Never try to catch a falling knife.

Ex-NYPD detective Evan Adair has finally figured out what’s good for him: to back away from death and allow it its dominion. The truth, after all, never brings the dead back. It’s a lesson Adair has had to learn the hard way.

But when a brilliant young man dies inexplicably by violence – the victim of an apparently impossible crime – the case cries out for a mind like Adair’s. It calls to him like a siren’s song, and he can’t stay away. Not even when it threatens to drag him down for good into the chasm of his own grief.

The mystery draws Adair deep inside the worlds of New York high finance and high-stakes biotech. They’re lands full of strange fauna and complicated lies. The local weapons of choice look like numbers and dollar signs – but the blood they draw runs red. Red as the blood that haunts Evan Adair’s dreams.
