Psych S01E03 - Speak Now or Forever Hold Your Piece

Attorney General Maxwell's son Dylan is getting married. Only problem, the engagement ring, a family heirloom worth $5 million, has been stolen from the safe at the hotel where the wedding is to take place. Shawn, at the police station on another case, sneaks into the interview room where Dylan and his fiancé Bethany are waiting, along with Dylan's sister, and Bethany's maid of honor, Lacey. In the minute he has before Lassiter comes in and catches him, he's able to get all the information on the case -- along with an invitation to the wedding that weekend.
