Showtime is ordering a second season of Penny Dreadful. The Victorian-era horror thriller starring Josh Hartnett, Timothy Dalton and Eva Green has been picked up for another round. The premium network is committing to 10 more episodes from writer-producer John Logan, an increase on the first season’s 8-episode order.

“The goal here was to see if we could do a genre show a horror show but with all the sophistication and depth of a Showtime show and John Logan ended up being the person to do it,” Showtime president David Nevins tells EW. “It’s been well reviewed by mainstream critics, it’s giving us a Comic-Con-appeal show. It’s a whole new world as imagined by Logan.”

Nevins says the rest of the first season will involve a continued expansion of the world of the show and a deeper exploration of the current characters. “It just gets richer deeper and more complicated with the characters,” he says. “We’re only four episodes in and you’re only just getting a taste of what’s to come.” The first season will also provide closure to the current main story arc, involving the search for Sir Malcolm’s (Dalton’s) lost daughter.
