Yes? No? Probably not... (Psych Fan Fiction)

Shawn was torn. This case would be the death of him. All it took for the killer to go free was a simple technicality. That day haunted Shawn's memory for years. By 2012, he thought the past was the past, but when it seems that the killer has resurfaced, he must do everything he can do to solve it once again. The only thing that stands in his way; the diamond ring in his pocket.
