But the emails to my father moved it onto entirely different ground.

Damon had spent months, patiently, working on a retired man he called his family — sitting at that man’s dinner table, accepting that man’s help with the deck, and all the while angling to talk him out of a hundred and fifty thousand dollars of his retirement and into a company built on fraud and floated with stolen debt.

He had looked at my father’s trust, the same trust that had once written a down-payment check with love in it, and he had seen a mark.

That was the thing I could not let stand, and it is the thing that turned my careful, private investigation into something I was willing to carry all the way to a courtroom.
