We know Richard Longcross is a covert operative. But why has he been spying on Budd’s family?

Longcross, played by Michael Shaeffer, also passed on dirt on the Prime Minister to Julia. Did the secret service hope to install her as PM?

Why did the relationship go “sour”, according to David? Why did Nadia identify him as the man who gave her husband the train bomb?

Some fans think he could be Budd’s ex-wife’s boyfriend. Matt says he is a “real suspect” but “what’s his motive?” MURDERER MARK: 7/10
