The 793rd episode of Doctor Who airs on BBC1 (the 95th episode since the series’ revival). 
The Doctor, having returned to isolation at a 13th century monastery, is jolted back into action by a phone call received on the TARDIS’ police box phone – a phone call from Clara Oswald, a perfectly ordinary 21st century girl whose death the Doctor has witnessed twice, neither time in the 21st century. When the Doctor traces her call and lands the TARDIS as the house where Clara is the nanny of the Maitland children, Artie and Angie. But Clara is in deadly danger: she’s connected her laptop to a wi-fi connection whose name is a series of alien symbols, and now her consciousness is being drained from her body by a robotic duplicate. The Doctor destroys the duplicate and reverses the process, vowing to protect Clara from dying yet another death. But the Doctor’s interference has attracted the attention of the shadowy organization using the strangely-named wi-fi routers to capture the consciousness of the human race, and steps are taken to prevent him from interfering again, including snaring Clara in a trap that finally succeeds in stealing her consciousness from her body. The Doctor is having none of it, but is unaware that one of his oldest enemies is behind it all.

Cast: Matt Smith (The Doctor), Jenna-Louise Coleman (Clara), Celia Imrie (Miss Kizlet), Robert Whitlock (Mahler), Dan Li (Alexei), Manpreet Bachu (Nabile), Sean Knopp (Paul), James Greene (The Abbott), Geff Francis (George), Eve de Leon Allen (Angie), Kassius Carey Johnson (Artie), Danielle Eames (Little Girl), Fred Pearson (Barista), Jade Anouka (Waitress), Olivia Hill (Newsreader), Isabella Blake-Thomas (Child Reading with Comic), Matthew Earley (Man with Chips), Antony Edridge (Pilot), Richard E. Grant (The Great Intelligence)
Notes: The Great Intelligence has doggedly pursued the Doctor through time and space in both his second (The Abominable Snowmen, The Web Of Fear) and eleventh (The Snowmen, The Name Of The Doctor) incarnations. The Great Intelligence has adopted the appearance of its previous victim, Dr. Simeon (The Snowmen), again played by Richard E. Grant. Celia Imrie is a familiar face on film and TV, having appeared in Bridget Jones’ Diary and in a blink-and-you’ll-miss-it genre role as a Naboo fighter pilot in Star Wars Episode I: The Phantom Menace. She also appeared in the eerie 1981 BBC drama The Nightmare Man, written by former Doctor Who script editor Robert Holmes and directed by classic Who frequent-flier Douglas Camfield. She has also appeared in Big Finish’s Doctor Who audio spinoff Counter-Measures and in the War Doctor audios with John Hurt.
Review: Hang on tight! Free from having to do most of the heavy lifting to introduce Clara as the new companion (after all, we’ve seen her live and die twice already), The Bells Of Saint John is frantic fun, showing an enemy that takes such fast and ferocious swipes at the Doctor that the Time Lord and his time machine barely have the time to keep up. It’s quite a bit of fun, and the “spoonheads” under Miss Kizlet’s command are a very creepy adversary. This, kids, is why you don’t go freeloading on someone else’s wi-fi bandwidth.
The real treat is Celia Imrie as this episode’s big bad (well, deputy assistant to the big bad, as it turns out); she’s one of those actors in the same category as Gareth Thomas: you would’ve assumed that she would have popped up somewhere in classic Doctor Who, but it never happened. Her skill in regressing Miss Kizlet to her lost childhood at the end is really one of the most chilling things about this story. We’ll just have to find it in our hearts to forgive the series’ various directors and casting departments, down through the decades, for 
not realizing that Celia Imrie was overdue to appear in Doctor Who.
The Bells Of Saint John takes off at breakneck speed and keeps getting faster from there. I wouldn’t want every episode of Doctor Who to be like this, but as diversions go, this episode is fun. It’s refreshing that Clara doesn’t want to go with the Doctor just yet – not a yes, not a no, but more of a “rematerialize when it’s convenient for me”.
