For more than 100 years, police and Ripperologists have tried in vain to put a name to the faceless silent killer. In 1975, Richard Whittington-Egan published
A
Casebook on Jack the Ripper
, now eagerly sought but long out of print and only obtainable at mammoth prices, in which he documented the history, the crimes, the investigations, the investigators, and added his new discoveries. Now, in a completely revised and very considerably enlarged edition of the 1975 Casebook, he has taken a new look, from a longer perspective, at the theories and the personages who advanced them, from the time of the murders up to the present day.
