1. Lock, Stock, Some Smoking Barrels and Burton Guster's Goblet of Fire

Using a “ Guy Ritchie ” style voiceover, Shawn and Gus recount being summoned to London by Interpol to take part in an undercover sting operation against ruthless criminal Ronnie Ives ( Vinnie Jones ). Since Gus is more interested in attending a Harry Potter convention, he has to be strong-armed into a case yet again. They also learn that they were called in by Pierre Despereaux ( Cary Elwes ), who tells them he's been undercover for the last 10 years. Doubting his story, Shawn calls Lassiter for help, and he's more than happy to assist since he's been demoted. Note: This is the first episode of the show in which Corbin Bernsen does not appear and the first since the Pilot in which Maggie Lawson doesn't appear (although both are credited).
