Martin and Roman Kemp continue their travels in the counties of Meath and Dublin. In the Boyne Valley they come face to face with an ancient tomb, where they encounter what might be the earliest depiction of a human face. At the Hill of Tara they meet an arch druid and have a profound sound bath, then explore a spooky ruin reputed to have once been the meeting place of Dublin's infamous Hellfire Club. Martin is also reunited with the owner of Slane Castle, who was a child when Martin last saw him in his Spandau Ballet days.
