Doctor Who returns to BBC One this Easter weekend, with Jenna-Louise Coleman joining Matt Smith as the Doctor’s newest companion, Clara Oswald.

Set in London against the backdrop of new and old iconic landmarks, The Shard and Westminster Bridge, ‘The Bells of Saint John’ is the first time fans get to see the Clara that will accompany the Doctor across Series 7 Part 2’s eight adventures. The episode will also establish a new nemesis, the Spoonheads, who will battle the Doctor as he discovers something sinister is lurking in the Wi-Fi.

Written by Steven Moffat, ‘The Bells of Saint John’ airs at 6.15pm on Saturday 30 March on BBC One. To whet your appetite, here are ten hints for the episode…

» Watch out ‘Rose’ and ‘The Eleventh Hour’ – you’ve got a real challenger for best companion introduction episode in ‘The Bells of Saint John’.

» A Time Lord who’s a monk. That seems familiar…

» It’s a snogging booth, it’s a mobile phone, it’s a weapon, it’s a garage. Can you guess what it is?

» A lot of tech geeks are probably going to have an aneurysm watching this episode, while a lot of campanology enthusiasts are going to be disappointed.

» Keep an eye out for a particular book. Someone’s doing pretty well in publishing.

» Lord Coe, please start putting a bid together for London to host the Anti-Gravity Olympics.

» Look! Up in the sky! Is it a bird? Is it a plane? Oh, it is a plane. Run!

» There’s never been a present-day set episode of nu-Who that’s used London as ambitiously or entertainingly as ‘Bells of St. John’ does.

» Did you just hack me?

» Take out advice and make sure you have a packet of Jammie Dodgers in – one scene might well give you a craving for them.
