Fiona Shaw as Carolyn Martens

Age: 55

Position: MI6 - head of Russia desk

Mantra: “Stay friends with Russia. That is the only rule.”

Charismatic, erudite, fiercely well read, and irreverent, Carolyn is a principled yet ruthless leader in her field. 

As a young agent on the ground in Moscow in the 80s she cultivated one of MI6’s most valuable assets and has since saved the world at least three times.

Naturally suspicious, a spate of unattributable assassinations around the world has prompted her to set up a secret unit to investigate.

Carolyn puts Eve in charge of the unit. She needs a group that can be invisible and work without the constraints of a typical MI6 unit.

She sees that Eve thinks outside the box and where everyone else has dismissed her, she admires and encourages her. She herself is not a maverick, but she’s very good at hiring them.

Carolyn is on to her fourth husband and her only child went to boarding school. She’s obsessed with her work.

Carolyn is played by Fiona Shaw, who Harry Potter fans will know as Harry’s disapproving Aunt Petunia.

Her other film roles include The Tree of Life, The Black Dahlia and The Avengers. On TV, she played Marnie Stonebrook in True Blood.
