The latest press release from the BBC on Merlin’s 12th (and as yet untitled) episode sees Morgana at the head of a vast Southron army, and a deadly net closing in around Camelot.
When the sorceress strikes, the ferocity of her attack forces everyone to run for their lives – even Arthur. But Morgana won’t let him escape that easily. And so begins a chilling hunt.
Can Merlin save the King from Morgana’s clutches? Or has Arthur’s luck finally run out?
