And the greatest thing my father did, in that hospital room, was not whatever the tattoo meant.

It was that he did not use it.

He had every reason and every right, by the world’s rough arithmetic, to become the man Gerald feared.

And instead he drew the curtains, and he let his granddaughter’s mother keep the evidence she’d gathered, and he opened the door for a detective, and he chose the law over the darkness — chose to be, in front of me and my daughter, a man of peace who was capable of a great deal else.

That was the lesson.
