Ep 11. Lassie Did a Bad, Bad Thing

In Psych season 3 episode 11, titled "Lassie Did a Bad, Bad Thing," detectives Shawn Spencer and his best friend Gus are called in to investigate the mysterious death of a criminal who had just been released from prison. The case seems open and shut until they realize that the man was murdered in a way that could only have been committed by someone in law enforcement.

To complicate matters further, the prime suspect in the case is none other than their friend and colleague, Detective Carlton Lassiter. Lassiter had a grudge against the victim and was among the last people to see him alive. As evidence starts to pile up against him, Lassiter becomes increasingly unhinged and desperate to clear his name.

Shawn and Gus, naturally, can't resist getting involved in the case, even though it means going up against their own police department. They enlist the help of their old friend Harris Trout, a high-ranking official in the Santa Barbara police force, to help them unravel the truth behind the murder and exonerate Lassiter.

As they dig deeper into the case, they uncover a web of corruption and deception that goes all the way to the top of the department. Along the way, they also have to contend with a crooked cop, a vengeful ex-con, and a mysterious woman with a hidden agenda.

As always, the episode is filled with humor, wit, and pop culture references galore. Shawn and Gus are at their best, bouncing off one another with their trademark banter and hijinks. And with the added element of Lassiter's potential guilt, there's a sense of tension and urgency that raises the stakes for everyone involved.
