This account of the Ripper murders of 1888, uncovers much new data, including what is appparently a sighting of the murderer and a murderous assault bearing all his hallmarks. This list of suspects is reassessed, with new material and full details on litle-known candidates. The three suspects named in 1894 are exonerated, and there is a complete rebuttal of the so-called Maybrick Diary. Philip Sugden's studies challenge the whole drift of Ripper studies since 1959, and raise the possibility of an American connection in the case.
