Owen McDonnell as Niko Polastri.

Age: 45

Position: Maths teacher, bridge teacher, devoted husband.

Wants: A quiet life of bridge, home cooking and eco-friendly DIY.

Eve’s husband Niko is strong, moral and appreciates the simple things in life. 

He was born in England to Polish immigrant parents and grew up on the wrong side of the tracks.

He has an aversion to violence, and can’t understand Eve’s fascination with darkness and criminality. 

He’s smart, compassionate and, though he perhaps can’t admit it to himself, prefers his wife in a boring desk job than in close proximity to danger.

Deep down he knows there is something darker living in Eve. He dislikes her flippant humour towards violence and her fascination with assassins.

As a couple they are practical and loving. They speak regularly and tell each other everything. 

He is a reliable wall, standing solidly behind her.

Niko is played by Owen McDonnell, who has also appeared in the TV series Spooks, Silent Witness, and Paula
