Penny Dreadful will continue freaking viewers out well into 2015.

Showtime announced today that the uniquely scary drama will return next year for a second season, one that will be comprised of 10 episodes.

Through four installments thus far of Penny Dreadful Season 1, the series is averaging 4.8 million viewers across all platforms and viewings.

Starring Josh Hartnett, Timothy Dalton and Eva Green, Penny Dreadful will go into production in Dublin once again later this year and return some time next year.

Said Showtime President David veins in a statement:

"Picking up PENNY DREADFUL was one of the easiest decisions I’ve made. The series has had worldwide impact, drawing big, passionate audiences on both sides of the Atlantic, and more than any other show on our network has hit the bullseye with viewers who want to watch television in all the new ways that are available.  

"John Logan has deftly created an epic series that has drawn raves from a wide-range of audiences from quality drama lovers to critics, to hardcore genre fans. We look forward to working once again with our partners at Sky Atlantic and are extremely excited for what’s in store for season two."
