Walker played fan favourite Ruth Evershed for six years in the stylish and much-missed spy drama Spooks.

Introduced in the show’s second series, Ruth became a trusted member of the MI5 team and had an ongoing romantic storyline with Harry Pearce (Peter Firth) that concluded in the show’s finale in the sort of shock moment that had become a Spooks trademark.

Last Tango in Halifax

Sally Wainwright’s much-loved comedy drama series, which began in 2012, saw Walker starring alongside Derek Jacobi, Anne Reid and Sarah Lancashire for five seasons

Walker claimed she shocked to land the part of a “fabulous, aggressive, emotional sheep-farmer”, but it turned out to be perfect casting in the inter-generational Yorkshire saga.

Scott and Bailey

Before Unforgotten stole its crown, Scott and Bailey was ITV’s most underrated crime drama with Suranne Jones and Lesley Sharp as the titular detectives.

Walker appeared in the show’s third season, playing Helen Bartlett. Her recurring character had a harrowing storyline, uncovering her involvement with her parents’ dark crimes.

The Split

Walker leads the cast of this BBC legal drama as Hannah Stern, a highly-sought after family lawyer who specialises in divorce cases.

Stern is a departure from Walker’s better known performances - all glamour, heels and highlights - and her entanglements with her husband (Stephen Mangan) and her ex (Barry Atsma) made the show an addictive treat.

Inside No.9

Reece Shearsmith and Steve Pemberton's comedy anthology series is always darkly delicious and Nicola Walker’s appearance in season 4’s To Have an to Hold is a classic episode.

Playing a bored wife of a wedding photographer (Pemberton), Walker goes all in to play the sad wife attempting to inject some new frisson into their love life. As with all episodes of Inside No.9, not all is quite as it seems and Walker delivers the closing sequence with style.

Nine things you didn't know about Inside No.9


It only got six episodes, but Abi Morgan’s River was an underrated gem. Stellan Skarsgard played the lead, Detective Inspector John River, but Nicola Walker stole the show as his late colleague DS Jackie ‘Stevie’ Stevenson.

A study of loss, grief and also just a cracking crime drama, the series was heavily influenced by Nordic noir and deserved much more attention that it got when it was first released in 2015.

River is available on BritBox and available to buy and own in the BT TV Store
