However, he denied that his intention was to give a warning about technology, but rather tell an adventure story about a "new way [for aliens] to invade" based on something viewers were familiar with.

[8] Producer Marcus Wilson suggested that the episode be an "urban thriller", as the story would already be set in contemporary London to introduce Clara and the Wi-Fi monsters.

He described it as "a hugely enjoyable episode that revels in its modern London setting", praising the way its ideas were realised visually on-screen.

[33] MSN's Hilary Wardle gave "The Bells of Saint John" episode four out of five stars, noting that it moved at a fast pace and the plot was similar to "The Idiot's Lantern" (2006) but was "very well done".

[34] Ben Lawrence, writing in The Daily Telegraph, gave the episode four out of five stars, saying that it had much to "enthral" a present-day viewer and showed how Doctor Who was constantly reinventing itself.

[35] A similar statement was made by Euan Ferguson of The Observer, who also wrote that the episode was "splendid" with good villains, though he felt that the plot was "insanely complicated" and hard to understand.

[36] Digital Spy's Morgan Jeffery also rated "The Bells of Saint John" four stars, feeling that the threat "leaves a little to be desired" and the Spoonheads' physical appearance was not memorable.

Club's Alasdair Wilkins gave "The Bells of Saint John" a grade of B, explaining that the plot suffered just as previous companion introductions had because the threat was secondary to establishing Clara.

[39] He also wrote that the episode "struggles to make all its chosen genre elements compelling" and was not positive towards the menace of the Wi-Fi and questioned how realistic the technology seen was.

[19] Neela Debnath in The Independent echoed similar sentiments, feeling that it did not live up to the hype and reused several elements from previous episodes.

[40] Jon Cooper of the Daily Mirror wrote that "The Bells of Saint John" "had its moments" but "as a whole it didn't reach the heights of previous episodes".

While he welcomed the departure in tone, he felt that the set-pieces were shoehorned in, and also expressed concern that Clara, despite Coleman's success, was too similar to previous companion Amy Pond (Karen Gillan).
