Dis-Lodged

S2, E14: Henry is sick, Shawn tells Gus. He called to cancel their weekend camping trip in the mountains and Shawn couldn't be more thrilled, until he catches his dad driving through town, the picture of health. Now Shawn has to know why he was ditched, and he and Gus follow Henry to the Monarch Lodge, where they discover Henry is a member. After Shawn perfectly repeats the secret handshake, they enter the lodge to find Henry in a room full of robed lodge members, surrounding a dead body on the floor. The brothers have called Henry in for help, but he insists he's retired both from the force and the lodge and calls the police.
