The Paradol Chamber

September 1907, Bern, Switzerland — Institut Fédéral de la Propriété Intellectuelle

The man who sat across from the patent examiner looked wrong somehow. Not obviously so—his suit was well-tailored, his posture upright, his hands folded neatly in his lap. But there was something about him that made your eyes want to slide away, as if focusing on him required effort the brain wasn’t willing to expend. He seemed fuzzy around the edges. Indistinct. As though he existed slightly out of phase with the rest of the world.

The examiner—a young man with unruly dark hair and eyes that suggested a mind perpetually occupied with problems more interesting than patent applications—rubbed his temples in frustration.

“I am only meeting with you again to get you to quit bothering me,” he said in English, his German accent thick but his words precise. “What more do you want?”

The fuzzy man leaned forward, and for a moment his features sharpened into focus. Intelligent eyes. Sharp cheekbones. A face that might have been handsome if not for the strain visible in every line, as if maintaining physical presence required constant concentration.

“I have been waiting for days,” the man said, his voice wavering slightly, like a radio signal fading in and out. “And all you can say is ‘your claim is incorrectly, imprecisely and unclearly prepared.’ I want to know exactly what is wrong with any of my ninety-nine ways to kill a cat.”

The examiner stared at him in disbelief. “Ninety-nine ways? You submitted ninety-nine separate patent applications for methods of killing cats?”

“Methods of studying mortality,” the fuzzy man corrected. “Of exploring the boundary between life and death. Of observing the exact moment when one state becomes another.”

“They’re methods of killing cats,” the examiner repeated flatly. He shuffled through the papers on his desk, each one bearing the official rejection stamp. “And I’ll tell you what’s wrong with them. Some are so obvious that a child—or even someone not skilled in the art of killing—would discover them naturally. Others are simply stupid.”

The fuzzy man’s hands tightened on the arms of his chair. For a moment, he seemed to flicker, his outline becoming even less distinct.

“Stupid?” His voice took on an edge. “How dare you—”

“Like this one.” The examiner held up a page. “Terrifying cats by putting them in enclosed boxes and dropping them from tall buildings. Why even bother with the box? Just throw the cats off the building if that’s your goal.”

“You don’t understand.” The fuzzy man’s voice was rising now, his form stabilizing with his agitation. “The cats feel that they are falling. They try to flip upright, which puts them upside down in the box, so they flip again and again and again. The disorientation, the repeated attempts to correct, the gradual understanding that they cannot escape—it’s fascinating. If you don’t believe me, try taking a cat on one of these new fast elevators sometime.”

The examiner looked at him with something between disgust and pity. “And then there are others that are so obscure I cannot make sense of them at all.” He pulled out another application. “What about this one where the cat is put in your box again with a vial of poison and some… stuff you don’t even properly describe. And you claim the cat will ‘probably’ die in the next day, as if some kind of roll of the dice determines whether the cat lives or dies.”

The fuzzy man stood abruptly, slamming his hands on the desk. His form solidified completely for the first time, and the examiner saw him clearly: a face that combined intelligence with something darker, an obsession that bordered on madness.

“But it works!” the man shouted. “As have all of these! I dare you to try any of them! I dare you to build the boxes, to set the conditions, to observe the exact moment of transition from alive to dead! You sit here in your comfortable office, processing applications you don’t understand, rejecting innovations that are decades—centuries—ahead of your comprehension!”

The examiner stood as well, his own anger rising. “This is a waste of my time. The London patent office rejected these inventions, and I agree with them. Get out of my office. I don’t want to see you back here again.”

The fuzzy man stepped toward him, something threatening in his posture. The examiner tensed, preparing to call for help.

The door opened.

A young assistant entered, papers in hand, and stopped short at the scene before him. The fuzzy man froze, his form beginning to waver again. He looked at the examiner with an expression that mixed rage and something like disappointment.

“We will meet again,” he said quietly. “When you understand. When everyone understands what I’ve discovered. When the world finally celebrates my genius.”

