Vigil Season 3 is already halfway through, with Episodes 3 and 4 now available to watch on BBC iPlayer. BBC One viewers will also get both episodes across the next two nights.

The six-part thriller has a slightly different release schedule depending on how you are watching, with BBC iPlayer releasing episodes in pairs every Sunday while BBC One splits each pair across Sunday and Monday nights. That also means Vigil has two different finale dates, depending on whether you are streaming or watching as episodes air on television.

The latest investigation has reunited Suranne Jones as Amy Silva and Rose Leslie as Kirsten Longacre, this time sending the pair to the Norwegian Arctic archipelago of Svalbard after a British special forces officer is killed during a covert mission. What begins as a murder investigation soon becomes connected to growing international tensions and competing interests in the Arctic.
