"Penny Dreadful" fans will get only eight episodes in the Showtime drama's eerie first season.
But a second season with 10 episodes is on the way, Showtime announced Wednesday.
It's news sure to please fans of Eva Green, who smolders memorably as psychic Vanessa Ives. Production will resume in Dublin, and the second season will air next year.
David Nevins, president of Showtime Networks Inc., announced the renewal and said it was one of the easiest decisions he's 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 bulls-eye with viewers who want to watch television in all the new ways that are available," Nevins said.
Series creator John Logan set the series in Victorian England, where Dorian Gray, Dr. Frankenstein and characters from "Dracula" interact with new figures.
"Logan has deftly created an epic series that has drawn raves from a wide range of audiences from quality drama lovers to critics, to hard-core genre fans," Nevins said.
Showtime highlighted that the series averages 4.8 million viewers weekly across platforms and that it's the channel's No. 1 series ever on Showtime On Demand and Showtime Anytime.
Josh Hartnett and Timothy Dalton co-star in the horror series.
The fifth episode will air at 10 p.m. Sunday and will reveal the bond among Sir Malcolm (Dalton), an African explorer; his missing daughter, Mina (Olvia Llewellyn); and Vanessa, who is pursued by evil forces.
Showtime will offer two series marathons on Saturday. Episodes 101 through 104 will air from 6 p.m. to 10 p.m. and then again from 11:30 p.m. to 3:30 a.m.
