Bletchley Park, 1954

Alan Turing is dead. Cyanide.
They call it suicide. I call it murder. Plain and simple. Cold-blooded murder.
A genius hounded, humiliated, stripped of work, stripped of dignity, and finally broken. Alan was only forty-one. One of the greatest mathematicians of our age destroyed by a pack of ignorant zealots.
And where is gratitude? If Alan hadn’t cracked Enigma, half the so-called pillars of society would be goose-stepping in jackboots today. The same people who dragged him into court two years ago for “gross indecency” and forced him into chemical castration—did they ever stop to think? If the Nazis had won, if the camps had multiplied, how long would they themselves have lasted?
By some cruel twist of fate, his punishment coincided almost to the week with my marriage to John.
“Congratulations, Joan. I hope you’ll be happy,” Alan said on the telephone, voice dry, brittle.
“I will, Alan. John is a good man.”
“Quite. And unlike me, not… unnatural.” His laugh is bitter, hollow.
“Don’t talk like that, Alan. Unnatural? Rubbish. It’s nature. Even animals do it—my biologist friend told me so.”
“Do you really not think I’m a pervert, Joan? A monster?”
He was asking for validation, his tormentors had destroyed his confidence. I could almost see him…sunken eyes, dark circles under them, dishevelled hair. I did my best to assure him.
“No. I think you’re a human being with your own reality. The perverts are the ones who judge you.”
“You should have married me then, Joan. At least I’d have had one person.” His brittle laugh again, like broken glass.
“We could have. I told you—I don’t care. Why did you break our engagement, Alan? How many couples have what we had? That bond of mind?”
“And the physical side, Joan? I could never… with a woman...”
“Then don’t. Is that all marriage is about? We did cryptanalysis together. Played chess. Knitted wool scarves. Worked on your Turing machine theory. We made each other laugh. We made each other happy.”
“I know, Joan. I miss you every day. But marriage is… more. You’d want children.”
“My work is my child, Alan. John and I may never have children. And even if we do—the only thing that lasts decades is the spiritual bond, the connection. That’s what endures.”
Alan was silent a long time. I pressed on.
“Has the farce of your trial ended?”
“Yes.”
“And?”
“Guilty. Chemical castration.”
“Barbaric! Why submit?”
“What choice do I have, Joan? The other option is to go to the prison. You know what that means? No work, no clearance afterwards. I couldn’t. This was… better.”
That day, I wasn’t speaking to one of the greatest mathematicians of our time. I was speaking to a broken man. A man eaten alive by prejudice.
Things are improving for me, after all. The war changed everything. Women are freer now. We no longer creep in the shadows. Cambridge grants degrees to women. Bletchley welcomes more of us. I’m Deputy Chief of Hut 8. But Alan—Alan is ground down.
“It was my mistake,” I whispered that day over the phone. “I should never have broken the engagement. I should have married you. We’d have protected each other.”
“Then it wouldn’t have been a marriage, Joan. It would have been a sham. A lie.”
“So what? People have sham marriages every day. Ours would at least have had purpose.”
“It’s too late, Joan. Be happy with John. He’s a cryptanalyst too—he can give you both mind and body. Don’t pity me.”
I did marry John, and I am—mostly—happy. We both work at Bletchley. The new household, the work—it consumed me. Alan retreated to Cheshire, and I rarely saw him. Until this news today.
They killed Alan Turing, inch by inch. Enough is enough. I won’t stay here either. John’s health is failing; he doesn’t want to remain. And I cannot forget. They drove Alan out, stripped his clearance, barred him from the very machines he helped build.
To hell with them. I finally cracked that cipher—the pink slip of paper he gave me the day he proposed. Captain Higgins told me later of the SS Minden and its cargo. For years I believed no one knew where that ship sank. But just last week, on holiday in Iceland, I stumbled on the location.
I thought to report it. But not now. Not after what they did to Alan. I’ll keep it hidden. Encoded. A legacy for those worthies to find it. I won’t spell it out in plain English. No. It will remain cipher. My tribute to Alan.
And perhaps—just perhaps—I’ll leave the locattions wrapped in riddle, hidden in verse. Not Enigma again—that’s too obvious. Something new. Something only a true mathematician, a true cryptanalyst, could break.
People say mathematics is dry. They are fools. Nothing is more beautiful. Pure. Elegant. Harmonious. Like poetry.
Yes—poetry. That will be the key. My cipher will be hidden in verse. If my heirs are clever enough, they will find it. If not—let it rest forever at the bottom of the sea.

