Ryan Murphy will continue to scare up viewers with a fourth installment of FX anthology series American Horror Story. The third season Coven is the most-watched season of AHS to date averaging 7.7 million viewers.

“Put simply, Ryan Murphy is a master television producer,” said FX head John Landgraf. “Time and time again he reinvents the form. What he, co-creator Brad Falchuk and their producers Dante Di Loreto, Tim Minear, Jennifer Salt, James Wong, Brad Buecker, Jessica Sharzer, Douglas Petrie, Alfonso Gomez-Rejon, Alexis Martin Woodall and the entire production team and cast responsible for the American Horror Story franchise have done is nothing short of extraordinary. Every year, they create a riveting and brilliant new miniseries. AHS: Coven is the best yet, and I have no doubt that the next installment will be even better.”

The 13 episode fourth season is set to debut in 2014. Though the season’s theme and stars are still being kept under wraps, Jessica Lange has publicly confirmed that she will return to the show to step into a new character’s shoes.

AHS: Coven airs Wednesdays at 10PM on FX.
