Gus' s Secret

[redribbongirl3]

I'm looking for a specific fic. It about bones of a young girl in a cave and it happened when Gus was young. But no one found it until after Shawn and Gus became private detectives. SBPD thought it was a girl named maybe Angela but the truth is that she ran away maybe with Gus help and the body belong to Gus and his friend bully's sister. I think she was accidentally stab or push. The bully had a knife and was planning to stab Gus or his friend. The only one who knew was Gus, his friend and the bully. I think it shassie pairing. It was on ff.net or ao3 because those two sites are only I use to read Psych fanfiction. I think it completed.

Thank You
