Back in 1933, in the Berkeley Hills of California, there was a private laboratory filled with rare objects - beakers, microscopes, Bunsen burners and hundreds of books... The owner of the laboratory was Edward Oscar Heinrich, the pioneer of forensic science in the United States. Heinrich was America's first expert witness and solved at least 2,000 cases during his 40-year career. He is good at finding clues, establishing evidence, and deducing the correct answer with a seemingly super-powerful thinking technique. He also pioneered many forensic identification methods that are still in use today, such as blood stain analysis, ballistic analysis, latent fingerprint extraction and analysis, etc., Permanently changing the way criminal investigations are conducted, and is known as the "American Sherlock Holmes". This book combines real cases, scientific investigation, and insights into human nature, recreating that era when technology was far less developed than modern times. Heinrich's great wisdom allows us to understand his profound impact on crime scene investigation and the legal system, examine the chaotic history of criminal investigation, and glimpse the difficult birth of forensic science.
