Peter Sutcliffe, the Yorkshire Ripper, is one of the most notorious killers in British history. Held in Broadmoor Psychiatric Hospital, he is one of a handful of prisoners who will never be free. Official record has it that he was convicted of murdering thirteen women. He claimed he had a divine mission to killthem. But this is far from the full story - indeed, almost everything we know about the Ripper is wrong. Three years of investigation by retired police officer Chris Clark and veteran journalist Tim Tate has uncovered seismic holes in the case with truly shocking repercussions.
