When playing the game of Name the Ripper, many authors start with a suspect and attempt to make them fit the facts; some can't even be proved to be in London at the time of the murders. What is required is an ordinary man local to the East End; a man who suffered mental illness, and was known to prowl the streets at night. A man with vast experience of wielding a knife in his place of work, and who had family ties to Wentworth Model Dwellings, where the only clue ever left by the killer - a bloodied portion of apron - was discovered. A man whose admission to a lunatic asylum coincided with the cessaton of the Whitechapel murders. A man like Jacob Levy. Jacob Levy came to the attention of researchers Neil and Tracy I'Anson many years ago. Their continuing research has brought new evidence to light; sifting through hundreds, if not thousands, of pages of information from various research facilities they came across new undiscovered facts that strengthened their theory, and helped piece together the life of Jacob Levy, including the startling fact that their suspect was a first cousin of Joseph Hyam Levy, the witness at Mitre Square who appeared to be shocked when spotting a man with a woman who was later identified as victim Catherine Eddowes; The Evening News reported that "Mr Levy is absolutely obstinate and refuses to give the slightest information and he leaves one to infer that he knows something but that he is afraid to be called on the inquest." Jacob the Ripper goes some way to explaining the movements of the Whitechapel murderer, the graffiti at Goulston Street, the actions of the police, the 'Lipski' link, and ultimately what happened to the murderer.
