Ep 1. Scarlet Ribbons

In The Mentalist season 4 episode 1, titled "Scarlet Ribbons," the team is introduced to a new case involving the murder of a high-end fashion designer named Monica. The crime scene is incredibly grizzly with Monica's throat slit and her body mutilated, leaving the team with a lot of unanswered questions.

As Patrick Jane and the rest of the team begin their investigation, they quickly realize that there is no shortage of suspects in this case. Monica was known for being a bit of a diva and had burned quite a few bridges in the industry. Her business partner, ex-husband, and even a rival designer all had motive and opportunity to commit the crime.

As the team delves deeper into the investigation, they uncover a web of lies and deceit within the fashion world. It seems that Monica's success came at a cost, and she had made enemies along the way. With so many suspects to sift through, the team struggles to find any concrete evidence that can tie any of them to the murder.

Meanwhile, Patrick Jane's personal life is thrown into turmoil when his boss, Agent Lisbon, confronts him about his "psychic" abilities. Lisbon is determined to expose Jane as a fraud and put an end to his charade once and for all. Jane, of course, is equally determined to keep his secrets hidden and his job intact.

As the investigation continues, the team is led down a path that they never expected. It seems that Monica's murder may be connected to a larger conspiracy involving a powerful and dangerous foe. With their suspect list growing longer by the minute, the team must work quickly to put together the pieces of this puzzle before it's too late.

In the end, the team is able to solve the case, but not without some unexpected twists and turns along the way. "Scarlet Ribbons" sets the stage for an exciting and suspenseful season 4 of The Mentalist, leaving viewers eager to see what lies ahead for their favorite crime-solving team.
