Gemma Arterton leads five-part Secret Service Itv spy drama
Gemma Arterton leads secret service itv as MI6 agent Kate Henderson in a five-part espionage drama adapted from Tom Bradby’s 2019 novel. The series puts family life, covert work and a British leadership contest into the same frame, with a cabinet member under suspicion after an undercover operation in Malta.
Kate Henderson and Malta
Kate Henderson and her undercover team infiltrate the Malta base of Russian oligarch Igor Borodin, then uncover a lead that a member of the cabinet may be a Russian asset. That gives the drama a political spine instead of a simple spy plot, and it keeps the action tied to a question that lands well beyond the field agent level: who inside government can still be trusted.
Tom Bradby and Jemma Kennedy adapted the series from Bradby’s 2019 novel, and that matters because the show arrives already carrying a built-in political frame. Gemma Arterton plays Henderson as an MI6 agent juggling family life with secret work, which is the series’ main emotional pressure point even before the Westminster plot fully opens up.
Leadership after the resignation
The resignation of the prime minister pushes the story into a leadership contest with two most likely candidates: home secretary Imogen Conrad and foreign secretary Ryan Walker. Steven Elder plays the departing prime minister, while Walker’s friendship with the Russian foreign minister and his flirtation with nationalism give the succession race a sharper edge than a standard internal party contest.
“The last thing we need is allegations of Russian collusion. We all know what happened in America” is the line that makes the show’s political ambition plain. The review also says there is no tension-puncturing banter or smartly veiled digs at the real-world government, so the series plays its cards straight instead of using satire as cover.
Guardian verdict on Secret Service
“Secret Service is not, in any conceivable way, fun.” That judgment is blunt, but it also draws a clean line around the drama’s strategy: this is a serious, unfunny espionage series, and even the saucier material is handled solemnly. Compared with the lighter register of some modern spy dramas, that approach narrows the audience it will please and signals a show more interested in pressure than wit.
For viewers, the practical takeaway is simple: Secret Service Itv is built around five parts, not a sprawling franchise, and its central hook is Kate Henderson’s investigation into Russian influence at the same moment Britain’s top political job opens up. If the series keeps the Malta trail, the cabinet suspicion and the leadership race in the same lane, it has enough moving pieces to justify the setup; if it does not, the solemn tone will have to carry the load alone.
