5 January, 1982

Rick and A.J. receive a letter in the mail that was originally sent twenty-three years earlier, but contains a clue to the murder of the letter writer, who died the day after he mailed it. As they investigate, they soon learn that Conrad Viorst's death is also connected to the death of a burger baron who died that same year, and Conrad's now-grown daughter Andrea is endangered by the investigation. The brothers are convinced that taco baron Ben Dodge is behind everything, but they need to find proof.
