Yes, the script is, at times, a smidge on the lazy side (at one point, Frank says, “You just don’t get it, do you!” a phrase which appears so often on the screen that it really needs to be banned). But the tension stays high, and Brighton is as salty a backdrop as one might hope. With three more episodes to come, Sunday night is in safe hands.

The element of suspense was done well early on, with the seconds ticking to the final whistle when the bomb was due to go off. .... The shenanigans over the kidnapping of the two schoolboys was unconvincing and unnecessarily complicated.

There were more interconnections and double-crossings in this single episode than on Rod Stewart’s model railway. It papered over any cracks in credulity by throwing plot and more plot at the wall.
