In a close examination of an assault victim's body, a forensic physician can 'read' the terrible alphabet that fists and weapons have written across it. A crime scene investigator notes the tiny indentations on the fragments of a tin can identified at a bomb site, enabling him to find the can opener that made them - and the bomb-maker who used it. A forensic dentist identifies the thief who dropped some chewing gum, with his teeth marks in it, during a burglary. Liz Porter's riveting casebook shows how forensic investigators - including pathologists, chemists, entomologists, DNA specialists and document examiners - have used their expertise in dozens of fascinating crimes and mysteries.
