I owe Isabela a debt I can never quite repay, and I want it recorded here, because the story could so easily be told without her and it would be a lie.

When the truth came out on that plane, she had every incentive to help bury it.

Her family was as implicated as mine; the scandal would cost her as much; a more self-interested woman would have counseled patience, discretion, a quiet management of the situation that protected everyone’s name — which is to say, another cover-up on top of the first.

Instead she took off her ring in my father’s study and called what he had done by its true name, and then she went home and gathered three years of her own parents’ correspondence, the shell accounts, the payments, and she carried that binder to a police detective with her own hands, knowing exactly what it would do to her family.

She chose the truth over her name, which is the precise choice I had failed to make three years earlier, and she made it in a single evening without apparent effort, as though it were obvious, as though there had never been another option.

Watching her do it was part of what taught me how to do it myself.
