The clause only bites a person who lies on it, and an honest man in Jonathan’s position would have set down the pen, asked for a private word, and said, there is a matter I need to disclose before I sign this. It would have complicated his deal.

It would not have destroyed him.

What destroyed him was not my clause; it was his own reflexive, total confidence that the truth of what he’d done to me simply did not count — that a split lip and a thrown-out wife were beneath the notice of anything as important as his funding, not even worth the pause of a disclosure.

He signed my reputation is spotless eighteen hours after splitting his wife’s lip, and he meant it, because in his mind what he’d done to me was not a stain on his reputation at all.