Bletchley Park, 2024

“You got permission to access Joan Clarke’s house, Mirella?” Matt asks as the train hums north out of Euston. The four of us—Matt, Mirella, Sayak and I—are heading for Milton Keynes. First, the Enigma Museum at Bletchley. Then, Clarke’s home.
“Where exactly is the house?” Sayak asks.
“Milton Keynes,” Mirella answers crisply.
“And her family? Anyone still there?” Matt presses.
“She married John Murray after breaking off her engagement to Turing. But they never had children. The house was her family’s, passed down to nephews. The current owner is her grand-nephew—Arthur Clarke.”
“And you contacted him?” I ask.
“Yes. He was surprisingly enthusiastic. He said he’s tired of Hollywood melodrama—‘The Imitation Game’ is somewhat over dramatic. He wants something authentic.”
Sayak frowns. “That supposed romance between Turing and Joan—it’s absurd.”
“Absurd?” Matt cuts in.
“Yes. A gay man in love with a woman romantically, while seeking men sexually? It doesn’t work like that. Desire doesn’t split neatly in two.”
Mirella nods. “Arthur said the same. They were colleagues. Friends. Both outsiders in a brutal, conformist society. They understood one another. That bond didn’t need romance.”
We step off the train at Bletchley and follow the signs past the lake to the old Victorian mansion, its brick and terracotta glowing in a shy English sun. The huts sit low and plain around it—weatherboard, green-painted, practical as ever. Inside Hut 8 the air feels close, as if still warmed by concentration: scuffed lino, battered desks, pencils lined like bayonets, an Enigma machine under glass that seems to hum with withheld secrets. A Bombe clicks methodically in a dim room, its rotating drums like a heartbeat from 1941. I trace the names in the displays—Alan Turing’s neat scripts, Joan Clarke’s calm, incisive notes—and can almost hear the midnight rustle of paper, the murmur of chess problems traded over tea, the sudden shout when a crib lands and a convoy is spared. Outside, the grass is bright and ordinary; inside, every corridor is a fuse to memory—messages, methods, minds—quiet courage housed in timber and tin. Here, the war narrows to pencils, logic, and the stubborn grace of people who simply refused to let the Atlantic go dark.
We wander the huts, the bombes, the machines that saved millions. Hut 8—Joan’s hut—still feels charged. Women like her worked in silence, ignored in the history books. Mirella’s research aims to set that right, at least a part of it.
We finish our tour at the museum and head for our next destination, Joan Clarke’s old home. By the time we reach there, the afternoon light is long and golden. The house is solid, Victorian, a century and a half old at least.
A tall, dark-haired man in his thirties opens the door—broad jawline, striking features. Arthur Clarke. Inside, after introductions, Mirella gets straight to it.
“Arthur, thank you for seeing us. These are my colleagues. They share my interest in Joan Clarke.”
“Not at all. Since that film, many have come. Fewer these days, but still.” Arthur smiles.
“You think the cipher she left was real?” Matt asks.
Arthur shrugs. “Perhaps. All I know is that one scrap survived, a cipher text. I gave it to Mirella. She asked her friends to try.”
Mirella hands him the translated sheet.
Arthur scans it. “‘Scuttle the ship. From the Führer.’ Extraordinary. Why on earth?”
“Nazi naval orders,” Matt explains. “Direct from Hitler. Whatever the SS Minden carried, they preferred to sink it than let it be captured.”
“What was on board?”
“We don’t know yet. Our friend Sayak found records in the British Library: the Minden was intercepted in 1939 by HMS Calypso and HMS Dunedin. The order to scuttle came immediately after.”
Arthur leans back, eyes narrowing. “And no report from the Royal Navy?”
“Nothing public. Nothing declassified.” I add quietly.
“Strange. After eighty years, why still keep it buried?”
Matt pounces. “And why give this to Mirella? Why now?”
Arthur spreads his hands. “No great reason. She came asking questions about Joan. It jogged my memory. She worked on ciphers—so I showed her one. Simple curiosity.”
He ushers us into Joan’s study: a narrow, high-ceilinged room that smells faintly of old paper and lavender polish. A polished mahogany desk anchors the space, its leather blotter speckled with ink ghosts; beside it a Victorian brass angle-poise still works, green shade crazed with age. An orderly drift of artefacts remains where she left them—slide rule, fountain pen, a Bakelite telephone with a frayed cloth cord, an Underwood portable in its case. Along the walls, shelves bow under the weight of leather-bound files, their spines sun-faded and foxed, cotton ties knotted tight; cardboard wallets are labelled in a neat, slanted hand, margins alive with pencil ciphers and dates. Above the mantel hangs a faded Ordnance Survey map pricked with pins; on the windowsill, a small silver frame: two figures in wartime tweed, half-smiling. Dust motes turn lazily in the lamplight, and for a moment the room hums with the quiet, ferocious order of a mind that never quite stopped working.
“This was hers,” Arthur points to an array of leather bound old files.
I open one folder. Inside—typed memos, handwritten notes. And then—verse. Poetry.
“This isn’t maths,” I whisper. “It’s poetry.”
“Joan wrote poems,” Mirella says gently. “I’ve seen her notebooks.”
Arthur nods.
Sayak grins. “See, Sri? Programmers can write poetry.” He raises his phone. “Mind if I take a photo?”
“Not at all. Are you a programmer yourself?”
“Yes,” Sayak replies, smiling.
“And a poet too,” I add before he can protest.
Arthur laughs. “Then we must cultivate you, my friend.”
As Sayak snaps photos—angles, close-ups, a wide frame of the shoreline—Arthur hangs back, radiating easy charm. He’s all warm smiles and polished small talk, sleeves rolled just so, the kind of bloke who remembers everyone’s name within a minute and sprinkles in a joke at his own expense. Yet there’s a seam of caution under the gloss: the way his gaze skims past questions he doesn’t fancy, the half-second pause before he answers, the habit of turning queries back on the asker. He laughs readily, but his eyes don’t; they measure, file, move on.
When he mentions his charity—teaching coding to disadvantaged kids—it lands a little too neatly. The spiel is smooth, practised, the bullet-points lined up like ducks: impact, outreach, partnerships, success stories. It sounds fine, admirable even, but it also sounds like a grant application read from memory. Matt hears it too. He leans on the rail as if idly watching the tide, but his detective’s instinct never powers down. When Arthur breezes past a specific—where the classes run, which schools—they blur into “various centres” and “across the Buckinghamshire and Berkshire”. Matt doesn’t challenge him; he just files it away, a quiet red flag. Sayak lowers the camera, satisfied. Matt keeps looking. Arthur keeps smiling. The wind lifts, and something unspoken shifts with it.
We leave at dusk, minds buzzing, questions multiplying. Joan’s cipher, Alan’s ghost, the sunken ship—all tangled now.
And Arthur Clarke—handsome, helpful, but hiding something.
Very much hiding something.
