Black Doves is back on Netflix, and its spy is in a worse position than the one she started in. Keira Knightley returns as Helen Webb, a politician’s wife who has spent years passing state secrets to the Black Doves, the covert outfit that trades in other people’s intelligence. Ben Whishaw is back as Sam, the contract killer who is her oldest friend. This time the man Helen has been spying on, her husband Wallace, is preparing to become Prime Minister.

That detail carries the whole second season of the British spy thriller. In the first run, Helen’s double life was a private betrayal with a domestic address. A husband on his way to Downing Street changes the value of the same habit. Whatever she passes on now concerns the man about to run the government, and every lie she tells at home is told to someone about to be surrounded by the country’s tightest security. Netflix’s synopsis says it plainly: she is walking “a more treacherous line than ever”.

Helen moves up, Sam moves down

Joe Barton, who created the series and writes it, opens the season by pulling his two leads apart. The logline sends Helen upward, toward the most watched address in Britain. It sends Sam the other way. The once high-end triggerman is now, in Netflix’s words, “reduced to lonely drinks in Soho bars and low-rate hits”.

It is a structural choice before it is a plot point. The first season ran on the friendship between two professionals who trusted each other more than anyone they lived with, and the new synopsis keeps that bond as its spine: Helen reunites with Sam, and the search for answers that follows exposes betrayals. Starting them at opposite ends of London gives the reunion a price. One of them has never had more to lose. The other has almost nothing left.

Sam is also the one being offered a way out. Sam Riley, new to the cast, plays Patrick, an emissary from a mysterious organisation who offers Sam a lifeline. Netflix has not said who that organisation is or what the lifeline costs.

The threat moves inside the Black Doves

The larger shift is where the danger comes from. The season’s synopsis places it inside the organisation itself. Mrs Reed, the handler played by Sarah Lancashire, is caught in a ruthless plot to undermine her position in the Black Doves. For Helen that is not office politics. Reed is the person who runs her, and the premise suggests that a handler under attack is a handler whose agents become leverage.

Two of the new names sit on that fault line. Babou Ceesay plays Mr Conteh, a Black Doves executive Netflix describes as having suspicious motivations. Ambika Mod plays Laila, an anarchic Black Doves agent sent to help Helen on a mission. In a season where the organisation may be turning on Helen’s own handler, a helper it assigns her is someone whose loyalty the story has every reason to test.

Ambika Mod, Neve Campbell and the new faces

The rest of the newcomers arrive with their roles kept quiet. Neve Campbell plays Cecile Mason. Sylvia Hoeks and Goran Kostic play Katia and Alexi Chernov, and Samuel Barnett plays Jerry. Netflix has not said whose side any of them are on.

The casting still says something about where the show wants to sit. Mod led Netflix’s One Day and broke through in This Is Going to Hurt, and her dry timing suits a series that has always let its killers bicker between jobs. Campbell is best known for Scream and The Lincoln Lawyer. Riley played Ian Curtis in Control. Hoeks was the replicant Luv in Blade Runner 2049.

Around them, the regulars return. Andrew Buchan is back as Wallace, Kathryn Hunter as Lenny Lines and Ella Lily Hyland as Williams, with Gabrielle Creevy, Agnes O’Casey and Molly Chesworth reprising their roles.

Joe Barton’s London

Barton has form with this city. Giri/Haji, his crime series for the BBC that Netflix took worldwide, sent a Tokyo detective into London’s underworld to find his brother. The Lazarus Project, for Sky, built a thriller around a secret organisation that answers to no government. Black Doves joins those two instincts: genre violence in streets the audience recognises, and an institution whose loyalty is for sale.

Julian Farino and Kieron Hawkes direct the new episodes. Knightley is also an executive producer, alongside Barton, Chris Fry and Jane Featherstone, whose company Sister makes the series with Noisy Bear. Netflix showed its hand early. It ordered a second season before the first had even premiered, and that first season, a Christmas-set thriller in London, went straight into the platform’s weekly Top 10.

What the synopsis leaves open is the question the series has been circling from the start. Helen’s secrets were always worth money. If Wallace reaches Downing Street, they are worth a government, and the organisation buying them is, by Netflix’s own account of this season, fighting itself. How long can a woman keep selling from inside a prime minister’s house, and who in the Black Doves would rather she stopped?

Black Doves season 2: release date, episodes, cast and where to watch

Black Doves season 2 premieres on Netflix on Thursday, November 5, with all six hour-long episodes released at once. The date is Bonfire Night in the UK, when Britain marks the foiled Gunpowder Plot of 1605 against Parliament, an apt slot for a series about a mole inside the political class. The first season, also six episodes, is already on the platform.

Black Doves is an original drama created by Joe Barton, not a true story. Keira Knightley, Ben Whishaw, Sarah Lancashire and Andrew Buchan lead the returning cast, and Ambika Mod, Babou Ceesay, Sam Riley, Neve Campbell, Sylvia Hoeks, Goran Kostic and Samuel Barnett join them. The official trailer is out on Netflix’s YouTube channel.
