Vigil has wrapped up its first series on BBC One and fans already want to know if there will be a second.
The series is made by World Productions (Line Of Duty, Bodyguard) and has been written and created by Bafta-nominated writer Tom Edge (Judy, The Crown, Strike) with episodes by Ed Macdonald (The End Of The F***ing World) and Chandni Lakhani (Dublin Murders).
The first series starred Suranne Jones (Gentleman Jack, Doctor Foster) as DCI Amy Silva who led an investigation into a death on-board a Trident nuclear submarine.
Will Vigil return for series two?
At the time of writing BBC One has yet to confirm what's in store for Vigil.
Series 2 of Vigil hasn't been officially announced - but sources say talks are underway for more after hit ratings for the first run.
A source shared with The Sun newspaper: "The Beeb knew they had a hit on their hands. So they’ve been in discussion for some time with its creators, World Productions, about a potential follow-up.
“Now those plans are likely to progress at speed, with a view to Vigil II being commissioned."
