As previously mentioned in a prior review, "Leyton was celebrating his birthday with his fellow police officers at his workplace. His fiancée came up in order to take him out for dinner. They got into their car in the (underground) garage when a biker bumped into them, blocking their way out. Shortly after(wards)," the biker shoots Leyton dead.
That's all true, but it is misleading in that it ineptly sets up the murder of Leyton. As Leyton and his fiancée head down to the underground garage, there are cross cuts of their descent into the garage with the biker (motorcyclist) heading toward the underground garage (implied). Sure enough, as Leyton and his fiancée get to and enter their car, the motorcyclist has descended to their parking level and parks directly behind Leyton, bumping their car with his front tire. Leyton prepares for some sort of confrontation with the motorcyclist and rolls down his window to start a conversation. Within seconds, the motorcyclist confronts Leyton with a pistol and is shot dead at very close range. The motorcyclist absconds, setting a train of events into action.
The problem is (1) how in God's name did the motorcyclist KNOW when Leyton would leave the party?; how in God's name did the motorcyclist KNOW on which level of the underground garage Leyton's car was parked?; how in God's name did the motorcyclist KNOW exactly when to arrive at Leyton's car to kill him?
The plotting SCREAMS that SOMEONE AT THE PARTY called the motorcyclist to tell him that Leyton was about to leave so that he can get the ball rolling, but that particular vexing.issue isn't even addressed, much less addressed and dismissed or explained. Sloppy, sloppy, sloppy.
I've seen all the episodes of "Law & Order UK". This is the first amateurish blunder, indeed, the first and only blunder as far as I can recall, that occurred in any of the episodes.
