Doctor Who tackles a good old-fashioned ‘base under siege’ tale on Saturday night, with Being Human creator Toby Whithouse penning a spooky undersea adventure.

‘Under the Lake’ has ghosts, gags and a helluva ending. No spoilers – but here are ten tantalising teasers.

1. The psychic paper makes a comeback.

2. “I’ve never actually met a proper ghost.”

3. Something is deadlock sealed.

4. “It’s been deleted.”

5. The Doctor once crossed paths with a soul diva.

6. “Don’t leave me hanging.”

7. Sorry haterz – the sonic sunglasses are back.

8. “We’re going to do the impossible.”

9. That cliffhanger is sure to spook the little ‘uns.

10. “I was begging for the brush of death’s merciful hand.” (It’s not much the line as the set-up.)

Doctor Who continues this Saturday (October 3) at 8.25pm on BBC One
