Shawn and Gus are on the slopes on their ski vacation in Whistler, British Columbia when Shawn spots wanted international art thief Pierre Despereaux. Despereaux is so good, he's never left enough evidence behind to be formally accused and so promptly gives Shawn and Gus the slip. Shawn goes to the Mounties for help, who need very little convincing of his psychic abilities. Deputy Commissioner Dykstra calls Lassiter to ask for Despereaux's files to be sent up, and Lassiter insists on being part of the investigation. Lassiter and Juliet arrive in Canada just in time to meet Shawn and Gus at Despereaux's latest crime scene. The thief has stolen an antique necklace worth several million dollars. Shawn notices a spot on the wall where a painting used to be and assumes Despereaux stole that as well. The owner says he sold that painting two weeks ago. Lassiter sees all the telltale signs of Despereaux - no fingerprints, no alarms tripped and a signature Merchanteuse Blonde cigarette burning in an ashtray - but not Despereaux himself. Shawn spots flowers in a vase inexplicably moving, like in a wind. But they are in a high-rise condo. Shawn tracks the source of the breeze to a window slightly cracked open. He pushes the widow open and looks up to see a shoe disappearing onto the roof. Shawn rejoins the group and claims Despereaux is on the roof of the building. Lassiter is skeptical, but Shawn and Gus race up to catch the thief, who compliments them on a vast improvement on their skills from the horrendous skiing of the day before. Then he excuses himself, saying he's going back to his room - and jumps off the building. By the time Lassiter and the rest of the Mounties arrive, Despereaux has disappeared, leading everyone except true believer Corporal Mackintosh to doubt he was ever there at all.
