Francesa Simon: Salka

My guest in this week’s Book Club is Francesca Simon. Best known for her Horrid Henry series of children’s books, Francesca has just published her first novel for grownups, a haunting reworking of a Welsh folk tale called Salka: Lady of the Lake. She tells me how she came to shift direction, what myths offer in terms of storytelling possibility – and why she never tired of her best-known creation.
