Great detectives can use logic and intuition to solve crimes, but often that's not enough. That's when they turn to scientists for help. Forensic scientists use an astonishing variety of techniques on the smallest clues to reveal exactly who committed a crime. This book describes how different evidence - from blood to blowflies - is used to catch even the smartest crooks. And you can read exciting true crime comic strips that show how scientists have foiled criminals time and time again. Ages: 10 years and up Size of book: 6 3/4 x 9 1/4 inches Pages: 96
