Eve and Villanelle’s twisted love story is coming to an end. BBC America announced that “Killing Eve’s” upcoming fourth season will be its last, but the network is “developing a number of potential spinoffs,” according to Deadline.

Based on Luke Jennings’ book series, “Killing Eve” revolves around British intelligence investigator Eve (Sandra Oh), psychopathic assassin Villanelle (Jodie Comer), and their mutual obsession with one another and its ensuing body count.

The hit show was created by “Fleabag’s” Phoebe Waller-Bridge, who served as head writer on its first season. Emerald Fennell (“Promising Young Woman”) took over over the role in Season 2 and Suzanne Heathcote (“Fear the Walking Dead”) was handed the reins in Season 3. Laura Neal, whose credits include “Sex Education” and “Secret Diary of a Call Girl,” is Season 4’s head writer.

Comer won an Emmy for her role in the series and Oh snagged a Golden Globe.

While the “network and production company didn’t disclose specific spinoff ideas and sources suggest that there’s nothing firm in the pipeline,” the source reports that “it’s clear that the AMC Networks-owned [channel] is keen to extend the ‘Killing Eve’ universe.”

“’Killing Eve’ exploded in popular culture and attracted a dedicated and committed fan base from its very first episode. Phoebe Waller-Bridge’s brilliant adaptation of the source material, the unforgettable characters given life by Sandra Oh and Jodie Comer, and the entire cast, along with our partners at Sid Gentle Films, have delivered a one-of-a-kind roller-coaster ride that has taken our breath away,” said Dan McDermott, president of original programming for AMC Networks. “We could not be more thankful for the extraordinary talents and efforts of everyone involved, particularly Sandra and Jodie, who made ‘Killing Eve’ much more than a television show. We look forward to what is sure to be an unforgettable final season and to exploring potential extensions of this compelling universe.”
