Helen Geake and Martyn Williams chat to Time Team's landscape archaeologist Stewart Ainsworth. He's working with Cheshire Police to tackle so-called heritage crime. With the help of PC Jono Lightfoot he'll explain how techniques used by archaeologists could be the key to catching the criminals.

Martyn visits Professor Henry Chapman at The University of Birmingham to find out more about his work on bog bodies and Suzy Watts from the National Trust has an update on what's been going on at the Attingham estate, where Time Team's Matt Williams has been trying to discover the secrets of a huge abandonded Roman city.

Helen will also answer more questions from Time Team members. To submit yours and find out more about the perks you get for supporting Time Team, head to patreon.com/timeteamofficial.
