Rage, I had learned a long time ago, is loud and useless; it warns your opponent and accomplishes nothing.

What I felt, driving home through the dark, was not rage exactly.

It was a cold, clear, settling focus, the feeling I used to get in the moments before something serious, when the noise in my head went quiet and there was only the problem and the steps to solve it.

I picked up my phone and I called my mother.

She answered in a low voice, the voice of a woman who has stepped into another room to take a call she does not want overheard.
