'Psych's' 100th Episode: Shawn and Gus Investigate a 'Clue' Mystery (Exclusive Video)

Psych is gearing up for its 100th episode.

In "100 Clues," inspired by the 1985 film Clue, Shawn (James Roday) and Gus (Dule Hill) are invited to a mysterious party at a historic Santa Barbara mansion by Billy Lipps, a rock star whom Shawn and the Santa Barbara Police Department sent to prison five years earlier for murder. When a deadly crime is committed, five suspects emerge: the Butler, the Groupie, the Manager, the Author and the Host.

The Hollywood Reporter debuts a scene from Wednesday's hour, wherein Shawn and Gus, with the help of SBPD's Lassiter (Timothy Omundson) and Juliet (Maggie Lawson), investigate a dead body in Billy Lipps' abode. "Great Scott!" original Clue castmember Christopher Lloyd exclaims. Lesley Ann Warren and Martin Mull co-star, along with Tears For Fears’ Curt Smith and Garrett Morris.
