Detective Harriet Blue is a very good cop . . . gone very bad.

In the space of a week, she has committed theft and fraud, resisted arrest, assaulted a police officer, and is considered a dangerous fugitive from the law.

It's all because of one man, Regan Banks. He viciously killed the only person in the world who matters to Harriet-and he plans to kill her next.

As she recklessly speeds toward the dark side-and finally crosses it-Harriet won't stop until Regan pays for the many lives he has taken.
