Shawn and Gus investigate who poisoned a food critic. Gus's uncle Burton comes to town and tags along on the investigation, so Gus pretends to be psychic.
Moody newspaper food critic Wagner was poisoned with wild mushrooms. To impress Gus's visiting uncle Burton, Shawn allows an apparent role switch, which means he must cue his clueless partner unnoticed, but hopes to get payment in kind. Shawn soon realizes their first suspect, a disgruntled chef, must be set up by the real poison killer, who is motivated by another competition.—KGF Vissers
