What could the mysterious circular anomaly be? Time Team geophysicist John Gater has scanned an area near the iconic neolithic site of The Ness of Brodgar. An intriguing circular pattern has revealed itself in the data, but what is it? Helen Geake shares her theory with co-host Martyn Williams. Time Team's Jackie McKinley also has her own idea of what might be hidden beneath Orkney. She shares her thoughts as she prepares to travel to the site herself.
