Detailing the advances made in the various branches of forensic medicine in the fight against crime, and in particular murder, this book draws on case histories to illustrate the enormous improvements in forensic science over the last hundred years. These have reached a point where a killer can be identified by a single hair or a bitemark, or even a twist of fibre. Fingerprinting, blood-typing, ballistics, toxicology and the latest psychological profile techniques are all included in this catalogue of detection, which demonstrates that it is increasingly difficult to get away with murder.
