Chivalry Is Not Dead... But Someone Is

Shawn and Gus show up at a crime scene at a swanky mansion where a young bachelor, Lance, just fell to his death. Lassie doesn't believe it was murder, but Shawn thinks otherwise. He notices that Lance's ankles and arms were not broken, causing him to believe that he didn't try to brace his fall and was therefore dead before his body touched ground.
