The fourth season of the American crime thriller television series The Blacklist premiered on NBC on September 22, 2016.

[2] The fourth season resolves the question of Alexander Kirk's (Ulrich Thomsen) relationship to Elizabeth Keen (Megan Boone).

Reddington (James Spader) attempts to kill Mr. Kaplan (Susan Blommaert) for her efforts in hiding Liz and her baby from him, but Mr. Kaplan survives the attack and begins exposing the trail of dead bodies left by Reddington’s criminal activities.

The final episodes reveal the existence of a suitcase containing human bones of unknown origins that figure prominently in the next season.

The consensus reads: "Propelled by the sheer force of James Spader's performance (and a pretty killer soundtrack), The Blacklist's fourth season ups the ante and then some".
