Viewers couldn't agree on the new drama inspired by Tom Bradby's novel

ITV's spy thriller debuted on screens on Monday night, but unfortunately left viewers split down the middle in their assessments of the show, which is based off newsreader Tom Brady's novel of the same name.

The drama follows senior MI6 officer Kate Henderson (Gemma Arterton). On the surface, her life appears ordinary: a civil servant married to Stuart (Rafe Spall) with two teenage children.


However, behind that facade, Kate heads the Russia Desk at the Secret Intelligence Service.

When her undercover operations reveal alarming evidence that a high-ranking UK politician may be working as a Russian asset, Kate finds herself in a desperate race to identify the traitor.

Speaking recently to GB News and other media, journalist Mr Bradby detailed insights into bringing his spy thriller to screens. insights into bringing his spy thriller to screens.

Mr Bradby, who serves as both ITV broadcaster and creator of the source material, conceived the story amid growing concerns about Russian interference in Western democracies.

"I just thought, 'Well, imagine if you were actually what would that really be like? How would your bosses react? How would the politicians react?'" he reflected.

He acknowledged that adapting the novel for television required the story to develop alongside shifting global circumstances.

"Obviously it did have to evolve, because the world was evolving," he said. "But as I said, the slightly scary thing is, it never felt any less relevant."

Originally penned seven years ago, the tale has only grown more pertinent with time, something Mr Bradby views with mixed feelings.

"It just seems to get more and more relevant, which is great for the drama, but possibly not for democratic societies," he noted.
