As one of the UK's leading forensic scientists, Mike Silverman has helped to identify and convict dozens of murderers, rapists, armed robbers, burglars and muggers, thanks to the evidence they - or their victims - unwittingly left behind at the scenes of their crimes. Mike Silverman started his career in the days when fingerprints were still kept on card files and DNA profiling was just a pipe dream, so Written in Blood is more than just a casebook - it is also a definitive history of the development of forensic science over the course of the past thirty-five years. From collecting blood samples at gangland executions to investigating forensic science failings, including in the murders of Rachel Nickell and Damilola Taylor, Mike Silverman's unique career provides a fascinating insight into the ways forensic science is used to help solve real-life crimes. Packed with genuine crime scene photographs and original sketches, Written in Blood is the ultimate insider's account of the fascinating world of forensic science.
