The word hung in the room like a blade.
"Open."
Anna's face drained of what little colour fear had left in it.
The boy backed into the wall.
The girl began coughing again — a dry, small, frightening sound, as if her body had not yet decided whether to become properly ill or simply surrender.
The man on the floor tried once more to rise.
Richard crossed the room in two fast steps and shoved him back down with the flat of his forearm, careful not to touch skin if he could help it.
The man wheezed in shock.
Good.
Shock was quieter than panic.
Another knock.
Harder.
The front door rattled in its frame.
A second voice called from outside, lower than the first and more impatient.
Richard understood more of it now than he wanted to.
Something about witness.
Light.
Stranger.
Anna looked at him with the expression people reserve for the final second before decision becomes fate.
Not What do we do?
Worse.
What will you do?
Richard's mind moved at once.
Problem set:
A sick household.
A suspected outsider.
A frightened woman.
A hidden device.
A language bridge only half-built.
Unknown authority at the door.
There were no good options.
Only rankings of disaster.
He took out the wrapped phone and typed under the cover of his coat.
RICHARD:
Likely authority type?
The response came quickly.
DESCARTES:
Municipal watch, local retainers, or household men acting under neighbourhood complaint.
Then another line.
DESCARTES:
Your highest-probability threat is not arrest. It is classification.
Richard stared at that for half a second.
RICHARD:
Classification as what?
The answer appeared immediately.
DESCARTES:
Thief. Heretic. Madman. Sorcerer. Plague-bearer.
Richard's jaw tightened.
Of the four, only one mattered immediately.
Plague-bearer.
In this century, that could become all the others very quickly.
Another knock.
"Open!"
The husband made a strangled sound and pointed weakly towards the front of the house, muttering a word Richard now almost understood.
Guard.
Richard looked at Anna.
He pointed at the children, then at the rear of the room, then at the pallet.
"Back. Quiet."
His pronunciation was clumsy, but close enough.
She understood.
Good.
He pointed at the husband.
"Lie."
The man glared at him.
Richard pointed at the swollen neck.
Then mimed coughing.
Then pointed at the door.
Then drew a finger hard across his throat.
You show this, you die.
That, at least, needed no translation.
The man went still.
Richard turned back to Anna.
The plan formed in brutal fragments.
Not truth.
Truth was useless.
He needed a version of reality primitive enough to be believed and structured enough to hold.
He pointed at himself.
Then towards the rear yard.
Then at the family.
Then spread his hands outward.
Traveller. Shelter. Nothing more.
Not healer.
Not authority.
Not miracle.
Not yet.
Anna stared.
He repeated it, slower, mixing words and gesture.
"Rain. Lost. Yard."
Then he pointed to her.
"House. Child. Husband."
Then shook his head sharply and held his palm up before his chest.
No mention of the phone. No mention of strange light. No mention of anything impossible.
Just a desperate man who had entered by the back during the rain.
Plausible.
Barely.
But medieval plausibility had more room in it than modern fact.
The knocking came again, now accompanied by the scrape of wood as someone tested the front latch directly.
Richard's heart thudded once, hard enough to make his vision tighten.
He typed again.
RICHARD:
Best immediate social posture?
DESCARTES:
Submissive without collapse. Useful without challenge. Dirty, tired, apologetic.
Then a second line.
DESCARTES:
Do not appear fearless. Fear is historically appropriate.
Richard almost smiled.
That was the coldest coaching he had ever received.
And the best.
He shoved the phone deep into the folds of the stolen wool cloak and pulled the rough cloth tighter around it until even the faintest leak of light disappeared.
Then, with quick efficient movements, he smeared ash from the hearth across the cleanest parts of his hands. A little on the jaw. A little at the neck. He raked damp fingers through his hair and bent his posture slightly, just enough to lose the modern uprightness Descartes had already condemned.
There.
Less impossible.
Still wrong. But less wrong.
He looked around for anything else that might betray him.
His trainers.
Too late.
No solution.
Not now.
Another shout from outside.
The second voice again. Harsher. Tired. Angry in the way men become when weather and duty cooperate badly.
Anna was trembling.
Richard stepped close enough for her to hear and spoke in the simplest words he had.
"You open. I stay back."
Then he pointed towards the boiling pot.
"Say — husband. Sick."
He pointed to the children.
"Fear."
Then he touched his own chest.
"Traveller."
Anna licked dry lips and nodded once.
That single nod meant trust.
Or desperation.
In crisis the difference was often cosmetic.
She moved towards the front of the house.
Richard stayed near the hearth, half in shadow, shoulders lowered, hands visible. Not too visible. He needed to look poor enough to be harmless and tired enough to be forgettable.
The front latch lifted.
The door opened.
Cold night air entered first.
Then two men.
One carried a lantern. The other a cudgel and a short knife at his belt. Neither wore anything like a formal uniform, but both had the unmistakable shape of local authority: men accustomed to entering weaker people's houses with questions already sharpened into accusations.
The lantern light swept the room.
It found Anna.
The children.
The husband on the floor.
Then Richard.
The man with the lantern stopped.
His eyes narrowed.
He said something fast to Anna. Richard caught perhaps one word in four.
Woman. Boy. Light. Stranger.
Anna answered too quickly.
Too defensively.
Mistake.
The cudgel-man took one step forward.
Richard lowered his gaze at once.
Not fully.
Too much submission could look theatrical.
Just enough.
The lantern-man spoke directly to him.
The sentence came like broken masonry, chunks of sound rather than meaning.
But Richard understood the structure.
Who are you?
He lifted his hands slightly, palms open.
