Fallen

An investigation becomes personal for Detective Ryan Winter when a colleague and friend is shot dead, the second victim in just weeks. For Dr. Lydia Costa, an ER physician at Atlanta's busy Mercy Hospital, the recent police slayings reopen barely healed wounds and bring her face-to-face with her ex-husband, Ryan Winter. As the body count rises and paranoia tightens its grip on the police force, Lydia and Ryan are pulled together by circumstances. But as Ryan moves closer to discovering the killer's identity, someone is watching, placing both him and Lydia in mortal danger.
