The Blacklist's Liz Keen will have a terrifying new foe in season 3. As if the fugitive didn't have enough problems to deal with as it as.

'The Blacklist' Season 3: Which New Blacklister Was Announced? Episode 2 Title Revealed

The NBC series has begun filming for its September return, and X-Men First Class Edi Gathegi is set to make frequent visits to the New York City set.

Gathegi will play Mr. Solomon, according to Entertainment Weekly, who is described as "a monster in gentleman's clothing." Sounds like Solomon and Red (James Spader) should start a club - criminals without a closet of three-piece suits need not apply.

While the Cabal is as dirty as it gets, it seems Mr. Solomon will be in charge of their more...unsavory...transactions.

"[Solomon] essentially handles the dirty work for the Cabal," Entertainment Weekly teased. "Unassuming and soft-spoken on the surface, [Solomon has] a hidden (and terrifying) capacity for violence."

The Cabal has deep pockets and an even farther reach. Liz Keen (Megan Boone) and Red have topped the bureaus most wanted list, and thanks to the former profiler's decision to kill Connolly (Reed Bimey), the Cabal will be ever eager for her capture.

Catch the The Blacklist when it returns to NBC Thursdays at 9 p.m. ET this September.
