This film has recently surfaced on Movies4Men.It is the sort of police drama that would be the support to some big American film at the Odeon or ABC.Ian hendry who stars in this ,should really have become a big star,but his career spiraled downward in the seventies mainly due to his drinking which eventually killed him at a very early age.I in fact saw him in a sorry state in a pub in Golders Green Road.The film is really a bit of a mess.There are too many suspects with lots of red herrings.the murderer is rather unlikely with no clues given as to the killers identity.The detectives always just get home when the phone rings and they have to go out again.You just wonder at the great overtime bills they must be clocking up.They literally plod around crime scenes picking up items willy nilly in a way that could easily wipe any prints.Clearly no SOCO at that time.Ronald Fraser plays the slightly comic detective.However i have to say that all this film induced in me was sleep.
