Denton: More inscrutable than a shy sphinx, are her motives finally emerging? Did she have an abortion during or after her relationship with Dryden? And why did she choose the Carly Kirk missing person case? Was it because that’s who Dryden dumped her for, or was she aware of his relationship with her and wanted to turn the screw?
Hastings: In serious financial trouble and under emotional strain, has someone outside the force been leaning on him? Could this visible bastion of standards be dodgier than a pink chicken drumstick?
Cottan: ‘The Caddy’ from the first series of Line of Duty has wormed his way even deeper into police ranks. Did his association with mentor and murdered witness Tommy reach its logical conclusion? This mess of an investigation will only help to cover his tracks…
Prasad: But who tasked him to carry out the attacks? Was it a fellow copper? And why’s he such good pals with Dryden when his girlfriend ended up with him?
Cole: He looked lovely in a wig. We’ll now never know where he bought it from.
Dryden: A predilection for young girls, extra marital affairs, lies over a traffic offence – here’s a chap not averse to deception. But what really happened between him, Prasad, and Carly Kirk?
Fleming: The same goes for you.
Mrs Hastings: Just how much did she want a holiday? She looked ready enough to sanction the murder of four coppers and a witness for a cruise.
Hargreaves: We doubt he’s involved, but we’d love to see him and his grumpy chomps end up in the clink.
Akers: Was she on the take, then? If so, from whom? And who fitted the bug to her car?
Morton: Could he have begun to copy the behaviour of The Caddy, his former colleague?
Them prison guards: Answering only yes or no, do you think they could be behind it all?
Bella the cat: She set Denton up and is then whisked to a new home, free from suspicion. You tell us that doesn’t sound like something a cat would do.
It’s probably going to be him, isn’t it? Although we hope not.
But then who knows what might happen, as the 6.40am time on Fleming’s phone suggests Denton’s prison van was run off the road at 6am. Some early doors ambushing, that.
