Someone has been watching D.A. Rachel Knight - someone who's Rachel's equal in brains, but with more malicious intentions. It began when a near-impossible case fell into Rachel's lap, the suspectless homicide of a homeless man. In the face of courthouse backbiting and a gauzy web of clues, Rachel is determined to deliver justice. She's got back-up: tenacious Detective Bailey Keller. As Rachel and Bailey stir things up, they're shocked to uncover a connection with the vicious murder of an LAPD cop a year earlier. Rachel suspects someone knows the truth, someone who'd kill to keep it secret.
