“What research?”
“The Triad Model.”
I hadn't heard someone other than Michael or Professor Park say those words in years.
“How does he know about that?”
Nathan looked toward the glass building.
“Because Hartley Adaptive Learning is built on it.”
I laughed reflexively.
Not because it was funny.
Because sometimes the brain produces laughter when reality arrives too fast.
“No.”
“Mom.”
“That work was incomplete.”
“So?”
“I never licensed it.”
“We know.”
“Michael’s company developed its own model.”
“No,” Noah said.
His voice was gentle.
“Dad says he developed it.”
The word
Dad
sounded unnatural coming from him.
He continued.
“Evan found archived source files on an old company server while working on a summer internship.”
“What kind of source files?”
Noah pulled out his phone.
He showed me a photograph.
My breath disappeared.
On the screen was a page covered in handwritten equations.
My handwriting.
I recognized the coffee stain in the corner.
I recognized the notation.
I recognized a stupid doodle of a turtle I used to draw when stuck on difficult proofs.
“That’s impossible.”
Nathan swiped.
Another photograph.
A draft dated sixteen years earlier.
LAURA HARTLEY.
TRIAD ERROR-RECOVERY MODEL.
Then another.
A typed memo.
The author line had been altered.
Michael Hartley.
My hands began shaking.
“No.”
Noah took the phone back.
“There’s more.”
“How much?”
“A lot.”
The boys told me Evan had found thousands of old documents while assisting with an internal archive migration.
He recognized Michael’s name.
Then mine.
Then dates.
Evan had grown up hearing a particular story.
That I had been jealous of Michael’s success.
That I had resented Rebecca.
That after the divorce, I had taken the twins away and refused contact.
I stared at my sons.
“He told you that?”
Nathan nodded.
