But his personal physician refused to treat the problem as a minor misunderstanding.
"Someone may have attempted to interfere with what you were drinking."
The billionaire frowned.
"We don't know that."
"Correct."
The doctor nodded.
"Which is why the testing and investigation matter."
The chairman looked toward the window.
For a moment, he seemed irritated.
Then asked.
"Do you think the waitress was telling the truth?"
The doctor considered the question.
"I wasn't there."
He paused.
"But if the recovered material contains an unexpected substance, her warning deserves serious attention."
The billionaire remained silent.
Then his physician said something that unsettled him.
"If she hadn't interrupted, would you have drunk the entire serving?"
The chairman thought about it.
The antique bowl.
The matcha.
The quiet room.
And his mother's memory.
He nodded slowly.
"Yes."
For the first time, the question felt personal.
Not a business problem.
Not an embarrassing incident.
A question about whether he'd nearly consumed something dangerous because the people sitting beside him were people he believed he could trust.
His daughter arrived at the hospital that afternoon.
She was forty years old, elegant and composed, with shoulder-length dark hair and a practical navy suit. She had spent fifteen years working in environmental law and community land-rights advocacy, much of it in Japan.
Her relationship with her father had been strained for years.
She loved him.
But she was tired of arguing with him about the consequences of his company's expansion.
Their most recent disagreement concerned the Kameyama Ridge Development.
She believed the proposed agreement threatened water arrangements relied upon by small growers near Kyoto.
He believed she was allowing local opposition to obscure the project's economic benefits.
They hadn't spoken comfortably in months.
Now she entered the hospital room carrying a folder and an expression that frightened him more than he wanted to admit.
"Are you all right?"
The billionaire looked up.
"I'm fine."
She studied him.
"You were almost served a contaminated drink."
"We don't know what was in it."
She placed the folder beside his bed.
"Which is why you should be taking this seriously."
He sighed.
"I don't need another lecture."
His daughter stared.
For a moment, hurt passed across her face.
Then she took a breath.
"I'm not here to argue about the development."
He looked toward her.
"Then why bring a folder?"
She hesitated.
Then answered.
"Because the people who were sitting beside you at that dinner have been pushing the same agreement you asked me to examine."
The chairman's expression tightened.
She continued.
"I think the project and what happened at the restaurant may be connected."
He stared at her.
For several seconds, he said nothing.
Then asked.
"What makes you think that?"
She opened the folder.
