It was Mark’s medical journal.

Seeing it there, in that unlikely place, hit me almost harder than anything else on the table, because it meant that my son had gone looking.

He had not merely stumbled on some letters; he had found his father’s medical journal, wherever I had put it away, and he had studied it, this careful record of Mark’s dying in Mark’s own failing handwriting, and he had used it to understand the debt, the dates, the charges, the whole architecture of what had happened to his father and what it had cost.

I could hardly bear to imagine it: my thirteen-year-old, alone in his room at night, reading his dead father’s account of his own final months, cross-referencing it against collection notices, teaching himself the grim vocabulary of ICU billing and insurance denials, all so that he could go argue with a clerk and save our house.
