Jack the Ripper is history's most infamous serial killer. He was never identified, he hid the mystery amongst Victorian London's fog in 1888; a killer that murdered five women in a short space of time, between the end of summer and the beggining of autumn 1888, in the district of Whitechapel. Only to disappear and leave behind the intrigue and mystery that lasts in our days. 45.500 days have passed, 125 years since Jack murdered his five canonical victims and the evidence has always been right in front of us. Using police techniques from the 21st Century, and after four years of investigation and analysis of the crime scenes and the clues left by the killer, this book shows the police investigation that breaks down the facts and clues and concludes in the only possible solution: the police report that includes the evidence of Jack the Ripper's true identity. A book that will not leave anyone indifferent.
