Philipp Röttgers is an author who has written about Jack the Ripper and the Whitechapel murders. Phillips book titled "Jack the Ripper – Die Whitechapel-Morde 1888: Eine Chronologie" was written after being inspired by conversations he had during lectures and tours of London's East End. Paul Begg, a leading Ripper expert, called it a "must-have" book for anyone interested in the mystery. Phillip joins me to discuss the fact vs myth aspect of the case and what is proven and what is speculation done by authors and media forms.
