Zoom in on ... crime scene clues

Did you know blowflies can smell a dead body from 16 km (10 miles) away? Or that a person sheds up to 40,000 skin cells every minute? Or that a single hair can tell you if a victim was poisoned?This book zooms in on tiny things - such as hair, skin, broken glass and dust - that reveal the truth about crimes.

Learn about the bacteria that tell forensic scientists where someone was killed, and meet the maggots that tell police the time of death of dead bodies. The Zoom In On series shines a powerful light on a world so small that it's normally invisible.

Scientists can zoom in on the strange creatures that live there.

Now you can look down the microscope and see them too, if you dare...
