So I did the hardest operation of my career.

I retired the man I had been.

I buried him so deep that even I could almost forget he was down there.

And in his place I built Alexander Sterling, an ordinary widower who consulted on building-security systems and coached nothing more dangerous than his daughter’s grade-school science projects.

For nineteen years, that had been not just enough but everything — the best and truest work I have ever done.

Being Chloe’s father was the only mission I had ever run that felt like it was on the right side of things.
