When Detectives working on some of these cases start turning up dead, Emma knows that she's onto something. These deaths are murders, and she's going to be the one to prove it.

The closer she gets to finding the killer, the more Emma feels like she's being watched. Is she setting a trap for this depraved killer? Or with every step she takes, is she falling further into his...?
