What would you do if someone brutally murdered your only child, served only months in jail because of a technicality, and continually taunted, even threatened, you from behind bars? Could you hide your growing rage from family and friends? Could you gun the killer down as he left prison? Could you change your ID and leave behind your entire life - family, friends, jobs, house - and just disappear? Could Tim and Martha Foster do this?
Forensic evidence and criminal behavior expert Dub Walker, along with best friend and homicide investigator T-Tommy Tortelli and ex-wife and TV reporter Claire McBride, employ all their skills to track down the Fosters.
But the murder of Walter Whitiker is not as simple as it seems. Tim and Martha are not the only ones who want Walt dead. Someone has twisted the evidence to keep the hot light of suspicion on the Fosters.
Will the real killer please step forward? Sorry, Dub, you're going to have to work hard to solve this one.
