The 6:20 Man by David Baldacci →

This confrontation threatens to dredge secrets from Devine’s past in the army unless he participates in an undercover investigation into his firm.

This role will take him from the impossibly glittering lives he once saw only through a train window and even the expected routine of the financial world he is now part of to the darkest corners of the country’s economic halls of power.

As he commutes to work on the 6:20 train and looks out the window, he knows the killer may live there. He is now part of a high-stakes conspiracy, and Devine has a target on his back.
