ABC has found its latest leading lady.

Sherlock Holmes' Kelly Reilly has landed the starring role in the network's limited series The Black Box, The Hollywood Reporter has learned. The series will revolve around Elizabeth Black (Reilly), a famed neuroscientist who seems to have it all, but struggles with mental illness -- one of many secrets she keeps from her fiancé and family.

For the English actress, this is her first stateside series television part following a string of features including playing Mary Watson in the Robert Downey Jr. Sherlock features as well as British TV series including Above Suspicion and Wonderful You. 

Black Box was written by Amy Holden Jones (Mystic Pizza, Indecent Proposal), with Simon Curtis (My Week With Marilyn) on board to direct. The drama will be executive produced by Anne Thomopoulos, Bryan Singer, Ilene Chaiken and Oly Obst, with Chaiken (The L Word) set to serve as showrunner.

ABC picked up Black Box straight to series with a 13-episode order in June. The drama marks the first small-screen foray for independent production company Bold Films (Legion, Drive, Only God Forgives), with Sierra Engine tackling international distribution. WME packaged the deal and presold it internationally before the project was scooped up by ABC.

A premiere date has not yet been determined, though the project is being eyed for a January bow contingent on how ABC's freshman class fares.

Curtis is repped by UTA, Anonymous Content and Independent in the U.K.