"Traveller," he said, in the roughest local form he could manage. "Rain. Lost. Yard."
The men exchanged a glance.
Good.
That had at least entered the category of comprehensible speech.
The cudgel-man asked another question.
Faster.
Richard caught the final word.
Name.
He hesitated for the smallest fraction of a second.
Not because he meant to lie.
Because he suddenly understood that names, here, had class and geography inside them.
He could not be Richard Neitzmann, not cleanly, not yet.
Too foreign in the wrong way.
Too educated in shape.
So he did the simplest thing possible.
"Richard," he said.
Then, after the briefest pause: "Ricard."
The cudgel-man repeated it with suspicion, as if testing whether the name itself might confess.
"Ricard."
Close enough.
Then the lantern-man pointed at the husband.
A question.
Richard understood enough.
What happened to him?
Anna began answering, words tumbling over each other in fear.
Husband. Fever. Fall. Neck.
The men took one involuntary step back when she said fever.
There it was.
Fear had entered the room and chosen its true object.
Not Richard.
Disease.
Richard saw the shift and acted immediately.
He pointed at the husband's neck, then at the children, then sharply separated his hands.
"Bad sickness," he said in broken local speech. "No near. No touch."
The cudgel-man stared at him.
The lantern-man said something low and sharp.
Not approval.
But not dismissal either.
Richard realised, in that instant, that the single most important thing he possessed was not future knowledge.
It was clarity under pressure.
Most men in crisis either spoke too much or too little.
He was doing neither.
He was giving structure.
The cudgel-man pointed suspiciously at Richard's shoes.
Of course.
Modern trainers in a medieval hut.
Anna made a small sound.
Richard's mind moved faster than fear.
He lifted one foot, looked at it himself, and gave a grimace of shared embarrassment.
"Bad road," he said, then pointed vaguely outward. "Merchant dead."
That last word came to him almost by accident — some half-formed bridge of language, some guess built on context and rhythm.
But it landed.
The men's expressions changed.
Not softened.
Reorganised.
Dead merchant implied scavenging.
Scavenging implied poverty.
Poverty was legible.
Poverty made people normal.
The lantern-man spoke again, slower this time, and pointed first to Richard, then to the rear door.
As if asking whether he had entered by the yard.
Richard nodded at once.
"Yes. Yard. Rain."
Anna, to her credit, nodded too.
Good woman, Richard thought wildly. Very good woman.
The husband coughed again — a brutal, tearing sound — and the lantern-man recoiled a second time. The cudgel-man swore and covered his mouth with the back of his sleeve.
Fear was doing the work now.
Richard pressed it gently.
Not too much.
Too much and they might decide to burn the house.
He pointed to the boiling water.
Then to the husband.
Then at the men, and shook his head.
"No near."
The lantern-man's eyes narrowed.
He pointed to Richard.
Then to the pot.
Then to the husband.
Meaning: you are going near.
Why?
Reasonable question.
The room tightened.
Richard could feel Anna watching him with naked dependence. The children too. Even the sick man had stopped fighting long enough to listen.
This was it.
His first public line.
Not a miracle.
Not a speech.
A sentence.
He chose the simplest truth available.
"I know fever."
Silence.
The men looked at him.
Richard forced himself not to elaborate.
Desperation always overexplained.
He let the sentence stand there alone, poor and dangerous.
The lantern-man stepped closer.
Too close.
Close enough that Richard could smell sour ale beneath the rain and wool.
The man studied his face.
Then, slowly, he made the sign of the cross.
Not towards himself.
Towards Richard.
A test.
Or a defence.
Richard felt every muscle in his body prepare for the wrong move.
Do not flinch.
Do not smile.
Do not look offended.
Do not look amused.
Do not look innocent.
He lowered his head once.
Not in worship.
Not in fear.
Just acknowledgement.
The move seemed to satisfy something.
The man spoke again.
Richard understood almost all of it.
Not because the words had become simple.
Because the adaptation had crossed some invisible threshold.
"If you know fever," the lantern-man said slowly, "then keep them from the street."
Richard's pulse jumped.
He understood him.
Fully.
Or almost fully.
The world had shifted again.
The cudgel-man muttered something about morning. Priest. Reeve. Witness. Richard caught enough to know what it meant.
This was not over.
It was postponed.
Which, for the moment, was indistinguishable from mercy.
The two men backed towards the door, unwilling to come further into a fever-house. The lantern-man stopped on the threshold and looked once more at Richard.
"Ricard," he said, making the name sound like a temporary legal category rather than a person.
Then he pointed two fingers at his own eyes.
Then at Richard.
Watching.
He left.
The door shut.
The house did not move for a full three seconds.
Then Anna began crying soundlessly.
The boy slid down the wall and sat on the floor.
The girl swayed where she stood.
Richard turned towards her just as her knees folded beneath her.
He caught himself moving too late.
She hit the packed earth hard and did not get up.
Anna made a noise Richard never wanted to hear again.
Not a scream.
A mother's sound.
The one made when fear becomes arithmetic.
Richard crossed the room and dropped to one knee beside the child, stopping short of touch.
Her skin was burning.
Her breathing too fast.
The swelling at the throat now unmistakable.
His phone vibrated once.
He did not need to look.
He already knew Descartes had seen it too.
But he looked anyway.
One line.
DESCARTES:
Relevance threshold exceeded.
Richard stared at the words.
Then at the child on the floor.
Then back at the pot beginning to boil.
The watch had left.
The family had accepted him.
The girl was now collapsing openly.
And for the first time since arriving in 1347, Richard understood something terrible and exhilarating.
He no longer had the option of being a bystander.
