Will there be another series?
Vigil has now run for five episodes, airing weekly on Sundays on BBC One at 9pm.
And the BBC has plunged into talks for a second series of submarine thriller Vigil.
Buoyant bosses at BBC1 are keen to maintain momentum after it became the most-watched show of the weekend, pulling in 5.6million and 5.4million on Monday.
A TV insider said: “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.
Will Suranne Jones return to Vigil?
The insider continued: “It remains to be seen whether Suranne will return, as Vigil’s makers aren’t afraid to kill off a central character.”
What happened in season one?
The thriller-drama follows DCI Silva as she is deployed onto HMS Vigil in Scotland, with the task of solving the murder of Craig Burke.
The series follows Silva as determines whether the death, which came shortly after a fishing trawler vanished at sea, was an accident or something far more sinister.
The series is set almost entirely aboard HMS Vigil, a nuclear submarine. The confined spaces and risk of a murderer at large makes for a sense of claustrophobia, anxiety and fear among the crew.
Silva is helped by her right-hand woman, DCI Kirsten Longacre, who helps her from dry land.
Longacre exposes Silva to the secret and questionable relationship between Elliot Glover (Shaun Evans) and Tiffany Docherty, using a coded message.
However, that is not the only compromising relationship as it is revealed Silva and Longacre have also dated in the past.
When Longacre tracks murder victim Craig Burke’s girlfriend, Jade, in a bid to understand his acquaintances and interests, she finds her also murdered.
The investigation also uncovered a vital incident which occurred while Vigil crew were on shore leave in Florida, when classified documents were exposed by Burke – including a photo of Glover and Docherty together.
