Potential client Brad Webb asks Denver private investigator Reed Ferguson to look into the decades-old murder of Brad's grandfather, Dewey Webb. Dewey was a Denver-based private detective who died mysteriously in 1955, and although Reed is intrigued, he doesn't see much promise in solving the case. After all, the police didn't find Dewey's killer at the time, and 70 years have passed, leaving a cold trail. However, Reed accepts the case, and as he is drawn back into both the underworld and the elite society of 1950s Denver, he realizes that Dewey had discovered secrets that someone still wants to keep hidden today, even if it means resorting to murder. Can Reed piece together old and new clues to find the killer, or will the past comeback to harm him?
