I have been asked, since, whether I felt satisfaction in that moment, and the honest answer is complicated.

There was a kind of grim professional rightness to it — the feeling you get at work when the last piece drops into place and a thing you have been building for weeks becomes, all at once, undeniable.

But satisfaction is too warm a word for what I felt looking at my father’s face.

It was more like witnessing a law of nature complete itself.

For my whole life these three people had operated on a single unexamined belief: that there were people who took and people who got taken, winners and losers, and that they were permanently, by right, the former.

They had robbed a dying man in perfect confidence because they could not conceive of a world in which the quiet ones win.
