Hugh Whitemore’s Breaking the Code is built around one of the great contradictions of the twentieth century: Alan Turing helped change the course of history, yet was punished by the very society that benefited from his genius.
Presented by Melville Theatre Company and directed by Barry Park, Breaking the Code is based on Andrew Hodges’ biography Alan Turing: The Enigma. It is a biographical drama about genius, secrecy, sexuality, punishment and the moral contradictions of mid-twentieth-century Britain. It is also a play about codes in more than one sense: wartime codes, mathematical codes, legal codes, social codes, and the private codes by which people try to survive.
At its centre is Thomas Dimmick as Alan Turing. It is a demanding role, and Dimmick carries a large share of the evening. Turing is rarely absent from the action, and the performance requires stamina as well as emotional and intellectual precision. Dimmick gives the role a thoughtful intelligence, holding together the contradictions of a brilliant, awkward, playful, stubborn and vulnerable man.
What gives the story its continuing force is that Turing was not only a victim of legal and social cruelty. He was also a mind looking far beyond his own age. His work helped lay the foundations for modern computing, and his thinking around machine intelligence now feels strikingly prophetic. In an era where artificial intelligence is no longer theoretical but part of daily life, the play’s glimpses of Turing as the man who helped imagine the “electronic brain” are among its most intriguing moments.
The production is strongest when it allows us to see that larger figure: not only the man who helped break Enigma, but a kind of national superhero, now recognised with his image on the British £50 note. The cruelty of his treatment lands most strongly when set against the scale of what he gave, and the scale of what his country failed to honour in his own lifetime.
The supporting cast bring considerable strength to the production. Patrick Downes diligently inhabits Detective Mick Ross, giving him the firmness of a man of the law as he conducts several interrogations of Turing. Anna Head successfully represents the motherly perspective of the 1940s and 1950s as Sara Turing, loving her son while remaining unaware of his sexuality. Jack Riches plays the mildly scheming and villainous Ron Miller, the low-level thief and lover whose actions help set Turing’s downfall in motion.
Grace Edwards brings warmth and clarity to Pat Green, giving insight into Turing’s wartime years and accurately portraying a relationship in which his homosexuality is accepted rather than condemned. Martin Forsey portrays Turing’s wartime boss, Dillwyn Knox, with strength and empathy, with many of their scenes providing thoughtful debate around social codes, judgement and compassion. Rounding out the ensemble, Nicholas Mountain, Nate Tonkin and Jamie Brooker ably help fill out the emotional and social world around Turing.
Barry Park’s direction treats the material with seriousness and respect. Mark Nicholson’s lighting and the simple, functional staging support the shifting locations, while Merri Ford’s costuming helps anchor the period. This is a sincere and committed community theatre production, led by a strong central performance and a clear respect for the man at the heart of the story.
When Breaking the Code was first staged in 1986, it was undoubtedly working to break taboos. Its treatment of homosexuality, state persecution and moral hypocrisy would have carried a sharper social charge in the era in which it was written. In 2026, those injustices are no less appalling, but they are less likely to shock an audience in quite the same way. For that reason, the play is most effective when it moves beyond the fact of persecution and into the more complicated territory of Turing’s mind, isolation, contradictions and historical significance.
Turing emerges as a man who broke codes for his country, imagined the future for the world, and was constrained by the moral codes of his own society. Melville Theatre Company’s production gives that story a thoughtful and respectful staging, with a committed cast and a strong sense of care for the remarkable life at its centre.
