Vigil: 5 crucial things fans learned from tension-filled episode 4

We’re now past the halfway point of the hit BBC series Vigil – and the fourth episode of the crime drama ratcheted up the tension even further.

The latest instalment aired tonight (Sunday, September 12), and found DCI Amy Silva, played by Suranne Jones, continuing her difficult quest to find out who killed Chief Petty Officer Craig Burke on board a Trident nuclear submarine.

And there were plenty of developments as the story took fresh twists and turns.

Stormy relationship

The episode opened with a flashback of an apparent row between Silva and her police colleague, and girlfriend, Kirsten Longacre – suggesting that all wasn’t well in their relationship before Silva went on board HMS Vigil.

Doubts about sanity

Then, later, when Silva presented the submarine’s coxswain Elliott Glover with her theory that he was being blackmailed by Burke, who had proof of Glover’s affair with the boat’s medic, Glover dropped the bombshell to the detective: “Everyone on this boat thinks you’re deranged. It was only me that didn’t.”

Silva was later declared “unfit” by the submarine’s Captain.

Russian involvement

Back on land, viewers saw Longacre apprehend a suspect who she accused of murdering Jade Antoniak, a peace campaigner who was in a relationship with Burke – Longacre realised he may also have burgled her flat, but when she sat down to interview him further, she was pulled out of the room to meet M15 staff who told her the suspect was really a Russian spy and had diplomatic immunity.

And was there a “Russian asset” on the submarine itself?

Chance of sabotage

Commander Neil Newsome, the Captain of HMS Vigil, was told his boat’s reactor could have been tampered with – in the wake of a potentially disastrous “scram” which caused it to be shut down.

A vote on nuclear arms is near

When the Government is told of the troubled situation surrounding Vigil, it emerges that a Parliamentary vote is about to happen about renewing the UK’s nuclear warheads. Longacre and the MI5 are asked “what message it would send out” if the vote happened while Vigil was recalled – breaking Britain’s continuous at-sea deterrent. Nevertheless the order is given to bring Vigil back…

Vigil will return to BBC One at 9pm on Sunday.
