Death Star, for instance. Keeley Hawes is clear and eloquent as Home Secretary Julia Montague. Before she 'ambushes' the Prime Minister she turns to David Budd, her personal protection officer, and tells him to go to the Death Star if she doesn't return. It's a photograph she named in an earlier episode.
Eventually, David Budd follows -up the Death Star reference and finds the kompromat that everyone is seeking. With whom will he share these toxic revelations, now he feels even Detective Louise Rayburn has betrayed him? Kompromat: damaging allegations, compromising material. In this case revelations about the Prime Minister.
And what is Budd doing meeting secretly with an arms dealer and trying to get hold of an untraceable rifle? I reckon he's pursuing his theory that the assassination attempts on Julia Montague involve organised crime trying to suppress her RIPA 18 legislation. He knows his Helmand associate Andy Apsted had such a weapon. Finding how it was sourced might lead him to the bomb builder.
Looking back over all those terrorist/ assassination attempts are they all linked? Even that episode with Nadia on the train. Was it chance that David Budd was on that train, or part of the plan? In the same way the choice of his kids' school as bomb target was not haphazard?
We know Hunter-Dunn, Head of Security Services, is on the dark side. But what about Tom who looked shifty at St Matthews College and kept clear of the explosion. It was he, not DI Louise Rayburn, who ensured David Budd was stood down and stripped of the right to carry firearms.
Will Jed Mercurio give us all the answers? Or leave some threads tightly knotted so we have to go on unravelling. It's working. Can't think when a drama had everyone so engaged, so eager to second- guess the plot.
Rob McDonald tried to sabotage Julia Montague's speech. Hoping for a memorable gaffe. Vince Cable showed us how. Try John Crace, The Guardian Political Sketch writer on VInce's performance. It's hilarious.
