Forensic science is one of the most powerful tools in any criminal investigation. The impartial and objective evidence it provides can help to exonerate the innocent and incarcerate the guilty.

During her remarkable career, she has established and run forensic science laboratories and has worked on thousands of cases in the UK and across the world. Whether it's looking at blood patterns and footwear marks at crime scenes to work out what happened, extracting data from suspects' mobile phones to discover where they were at criticial times, or analyzing fragments of textile fibers, glass or paint to determine where they might have come from, Gallop shows every contact really does leavea a trace, and every trace can help to solve a crime. With unpraralleled access and insight across a wide range of specialties, How to Solve a Crime is a fascinating, definitive and authoritative account of real-life forensic science. -- Adapted from front book jacket flap.
