In this series of The Essay, recorded this week in front of an audience at Hay Festival, five writers explore The Art of Storytelling. The writers include linguist Professor David Crystal, broadcaster and musician Clemency Burton-Hill, artist and memoirist Edmund de Waal and Shakespeare scholar Professor Emma Smith.

Today novelist and short story writer Jon Gower reflects on lessons learned from a master storyteller - his grandfather - and recalls an encounter with The Lady of the Lake.

Part of Radio 3's week-long residency at Hay Festival, with programmes In Tune, Lunchtime Concert, Free Thinking and The Verb all broadcasting from the Festival.
