1. Sarah Lund (The Killing)
She cracks crime without cracking a smile – and now Lund (Sofie Grabol) is back to spot the essential details that others don’t. Enigmatic.
2. Jane Tennison (Prime Suspect)
She battled alcohol and sexism, but Tennison (Helen Mirren) also proved herself to be one of the Met’s canniest officers. Ballsy.
3. Olivia Benson (Law & Order: SVU)
Born following her mother’s rape, Benson (Mariska Hargitay) is the empathetic voice of the victims. Tough but tender.
4. Christine Cagney and Mary Beth Lacey
One was sassy and single, the other a homebody with an ever-expanding family – together they made the perfect partnership. NY’s finest.
5. Suzanne “Pepper” Anderson (Police Woman)
In the US’s first major drama series with a female star, Angie Dickinson often went under cover as both hooker and stripper. Trailblazer.
The Killing II begins with a double bill on Saturday November 19 from 9pm on BBC4
