The chapters are organized more or less chronologically, so readers can easily discern the progression of criminal-investigation techniques throughout history and in a variety of international cultures. A strength of the book is its global approach; so many other books about forensic science are United States–centric. That said, because of its haphazard organization within each chapter, as a narrative, the book is difficult to follow. Still, Ramsland’s book holds discoveries for every CSI buff. From the development of fictional detective Sherlock Holmes to the invention of lie-detection machines to the teasing out of DNA, Ramsland comfortably guides the reader through crime-solving land. — S.W.
