Detective Superintendent Ian Buckells was unmasked as The Fourth Man (wrongly codenamed ‘H’) after a tense interrogation scene.
But to complicate things, Buckells said there was not simply one ‘H’, blaming multiple OCGs for the actual dirty work, saying: “I just pass things on. They just kept asking me to sort bigger and bigger stuff.”
Fans said they were still left with “many unanswered questions”, with many calling for a series seven.
