Known as one of the greatest espionage stories ever written, John le Carré’s The Spy Who Came in From the Cold tells the story of Alec Leamus – a British intelligence officer who takes on his final mission before returning home from duty.
At Wales Millennium Centre for this week only, the stage adaptation is by award-winning playwright and screenwriter, David Eldridge. Following its 2024 sold out premiere at Chichester Festival Theatre, the show brought high expectations, and it didn’t disappoint.
Starring British TV icon, Ralf Little (Two Pints of Lager, Royal Family), as lead role, the show focuses on true deception, secrecy and intrigue. Alec wishes to get out of the cold, but when presented with an offer he can’t refuse, he decides to stay in his position a little longer, but it comes with a price.

The stage adaptation is different to the book in many parts, but equally as enjoyable. As an audience, we see the stage shift between real life, Alec’s mind and his fantasies, using subtle lighting to flick between scenes. The performance certainly allowed for the audience to use their imagination when drifting between real life and delusion, as Alec battles with the truth versus where he’s been deceived. We see how his own lines get blurred during his final mission; unsure if he’s being played himself or if the British ‘circus’ have his back throughout the mission. Combined with the added weight of protecting his new love interest, Alec feels the weight on his shoulders as things begin to spiral.

Going into this show, you have to keep an open mind – there’s a lot to unfold and the timeline moves quickly. As scenes move fast, it’s a show where you need to focus to absorb the narrative, but it’s well worth grabbing all of your attention.
The show is everything you’d expect from a spy story – dark and inquisitive, finished with a plot twist.
The Spy Who Came In From The Cold is at Wales Millennium Centre until 2nd May 2026.
