'The Devil's Hour' will return for a second and third series.
The Amazon Prime Video thriller will see Jessica Raine and Peter Capaldi reprise their respective roles as Lucy Chambers and Gideon, alongside Nikesh Patel, Phil Dunster, Meera Syal, and Benjamin Chivers.
Dan Grabiner, head of UK Originals, Amazon Studios, said: "We're thrilled with the audience response to 'The Devil's Hour', and can't wait to share the next chapter of this mind-bending story.
"Fans can look forward to plenty more twists and turns in this remarkable tale from first-time series creator Tom Moran, and welcoming back our immensely talented cast, led by Jessica Raine and Peter Capaldi."
Series one sees Lucy on the hunt for serial killer Gideon, whose true intentions are later revealed.
Filming on the next series will start early next year.
'The Devil's Hour' is written by Tom Moran, and executive produced by Tom, Steven Moffat, and Sue Vertue.
Sue, executive producer and CEO of Hartswood Films, said: "It goes without saying that we are over the moon to be continuing Lucy's story with two more series.
"Tom Moran and his big brain have so much more planned for us all.
"This was always envisioned as a three-series arc, and it's going to be a thrilling ride."
Tom, writer and creator, added: "Series One of 'The Devil's Hour' was just the beginning - the opening act of a TV novel.
"I'm so thrilled that we get to keep turning those pages and slotting the puzzle pieces into place.
"If you thought the final episode of Series One had all the answers, then you haven't been asking the right questions."
