Solving a crime often comes down to forensic science – but what exactly is it, and how does it work? Explore the fascinating, and sometimes gory, world of forensics, where science helps crack the case. How do you know if a red stain is blood or ketchup – and whose blood it might be? Can computers really recognise your face in a crowd? Why are fingerprints so important to an investigation? Learn why securing a crime scene quickly is so critical, and how DNA sampling actually works. Find out how maggots can reveal how long someone has been dead, or how a single fabric fibre can lead investigators to a murderer. From the scene of the crime to testing in the laboratory, readers discover how every clue is pieced together to tell a story and reveal the guilty party. Find out how methods have changed since the days of Sherlock Holmes, the latest technology in use today, and the techniques of the future. Flip to the reference section to learn about pioneers in the field, see a timeline of forensic firsts, and find museums and special websites for further inspiration and exploration, while the glossary supplies all the vocabulary needed to sound like a genuine CSI expert.
