Chapter Text
Sherlock Holmes was four years and eight months old when he discovered that humiliation could fit inside eight letters.
This was not an ordinary humiliation. Not the humiliation of an impossible button, a chair too high, an adult smiling because a child had used a word too large for his mouth. Sherlock already knew those humiliations. They were mediocre, and therefore bearable.
This one came from a book.
The book belonged to Nell, or rather had come from Nell, which was different. Their grandmother sometimes sent objects the way other people sent postcards: without warning, without explanation, with far too much good taste and a perfect indifference to practical consequences. This one had arrived from France in a box that smelled of dust, dried lavender, and cupboards where entire centuries were shut away. Margaret, their mother, had said they had to be careful with the pages. Mycroft, almost twelve already, had said that insects were an acceptable subject provided none were introduced into the house. Eurus had only placed her hand on the cover.
The sitting room at Musgrave was grey that day. An ordinary English rain-grey, the kind of rain that did not need to fall hard to occupy everything. The windows were wet. The fire had not been lit because Margaret had decreed that it was not cold enough, which was false but economically defensible. The book lay on the carpet, open between Sherlock and Eurus.
It was very large.
Larger than necessary.
The insects were drawn with an almost unreal precision: mandibles, legs, carapaces, translucent wings, antennae so fine they looked ready to break under someone’s gaze. Beneath each image were names in French, in Latin, sometimes in German. Sherlock liked Latin names. They had the decency to be difficult without pretending to be anything else.
Eurus, however, could read French.
That was the problem.
She was three and a half, with chestnut hair tangled around her face, a pale blue dress already creased, and she was lying on her stomach in front of the book with the calm expression of someone who had just found a door already open. She followed the words with her finger. An ordinary adult might have thought she was pretending, but no: she was reading.
Sherlock refused to admit it with admirable bad faith.
“You’re reciting.”
“No.”
“You know the insects in the pictures.”
“Yes.”
“So you’re guessing.”
“No.”
She placed her finger under the word.
SCARABÉE.
“Scarabée,” she said.
Sherlock stared at the letters.
He knew some of them. The S. The A. The R. He knew the separate sounds. He even knew that the accent on the E changed something, because Margaret had said so the day before while talking about a French paper, and Sherlock did not forget that kind of information, even when it had been misfiled.
But the whole word resisted him.
Eurus knew it.
Unacceptable.
“You’ve heard it before,” he said.
“Yes.”
“So you’re repeating.”
“I’m reading.”
“Same thing.”
She turned very calm eyes on him.
“No. Repeating is taking someone else’s noise. Reading is opening the noise yourself.”
Sherlock said nothing.
Mycroft, in the armchair near the window, looked up from his book.
He was already too tall for his age, too straight, too carefully arranged inside a body that had not finished deciding whether it wanted to be a child. He observed the scene with the caution of a miniature diplomat.
“A contestable definition,” he said.
Eurus didn’t look at him.
“It’s true.”
“It is unnecessarily poetic.”
Sherlock hated that they could have a conversation above him when the whole problem was that he couldn’t read a word.
He pulled the book closer.
“I know the letters.”
“Yes,” Eurus said.
“So I know the word.”
“No.”
“I do.”
“You know the pieces. Not the word.”
She was not saying it to humiliate him.
That was worse.
She was stating a fact.
Sherlock looked at the drawing of the scarab. The black, shining carapace, the pale little line down the middle, the delicate legs. He would have preferred the insect to be ugly. There was something unfair about a difficult word under a beautiful creature.
Eurus said:
“You looked at the scarab because it’s shiny.”
“Yes.”
“The word does too.”
Sherlock frowned.
“A word doesn’t shine.”
“Yes, it does.”
She touched the letters, one by one.
“Not with light.”
He wanted to say that was absurd. But he almost understood. The word had a compact, dense, organised shape. It contained more than the separate letters. It held a truth Sherlock did not yet know how to read.
He said:
“Read it again.”
Eurus smiled.
“No.”
Sherlock stared at her.
“Why?”
“Because you want to take my noise.”
“I want to check.”
“No. You want to steal.”
Mycroft gently closed his book over one finger.
“Eurus.”
“What?”
“The accusation of cognitive theft may be excessive.”
“No.”
Sherlock bent over the word.
He broke it apart.
S. Ca. Ra. Bée.
No.
Sca. Rab. Ée.
No.
The C was behaving badly. The A was no help. The B seemed to arrive too late. The accent looked at him like a small French weapon.
Eurus waited.
It was almost polite. Therefore unbearable.
“You open it,” she said at last.
“What?”
“The word.”
“How?”
She placed her finger at the beginning, then slid it very slowly under the letters.
“You open it. Then you close it again.”
“That doesn’t mean anything.”
“Yes, it does.”
“Letters aren’t doors.”
“No. Letters make noise together. Not alone.”
“Letters do make noise on their own.”
“Yes. But that is just the alphabet. And the alphabet is a corridor, not a room.”
Mycroft went absolutely still.
Margaret, passing the doorway with a cup of black tea, stopped as well.
Sherlock felt that something had just happened around that sentence, but he refused to pay attention to it. He had a word to defeat.
“Again,” he said.
Eurus looked at him.
“Do you want to come?”
“Where?”
“Into the words.”
He immediately hated the phrasing.
It was beautiful.
Therefore suspicious.
“I already know how to read some words.”
“Not this one.”
“Not yet.”
She nodded.
“Not yet.”
He took a breath.
Looked at the letters.
Not the pieces.
The word.
The noise together.
He tried.
“Sca… rabée.”
“No.”
“Scarab…”
“No.”
“Scarabée.”
Eurus said nothing.
It was her way of admitting he had succeeded.
Sherlock raised his head.
“That’s it.”
“Yes.”
“You could have said so.”
“You knew.”
Sherlock did not know whether that was satisfying or intolerable.
Margaret finally came into the room.
“Is everything all right?”
“Sherlock has learned scarabée,” Eurus said.
“I already knew.”
“No.”
“Almost.”
Eurus placed her finger on the word again.
“You were in front of the door.”
“And now I’ve come in.”
Eurus looked at him for a long moment.
Then she said, with quiet gravity:
“You can come into the words. But you mustn’t break the doors.”
Margaret set down her cup.
Mycroft lowered his eyes.
Sherlock looked at the scarab again.
He had no intention of breaking the doors.
He intended to know how they worked, why they opened, what lay behind them, and who had decided that Eurus should have the key before him.
Which was, in his opinion, entirely different.
For now, he was four years and eight months old.
His sister was three and a half.
She read better than he did.
Unacceptable.
He pulled the book closer.
“Next page.”
Eurus smiled.
“Finally.”
