Some I particularly liked in this absorbing story of double -crossing 'twixt police/bad guys/civilians, were a villain who's a caring scoutmaster in his spare time, another crook has to take his illicit son to each illegal meeting, fearful that(a)his wife will find out about the boy(b) that the lad could be a witness against him (c) That unscrupulous criminal colleagues could blackmail him over a and b.
Too, I must confess that I have a weakness for female cops as the leads in films...they've deliberately deglamourised Lesley Hope for this role, but she still comes over as an attractive woman, and a competent cop.
All in all, a serious effort is made to give these characters depth and dimension
There's also lots of mild wry humour in this film, which I voted just short of ten for its reliance on a cliche or two e.g."You're under arrest, bad person!", "Okay, but mind if I turn the t.v. on till my accomplice arrives, so's you can then nab the two of us?" The arresting officers look at each other, then nod agreement. By such devices are filmdon's "bad persons" forever making their escape.
