Melvin Harris was instrumental in exposing the so-called Ripper Diaries. Drawing on newly uncovered material on the man and the murders, and using modern FBI methods of tracing serial killes, Harris builds a case against the man he names as the true Ripper; a man who was interviewed by police at the time, and had inside information on the killings. The book also includes the memoirs of Baroness Cremers, the business partner of the man named. Harris is the author of Jack the Ripper: the Bloody Truth.
