Our guest today is Rachael Stirling: the brilliant theatrical actress and one of the stars of BBC comedy Detectorists, who is currently on stage in London in Giant, about the writer Roald Dahl.

Gyles and Rachael begin by talking about a memorable conversation Gyles had with Rachael's mother, the great actress Dame Diana Rigg, when he interviewed her 25 years ago. And this interview with Rachael is no less memorable: it's a fascinating discussion of her childhood, her complex relationship with her mother, and her parents' divorce. It's a frank discussion of her first sexual experiences and her boarding school days (NB this episode is more graphic than our usual, with sexual refs and some swearing). And, finally, it's a moving discussion of Rachael's experiences as her mother's carer in the final months of her life.

This is a special and very touching episode, thank you so much to Rachael.

Rachael Stirling is currently playing Felicity Crosland in Giant, about the writer Roald Dahl, at the Harold Pinter Theatre in London. It's on for the rest of the summer and tickets are available here.
