In a Geography lesson like no other, DI Greg James and DCI Bella Mackie investigate how human bodies can be preserved for thousands of years, with the help of Superintendent McCulloch.

Together, they will look at some of the famous cases of naturally preserved human bodies from history - including the Tollund Man, King Tut and the plaster casts of Pompeii - to find out how they died and why their bodies were so well-preserved for so many years. They'll look at how decomposition works and the factors that can speed it up or slow it down; and along the way they'll discuss the carbon cycle, how fossil fuels are formed, and find out what it's like to be caught in a volcano's pyroclastic flow...

Bad students of all ages are welcome. Expect brilliant teachers, captivating subjects but absolutely no homework.