He turned and walked out of the office, his outline becoming less distinct with each step.

The assistant moved to the window, watching as the strange visitor descended the stairs out of the building to the busy street below.

“Sir, who was—” The assistant stopped, pointing. “Where did he go?”

The examiner joined him at the window. The street below was visible, people going about their business in the afternoon sun. But the fuzzy man was nowhere to be seen. As they watched, something impossible happened. In the space where the man should have been walking, the air seemed to vibrate. Shimmer. And then, for just a moment, a figure appeared—no longer fuzzy but sharp and clear and somehow wrong, as if he existed in too many places at once, as if all his possible positions were somehow overlapping into a single probability cloud.

Then he vanished.

Simply ceased to exist.

The assistant turned to the examiner, his face pale. “Mein Gott, was that…?”

“I don’t know what that was.” The examiner returned to his desk, gathering up the rejected patent applications. “Some crackpot from London obsessed with killing cats. Probably escaped from an asylum.”

“But he disappeared, Mr. Einstein! He vanished into thin air!”

Albert Einstein looked at his assistant with the patient expression of a man who dealt with impossible things every day in his mind, even if they rarely manifested in reality.

“Then I suggest we both forget we saw it,” he said firmly. “Some things are better left unexplained. File these rejections and let’s speak no more of the matter. I have more important things to think about!”

But as his assistant left the office, Einstein found himself staring at one of the applications. The one with the box, the poison, the probability of death.

The cat that was both alive and dead until the box was opened and the cat observed.

It was nonsense, of course. Impossible. No object, much less a living one, could exist in two states simultaneously.

And yet, Einstein placed the application in his desk drawer rather than the rejection file. Just in case.

Somewhere in time, in a moment that was both past and future, a man named Sherrinford Holmes smiled.

The seed had been planted.

Now he just had to wait for it to grow.

London, England — Present Day

The conference room at 10 Downing Street smelled of old wood polish and newer anxieties. Four men sat around the mahogany table, each wearing suits tailored to suggest competence and power, though Mycroft Holmes knew better.

He’d been deducing their current weaknesses since the moment they’d sat down, a habit he found simultaneously useful and tedious.

More than a century had passed since a strange man had tried to patent methods of killing cats in a Swiss patent office. Einstein had died, his theories vindicated and expanded upon, quantum mechanics had become established science, and the world had moved on. But some obsessions, some seeds planted, like quantum states themselves, never truly collapsed. They waited in superposition, simultaneously alive and dead, until the moment of observation.

And in London, on a grey November afternoon, that moment was about to arrive.

Mycroft Holmes checked his mobile phone for the third time in as many minutes, waiting for a text from his brother that would either confirm or deny a bet they’d made about a woman’s ancestry.

He had no idea that the game he was playing had rules written at the creation of the universe, and that had been put in play in ways that would affect him more than a hundred years ago.

And that somewhere in the city, someone was preparing to open a box that should have remained closed.

Had no idea that the past and future were about to collide in ways that even his formidable intellect couldn’t predict.

“And now we come to the Syrian rebels—” Official #1 began, consulting his notes with the air of a man who believed reading from a document constituted actual thought.

“One hundred fifty million,” Mycroft interrupted, his voice smooth as aged whiskey. He didn’t look up from his mobile phone, which sat before him on the table like a silent familiar. No messages. Still.

Official #2 blinked. “What’s that?”

“Pounds sterling pledged by the Prime Minister in support of the rebels.” Mycroft’s nose twitched almost imperceptibly. The man to his left was perspiring despite the room’s careful climate control. Nauseous. The faint scent of partially digested curry lingered. Binge eating again—the man’s trouser button had been replaced recently, moved outward by at least two centimetres.

“Have you discussed this with the Prime Minister?” Official #1 asked, a note of challenge creeping into his bureaucratic drone.

