Renowned astronomer Marmion (Leo Gregory) gathers the Royal household to his impressive observatory in a transformed old fort to watch a solar eclipse.

Rochefort (Marc Warren) along with The Musketeers escort them but could never have predicted the twist in fate that ensues and the impossible choices that must be made. Who is Marmion really and what is his game?

The Musketeers are forced into the fight of their lives with dramatic consequences. Will they accept Milady’s (Maimie McCoy) help despite their loathing and mistrust of her? It might be their only chance to save the King, Queen and themselves.

The Musketeers Series 2, episode 6: ‘Through a Glass Darkly’ airs on Friday, 20th February at 9pm on BBC One.
