Ian Buckells eh? Despite being the subject of an H theory fairly early on this series (on account of some golf clubs in his office), we’d be willing to bet that the confirmation of Buckells as the apparent mastermind behind the clandestine network of police corruption had you surprised. As Kate Fleming rightly pointed out, she's worked with him a number of times before and he's been right under AC-12's noses this whole time. Actor Nigel Boyle previously teased, during a 2017 interview with Digital Spy, that "there's definitely more to Buckells than meets the eye" – and he sure wasn't wrong!
