He was suspect number one - the man who tried to kill Deputy Mattie Cobb and may have killed her father thirty years earlier. But when Mattie and cold case detective Jim Hauck reach the Colorado state prison where they will finally get to interview him, he's found dead in his cell. There's only one clue: a map leading to Timber Creek and rugged Redstone Ridge. Then Cole goes missing, stranded alone in the high country with a person that Mattie now suspects is the mastermind behind several murders - but the killer has a cold-blooded plan that threatens them all.
