English actress Indira Varma (a.k.a. Niobe on HBO’s Rome) is joining the cast of Human Target as a series regular, sources confirm.

Varma, who also had brief but memorable stints on Torchwood (as Suzie Costello) and Bones (as Booth’s UK counterpart Cate Pritchard), will play new team leader Ilsa.

Per the original casting breakdown, Ilsa is described as “sophisticated, driven and principled. She is a widow with a vast fortune that she uses to help better the world. Ilsa finds Chance’s [Mark Valley] lethal methods and his past deeds unacceptable, but she will learn to appreciate (slowly) the altruistic benefits that he has to offer. Ilsa is witty, sexy, clearly in charge and doesn’t take any nonsense from anyone. Chance has met his match.”
