Herschel Caine is a master of the universe. His hedge fund, built on the miracle of machine learning, is inches away from systematically sapping profits from the market. His SoHo offices (shoes optional, therapy required) are ready for desperate investors to flood through the doors. But on May 12, his mind is elsewhere - at his Cobble Hill townhouse and the dinner party designed to impress his flawless neighbours. When the soiree falters, Herschel concocts a prank that goes horrifically awry, plunging him into a tailspin of guilt and regret. As Herschel's perfect world starts to slip away, he clings to the moral clarity he finds in the last place he'd expect: a sudden connection with his neighbour's dog.