Mycroft finally lifted his gaze, allowing himself the smallest of smiles. “I will. Make a note of the amount…and do be accurate for accounting.” He glanced at his phone again. Nothing. His younger brother was being unusually reticent. “Do try to control your dietary habits before the budgetary committee meeting, won’t you? The Prime Minister has little patience for fiscal irresponsibility, whether governmental or personal.”

Official #1’s face coloured slightly, but he said nothing.

They never did.

“ISIS has, yet again, built up a small army near the Zagros Mountains—” Official #3 ventured, attempting to reclaim control of the meeting’s agenda.

Mycroft raised an eyebrow as he catalogued the man’s tells: the slight cant to his wedding ring (worn at work but removed elsewhere), the particular cologne (expensive, but applied in the afternoon rather than morning—after a lunch that hadn’t involved his wife), the faint lipstick trace on his collar that absolutely did not match Mrs. Official #3’s preferred shade of coral.

“—guns, artillery, and that’s it,” Mycroft completed the thought. “We don’t want any of our advisers over there this time. Let the Americans handle it.”

“You mean the CIA? Isn’t that what you mean?” Official #2 pressed, as if catching Mycroft in some verbal trap.

The man was new to these meetings, still believed in the fiction that euphemism and careful language could somehow obscure reality from men who dealt in reality’s darkest corners. Mycroft noted the too-square fit of the man’s shoulders in his jacket—former military, attempting to squeeze back into civilian frameworks that no longer quite fit.

“I mean what I say,” Mycroft replied evenly. “Does the CIA know this yet?”

“They will.”

Officials #1 and #3 mouthed the words along with him, a synchronised chorus of familiarity that might have been amusing if it weren’t so predictable. Mycroft drummed his fingers once—twice—against the mahogany, then caught himself. Fidgeting was beneath him. But where was Sherlock’s text? His mobile remained dark and silent.

“There is the matter of Nigerian resistance—” Official #3 began.

“—not on the table at this time,” Mycroft cut him off, “nor is North Korea, Ukraine, or the World Cup finals.”

“I’ve got money riding on that,” Official #3 protested weakly.

Mycroft allowed himself a thin smile. “Whatever it is, it’s too much. Your mistress won’t approve.”

A beat of shocked silence, then nervous laughter rippled around the table. Everyone except Mycroft. He checked his watch—an Omega Seamaster, inherited from his father, accurate to within 0.07 seconds per day—and noted with satisfaction that Anthea’s timing remained impeccable.

The door opened, and his assistant entered, her mobile already in hand, fingers flying across the screen in the perpetual dance of the professionally indispensable. “That’s all, gentlemen, thank you,” Anthea announced without looking up. “Same time and place two weeks from now. Thank you.”

The officials filed out with the relieved shuffle of men granted parole from a particularly demanding warden. Anthea’s texting never paused, the soft tapping of her thumbs against glass a counterpoint to the officials’ retreating footsteps. “He hasn’t—” Mycroft began.

His mobile buzzed.

Mycroft snatched the phone up with unseemly haste, a small smile tugging at his lips as he read the message. Four words: Not Latvian. You win.

“Are you the Cheshire Cat?” Anthea asked, the ghost of amusement in her voice.

Mycroft’s smile broadened infinitesimally. “I’ve answered to that, yes. Car.”

“Car,” Anthea confirmed, though whether to him or into her phone was unclear. She swept from the room, still typing.

Mycroft stood, pocketing his mobile with the satisfaction of a man who’d just won a small but significant victory. He adjusted his tie—a subtle Windsor knot in navy silk—and allowed himself a moment of fraternal triumph. It wasn’t often he bested Sherlock in their ongoing game of deductions, and when he did, the prize was always worthwhile.

Today’s stakes: fish and chips from one of the few establishments in London still willing to fry their cod in beef drippings as God and tradition intended. Greasy, excessive, perfectly unhealthy—everything his carefully maintained diet, and his public and self image, forbade.

Which made victory all the sweeter.
