The epic fifth series of fantasy drama Merlin continues on BBC One this weekend and when Gwen is snatched from Camelot without warning, Merlin knows there can be only one person responsible: Morgana.

Arthur is determined to rescue his Queen – but it’s not going to be easy, for she is locked in the Dark Tower, a place that haunts the dreams of men.

‘The Dark Tower’ airs at 8.05pm on Saturday 10 November on BBC One. To whet your appetite, here are ten hints for the episode…

» What will drip on a regal countenance?

» Red cloaks can be a touch impractical at times!

» ‘I don’t know what I’d be if it wasn’t for her.’

» Which Knights will suffer night terrors?

» Sword quality is not what it used to be.

» What will spook the horses?

» Is rhyme really better than riddle?

» Who attained their cub-scout badge for advanced tracking skills?

» ‘I know it’s not you, I know it’s not you!’

» The word ‘impenetrable’ will clearly need redefinition.
