Title: UNBELIAVABLE RESEARCH!! A MASTER IN HISTORICAL RESEARCH!!
Review: Sudgen did the impossible: he researched hard, going straight into the original sources, without depending on other books about the subject. Along the way, he pratically destroyed every suspicion put upon determined suspects, and ends the book without giving a plausible supesct, altough pointing to George Chapman, minly because he was, afetr 1903, the main suspect to detective Abberline.
