I want to note the thing I heard in her voice in that hallway, because it was the first crack in two years of a perfect performance, and I almost talked myself out of it.

When I said I needed five minutes, and she pushed back, her voice dropped — beneath the sweetness, for just a sentence or two — into a register I had never heard from her: tight, hard, controlling, with an edge of real menace under the wedding-day gloss. This is no time for games, Thomas. It was gone almost as fast as it came, papered back over with the smile.

And a day earlier I would have missed it entirely, or explained it away — wedding nerves, the stress of the moment, anyone might be sharp.

But I had my grandson trembling behind my leg and a flash drive in my breast pocket, and so for the first time in two years I actually heard her, instead of hearing the version of her I wanted.
