Catherine Fedden (played by Hayley Atwell
Toby's self-harming, manic-depressive younger sister. She's sparky, amusing, dangerous, sexy, and rude to the Feddens' friends. When "up", she is a loose cannon, speaking the truth where no one else dares.
Her increasingly heavy dosage of lithium suggests that the Feddens desire to silence these "eccentric outbursts" and maintain the family's fragile status quo. She is the family's conscience, and when events reach breaking point, it is Catherine who exposes the lies that both the family and Nick have been living.
Catherine is a beguiling, damaged and needy character, with a string of disastrous relationships behind her. She forms the closest bond to Nick because he is intelligent and sensitive enough to understand her. Yet it is she who finally betrays him.
Hayley's only previous on-screen dramatic role was an uncredited appearance as Sabrina Guiness in Charles/Camilla docu-drama Whatever Love Means. Though she did also appear in the Pringles advert where the dogs have a party in their kennel.
She studied at the London Guildhall School of Music and Drama*, during which time she performed in plays including I Capture the Castle and Shakespeare's A Winter's Tale. She recently played Bianca in a well-regarded Royal Shakespeare Company production of Women Beware Women, a bloodthirsty Jacobean tragedy.
