Psych: Game, Set... Muuurder?

Shawn's powers of observation work against him when he cannot help but reconcile his gorgeous Friday night date with her ex-boyfriend after solving the mystery of his series of white lies. Now alone in a bar, he spots Lassiter at a table, drinking heavily, marking a sad anniversary. Lassiter invites Shawn over and proceeds to pour his heart out, confessing that Shawn's skills astound him. While he doesn't believe he's psychic, Shawn somehow guarantees an arrest, whereas Lassiter, who used to be a great cop, now can't even solve the murder of a local astronomer. Everyone thinks Bryant Vallery died of natural causes, but the guy was relatively young and lived a healthy lifestyle. Lassiter tells Shawn that he knows there's more to it but can't prove it - then proceeds to pass out.
