Penny Dreadful is no more.

The Showtime horror series ended its run after three seasons with a surprise series finale Sunday night. The Season 3 finale doubled as a series finale, ending with the death of Vanessa Ives (Eva Green).

Creator John Logan told Deadline that he had always planned to end the series after three seasons, but the creative team and the network decided to keep that under wraps in order to maintain an element of surprise.

"I feel like every show kind of has its own rules and its own rhythms and to say that [the show was ending], given what I knew the ending of Penny Dreadful was going to be, felt like a massive spoiler and it felt disrespectful to the experience that people were having with the show," Logan said.

"I can absolutely confirm it is really over, the end - that's all she wrote," Logan added, but left the door open to revisit the show sometime in the future. In the meantime, he's working on a limited series adaptation of Patti Smith's National Book Award-winning memoir Just Kids for Showtime.
