Looking for Psych recs, Shawn/Lassiter

I realize we don't really have enough folks in the comm yet to get  responses to these earlier posts, but I'm hoping people will go through tags when they join and leave responses to older posts.  Or maybe I'll just get lucky:)  Plus, you know, it doesn't hurt to have example posts...

I'm looking for Psych fic recs, preferably long stories with plots and happy endings (if such a monster exists in the Psych fandom).  Shawn/Lassiter please.
