A Falling Knife

In a landscape strewn with dollars, how do you catch a killer who's playing for higher stakes than money? Ex-detective Evan Adair has a gift for working out how the dead got that way, but the truth never brought anybody back. After twenty-three years at the NYPD and a devastating private loss, he wants no part of another investigation. But an old colleague comes calling with a tantalizing riddle. A Wall Street wunderkind, a young quant with everything to live for, has taken a bizarre public dive from an opera balcony. Was the fall his own idea? And his injuries, as it turns out, weren't enough to kill him. So how -- and why -- did he die? Soon there is another death, this one a vicious knife attack. The dual investigation draws Adair into the byzantine worlds of finance and high-stakes biotech. He finds secrets with long histories and numbers that can talk -- if only he can figure out how to listen.
