Psych - Season 2 - Eps 7: If You're So Smart, Then Why Are You Dead?
Shawn and Gus take on academia as lecturers at a school for the gifted where two students suspect a teacher of murder, they just don't know who's been murdered or the murderer's identity. At the precinct, Juliet lobbies hard for lead position on the next case, and Lassiter hands her a "gimme". The same case Gus and Shawn are working.

Synopsis
Thanks to his police officer father's efforts, Shawn Spencer spent his childhood developing a keen eye for detail (and a lasting dislike of his dad). Years later, Shawn's frequent tips to the police lead to him being falsely accused of a crime he solved. Now, Shawn has no choice but to use his abilities to perpetuate his cover story: psychic crime-solving powers, all the while dragging his best friend, his dad, and the police along for the ride.
