Weak ending.

The accountant's death and Jackies involvement are never fully explained, but I think it's highly unlikely that anyone would accidentally kill their own accountant in a random road accident - especially given the kind of business they were involved in - and more to the point the kind of people they were involved with.

So yes, I think she was in with Tommy. The whole thing including the affair and the dead accountant was probably part of an elaborate set-up. If Jackie was working for Tommy he obviously decided to get rid of her, possibly because she failed to make Gates accomplice (Gates kept insisting that she tell the truth about the hit-and-run). So with Plan A to gain control of Gates a failure, it seems likely that Tommy moved onto Plan B - having her killed and incriminating Gates to make him his puppet.

The only alternative I can think of is that Jackie wasn't willingly working for Tommy, but was set-up by him. Perhaps his men threw the already dead accountant in front of her vehicle? And after that Tommy blackmailed her into doing whatever he wanted. In exactly the same way he tried to blackmail Gates.

Arnott had become a nuisance and would have eventually been murdered.

The drug-dealers who had their fingers removed. I assumed Tommy wanted to know who they were working for, who supplied them etc. Then he executed them to make an example of them.

Well, that's my take on it for what it's worth. I understand where you're coming from though, none of it was fully explained. I suppose the program makers want to keep us guessing.

Surely there will be a Line of Duty 2? I hope so anyway, I think it has legs.

"And does anybody on earth including Mercurio know why that damned crystal tumbler is sitting on the shelf in the cop shop kitchen?????????????????"

It's hiding in plain sight. Gates had no time to dispose of it properly, and was unable to chuck it into the lake because of the early angler.

The only people who knew its significance were Arnott and Fleming, and given their status within the station they were hardly likely to be found in the kitchen/dining area. So that location was safest, certainly until the heat was off.
