The show starts on August 30 on BBC One, with two episodes dropping weekly in iPlayer.

Vigil series 3 — this time the trail is getting cold, very cold

With series 2 taking us to an airbase in Scotland, this time round our investigating due take us further North. As the latest press release tells us:

DCI Amy Silva (Suranne Jones) and DI Kirsten Longacre (Rose Leslie) return for a high-stakes investigation that takes them to a remote Arctic research station, where a member of a covert British special forces mission has been shot dead.

Amy and Kirsten will need to catch the killer and defuse a potential international confrontation, as different nations compete for control of the Arctic and its resources in the changing polar climate, with both their careers and relationship on the line. As the mission rapidly unfolds, Amy and Kirsten begin to question who they can trust.

Alongside Suranne Jones and Rose Leslie, the trailer shows the return of Dominic Mafham, reprising his role as Sir Ian Downing, as well as new cast for series three: Jeppe Beck Laursen (The Last Kingdom, The Trip) as Henrick Becken — Svalbard’s Chief of Police; Naomi Yang (Under Salt Marsh, Wolfe), as Shen Jia — a microbiologist; Tornike Gogrichiani (Extraction 2, Drops of God) as Fyodor, a Russian Colonel; Steven Miller (Dept. Q, Shetland) and Benjamin Wainwright (Maigret, Belgravia: The Next Chapter) as Special Boat Service operators, Mark Cunningham and Oli Pickford respectively; Danusia Samal (Red Eye, The Great) as Jasmine Kelly, working alongside Sir Ian Downing; Eric Godon (In Bruges, Anna) as Mayor Korotayev, and Amy Manson (Rebus, Bodies) as Lorna McCallister, a geologist. Gary Lewis will also be reprising his role as DSU Robertson who continues to work closely with Amy and Kirsten.

Further cast are listed in the press release. The show returns to BBC One at 9 pm on Sunday, August 30. Here’s the trailer:
