Sometimes she drew.
Sometimes she sat quietly while her mother read.
The three knocks continued.
Even when Karl no longer seemed able to hear them, Emma knocked three times before entering.
It was part of how she said hello.
One evening, Matthias found her sitting beside the bed, looking at her grandfather’s hand.
Karl’s fingers rested loosely against hers.
“What are you thinking about?” he asked.
Emma looked up.
“His chalk.”
Matthias sat down.
“What about it?”
“He used to be scared he’d forget where my room was.”
“Yes.”
Emma looked at Karl.
“Do you think he’s still scared?”
Matthias considered his answer carefully.
“I don’t know exactly what Grandpa feels now. But we’re doing everything we can to keep him comfortable.”
Emma nodded.
She looked at his face.
Then she turned back to her father.
“Can you tell him I’m here?”
Matthias smiled.
“You can tell him.”
Emma leaned forward.
“Grandpa, it’s Emma.”
There was no answer.
She continued.
“I’m right here.”
Matthias placed a hand on her shoulder.
For several minutes, they sat together.
Then Emma looked down at Karl’s fingers.
Her own hand was small enough to fit inside his.
She remembered how those fingers had once held pencils, rulers, and pieces of chalk.
They had drawn houses, bridges, and imaginary towns.
They had pointed toward the river and traced routes across maps.
Now they rested quietly against her palm.
Emma held them carefully.
She looked toward the door.
Beyond it lay the hallway where the white line had once been.
The floor was clean.
The boards had been repaired.
There was no chalk left to follow.
But Emma knew the route.
She knew the turn past the landing window.
She knew where the corridor narrowed near the bookcase.
She knew which door belonged to her grandfather.
And she knew that whenever she entered, she would find someone who had spent years teaching her how to draw a line from one place to another.
She leaned closer.
“Grandpa?”
His eyes remained closed.
She smiled gently.
“You don’t have to remember the way anymore.”
Matthias lowered his eyes.
Emma rested her cheek against the pillow.
“I remember it.”
Her grandfather’s hand remained in hers.
She stayed until Anna came to take her to bed.
Then she carefully released his fingers, kissed his forehead, and climbed down from the chair.
At the doorway, she turned.
“Goodnight, Grandpa.”
The room remained quiet.
Emma switched off the small reading lamp beside her chair.
Then she walked back along the hallway to her own bedroom.
She did not need a chalk line.
She knew the way.
Years later, when Emma was old enough to understand more fully what had happened to her grandfather, she would find the old drawings in a box beneath her bed.
There would be the whale-shaped library, the little railway station, and the castle with no doors.
There would be sketches of bridges, houses, staircases, and rooms with windows that did not quite line up.
Among them would be a drawing made when she was six.
Two bedrooms.
A hallway.
A white line connecting them.
She would remember the arguments about the damaged floor, her grandfather’s embarrassment, and the frightened expression he wore when he could not explain what he had been doing.
She would also remember the tenderness with which he used to knock on her door.
Three times.
Always three.
She would come to understand that the chalk had never been a reliable solution to his illness.
It had been an attempt by a frightened man to make an increasingly unfamiliar world behave according to principles he had understood throughout his life.
A line could show the edge of a wall.
A line could mark the route across a bridge.
A line could connect one room to another.
For Karl, who had spent decades helping people find their way through buildings, drawing a line was the most familiar response he had to the terrifying experience of becoming lost.
Emma would remember that he had not been able to stop the changes in his memory.
Neither could she.
But she would also remember the afternoons when they built crooked castles, the smell of warm pretzels beside the Elbe, the goodnight stories, and the day he called her name while examining the bridge she had made.
Those things remained.
One day, long after she had stopped carrying stuffed animals to bed, Emma would visit the old house in Dresden.
The walls would have been repainted.
The furniture would have changed.
Karl’s drafting table might no longer stand beside the window.
But she would remember where it had been.
She would walk along the upstairs corridor and stop outside the bedroom that had once belonged to her grandfather.
For a moment, she would look down at the floor.
There would be no white marks.
No powder caught between the boards.
No evidence that an old man had once knelt there night after night, trying to make certain he could find a little girl’s room.
Emma would smile.
Then she would raise her hand and knock three times.
Not because she expected an answer.
But because some things deserved to be remembered in the same ordinary way they had been lived.
