This time, Susan and campervan bestie Helen Mirren are exploring the beautiful Cotswolds, famously the inspiration for romantic novelist, Jilly Cooper.

The comedian embarks on a quest through Somerset, hunting for signs of King Arthur. Susan's trip starts at Glastonbury Abbey, which claims to be the site of his tomb. Next, Susan's volunteering on England's longest heritage rail line - the West Somerset Railway. At a forge outside Glastonbury, the presenter hears how the most famous sword in history - Excalibur - might have been made. Then, she uncovers another local legend - John Haynes, he man behind the iconic Haynes car manuals.
