During the midseason finale of "Suits," fans were shocked when Mike Ross (Patrick J. Adams) was arrested for conspiracy to commit fraud just as he was about to start over and live an honest life with his fiancee Rachel (Meghan Markle).

When the show returns to USA Network next year, the story will focus on his arrest and the resulting investigation, and the remaining six episodes of the season will also show how his loved ones and his co-workers have been affected by this.

In a new promo released by the network titled "Who Sold Mike Out," it looks like Mike's mentor, Harvey (Gabriel Macht) is going to try to find a way to get Mike off the hook. Given that Harvey resigned from the firm in order to protect it from a hostile takeover, what Harvey is about to do is certainly no easy task.

In the preview for episode 11 titled "Blowback," Harvey is heard saying, "The first thing we need to figure out is who tipped him off." Mike is seen being led away, and there is glimpse of prison bars being slid open. He is also seen in prison and looking very worried about his future.

The words "Who Sold Mike Out" flash on the screen, and fans are encouraged to go to suits.usanetwork.com to vote among Daniel Hardman, Dana Scott, Logan Sanders, Louis Litt, Claire Bowden, Professor Gerard, Jack Soloff, Katrina Bennett, Charles Forstman, Sheila Sazs, Dr. Paula Agard, Trevor Evans, and Jeff Malone as the most likely person who sold Mike.

Mike is heard saying, "I wanna know if you're the one who turned me in" as the names and photos of the possible culprits are shown.

Speaking to The Hollywood Reporter last August, showrunner Aaron Korsch said that whoever snitched on Mike "could have been a friend, a foe, a neutral party, or someone who has never even met Mike." At this point, it's anyone's guess as to who sold him out until the season 5B premiere.

"Suits" returns Wednesday, Jan. 27 at 10 p.m. on USA Network.
