I no longer imagine her sitting there.
I imagine her somewhere else entirely.
Young again.
Standing beside that prototype in 1991.
Sleeves rolled up.
Pencil behind one ear.
Arguing mathematics with the brilliant daughter-in-law who did not yet know she would one day surrender her own name.
I imagine Grandma looking toward a future she could not possibly see.
Toward Marisa.
Toward me.
Toward a granddaughter who would eventually build a system designed to uncover hidden instability.
A system that would expose the very secrets her family buried.
And I finally understand why, when I was sixteen and terrified I wasn’t talented enough to pursue mathematics seriously, Grandma looked at me across that old walnut desk and said something I thought was only encouragement.
Now I know it was a confession too.
She said:
“Sylvie, truth has a strange habit of waiting for the right woman to find it.”
Thirty years of secrets had been hidden inside companies, marriages, trusts, patents, bank accounts, lies, and one old wooden desk.
