Despite the genre's long history in Britain, espionage and assassin thrillers are having a fresh moment of late, with the likes of Day of the Jackal actually zapping some dramatic energy into the grey, contrastless landscape outside (hello, writing from London).

The latest, Black Doves, not only infuses the year's colder months with sultry stress and action, but it's a fittingly festive delight, with Christmas trees and twinkling lights bedazzling murder scenes, clandestine meetings, and violent fist fights. Festive viewing need not be contained to the cosy realms of The Holiday or easy viewing Netflix specials (though I love these too). If you're more into thrillers but still want the seasonal theming, fire up Black Doves.

What is Black Doves about?

Created and written by Joe Barton (The Lazarus Project) and directed by Alex Gabassi (The Crown) and Lisa Gunning (The Power), Black Doves is an espionage thriller that just happens to be set at the end of December — yes, just like Die Hard, but this is a Christmas action watch you'll have an easier time defending as one.

The series stars Knightley as Helen Webb, philanthropist, mother, and spy for a private espionage company called the Black Doves, who work for the highest bidder. Undercover, she's married to defence secretary Wallace Webb (Broadchurch's Andrew Buchan) who's completely unaware of that last part, as are their children. When the Ministry of Justice's Jason Davies (Bullet Train's Andrew Koji) turns up assassinated on the banks of the Thames, Helen's carefully crafted cover sits on a knife's edge as she investigates. Yes, she knew Jason, and yes, it's the spark of a potential geopolitical crisis that'll have Helen reunited with her old colleague, triggerman Sam (Ben Whishaw), to uncover answers. And they're both reporting to the show's M, spymaster Reed (Happy Valley's Sarah Lancashire).

It's classic thriller material here: Seemingly unconnected high profile murders abound! The Chinese ambassador is dead and his daughter is missing! There's an assassin in the kitchen! And for reasons you should just enjoy, it's all set at Christmas time — we're talking rainy cabs through Oxford Street's lights, shady dealings within the bauble-clad Liberty department store, furious kitchen fights with candy-striped tea towels, tinsel surrounding the overtly signed ROASTED CHESTNUTS being sold on the Thames. Characters even wear tinsel scarfs and Santa hats firing guns on a job.

While Black Doves by no means reinvents the espionage thriller, the series boasts solid twists, strong action, and electric performances from its superb cast, all of whom seem to have a genuinely great time. And at the heart of it all are two delightful BFFs.

Knightley and Whishaw have effortless chemistry as old espionage colleagues, with flashbacks giving them plenty of bickering banter, training moments, close calls, and in-jokes to build a long friendship for their characters. For the most part, this is Knightley in Official Secrets mode, not her formerly signature period drama mode, and she makes her own mark on the well-worn character of a covert operative (think Homeland, The Americans, with less traumatic exploration of secret identity guilt). Mastering hand-to-hand combat and unnerving interrogations, delivering lived-in spy dialogue, and downing tequila "like a Russian submarine captain" Knightley seems to have a ball as Helen.

Meanwhile, a marmalade-free Whishaw delights as heart-of-gold assassin Sam, a far cry from his previous spy thriller work as James Bond's gentle gadget master Q. Like Eddie Redmayne's character in Day of the Jackal, Sam's murder work is meticulous, cold, and nonchalant, while his social self is debonair, warm, and vulnerable. Swilling champagne in most scenes, understandably pining for his Big Ex, and grappling with murdering people for money, Sam has to figure out what his code is. But Knightley doesn't get to do all the hand combat, as Whishaw gets to throw punches too.

Lancashire, meanwhile, is a brilliant pick for the show's spymaster, her steely glare and subtle threat ringing through every scene and unsettling her reports. They're all backed by an excellent supporting cast, with highlights including screen legend Kathryn Hunter (The Front Room) as shrewd triggermen manager Lenny Lines, It’s a Sin star Omari Douglas as Michael, the love of Sam's life, and Fifteen-Love's Ella Lily Hyland as cold young assassin Williams. Douglas in particular is a sublime romantic lead, and scenes with Whishaw simmer with longing and love lost.

If you're looking for a festive treat with more hired killers, less small town Christmas festivals in barns, Black Doves is a riveting watch that just happens to come with decked halls. A true gift.
