'The Mentalist' Season 6 Episode 17 Spoilers: Jane and FBI Work to Prove a Man's Innocence

Jane and Lisbon teamed up to catch murderous art thieves on the latest episode of "The Mentalist."

In "Violets," the FBI is investigating the death of John Hennigan, the owner of an art gallery. He was killed by a group of art thieves, who then pilfered a bunch of his paintings. Jane (Simon Baker) tells Abbott (Rockmond Dunbar) about the case, thinking they should work together to track down the thieves. 

The FBI art theft squad is also working on the case, which includes special agent Marcus Pike (Pedro Pascal). Pike says they have been looking for the thieves for awhile, but they have only identified one of them. 

Jane then comes up with a plan to go undercover to lure the thieves to seal expensive art, then catch them in the act. Jane and Lisbon (Robin Tunney) go undercover as a cultured married couple who own a large home full of expensive art. Abbott, Fisher (Emily Swallow), Cho (Tim Kang) and Wylie (Joe Adler) are also involved in the sting. 

Meanwhile, Pike is showing some noticeable interest in Lisbon. 

Jane's plan works, and the FBI is able to capture the rest of the art thieves, including the boss, who killed Hennigan. 

Afterwards, Pike asks Libson out for dinner, and Lisbon agrees. Jane finds out that the two are going out on a date, and he is clearly not happy about it. 

On the next episode, "Silver Wings of Time," "With only two days before a man is executed, the FBI and Jane attempt to solve a cold case and prove the man is innocent."

The episode "Silver Wings of Time" airs Sunday, April 13 at 10 p.m. EDT on CBS.
