Stacy Keach returns to The Blacklist in episode 903, “The SPK,” as Vesco, a legendary fugitive and one of history’s most notorious con men. A real-life con man, Vesco’s death is somewhat disputed, so the show presented an alternate history for season 6 episode “Robert Vesco.” The character is No. 9 on Red’s (James Spader) blacklist. Vesco and Red have a long history, and  the last time we saw him, Vesco absconded with the loot they stole on a treasure hunt, swindling Red for the second time.

In Thursday’s episode, Red and Vesco reunite for a new stolen artifacts case and their unfinished business surfaces.

The Blacklist episodes air Thursdays at 8/7C on NBC.
