What had nearly cost Birdie everything was not a missing check.

It was a building organized, top to bottom, around the instinct to not know — where a cafeteria worker who saw something was told to mind her station, where a report went into a drawer instead of up a chain, where the safest career move at every level was to keep your eyes on your own work.

You do not fix that with money.

You fix it by building a door that is supposed to be walked through, and putting a person behind it whose entire job is to know the things everyone else is incentivized to miss.

I did not want to be the hero of Marbrook Elementary.

Heroes are what a system relies on when its machinery is broken — the lucky accident of one stubborn person in the right place.
