I won't give chapter and verse on the background of this tale, as I imagine that if you view this film you are aware of the 3 murders in Rettingdon and associated issues. This film is interesting and covers a few of similar cases. Some of the cases and the way in which they are presented seems like a plea to the viewer as to the validity of the criminal case against the criminals. This, I feel is probably best approached in another film or documentary. However, my main issue with the film is that an awful lot of the material used, mainly interviews with Bernard O'Mahoney's acquaintances, is a simple re-run of O'Mahoney's episodic TV series (now on DVD) about the underworld in Britain. These 2 series are very interesting and well worth a watch (British Gangsters: Faces Of The Underworld – Ser 1 & Gangsters: Faces Of The Underworld Ser 2). If, like me you have seen these 2 series then this film will feel much like watching repeat of hi-lights from the 2 series, which is very disappointing. Naturally some tit-bits are added so as to be able to call it "new" material or "the truth". In reality it is a very interesting watch but in the end, as viewer who is aware of the details of the crime will know no more than they did before viewing the film. 6/10
