'Truth will come to light, murder cannot be hid long, a man's son may, but at the length truth will out.', said Launcelot in The Merchant of Venice. Whilst the passage of time can and has uncovered many secrets, killers could get away with their crimes in 1596 when Shakespeare penned these words and this is certainly the case in more recent times as Unsolved Murders in South Yorkshire clearly demonstrate. The early chapters include cases of historic interest where killers certainly went to the grave in the knowledge they had got away with murder. Cases include suspicious deaths which left detectives in South Yorkshire baffled, but which were, it would seem, acts of callous murder which were not recognised as such due to dubious police opinions and practices. There are also cases of clear murder such as a man shot in the head during the Victorian period, whose killer was never identified. The later chapters, however, feature more recent cold cases where there is still the possibility that the wicked men or women who were responsible for such acts of inhumanity may remain within our society. Cases include a man murdered for less than GBP70 in a city centre multi storey car park, a teenage girl abducted, sexually assaulted and left dead on a dung hill, a young mother who entered prostitution and died at the hands of a man with more than sex on his mind, a pregnant woman who left home one day to go shopping but was found days later dead in a ditch with her throat cut and a disabled woman who was strangled in her home which was then set ablaze. For some of these cases there is the chance that someone has information which, despite the passage of decades, could lead to one or more individuals standing trial for murder. Justice can still prevail.
