While many set out to commit the perfect crime and ultimately fail by being caught and convicted, there are a plethora of unsolved cases throughout history. Unsolved Crimes takes a look at numerous unsolved homicides committed throughout the 20th century as well as some carefully planned robberies that still leave the authorities stumped many years later. This book provides a fascinating insight into some of the most riveting cases of the past 100 years including the Black Dahlia, Julia Wallace, Peter Falconio - the British backpacker who disappeared in the Australian outback in July 2001 - and high profile murders such as Jill Dando, Stephen Lawrence, Suzy Lamplugh, Carl Bridgewater and Genette Tate. Serial killers such as Jack the Stripper, the Zodiac Killer and Bible John are investigated as well as the Babes in the Wood killings that horrified the nation and the mysterious deaths of Rudolf Diesel, Natalie Wood and Robert Maxwell are scrutinised. These, and many other cases, still continue to baffle and challenge all those involved and provide a fascinating backdrop to crimes of the 20th century and beyond.
