I sat behind a machine for fifty minutes and made a verbatim record of a woman explaining, to about two hundred pediatricians, the healing timelines of infant fractures and the specificity of posterior rib injuries, using a set of films that were not my niece’s.

And afterward I waited by a table with a coffee urn on it for eleven minutes like a lunatic, and when the last person had finished with her I said: “Dr.

Bright.

I don’t expect you to remember me.

October 2022.

Femur and three ribs, six-month-old, the aunt with the note.”

And Dr. Halima Bright said, immediately: “Restrepo.”

I said that I had never thanked her.
