A 13th century picture of Christ, strikingly similar to that on the Turin Shroud, has turned up. It's believed to belong to the Knights Templar, a medieval order of monks who gave their name to the village of Templecombe. The team investigate a manor house thought to be on the site of a monastery. What's left of the monastery, and who were the Templars anyway? So far all the evidence seems to be outside the house, where Phil and the team have already dug up pieces of encaustic tile.
