Excerpt:
Back when he was still Secretary of the Treasury, Alexander Hamilton decided to console a saddened Maria Reynolds. Despite the fact that they were both married, he continued “consoling” her, and “consoling” her until Reynolds’ husband smelled opportunity. He blackmailed the future president$1000 to keep quiet (1/3 of his salary!), but made it clear that Hamilton could keep sleeping with his wife for additional cash.
