From the critically acclaimed author of The Book of Chocolate, The Human Body, and From Here to There, comes an all new nonfiction deep dive into forensic science. What is evidence and how do investigators gather it? How do you determine how long a body has been dead? Do fingerprints differ from person to person? How did some of the world's great fictional detectives, like Sherlock Holmes, further the study of forensics? Packed with lively photos, classroom activities, and engaging prose, budding private eyes and scientists will be eager to find the answers to these and other questions in HP Newquist's latest, and to learn about everything from the world's first autopsy in Ancient Rome to the role that DNA plays in solving crimes along the way.
