Paydown by Nick Stephenson
Greed can be murder...
When a high-flying Wall Street investment banker is found brutally killed, what started out as a simple fraud case turns into expert criminologist Leopold Blake's first ever murder investigation.
Now, with the financial world at the brink of collapse, Blake must put aside his differences and work with NYPD Detective Mary Jordan to find and stop the killer before it's too late. As the glamor of Wall Street is stripped away by a series of catastrophic discoveries, Leopold will have to decide how much he is prepared to risk in order to uncover the truth - and whether it's a price he's willing to pay.
